Experimental Assessment of ABNO-driven Multicast Connectivity in
Flexgrid Networks
Abstract:
The increasing demand of internet services is pushing cloud services
providers to increase the capacity of their data centers (DC) and create DC
federations, where two or more cloud providers interconnect their
infrastructures. As a result of the huge capacity required for the inter-DC
network, the flex grid optical technology can be used. In such scenario,
applications can run in DCs placed in geographically distant locations and
hence, multicast-based communication services among their components
are required. In this paper, we study two different approaches to provide
multicast services in multi-layer scenarios assuming that the optical
network is based on the flex grid technology: i) establishing a point-to-
multipoint optical connection (light-tree) for each multicast request, and ii)
using a multi-purpose virtual network topology (VNT) to serve both
unicast and multicast connectivity requests. When that VNT is not able to
serve an incoming request as a result of lack of capacity, it is reconfigured
to add more resources. A control plane architecture based on the
Applications-based Network Operations (ABNO) one, currently being
standardized by the IETF, is presented; workflows are proposed and PCEP
extensions are studied for the considered approaches. The experimental

validation is carried-out on a testbed set-up connecting Telefonica, CNIT,
and UPC premises.
Existing System:
Some applications might require group communication services (one-to-
many or many-to-many) among their distributed components. Although
point-to-point (p2p) connectivity can be used thus, copying contents to
each of the destinations, point-to-multipoint (p2mp) connections might fit
better to this purpose.
The new capacity demands advocate for an evolution towards optical
transport-based solutions for DC interconnection [2]. In this area, the
flexgrid optical network technology is being extensively investigated
because of its inherent spectrum efficiency and connection flexibility.
Proposed System:
In this paper we assume that the Application-Based Network Operations
(ABNO) architecture is used. The DCs participating in the communication
are considered to be part of a federation. As such, a cloud management
system at federation level is in charge of managing intra-DC resources.
Typically, one or more core Ethernet programmable switches within each
DC are connected to the flexgrid optical core network providing the
necessary interconnection among the DCs in the federation. The necessary
coordination between the cloud management system in each DC and the
ABNO based transport network control element is performed by a
differentiated software element, named as Application Service Orchestrator

(ASO), acting as an end-to-end orchestrator and responsible of translating
the connectivity requests from the DCs to the ABNO element.

Experimental assessment of abno driven multicast connectivity in flexgrid networks

This document proposes an automated dynamic offset approach for network selection in heterogeneous networks. The approach uses a hierarchical Bayesian game framework where the macro cell dynamically chooses an offset for the reported channel quality to guide users to intelligently select between the macro cell and small cell networks. The model is analyzed to derive the utilities and equilibria, and is shown to optimize the global network utility while users maximize their individual utilities. A key contribution is developing a polynomial time algorithm to determine the dynamic offset value at equilibrium. Simulation results show the proposed hierarchical mechanism maintains a price of anarchy close to 1, even for a small number of users, which is better than a non-cooperative model.

Energy Behavior in Ad Hoc Network Minimizing the Number of Hops and Maintaini...CSCJournals

Wireless ad-hoc mesh network is a special kind of network, where all of the nodes move in time. The topology of the network changes as the nodes are in the proximity of each other. Ad-hoc networks are generally self-configuring no stable infrastructure takes a place. In this network, each node should help relaying packets of neighboring nodes using multi-hop routing mechanism. This mechanism is needed to reach far destination nodes to solve problem of dead communication. This multiple traffic "hops" within a wireless mesh network caused dilemma. Wireless mesh network that contain multiple hops become increasingly vulnerable to problems such as energy degradation and rapid increasing of overhead packets. This paper provides a generic routing framework that balances energy efficient broadcast schemes in Wireless (Ad-Hoc) Mesh Network and maintaining connectivity of nodes (mobile terminals). Typically, each node’s activities will consume energy, either for sending packets, receiving or preparing/processing packets. Number of hops, distance of nodes, and size of packet will determine the consumption of energy. The framework is based on the principle that additional relay nodes with appropriate energy and routing metric between source and final destination significantly reduces the energy consumption necessary to deliver packets in Wireless (Ad-Hoc) Mesh Network while keep the connectivity of dynamic nodes. Using the framework, the average network connectivity is kept 18% higher and the lifetime of network lasting more than 2.38% compared with network with Link State Routing mechanism. The simulation notes that the end-to-end delay may increase rapidly if relay nodes are more than five.

A NEW DATA ENCODER AND DECODER SCHEME FOR NETWORK ON CHIPEditor IJMTER

System-on-chip (soc) based system has so many disadvantages in power-dissipation as well as clock rate while the data transfer from one system to another system in on-chip. At the same time, a higher operated system does not support the lower operated bus network for data transfer. However an alternative scheme is proposed for high speed data transfer. But this scheme is limited to SOCs. Unlike soc, network-on-chip (NOC) has so many advantages for data transfer. It has a special feature to transfer the data in on-chip named as transitional encoder. Its operation is based on input transitions. At the same time it supports systems which are higher operated frequencies. In this project, a low-power encoding scheme is proposed. The proposed system yields lower dynamic power dissipation due to the reduction of switching activity and coupling switching activity when compared to existing system. Even-though many factors which is based on power dissipation, the dynamic power dissipation is only considerable for reasonable advantage. The proposed system is synthesized using quartus II 9.1 software. Besides, the proposed system will be extended up to interlink PE communication with help of routers and PE’s which are performed by various operations. To implement this system in real NOC’s contains the proposed encoders and decoders for data transfer with regular traffic scenarios should be considered.

This thesis analyzes the capacity of hybrid wireless networks with dedicated relays. Two hybrid network models are introduced for load balancing and interference reduction, where dedicated relays positioned at cell borders wirelessly connect to base stations. Analytical approaches are used to obtain the probability of blocking and outage for the models, demonstrating the effectiveness of the hybrid solutions. A signal to interference ratio call admission control scheme is also analyzed for a hybrid CDMA network. Numerical results verify the extensive gain obtained from ad hoc relaying over conventional CDMA networks with this control scheme.

This document discusses a proposed mechanism for cooperative load balancing and dynamic channel allocation in cluster-based mobile ad hoc networks. The mechanism aims to improve bandwidth efficiency and performance for non-uniform traffic loads. It utilizes clustering, dynamic channel allocation, and cooperative load balancing to reduce energy consumption, increase throughput, and decrease inter-packet delay variation. Extensive simulations showed the proposed approach improves bandwidth efficiency compared to protocols without these mechanisms, as well as compared to IEEE 802.15.4 and 802.11 protocols.

IRJET- Study on Hierarchical Cluster-Based Energy-Efficient Routing in Wi...IRJET Journal

This document discusses energy-efficient hierarchical cluster-based routing protocols for wireless sensor networks. It begins by introducing wireless sensor networks and explaining that energy efficiency is a key challenge due to limited battery power. It then discusses clustering structures commonly used in wireless sensor networks, including hierarchical clustering where clusters form larger clusters in a tree structure. The document goes on to describe several hierarchical cluster-based routing protocols - LEACH, PEGASIS and TEEN - and compares their approaches to routing data to extend network lifetime. It concludes that these protocols each have advantages and disadvantages depending on the network topology, and that cluster formation and communication between clusters requires further research.

Latest Research Topics On Flying Ad-Hoc Networks (FANETs):Thesis Scientist Private Limited

One of the most important design problems for multi-UAV (Unmanned Air Vehicle) systems is the communication which is crucial for cooperation and collaboration between the UAVs. If all UAVs are directly connected to an infrastructure, such as a ground base or a satellite, the communication between UAVs can be realized through the in-frastructure. However, this infrastructure based communication architecture restricts the capabilities of the multi-UAV systems. Ad-hoc networking between UAVs can solve the problems arising from a fully infrastructure based UAV networks. In this paper, Flying Ad-Hoc Networks (FANETs) are surveyed which is an ad hoc network connecting the UAVs. The differences between FANETs, MANETs (Mobile Ad-hoc Networks) and VANETs (Vehicle Ad-Hoc Networks) are clarified first, and then the main FANET design challenges are introduced. Along with the existing MANET protocols, open research issues are also discussed.

BIO-INSPIRED SEAMLESS VERTICAL HANDOVER ALGORITHM FOR VEHICULAR AD HOC NETWORKSijwmn

One of the most important factors to implement VANET is by considering the variety of wireless networks available around the city as well as the vehicles traffic scenarios. However, by providing a diverse range of wireless access technologies, it is necessary to provide continuous network connectivity as well as selecting the most suitable network technology and performance. Many researchers have worked on building algorithms for selecting the best network to improve the handover process. However, with high-speed vehicles mobility, the vertical handover process became the most challenging task in order to achieve realtime network selection. This paper proposes a bio-inspired network selection algorithm influenced by insect's behaviour which combines Artificial Bee Colony (ABC) and Particle Swarm Optimization (PSO). The proposed algorithm is applied to process multi-criteria parameters to evaluate the best available network and then execute the handover process seamlessly. The results demonstrate the benefits of the proposed Multi-Criteria ABC-PSO method by reducing the handover decision delays by 25%. It gives the optimum performance in terms of network selections and reduces the handover latency by 14.5%. The proposed algorithm also reduces the number of unnecessary handovers by 48% for three different mobility scenarios based on traffic environments (highway, urban and traffic jam).

An Adaptive Cluster Based Routing Protocol for WSNEswar Publications

The Wireless sensor networks (WSN) consisting of a large number of sensors that are effective for gathering data in a variety of environments, as the sensor operate on battery which is of limited power. To support high scalability and better data aggregation in fixed base station communication, sensor nodes are often grouped into disjoint, non overlapping subsets called clusters. Clusters create hierarchical WSN which incorporate efficient utilization of limited resources of sensor nodes. These clusters are formed by specialized cells. Each cluster is managed by a special node called cluster head and advanced node. An algorithm for better cluster head selection based on the node energy and the distance from base station to the cluster head for the efficient transmission and to reduce energy consumption by the sensor nodes is proposed in this paper. And the same algorithm is compared with the LEACH algorithm in terms of energy consumption.

This document discusses clustering in wireless sensor networks. It begins with introducing wireless sensor networks and describing their architecture and applications. It then discusses the objective of clustering in wireless sensor networks, which is to minimize energy dissipation and maximize network lifetime. Various clustering algorithms are described, including LEACH and EEUC. EEUC is an energy-efficient unequal clustering algorithm that forms clusters of unequal size to reduce energy consumption of nodes farther from the base station. The document concludes that EEUC helps balance energy consumption among nodes and improves network lifetime.

GPSFR: GPS-Free Routing Protocol for Vehicular Networks with Directional Ante...ijwmn

Efficient and practical communications between large numbers of vehicles are critical in providing high level of safety and convenience to drivers. Crucial real-time information on road hazard, traffic conditions and driver services must be communicated to vehicles rapidly even in adverse environments, such as “urban canyons” and tunnels. We propose a novel routing protocol in vehicular networks that does not require position information (e.g. from GPS) but instead rely on relative position that can be determined dynamically. This GPS-Free Geographic Routing (GPSFR) protocol uses the estimated relative position of vehicles and greedily chooses the best next hop neighbor based on a Balance Advance (BADV) metric which balances between proximity and link stability in order to improve routing performance. In this paper, we focuses primarily on the complexity of routing in highways and solves routing problems that arise when vehicles are near interchanges, curves, and merge or exit lanes of highways. Our simulation results show that by taking relative velocity into account, GPSFR reduces link breakage to only 27% that of GPSR in the dense network. Consequently, GPSFR outperforms GPSR in terms of higher data delivery ratio, lower delay, less sensitivity of the network density and route paths’length

Air ground integration approachSeyed Ahmad Soleymani

The document proposes an air-ground integrated mobile edge computing (MEC) framework to address challenges posed by growing demands for massive connectivity, ultra-low latency, and high reliability in emerging IoT applications. The framework conceives a new MEC approach from an air-ground integration perspective by systematically integrating communication, computing, and storage resources from both air segments (e.g. unmanned aerial vehicles) and ground segments (e.g. vehicles). This provides on-demand deployment of edge servers for efficient resource utilization and reliable service provisioning. The framework architecture and its technological benefits, such as enhanced connectivity, adaptive resource allocation, differentiated quality of service guarantees, and effective mobility management, are then described.

Hierarchical Coordination for Data Gathering (HCDG) in Wireless Sensor NetworksCSCJournals

A wireless sensor network (WSN) consists of large number of sensor nodes where each node operates by a finite battery for sensing, computing, and performing wireless communication tasks. Energy aware routing and MAC protocols were proposed to prolong the lifetime of WSNs. MAC protocols reduce energy consumption by putting the nodes into sleep mode for a relatively longer period of time; thereby minimizing collisions and idle listening time. On the other hand, efficient energy aware routing is achieved by finding the best path from the sensor nodes to the Base Sta-tion (BS) where energy consumption is minimal. In almost all solutions there is always a tradeoff between power consumption and delay reduction. This paper presents an improved hierarchical coordination for data gathering (HCDG) routing schema for WSNs based on multi-level chains formation with data aggregation. Also, this paper provides an analytical model for energy consumption in WSN to compare the performance of our proposed HCDG schema with the near optimal energy reduction methodology, PEGASIS. Our results demonstrate that the proposed routing schema provides relatively lower energy consumption with minimum delay for large scale WSNs.

Energy Efficient Clustering Algorithm based on Expectation Maximization for H...IRJET Journal

This document presents a new energy efficient clustering algorithm for homogeneous wireless sensor networks based on the Expectation Maximization algorithm. The key points are: 1. The algorithm uses unequal clustering where clusters closer to the base station are smaller to balance the network load. 2. Cluster head selection is done using the Expectation Maximization algorithm, which is shown to improve results over LEACH, PEGASIS, and PLEACH protocols. 3. Simulation results in MATLAB demonstrate that the proposed algorithm significantly decreases the number of dead nodes and energy consumption per round compared to existing algorithms.

Energy Consumption in Ad Hoc Network With Agents Minimizing the Number of Hop...CSCJournals

Wireless mobile ad-hoc network (MANET) is a special kind of network, where all of the nodes move in time. Node is intended to help relaying packets of neighboring nodes using multi-hop routing mechanism in order to solve problem of dead communication. MANET which engages broadcasting and contains multiple hops becomes increasingly vulnerable to problems such as mobile node’s energy degradation, routing problem and rapid increasing of overhead packets. This paper provides an extensive study of energy consumption in the MANET that consists of several network areas with the presence agents. Agents will minimize number of hops and its affect in linearity with the delay. As nodes grow, either in data transmission services or coverage of node’s communication or more agents stand in overlapped locations, accordingly data exchange and topology development to adapt the network are becoming an important issue. As a result, agents are needed to support process automation, high-level connectivity and intelligent service on that such environment. We evaluate the agents’ performance and network energy consumption for supporting MANET. The proposed agents provides service packets transmission between networks; e.g. determine appropriate relay nodes dynamically, maintain the transmission between networks through another nodes, share the topology knowledge among agents, and route packets between source and final destination that are unable to communicate directly. The achievement on research with this approach is conducted via simulation study. A similar network without agents is presented to derive such referential bounds by using appropriate functions of network agents. The proposed algorithm is confirmed with composite simulation results.

78 ieee analysis of power consumption in future high capicity network nodesengrarif

This document analyzes power consumption in future high-capacity network nodes. It discusses how increasing network capacity will unavoidably lead to higher power consumption. It examines different architectures based on packet-switched and circuit-switched designs using either all-electronic or all-optical implementations. The total power consumption of realistic future core network nodes would likely fall between these extremes. Circuit switching is generally more power efficient than packet switching, and could help relax scalability limitations due to power. Both electronic and optical technologies may enable very high capacity network nodes in the future depending on the architecture.

Topology abstraction service for ip vp nsEcway Technologies

VPN service providers have traditionally kept their network topology private from IP-VPN customers, limiting interaction between them. This document proposes a Topology Abstraction (TA) service that provides controlled visibility of the service provider's network to VPNs. The TA service generates abstracted views of the network for each VPN accurately and fairly. Three decentralized schemes are developed to generate TAs with different performance characteristics, improving call performance for VPNs, fair resource sharing, and higher network utilization for the service provider. Simulation results validate the TA service concept and evaluate the proposed techniques over various network topologies.

It notes that 59% of organizations lack resources to validate vendor claims, and organizations need methods to validate network resiliency using real traffic loads and security attacks. It then provides an overview of a traditional secure data center design with two main components: 1) the physical network fabric and 2) the virtual fabric and compute environment. It shows how this design establishes internal secure zones without crossing the core network, and incorporates virtual security services. Finally, it gives examples of traditional secure use cases such as separating internal and external zones, and securing application tiers.

Multicloud as the Next Generation of Cloud Infrastructure Brad Eckert

So, what are data center networks really built for? Short answer "applications". Whether it is a public cloud provider, private enterprise, FSI or telco cloud - the nature of applications across each data center type impose a different set of demands on the underlying network infrastructure. A next-generation architecture is one that is versatile yet modular enough to address these different application needs, whether these are HPC and Big Data, legacy or real-time content. A common architecture goal is for a unified and consolidated network design that can leverage standardized technology attributes and can integrate a versatile workload environment be it high-performance bare metal servers to a microservices enabled container environment. This tutorial is aimed at an in-depth structured understanding of data center business and technical requirements and how EVPN-VXLAN constructs serve as a swiss-knife approach to achieve the same. Practical case study examples that translate theoretical concepts into building blocks for designing and automating multi-tenant data center deployments. Explore how a unified technology solution can help build a network that grows with increasing east-west traffic, seamlessly connects with the backbone for north-south communication while leveraging familiar protocol concepts to achieve security insertion. We will also go over operator issues with traffic optimization, multicast and BUM traffic handling and other common pitfalls. A final step would be to define requirements for a cohesive solution using a centralized controller that enables a data center network operator to leverage the same degree of agility and visibility for both the physical network and the application infrastructure to truly build a software-defined data center.

This document discusses data center interconnect (DCI) solutions for extending layer 2 domains across multiple sites. It introduces Overlay Transport Virtualization (OTV) as an IP-based solution that uses "MAC in IP" techniques to extend layer 2 connectivity over any transport network while containing failures and preserving resiliency. OTV uses control-plane learning and IS-IS routing to advertise MAC reachability between sites and elect a single edge device per VLAN to forward traffic. This allows OTV to provide layer 2 extensions across metro or global distances while isolating spanning tree domains and preventing unknown unicast flooding beyond site boundaries.

Managing Cloud networking costs for data-intensive applications by provisioni...Igor Sfiligoi

Presented at PEARC21. Many scientific high-throughput applications can benefit from the elastic nature of Cloud resources, especially when there is a need to reduce time to completion. Cost considerations are usually a major issue in such endeavors, with networking often a major component; for data-intensive applications, egress networking costs can exceed the compute costs. Dedicated network links provide a way to lower the networking costs, but they do add complexity. In this paper we provide a description of a 100 fp32 PFLOPS Cloud burst in support of IceCube production compute, that used Internet2 Cloud Connect service to provision several logically-dedicated network links from the three major Cloud providers, namely Amazon Web Services, Microsoft Azure and Google Cloud Platform, that in aggregate enabled approximately 100 Gbps egress capability to on-prem storage. It provides technical details about the provisioning process, the benefits and limitations of such a setup and an analysis of the costs incurred.

Most have focused on topology, architecture, flow scheduling, and virtualization but not FPGA-based acceleration. 3. The document argues that an FPGA-based spine-leaf model could be an alternative to traditional network models for enterprise applications like EETACP, offering benefits like lower latency, offloading, scalability, and

Cloud Based Datacenter Network Acceleration Using FPGA for Data-Oﬄoading Onyebuchi nosiri

Currently, the high-performance processors in Spine-Leaf, Mesh, and Router layer-3 (SLMR-3) backend server domain have multiple cores, but data offloading from processor to the peripheral is not keeping pace with the required Quality of Service (QoS) needed to balance the workload on a Warehouse Scaled Computer (WSC) running a developed Enterprise Energy Tracking Analytic Cloud Portal (EETACP) data center network. High speed with low latency interconnects between the processors and Field Programmable Gate Array (FPGA) is critical for achieving performance benefits in EETACP deployment. Most of the servers in WSC architectures are running at average utilization rates and perform well under peak processing power. These servers are good candidates for FPGA processors in cloud-based data centers owing to its acceleration coherency. This paper made a strong case for cloudbased support for EETACP. An FPGA-based Spine-Leaf model is proposed to be an alternative to traditional network models for EETACP provisioning. The paper analyzed reconfigurable FPGAs, characterized a simplified process model for hyperscale FPGA cloud design description. To validate the performance, comparisons was made with two similar networks, namely DCell and BCube for enterprise application deployments. It was concluded that FPGA-based DCN acceleration for EETACP offers acceptable QoS expectations

The telecommunications landscape is undergoing major changes with the introduction of SDN and NFV, which allow new ways of designing networks and deploying network functions. Accurately describing the services to be provided is crucial for integrating and ensuring interoperability between different NFV proposals. However, fully realizing the benefits of NFV presents unique challenges that the current service description proposals do not fully address. This paper reviews current NFV service description proposals, identifies key challenges, and proposes a straw man model for service and resource description that could guide future initiatives in addressing these challenges.

Power optimization with bler constraint for wireless fronthauls in c ranieeepondy

This document proposes two power optimization techniques for wireless fronthauls in cloud radio access networks (C-RAN) that minimize energy consumption at remote radio heads while satisfying quality of service constraints. It derives a closed-form upper bound on system block error rate via union bound analysis. Then, it proposes adaptive transmission schemes and practical power optimizations based on both block error rate and pair-wise error probability to reduce energy use at remote radio heads while meeting a predefined non-zero block error rate quality of service requirement.
