1) Computer networks allow communication and sharing of resources between computer systems and devices through communication channels. There are several types of networks including LANs, WANs, and MANs. 2) For communication between systems, both must agree on a protocol which sets rules for data transmission. The two main protocol stacks are OSI and TCP/IP. 3) The network layer is responsible for delivering packets from source to destination. It uses services from the data link layer and provides services to the transport layer. Common network layer protocols are IP (Internet Protocol) for connectionless service and MPLS for connection-oriented service.

Sliding window protocolShehara Abeythunga

This document describes the sliding window protocol. It discusses key concepts like both the sender and receiver maintaining buffers to hold packets, acknowledgements being sent for every received packet, and the sender being able to send a window of packets before receiving an acknowledgement. It then explains the sender side process of numbering packets and maintaining a sending window. The receiver side maintains a window size of 1 and acknowledges by sending the next expected sequence number. A one bit sliding window protocol acts like stop and wait. Merits include multiple packets being sent without waiting for acknowledgements while demerits include potential bandwidth waste in some situations.

Routing algorithm network layersambhenilesh

The document provides an overview of different routing algorithms: - It describes shortest path routing and discusses properties like optimality, simplicity, and robustness that routing algorithms should have. - Common routing algorithms are described briefly, including flooding, distance vector routing, link state routing, and hierarchical routing. - Specific routing algorithms like Dijkstra's algorithm, flow based routing, and link state routing are explained in more detail through examples. - Issues with distance vector routing like the count to infinity problem are also covered. - The talk concludes with hierarchical routing being presented as a solution for scaling routing to larger networks.

Error Detection And CorrectionRenu Kewalramani

The document discusses error detection and correction techniques used in data communication. It describes different types of errors like single bit errors and burst errors. It then explains various error detection techniques like vertical redundancy check (VRC), longitudinal redundancy check (LRC), and cyclic redundancy check (CRC). VRC adds a parity bit, LRC calculates parity bits for each column, and CRC uses a generator polynomial to calculate redundant bits. The document also discusses Hamming code, an error correcting code that uses redundant bits to detect and correct single bit errors.

Stop and-wait protocolVenkata Sreeram

This document discusses the stop-and-wait protocol. It provides flow control by allowing only one frame to be transmitted at a time before waiting for an acknowledgment. However, it does not provide error control. The key aspects are: 1. It is used for unidirectional data transmission over noiseless channels. 2. It only allows one frame to be transmitted at a time before waiting for an acknowledgment, providing flow control but no error control. 3. A disadvantage is that if a frame is lost or corrupted, both the sender and receiver will be stuck indefinitely waiting.

Flow control in Computer NetworkAhtesham Ullah khan

Error controlBhupendra sahu

Error control techniques allow for detection and correction of errors during data transmission. Error control is implemented at the data link layer using automatic repeat request (ARQ) protocols like stop-and-wait and sliding window. Stop-and-wait involves transmitting a single frame and waiting for an acknowledgment before sending the next frame. Sliding window protocols allow multiple unacknowledged frames to be transmitted by using frame numbers and acknowledging receipt of frames. These protocols detect errors when frames are received out of sequence and trigger retransmission of lost frames.

The medium access sublayerLal Bahadur Gehlot

The document discusses the Medium Access Control (MAC) sublayer of the data link layer and various protocols for determining which device can access a shared communication channel. It focuses on static and dynamic channel allocation problems in local area networks (LANs) and wireless networks. Static allocation wastes bandwidth by assigning each user a fixed portion of the channel even when they are not transmitting. Dynamic protocols like ALOHA and carrier sense multiple access (CSMA) aim to improve channel utilization by allowing users to transmit only when the channel is idle.

Computer Network - Network LayerManoj Kumar

The network layer is responsible for delivering packets from source to destination. It must know the topology of the subnet and choose appropriate paths. When sources and destinations are in different networks, the network layer must deal with these differences. The network layer uses logical addressing that is independent of the underlying physical network. Routing ensures packets are delivered through routers and switches from source to destination across interconnected networks.

Network Layer design Issues.pptxAcad

The network layer provides two main services: connectionless and connection-oriented. Connectionless service routes packets independently through routers using destination addresses and routing tables. Connection-oriented service establishes a virtual circuit between source and destination, routing all related traffic along the pre-determined path. The document also discusses store-and-forward packet switching, where packets are stored until fully received before being forwarded, and services provided to the transport layer like uniform addressing.

Chapter 4 data link layerNaiyan Noor

Flow Controlselvakumar_b1985

Flow control specifies how much data a sender can transmit before receiving permission to continue. There are two main types of flow control: stop-and-wait and sliding window. Stop-and-wait allows transmission of one frame at a time, while sliding window allows transmitting multiple frames before needing acknowledgement. Sliding window flow control uses variables like window size, last ACK received, and last frame sent to determine how transmission proceeds. It provides more efficiency than stop-and-wait. Automatic repeat request (ARQ) handles retransmission of lost or damaged frames through timeouts, negative acknowledgements, or cumulative acknowledgements depending on the specific ARQ protocol used.

HDLCNewcovenant Muro

HDLC is a bit-oriented protocol defined by ISO for point-to-point and multipoint communication over data links. It supports full-duplex communication and provides reliability, efficiency and flexibility. HDLC defines three types of stations - primary, secondary and combined. It uses three frame types - unnumbered, information and supervisory frames. HDLC also specifies three data transfer modes - normal response mode, asynchronous response mode and asynchronous balanced mode. [/SUMMARY]

data-link layer protocols BE Smârt

This document provides an overview of data link control (DLC) and data link layer protocols. It discusses the key functions of DLC including framing, flow control, and error control. Framing involves encapsulating data frames with header information like source and destination addresses. Flow control manages the flow of data between nodes while error control handles detecting and correcting errors. Common data link layer protocols described include simple protocol, stop-and-wait protocol, and High-Level Data Link Control (HDLC). HDLC is a bit-oriented protocol that supports full-duplex communication over both point-to-point and multipoint links. It uses three types of frames: unnumbered, information, and supervisory frames.

TCP and UDP Ramesh Giri

TCP and UDP are transport layer protocols used for data transfer in the OSI model. TCP is connection-oriented, requiring a three-way handshake to establish a connection that maintains data integrity. It guarantees data will reach its destination without duplication but is slower than UDP. UDP is connectionless and used for applications requiring fast transmission like video calls, but does not ensure packet delivery and order. Both protocols add headers to packets with TCP focused on reliability and UDP on speed.

TCP & UDP ( Transmission Control Protocol and User Datagram Protocol)Kruti Niranjan

This document provides information about the Transport Layer protocols TCP and UDP. It describes: 1) TCP is a connection-oriented protocol that provides reliable, in-order delivery of data through features like flow control, error control, and congestion control. UDP is a connectionless protocol that does not guarantee delivery or order of packets. 2) The TCP header contains fields for source/destination ports, sequence numbers, acknowledgement numbers, flags, window size, checksum, and options. The UDP header contains fields for source/destination ports, length, and checksum. 3) The main differences between TCP and UDP are that TCP is connection-oriented, provides error control and flow control, and supports full duplex communication

Congestion on computer networkDisi Dc

This document presents an overview of computer network congestion and congestion control techniques. It defines congestion as occurring when too many packets are present in a network link, causing queues to overflow and packets to drop. It then discusses factors that can cause congestion as well as the costs. It outlines open-loop and closed-loop congestion control approaches. Specific algorithms covered include leaky bucket, token bucket, choke packets, hop-by-hop choke packets, and load shedding. The document concludes by noting the importance of efficient congestion control techniques with room for improvement.

Flow control & error controlManishTadhiyal

User datagram protocol (udp)Ramola Dhande

UDP is a connectionless transport layer protocol that runs over IP. It provides an unreliable best-effort service where packets may be lost, delivered out of order, or duplicated. UDP has a small 8-byte header and is lightweight, with no connection establishment or guarantee of delivery. This makes it fast and low overhead, suitable for real-time applications like streaming media where resending lost packets would cause delay.

Nigga.pdfpdegree76

Elementary data link protocols are designed to perform framing, error control, and flow control. Framing divides bitstreams into frames of a few hundred to a few thousand bytes. The unrestricted simplex protocol allows one-way transmission with infinite buffers and no faults or lost frames. Stop-and-wait protocols provide one-way transmission and flow control for error-free channels, acknowledging each frame before sending the next. Noisy channel protocols use techniques like error detection and retransmission to minimize errors over noisy channels.

DataLinkControl.pptMaddalaSeshu

This document discusses various data link layer protocols. It begins by describing the services provided by the data link layer, including framing, error control, and flow control. It then discusses different types of framing such as fixed-size and variable-size. The document also covers different protocols for handling flow control and error control, including stop-and-wait, go-back-N ARQ, and selective repeat ARQ. It analyzes the performance of these protocols on both noiseless and noisy channels.

Protocol testing is a method to check communication protocols by examining the structure of packets sent over a network. It involves using tools like protocol analyzers and simulators to test devices under test like routers and switches. The primary goals are to check if protocols like EIGRP and OSPF are working as specified. Protocol testing can examine functionality, performance, interoperability and more. It verifies that packets are received correctly and measures latency and bandwidth. Tools like Wireshark, Scapy and IxNetworks are used to craft packets and analyze network traffic during protocol testing.

WLAN:VPN Security@zenafaris91

VPN (virtual private network) allows users to connect securely over a public network like the internet. It uses encryption and authentication to provide a secure connection through an otherwise insecure network. The main benefits of VPNs are reduced costs compared to dedicated private networks using leased lines or dial-up. VPNs work by encapsulating packets inside packets of another protocol, called "tunneling", to create and maintain a virtual private circuit between two endpoints.
