Using the Simple Forwarding Application
The OpenDaylight Controller includes an application called Simple Forwarding that lets you use
the basic services for making forwarding decisions and install flows across all devices on the
Openflow network. This application discovers the presence of a host via ARP message and
installs dest-only /32 entries across all switches in the network, with the corresponding output
ports toward the host.

1. With OpenDaylight Controller and Mininet running as described in previous sections,
log into the web interface.

2. Drag and drop devices to organize the topology into its logical arrangement, then save
the configuration.

3. Click the Add Gateway IP Address button (shown above) and add the IP and subnet
of 10.0.0.254/8

4 Confirm that hosts are now reachable from one another. On the console where Mininet
is running, have one host ping another.
mininet> h1 ping h7

Las ACLs son listas de control de acceso que determinan si un paquete debe ser retransmitido o descartado. Existen ACLs numeradas y nombradas. Las numeradas se identifican por un número y no permiten eliminar líneas individuales, mientras que las nombradas se identifican por un nombre y sí permiten eliminar líneas individuales. Las ACLs se asignan a interfaces y se procesan después de aplicar las rutas para paquetes entrantes o salientes.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.

SDN Training - Open daylight installation + example with mininet

1. OpenDaylight, FloodLight stallation, and Example with Mininet OpenDaylight-Installation + Example with Mininet https://wiki.opendaylight.org/view/OpenDaylight_Controller:Installation Download VM with both OpenDayLight, FloodLight and Mininet http://yuba.stanford.edu/~srini/tutorial/SDN_tutorial_VM_64bit.ova user: ubuntu password: ubuntu Edit /etc/bash.bashrc Add the following line: PATH=$PATH:/var/lib/gems/1.8/gems/trema-0.3.19/objects/openvswitch/bin Mininet Sample Virtual Network Start Minit with this topology su sudo mn --topo=tree,3 --mac --switch=ovsk --controller=remote,ip=a.b.c.d where IP is the address of your VM (Remote OpenDayLight Controller VM/Server) OpenDaylight Example Start OpenDayLight cd opendaylight/opendaylight/distribution/opendaylight/target/distribution.opendaylightosgipackage/opendaylight sudo ./run.sh

2. Open OpenDayLight GUI localhost:8080 user: admin password: admin Using the Simple Forwarding Application The OpenDaylight Controller includes an application called Simple Forwarding that lets you use the basic services for making forwarding decisions and install flows across all devices on the Openflow network. This application discovers the presence of a host via ARP message and installs dest-only /32 entries across all switches in the network, with the corresponding output ports toward the host.

3. 1. With OpenDaylight Controller and Mininet running as described in previous sections, log into the web interface.

4. 2. Drag and drop devices to organize the topology into its logical arrangement, then save the configuration.

5. 3. Click the Add Gateway IP Address button (shown above) and add the IP and subnet of 10.0.0.254/8 4 Confirm that hosts are now reachable from one another. On the console where Mininet is running, have one host ping another. mininet> h1 ping h7 PING 10.0.0.7 (10.0.0.7) 56(84) bytes of data. 64 bytes from 10.0.0.7: icmp_req=1 ttl=64 time=1.52 ms 64 bytes from 10.0.0.7: icmp_req=2 ttl=64 time=0.054 ms 64 bytes from 10.0.0.7: icmp_req=3 ttl=64 time=0.060 ms 64 bytes from 10.0.0.7: icmp_req=4 ttl=64 time=0.052 ms --- 10.0.0.7 ping statistics --4 packets transmitted, 4 received, 0% packet loss, time 2999ms rtt min/avg/max/mdev = 0.052/0.422/1.523/0.635 ms mininet>

6. 5. Click the Troubleshooting tab and then load the Flow Details for one of the switches.

7. 6. View the Port Details.

8. FloodLight Example Start FloodLight cd floodlight ./floodlight.sh Note: use the same previous Mininet Virtual network sudo mn --topo=tree,3 --mac --switch=ovsk --controller=remote,ip=a.b.c.d Open OpenDayLight GUI localhost:8080/ui/index.html

10. Sample FloodLight Java Application Avior is an application built outside of floodlight that gives network administrators a graphical user interface to support their needs. Avior eliminates dependency on using python scripts or viewing the restAPI in order to monitor or manipulate the network. Download from: http://openflow.marist.edu/avior Enter IP of the remote controller (i.e. machine running FloodLight).

11. Controller Information Switch Information

12. Hosts/Servers Information Flow Manager Sample Application

13. Firewall Sample Application Also available, a QoS Java Application: https://github.com/wallnerryan/floodlight-qos-beta
