Proactive Routing Path Updates Using Peacock in SDN
- 1. Research Presentation PROACTIVE-ROUTING PATH UPDATE USING PEACOCK IN SOFTWARE DEFINED NETWORKING (SDN)
- 2. Presented By, MD Shibli Mollah FARIHA Haider MD. RAZU
- 3. What is SDN and Why? CENTRALIZATION AND AUTOMATIC MANAGEMENT OF NETWORKING DEVICES • SDDC • SCALIBILITY • COST • Dependency on PHYSICAL DEVICES • VIRTUALIZATION • IMPLEMENT NEW IDEAS
- 4. What is SDN and Why? • Programming Based • Faster and Automatic • Central Controller(BGP, EIGRP, ARP, STP, OSPF) • Change Dynamically • Separation of CONTROL Plane & DATA Plane • Productivity, Security.
- 7. Network Update in SDN Network Update Topology Update Policy Update Route Update Proactive-Routing Protocol (Table Driven) Reactive-Routing Protocol (On Demand) Hybrid-Routing Protocol
- 8. OpenFlow OpenFlow (OF) is considered as one of the first software-defined networking standards. It originally defined the communication protocol in SDN environments that enables the SDN Controller to interact directly with the forwarding plane of network devices such as switches and routers, both physical and virtual.
- 9. Pro-active Routing Protocol Pro-active routing protocols require each node to maintain up-to-date routing information to every other node in the network. Controller programs the switches proactively.
- 10. Advantages and Disadvantages of Pro-active Advantages: • Lower route setup latency • Zero additional flow setup time • Loss of control connection does not disrupt traffic • essentially requires aggregated rules • Controller pre-populates flow table in switch. Disadvantages: • High routing overhead (periodic distribution of routing information) • State routing information in highly dynamic topologies
- 11. WayUp Routing Algorithm 1 Input: old policy π1,Waypoint_node Si , threshold θ 2 new policy π2 2 update switches of π2 which are not in π1 3 update switches of π>wp1 with backward Rules in π<wp2 4 update remaining switches of π<wp2 5 wait θ 6 update switches of π>wp Π1 solid line(Old polocy). Π2 dashed line(New polocy). S3 waypoint node.

- 13. Proactive- routing algorithm Peacock We are working on Peacock algorithm to implement pro-active routing path update. Focus area: Update duration (Time Complexity)
- 14. Software Defined Networking(SDN) Implementation Process ❑ Mininet emulator. ❑ Ryu SDN controller. ❑ OpenFlow protocol supported switch. ❑ Wireshark.
- 15. Ryu SDN controller ❑ Controller is a brain of SDN architecture. Several SDN controller are available like OpenDayLight, Onos, Ryu, Pox, Nox etc. ❑ We are using Ryu SDN controller for our research.
- 16. Wireshark ❖ Wireshark is a network traffic analyzer. ❖ Demo of openFlow packets captured by wireshark.
