Presentation Transcript

  1. Project 1 • Distance-vector Routing implementation • Only need to implement a class called RIPRouter • Spec based on RIP (Routing Information Protocol) • Hop-count as distance metric • Implicit Withdrawal • Split Horizon (for Poison Reverse) • 100 – max hop-count

  2. Key Implementation Pointers • Route establishment • Centered around distance-vector updates • How to process an update. • When to send new updates? (Penalty if you send too many) • What should the update look like? • Packet Forwarding • Select the next hop based on forwarding table. • Freedom to construct appropriate data structure to store routing information.

  3. Provided Code • Simulator that can link up hosts and your RIPRouters in different topologies and forward packets. • Refer to the simulator guide • A visualizer (NetVis) where you can see the topology and packets.

  4. Extra Credits (maximum 2 out of 3) • #Routing Updates • Link Weights and SmartDV • Can you be smarter about processing DV updates? • Link State implementation and analysis

  5. Logistics • GSIs: Kaifei, Radhika and Gautam • Additional OH for help with the project – will be announced on Piazza • Due October 10, 2013 at midnight. • Submit through instructional machines ‘project1’.
