Project Overview

Project Name: IPv6 Global Routing
Student: Shashwat Patni
Mentors: Tommaso Pecorella and Manoj Kumar Rana

Project Goals: The aim of this project is to extend the functionality of GlobalRouting to Ipv6, while maintaining minimal code duplication. Global Routing is based on the OSPFv2 routing protocol and uses the Djikstra Shortest path algorithm to compute paths for a single area network configuration. The problem is that GlobalRouting doesn't work for IPv6, and that's a huge limitation. The goal of the project is to fix that limitation. Deliverables include a working implementation of Ipv6GlobalRouting which handles different Address Types in Ipv6, while also maintaining Minimal Code Duplication.

Milestones

These are the current Macro Goals for the project:

Note: For each phase , the plan is to work in the following order of classes: Interface Classes -> Setup Classes -> Route Computation Classes

Phase 1:

Port existing Ipv4GlobalRouting to generic GlobalRouting
Generalize ipv4-global-routing-test-suite and global-route-manager-impl-test-suite
Create tests and verify GlobalRouting works for Ipv4 after templatization
Design Tests for Ipv6 Specific Properties for GlobalRouting
Introduce Type Aliases for IP classes

Phase 2:

Phase 3:

Duration: 8 May - 1 June

Working on the patch requirement !2434 :Adds the Print Route-Path Functionality to GlobalRouting.
A Design Document has been created to allow for discussions and evolving the design for the project

Duration: 2 June - 9 June

This week we

Designed Tests For IPv4 GlobalRouting Specifically tests for the GlobalRouteManagerImpl Class
Created a draft MR For the tests !2471 for review
There was a discussion on if Link Local Addresses or Global Unicast Addresses Should be used as Next Hops in the RoutingTable Entries.

Duration: 10 June - 17 June

This Week the plan is to:

Currently there are two MRs Open for review !2471 and !2434

Duration: 18 June - 23 June

This Week we did the following:

Finished Templatizing ipv4-global-routing classes to generic global-routing classes. The CI and tests pass . The latest version of the code is available at GSoC25
While Working on tests we found a few bugs in the existing implementation related to Equal Cost Multipath Topologies. We worked on resolving them
We discussed if a templateless approach is possible . Templates are bad because they create a learning curve for the model and the compiler errors may be cryptic for new users.A hybrid version with minimal templatization would be better.
