The design of this “BGP” router is based on an internal radix tree structure containing the routing database. Routes are indexed in the tree based on the bit pattern of their subnet, and route lookup walks the tree to find the most specific route node corresponding to the requested destination address. The router itself is based on Racket’s built-in I/O multiplexing to automatically manage I/O between multiple sockets.
There were three major parts to the post-milestone effort. We implemented the “being mean to peers that don’t pay you” rules with fairly little effort, and we also implemented route aggregation and disaggregation with minimal changes to the existing radix tree backend and some additional router logic. Finally, (the most time-consuming part) we fixed bugs in the existing implementation that we found when evaluating against the full test suite. Besides bugs, just adding aggregation and meanness functionality was all that was necessary to pass all the tests.

For the milestone submission, we included some basic internal unit tests but there isn’t a lot of code coverage on those yet. We also ran the simulator milestone tests against the current router implementation and both milestone tests are passing.
For the final submission, we included some more basic internal unit tests where necessary when implementing new features. We also ran the provided simulator (the newest version provided) against the router testing for all tests. Currently, all provided tests pass when testing on the CCIS login server.
