2017

Replaced the python ipaddress module in my BGP program with my own very minimal one to reduce memory usage. Replaced some empty sets/lists that may not ever have data with "None" by default as empty data structures are quite memory heavy when you have millions of them. Also updated a couple of heavily used classes to use slots (explicitly stating the attributes) rather than leaving it open ended (and using more memory).

Started looking at adding a command interface to allow updating filters and receiving external measurements or metadata about how we should be routing traffic. The current event loop around I/O doesn't really support this (and has other issues about deadlocking with exabgp) so needed to be rewritten. All exabgp reading and writing now happens in the same place, and in a different thread to the command interface and route management.
