Route export is a core algorithm of BIRD. This chapter covers how we are making this procedure multithreaded. Desired outcomes are mostly lower latency of route import, flap dampening and also faster route processing in large configurations with lots of export from one table.
Data structures used by BIRD have to be changed in order to allow multithreading safely. This chapter covers necessary changes of them. BIRD is a fast, robust and memory-efficient routing daemon designed and implemented at the end of 20th century. We’re doing a significant amount of BIRD’s internal structure changes to make it possible to run in multiple threads in parallel.
BIRD is a fast, robust and memory-efficient routing daemon designed and implemented at the end of 20th century. Its concept of multiple routing tables with pipes between them, as well as a procedural filtering language, has been unique for a long time and is still one of main reasons why people use BIRD for big loads of routing data.
