BIRD Journey to Threads. Chapter 3½: Route server performance

21.2.

All the work on multithreading shall be justified by performance improvements. This chapter tries to compare times reached by version 3.0-alpha0 and 2.0.8, showing some data and thinking about 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 run in multiple threads in parallel.

BIRD Journey to Threads. Chapter 3: Parallel execution and message passing.

9.2.

Parallel execution in BIRD uses an underlying mechanism of dedicated IO loops and hierarchical locks. The original event scheduling module has been converted to do message passing in multithreaded environment. These mechanisms are crucial for understanding what happens inside BIRD and how its internal API changes.

BIRD Journey to Threads. Chapter 2: Asynchronous route export

14.6.

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.

BIRD Journey to Threads. Chapter 1: The Route and its Attributes

23.3.

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 Journey to Threads. Chapter 0: The Reason Why

15.3.

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.
