OpenBGPD 9.0 & bgp-perf release!

OpenBGPD 9.0 has been released, which will be arriving in the OpenBGPD directory of your local OpenBSD mirror soon.

Additionally, a new software package named "bgp-perf" has been made available. This package contains two BGP stress-test utilities: bgp-blaster and bgp-canary. The bgp-blaster tool can load mrtdump files into a table and emulates many peers using that table in an efficient way. The bgp-canary tool sends special UPDATE messages to the system under test and measures the latency through the BGP node.

This OpenBGPD release includes the following changes to the previous release:

• Rewrite the Adj-RIB-Out handling to be more memory efficent and faster. For large IXP route server deployments a reduction in memory usage of more than 50% should be feasible.

• Process UPDATE messages in two phases: first update Adj-RIB-In, Loc-RIB, and FIB, then process all the Adj-RIB-Out tables This significantly reduces the latency since updating all the Adj-RIB-Out tables could take a fair amount of time.

• Introduce CH hash tables - a scalable hash map implementation that boosts performance through improved cache locality.

• Introduce new metrics that track the amount of time spent in various parts of the main event loop of the route decision engine.

• Fix various non-criticial things uncovered by Coverity scanner.

  
  

OpenBGPD-portable is known to compile and run on FreeBSD and the Linux distributions Alpine, Debian, Fedora, RHEL/CentOS and Ubuntu. It is our hope that packagers take interest and help adapt OpenBGPD-portable to more distributions. We welcome feedback and improvements from the broader community. Thanks to all of the contributors who helped make this release possible.
