re: vs cumulus vs snabb vs OVS vs OpenNSL


Gleaned this thread on nanog mailer archive [1] mentioning :slight_smile:

Not a "thought leader", but I thought I respond with some data
points, hopefully relevant to the thread’s subject.

Note that most of them focus on data plane functionality, performance
and technology level comparison:

  - IPv4 routing (large FIB) at Terabit speed, a video clip (low-budget)
    showing what difference modern Xeon processors (Skylake) can make to
    SW data plane if coupled with something super-fast, produced by LF project for Xeon Skylake launch on 11th July 2017 (a year
    ago). [2]

  - SW data plane benchmarking, technical paper [3][4].

  - Test and performance report for last release [5].

  - Continuous trending of vpp master branch [6].

And although network control plane is not covered (e.g. BGP), many data
plane hooks required are there incl. large FIBs, VRFs, hierarchical FIB
for IP fast convergence, multicast, etc.
