Re: [vpp-dev] #vpp loadbalancer #vpp

Hello, The VPP LB is pretty much an implementation of Maglev (https://ai.google/research/pubs/pub44824). Maglev is the consistent hashing algorithm used to generate the ’new_flow_table’. That table is used when a packet for a flow that is not known by the LB is forwarded. When that happens, th

Re: [vpp-dev] question about load balance

Hello, You will not be able to get an exact match on 1/3 - 2/3 traffic sharing since 3 is not a power of two. If you want to get something closer, you may try to increase the values to get a better approximation. For instance, 43 and 85 have a sum of 128 with 43/128 = 0.3359375, which is close

Hello Choonho, MagLev is a layer 4 load-balancer. It load balances TCP connexions to a set of targets. This is done by simply forwarding packets on a per-5-tuple basis with a flow table to remember decisions. Since the destination address of packets is not modified, a tunnel is necessary. HAPro

You basically have two options: 1. Teach your routing protocol daemon to directly talk to VPP for configuring the FIB. 2. Do not modify the routing daemon and let VPP map routes written in the kernel. For 1, you will need the router plugin, but for packet punting only. For 2., you will need bot

Hello Jon, No strong opinion on my side, but I'd just like to notice that there might be cases where multiple interfaces, in linux, have the same name, if they are in different network namespaces. VPP could literally control the back-end of thousands of containers' interfaces, all called eth0.
