Eg: In the packet graph mentioned below, if I decide to add packet validation in runtime Packet processing graph from ethernet-input –> ip4-input changed to ethernet-input –> packet-validatation -> ip4-input Yes, you can add in a graph node: https://fd.io/docs/vpp/master/whatisvpp/extensible.html https://fdio-vpp.readthedocs.io/en/latest/gettingstarted/developers/add_plugin.html https://fdio-vpp.readthedocs.io/en/latest/gettingstarted/developers/vlib.html * Also can we have core affinity for nodes. Say I have node-1 running in core-2 and node-2 running in core-3 etc … Please check the vlib functionality under (Handing off buffers between threads) is what u looking for. https://fdio-vpp.readthedocs.io/en/latest/gettingstarted/developers/vlib.html#handing-off-buffers-between-threads Thanks! -- Balaji Request for some pointers in this regard. Thanks in advance, Prashanth
