Dear All, The example application hs_apps/proxy.c ( https://github.com/FDio/vpp/blob/master/src/plugins/hs_apps/proxy.c ) seems to achieve the functionality of TCP proxy using VPP host stack.
1. It uses Session Layer API with FIFO. My understanding is that it includes 2 packet memcpy for all the TCP data packets (One from vlib_buffer to FIFO, again from FIFO to vlib_buffer). Any solution to avoid this and modify the same buffer between connections? Assuming it is okay to compromise on packet reordering or TCP segment overlap functionality. 1.1 Since the proxy runs in same VPP process, shared memory is not needed. Also any documentation on Hoststack's Binary API? 2. If it is not possible to avoid FIFO in shared memory, is there any limit on the number of connections because of the linux fd?
