The host stack can be used by both internal and external, with respect to vpp, applications. For debugging and performance testing two pairs of such apps have been developed.
Builtin Echo Server/Client
These applications leverage the internal C apis to establish connections, shared memory fifos for sending and callback functions for receiving data. For simple debugging of the stack, start two debug images and:
On vpp1 (the server), from the cli do:
# test echo server uri <transport>://vpp1_ip/port
and on vpp2 (the client):
# test echo client uri <transport>://vpp1_ip/port
Half-Duplex single connection throughput
For connection oriented transport protocols like TCP processing is pinned to a core so for testing purposes running vpp with one core (main thread) is enough.
vpp1# test echo server uri <transport>://vpp1_ip/port fifo-size 4096 no-echo vpp2# test echo client uri <transport>://vpp1_ip/port fifo-size 4096 test-timeout 100 no-return mbytes 10000
The no-echo and no-return options configure the server and the client for half-duplex operation, fifo-size sets configures the client and server to use 4MB rx and tx fifos and mbytes on the client asks for a 10GB transfer.
External Echo Server/Client
These applications leverage the binary api for establishing connections and shared memory fifos for data exchanges.
