VPP (Vector Packet Processing) is the opensource software aiming to very fast data-processing and its part of the umbrella project known as FD.io
This talk describes how to design and integrate a new L4 protocol in the existing VPP (Vector Packet Processing) framework. We will use as an example the novel SCTP implementation which has been developed (and now maintained) by the SUSE employee Marco Varlese.
We will go through the concept of the transport-layer and how the upper-layers (session and application) in VPP interact with the transport-layer in order to fully establish an SCTP connection, how to send and receive data and eventually terminate a connection.
We will also showcase the new SCTP implementation and the diverse levels of debugging offered.
