The SRv6 “micro segment” (uSID for short) solution is an extension to the SRv6 Network Programming model. It allows expressing SRv6 segments with a very compact and efficient representation, for example using two bytes for uSID instead of using a normal IPv6 address (16 bytes) for a regular SRv6 segment.
The demo runs on a mininet topology made up of eight P4 enabled switches (based on bmv2 P4 software implementation) and two hosts that represent Site A and Site B. The source code and the detailed instruction to run the demo are reported below.
