Service Function Chaining Implementation

[binhfdv]

Sorry if my question is trivial.
For my research, I have to program the SFC for requests from a UE (like in Exercise 8). I am stuck on how to start the programming for the experiment.

If anyone could give me a piece of instructions on where to begin, really appreciate it!

Currently, I can connect my k8s service pods to switch in the mininet. I can "curl" the service from my UE as well.
curl 10.96.10.10:5000 --interface uesimtun0

Now I am stuck on how to create a SRv6 routing table to route the traffic from UE to Service 1 then to Service 2
UE -> S1 -> S2
and
UE -> S1 -> S2 -> UE

Thank you!
