How to implement the service interface topology?

[qiansheng91]

Hi guys:

I want to implement the service interface topology by using OT, For example:

1. Span[/a](kind: server) ----> Span[b](kind: internal)
2. Span[b](kind: internal) ----> Span[c](kind: client)
3. Span[c](kind: client) ----> Span[/d](kind: server)

The Topology should look like this:

/a  ---->  /d

And I think that the fastest way I've found to do this is to pass the upstream service name to the downstream. Is there any suggestion for me to implement this?
