Authentication (AuthN, 認証) and authorization (AuthZ, 承認) are important pieces in system security. In one word, AuthN verifies the identity of the requester, and AuthZ decides whether a specific operation is allowed.
Service invocation is tricky. The protocol itself seems to be super simple: we call a function, and it returns. But the problem is, when the function is on another machine, how we know the state of that machine / the whole system. The developers of the caller do not want to care, so we protocol designers should care for them. But trying to make everyone happy is so tough here.
There is always a need for service discovery and load balancing, but no universal solution. Sometimes naive ways may satisfy most needs.
I find that some terms are confusing.
TL; DR: Reflection should be used for encoding or serilization.
