Discovery Usecase

Post by rakshan »

Hello,
I have a question on Discovery.
Suppose a network has multiple client and servers. A client wants to establish connection to the serverA. However, that serverA is already having a session with other clientB.
Theory says servers can have multiple sessions with multiple clients. I am curious if there is any approach where in, when the client tries to reach to serverA, it gets a response saying its busy and not available(considering only 1 session could be established by a client and server).

REST API could be one of the approaches with sessionless data transfer. Or any other approach you suggest?

Regards,
Rakshan
