I am confused about sequence & acknowledgement numbers of TcpIp. Here is the detail why.

1: I have two server connections and two client connections.

Client make connections at remote addresses. Server accepts two connections separately not those which are for clients.

So Is each client & server will manage separate unique sequence & acknowledgement number. e.g Client 1 seq=5 Client 2 sequence= 10 Server 1 sequence=17 & Server 2 sequence number =25 ?

  • You are confusing TCP with applications. TCP doesn't have clients and servers, it has connections between peers. Applications, which are off-topic here, have clients and servers.

Sequence numbers are negotiated and incremented on a per-socket basis. If there are two TCP sessions running between two hosts the TCP sequence numbers are completely independent.
