Tcp state transition diagram. Closed is fictional because it represents the state when there is no tcb and therefore no connection.

Tcp socket state diagram. The following diagram illustrates the possible states for a tcp connection and how the states transition based on various events from either the network or from the local tcp sockets application. The server sends the client a packet with a fin bit set. The first thing to note in this diagram is that a subset of the state transitions is typical we ve marked the normal client transitions with a darker solid arrow and the normal server transitions with a darker dashed arrow.

At this point the server is in fin wait 1 state. Principle of establishing a tcp connection the state diagram. The socket is named bound to a local address and port and is ready to accept incoming connection requests.

Tcp state transition diagram. The socket can be named explicitly with bind or implicitly with conenct. Socket returned an unnamed socket an unnamed socket is one that is not bound to a local address and port.

Here are the steps of connecting and libration of a tcp connection. The client application opens a connection to the server by sending a tcp segment which only the header is present no data. A tcp connection progresses through a series of states during its lifetime.

This header contains a flag syn stands for synchronize and the tcp port number the server application.

Fin wait 2 seems to occur when the server has an active connection with a client and wants to shut down the tcp connection probably in response to a normal application layer exit.
