Transmission control protocol operates in various states throughout the life cycle of a connection.
Understanding these states is crucial for analyzing network traffic and troubleshooting connectivity
issues.
Now let's delve deeper into the TCP state.
The first lesson in this state, The system is waiting for connection requests from a remote host,
and it typically occurs on servers that are ready to accept incoming connection.
Synchronize send.
After the client initiates a connection request by sending synchronized packet, it enters the synchronized
send state and the client waits for a response from the server in that state.
Sin received.
When the server receives this packet, it sends back the synchronized acknowledge packet to the clients
request.
So the server then enters the synchronized received states waiting for the final knowledge from the
client established.
Once a client receives a synchronized acknowledged packet, it sends the acknowledged packet to the
server and indicating that the connection is established.
Both the client and server enter the established state loving bidirectional communication.
Finweight won when one side of the connection wishes to terminate the session, it sends a thin packet
to initiate the closure.
The side sending the thin packet enters the finweight one state waiting for acknowledgement from the
other side.
Thin weight, too.
After sending the thin packet, the side initiating the termination enters the thin weight two state.
It waits for a thin packet from the remote host to confirm the termination request.
Claws weight.
When one side receives a fin packet from the other side, it enters the claws.
Wait state.
The side acknowledges the.
Termination request and waits for the own application to close the connection.
Closing in the closing state.
A host has sent thin packet and is in the process of closing the connection.
It waits for acknowledgement from the remote host to complete the closure.
Last acknowledgement, after receiving a thin packet and sending its acknowledgement, the host enters
the last acknowledgement state.
It waits for a final acknowledgement from the remote host to confirm the termination.
Time wait.
In the time wait state, a host has sent a termination request and is waiting to ensure that the remote
host receives the request.
This state has helps to prevent a premature connection termination due to the delayed packets.
And lastly clause.
The clause state does not represent any active state but indicates a closed connection.
Understanding these TCP states is crucial for network administrators and analysts when troubleshooting
network connectivity issues or analyzing network traffic using tools like Wireshark.
By examining this state transitions and associated packets, they can identify potential problems and
ensure smooth communication between hosts.
TCP reliability sequencing and error recovery mechanisms make it ideal for connection oriented sessions
where data integrity is critical.
However, for applications where speed is paramount and real time communication is more important than
reliability protocols like UDP user datagram protocol may be more suitable.
