The Transmission Control Protocol (TCP) isone of the core protocols of the Internet protocol

suite. TCP is one of the two original components

of the suite, complementing the Internet

Protocol (IP), and therefore the entire suite is

commonly referred to as TCP/IP.

TCP/IP

A full suite of protocols spanning layers

2 (Datalink) through 7 (Application)

Informally named for Transmission

Control Protocol (Layer 4 - Transport)and Internet Protocol (Layer 3 -

Network), it is comprised of many

protocols

0 16 32

Sequence Number of First Data Octet (32)

Next Expected Ack Number (32)Window (16)

Checksum (16)Ofst(4) Rsvd(6) Flags(6)

Options + Pad (varies) Payload (varies)Urgent Data Pointer (16)

TCP Header Fields

Explained Ofst - Data offset/length of header in 32-bit words

Rsvd - Reserved

Flags

Urgent Data Pointer Significant (URG)

Ack Field Significant (ACK) Reset Connection (RST)

Push Function (PSH) prompt forwarding

Synchronize Sequence Numbers (SYN) seq # is initial

No More Data (FIN)

Window - number of octets sender will accept

Option - one octet OR one octet type + one octet length + n

octets option information

Conclusion

TCP is the protocol used by major Internet

applications such as the World WideWeb, email, remote administration and filetransfer because of these application TCP/IP isvery useful and important protocol. In future theuse of internet is increases with that TCP/IPprotocol become much more important.
