Protocol Working at Host to Host (Transport) layer tutorials

 

TCP [Transmission Control Protocol]

 

UDP [User Datagram Protocol]

 

TCP takes large blocks of information from an application and breaks them into segment. It numbers and sequences each segment so that the destination TCP can put those segments back into the order. After these segments are sent, it waits for an acknowledgement. It resends anything that is not received.

 

It is connection oriented

 

It is reliable & accurate

 

As it checks for error, it is complicated and costly in terms of network overhead.

 

UDP does not sequence the segment and does not care in which order the segments arrive at the destination. After it sends the segment it forgets about it and do not acknowledge it.

 

 

Because does not contact the destination before delivering information to it, it is considered as connectionless protocol.

 

 

It is fast but unreliable.

 

It is simple and does not increase network overhead.

 

 

Port Numbers

  • Both TCP and UDP can send data from multiple upper-layer applications at the same time. Port or Socket numbers keep track of different conversations crossing the network at any given time. Well-known port numbers are controlled by the IANA, the Internet Assigned Numbers Authority (IANA) is responsible for assigning the values used for TCP/IP protocols and ports. Application that do not use well-known port numbers have them randomly assigned for specific range. This random port is referred to as an ephemeral port.

 

PORT Numbers are as follows

  • Numbers 1 to 1024 are considered Well-known ports

  • Numbers 1025 to 49151 are registered

  • Number 49152 to 65535 are private vendor assigned and are dynamic.
