TCP and SCTP

TCP (Transmission Control Protocol) and SCTP (Stream Control Transmission Protocol) are both transport layer protocols used in computer networks to establish reliable connections and transfer data between devices.

TCP:

Connection-oriented: Before data transfer, a connection must be established between the sender and receiver.
Reliable: It ensures data is delivered correctly by using acknowledgements, retransmission of lost packets, and error-checking.
Ordered delivery: Data is sent in a specific order, and the receiver reassembles it in the same order.
Congestion control: TCP adjusts the rate of data transmission based on network conditions to prevent congestion.

 

SCTP:

Connection-oriented: Like TCP, it establishes a connection between the sender and receiver before data transfer.
Reliable: SCTP also ensures correct data delivery through acknowledgements, retransmission, and error-checking.
Multi-streaming: It can send multiple streams of data simultaneously, allowing different streams to be processed independently.
Multi-homing: SCTP supports multiple IP addresses for a single connection, providing redundancy and fault tolerance.

 

In summary, both TCP and SCTP are used for reliable data transmission, but SCTP has some additional features like multi-streaming and multi-homing that make it more versatile for certain applications.
