TCP provides reliable transmission of data in an IP environment. Corresponding TCP transport layer (layer 4) of the OSI reference model. Among the services TCP provides are stream data transfer, reliability, efficient flow control, dual full cooperation and multiplexing. With stream data transfer, TCP delivers an unstructured stream of bytes identified by serial numbers.
This service benefits applications because they have no data to cover the blocks before handing it to TCP. Instead, TCP groups bytes into segments and passes them to IP for delivery. TCP offers reliability by providing connection-oriented, providing end-to-end reliable packet through an Internetwork.
It does this by sequencing bytes sent acquaintance with a number indicating the next byte source destination expects to receive. Bytes not acknowledged within a certain period is retransmitted. Reliability mechanism of TCP allows devices to deal with lost, delayed, duplicate or incorrect packages.
A timeout mechanism allows the equipment lost packets and retransmission request to discover. TCP offers efficient flow control, which means that when sending acknowledgments back to the source, receiving TCP process indicates the highest sequence number can receive without overflowing its internal buffers.
full duplex operation means that TCP processes can both send and receive at the same time. Finally, TCP multiplexing means that the multiple simultaneous high-level talks may be multiplexed over a single connection.
