Configuring Tcp - Cisco ASR 1000 Series Configuration Manual

Configuring TCP

TCP is a protocol that specifies the format of data and acknowledgments used in data transfer. TCP is a
connection-oriented protocol because participants must establish a connection before data can be transferred.
By performing flow control and error correction, TCP guarantees reliable, in-sequence delivery of packets.
TCP is considered a reliable protocol because it will continue to request an IP packet that is dropped or
received out of order until it is received. This module explains concepts related to TCP and how to configure
TCP in a network.
