Application layer is sent to TCP layer for data flow transmitting between netting, being indicated with octet, and then TCP is data flow
Divide the message segment (maximum transmission unit of the data link layer of the network usually connected by the computer of suitable length into
(MTU) limitation).Result packet is transmitted to IP layers by TCP later, and packet is sent to by it by network the TCP of receiving end entity
Layer.TCP just gives one serial number of each packet to guarantee that packet loss does not occur, while serial number also ensures and is transmitted to receiving end entity
Packet received in-order.Then receiving end entity sends back to a corresponding confirmation (ACK) to the packet having had successfully received；If sent
End entity does not receive confirmation in the reasonable round-trip delay (RTT), then be assumed to have lost will for corresponding data packet
It is retransmitted.Whether TCP is wrong come inspection data with a verification and function；Verification will be calculated when sending and receiving
With.
