Problems solved by technology

However, the acknowledgment and timeout retransmission and flow control adopted by the classic TCP protocol are only applicable to ground communication links, and are not suitable for space (satellite) communication links with large transmission delay and high error codes.
The reason is that if the classic TCP protocol is used, the space (satellite) communication link has a large transmission delay and high bit error characteristics, which will lead to a decrease in the throughput of the space (satellite) network and obvious congestion.

Embodiment 1

[0034] Example 1. consider as figure 2 Shown space (satellite) communication environment, the class "three-way handshake" connection mechanism of the present invention is as figure 1 shown. It includes an end-to-end connection and three sub-connections. In order to establish an end-to-end connection between users, end user 1 needs to initiate a three-way handshake with end user 2 ( figure 1 middle solid line). First, end user 1 sends a connection request SYN1 to end user 2. When the request SYN1 reaches gateway A, gateway A forwards the request SYN1 to gateway B, and then gateway B forwards the request SYN1 to end user 2; when end user 2 receives After requesting SYN1, end user 2 sends a confirmation ACK_SYN1 to end user 1, confirming that the connection request SYN1 has been received, and will open the connection; when the confirmation ACK_SYN1 arrives at gateway B, gateway B opens the sub-connection with end user 2 (such as figure 1 As shown by the dotted line a), gatew...

Abstract

The invention discloses a TCP split connection method suitable for a space communication network. The connection method comprises the following steps: a request SYN 1 is sent to a terminal user 2 by aterminal user 1 and transferred to a gateway B by a gateway A; the request SYN 1 is transferred to a terminal user 2 by the gateway B; the terminal user 2 receives the request SYN 1, sends an acknowledgement ACK_SYN1 to the terminal user 1 and transfers the acknowledgement ACK_SYN1 to the gateway A by the gateway B; then, the gateway A transfers the acknowledgement ACK_SYN1 to the terminal user 1; and the terminal user 1 receives the acknowledgement ACK_SYN1 and sends an acknowledgement signal ACK1 to the terminal user 2. The TCP split connection method realizes TCP split at a ground gateway,effectively lessens network congestion, improves the throughput of the space communication network, is suitable for heterogeneous communications environment, such as a wireless sensing network, a self-organizing network, and the like and has favorable transformation application prospects in the fields of aerospace, military, social economy, and the like.

Description

technical field [0001] The invention relates to a communication network connection mechanism, in particular to a TCP split connection method suitable for a space communication network. Background technique [0002] For a long time, the classic TCP (Transmission Control Protocol, Transmission Control Protocol) protocol has been widely used in fields such as network and computer communication, and its main feature is high reliability of data transmission. The data transmission reliability provided by the TCP protocol is based on two reliability technologies. One technology is a connection-oriented mechanism, that is, a connection must be established between the source end and the sink end before actual data transmission. If the connection establishment is unsuccessful due to various reasons, the source end will not rush to send data to the sink end; secondly, each message transmitted to the connection needs to be confirmed by the receiving end, and unconfirmed messages are con...
