Embodiment Construction

[0020] The invention relates to modifying the fast retransmission mechanism of the standard SCTP protocol, allowing multiple fast retransmissions, and using the current statistical smooth round-trip delay Srtt as the interval between two adjacent fast retransmissions. If the packet loss is caused by a transmission error, the round-trip delay will not be very large, and the scheme of the present invention will start fast retransmission before the timeout retransmission timer expires, increasing the sending probability to improve throughput; if the packet loss is caused by congestion Yes, the current round-trip delay will be very large, the solution of the present invention will adopt the timeout retransmission mechanism of the existing protocol, and the congestion control window will be the lowest. Therefore, the present invention can be applied not only to wired networks, but also to wireless networks.

[0021] The present invention will be described in further detail below in...

Abstract

The invention discloses a wireless network congestion control method based on a stream control transmission protocol (SCTP) and mainly solves the problem of low network throughput when data are transmitted by using a standard SCTP in wireless channel environment. The method comprises the following steps of: (1) establishing an SCTP session; (2) performing congestion control, and updating a smooth round-trip time (Srtt) value; (3) quickly retransmitting a data packet which is reported to be lost for four times, and setting the updated Srtt value as the time of a quick retransmission timer of the data packet; and (4) when the quick retransmission timer expires, if the data packet does not receive a reply, quickly retransmitting the data packet again. The wireless network congestion control method has the advantages that by improvement of the conventional SCTP, the network throughput during data transmission is improved, and the method can be applied to wireless network environment.

Description

technical field [0001] The invention belongs to the technical field of network communication, and particularly relates to a method for controlling network congestion by adopting a stream transmission control protocol SCTP in a wireless local area network Wlan, which is used for improving the throughput of a wireless channel sending end. Background technique [0002] The SCTP protocol is a protocol newly defined by the IETF in 2000. It was originally designed to transmit telecommunication signaling SS7 on the IP network, and introduce some reliable features of the SS7 signaling network into the IP network. Like the transmission control protocol TCP and the datagram protocol UDP, it is a protocol belonging to the transport layer. SCTP is a reliable transport layer protocol that provides stable and orderly data transfer services between two endpoints and can protect data message boundaries. The protocol has the characteristics of multi-homing, multi-flow, message framing, conf...
