Abstract

The invention relates to an application method and device of TCP acceleration in an OSU, and the method comprises the steps: recognizing the type of a message received by an Ethernet interface in real time, judging the type of the TCP message when the message is the TCP message, and modifying the window size related value of the TCP message according to the pre-calculated local terminal TCP connection available window size related value and the TCP message type. Since the available window size correlation value of the home terminal TCP connection is calculated according to the currently allocated bandwidth of the OSU connection established by the home terminal and the available cache space of the home terminal equipment, the window size of the TCP message is changed by correspondingly modifying the window size correlation value of the TCP message; the bandwidth of the OSU channel can be fully utilized when the TCP message is transmitted, so that the transmission rate is improved. And finally, according to the type of the TCP message, executing a corresponding sending process on the TCP message, so that the TCP message can be quickly and efficiently transmitted.

Description

technical field [0001] The present application relates to the technical field of network communication, in particular to an application method and device of TCP acceleration in OSU. Background technique [0002] The traditional optical transport network (Optical Transport Network, OTN) technology has the advantages of large bandwidth, hard pipe, multi-service carrying capacity, and carrier-level operation and maintenance management (Operation Administration and Maintenance, OAM) mechanism, etc., and is widely used in the industry. Large-scale deployment in backbone networks and metropolitan area networks. With the development of informatization and cloud technology, the bearer demand for leased line and video services is booming. These services are characterized by small bandwidth and large quantities, requiring simple and quick bandwidth adjustment. Under the background of this requirement, Optical Service Unit (OSU) technology emerges as the times require. On the premis...
