OBS framing method and OBS framing device

Abstract

The embodiment of the invention discloses an OBS framing method and an OBS framing device. The OBS framing method comprises that: an edge node determines the amount of an ACK package received in the next round according to the amount of a TCP package comprised in a received TCP stream bursting package; the edge node determines a length threshold value according to the amount of the ACK package received in the next round and a preset minimum framing length value; and the edge node makes the ACK package received in the next round generate a bursting package according to the length threshold value, a preset optimal framing length value and a preset framing time threshold value. By adopting the technical scheme disclosed by the embodiment of the invention, the OBS framing method and the OBS framing device realize framing queue setting aiming at asymmetry of the edge node flow and the service type of the edge node in an actual OBS network, and achieve the effects of reducing end-to-end delay of the TCP and improving the transmission data amount of the TCP stream.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an OBS framing method and device. Background technique [0002] With the explosive growth of global Internet and data services, various emerging services have emerged one after another, making Internet services grow exponentially. Due to the diversity and variability of services, the traditional core switching network is no longer suitable for the continuous development of the Internet. The optical burst switching adopted by the optical network at present is a better solution to improve the processing granularity, which can meet the above-mentioned technical needs. [0003] In an OBS network, the basic switching unit is a burst packet (burst). Optical burst switching nodes include core nodes and edge nodes. The edge node aggregates the IP packets into a burst packet whose length is much larger than that of the IP packet, and at the same time sends a burst packet...

Problems solved by technology

[0009] For different types of edge nodes, the corresponding network traffic is very different due to the asymmetry of the traffic, and there will be unstable network traffic, but in the technical solutions of the prior art, no corresponding solution is proposed , various preset parameter values ​​or threshold values ​​may be affected due to changes in network traffic, which will affect the expected technical effect and reduce the data processing efficiency and quality of the network
