Embodiment 1

[0053] Embodiment 1 of the present invention provides a data packet scheduling method and system for multi-path cross-protocol transmission.

[0054] On the one hand, the data packet scheduling method for multi-path cross-protocol transmission described in Embodiment 1 of the present invention realizes improved out-of-sequence data packet scheduling and realizes performance optimization of multi-path cross-protocol transmission. Specifically include:

[0055] In the heterogeneous environment of multi-network and multi-protocol integration, the first transmission unit acts as an intermediate device at the sending end, and the second transmission unit acts as an intermediate device at the receiving end. The transmission unit configures available interfaces and protocols for forwarding and processing packets; after the transmission unit perceives the reachability information of the opposite end, it confirms the establishment of an end-to-end connection bound with interface attrib...

Embodiment 2

[0079] Embodiment 2 of the present invention provides a data packet scheduling method and system for multi-path cross-protocol transmission. By implementing the present invention, multiple links are established between transmission units based on the available interfaces to form a multi-path cross-protocol transmission system. , load balancing and the constraints of orderly transmission of data packets, build a data allocation and scheduling model for each link and implement strategies, adaptively improve the congestion of each sub-flow, reduce the performance difference between concurrent links, and reduce data packet chaos sequence to prevent buffer congestion at the receiving end.

Abstract

The invention provides a multi-path cross-protocol transmission data packet scheduling method and system, and belongs to the technical field of communication. A first transmission unit is used as an intermediate device of a sending end. Asecond transmission unit is used as an intermediate device of a receiving end, and the first transmission unit and the second transmission unit are both configured with physical interfaces and transmission protocols for forwarding packets; after the transmission unit senses reachable information of the opposite end, a plurality of end-to-end links bound with the physical interface attributes are established; and the second transmission unit is configured with a virtual network loop or a physical port corresponding to the link, senses the time delay, the throughput and the congestion state of the link in real time, and adjusts the sending rate of the link, so that the customizable time delay of packet forwarding and the alignment of the sending rate arerealized. According to the invention, the performance difference between concurrent links is reduced, the disorder of data packets is reduced, the congestion of a cache region of a receiving end canbe prevented, and the overall throughput of a multi-path cross-protocol transmission system and the disorder of control data are improved on the premise of ensuring the safety.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data packet scheduling method system for multi-path cross-protocol transmission. Background technique [0002] The widespread deployment and application of cellular networks, wireless local area networks, wireless metropolitan area networks, and wireless ad hoc networks builds a heterogeneous network environment where multiple networks converge, enriching the options for user network access. In the face of large-capacity service transmission, traditional single-channel communication has the characteristics of transmission link congestion and low throughput, which can no longer meet user experience requirements. [0003] In order to improve the utilization of network resources, multi-path transmission technology has begun to develop rapidly. Its core idea is to distribute data streams to multiple links in the way of resource sharing to improve network utilization and reduc...
