Data packet multipath scheduling apparatus and method

Abstract

The application provides a kind of data packet multipath scheduling device and method, belong to wireless communication equipment technical field, network state collection module extracts each programmable switch network state information in forwarding path;The end-to-end delay information of calculation path;Multipath low delay scheduling module quantifies the value of each network protocol path according to the characteristics of delay-sensitive network service to generate path selection decision;The path selection decision generated is issued through the control plane, and cross-protocol multipath forwarding is realized based on programmable data plane;Priority queue scheduling module combines network state information according to data packet level, and data packets are dequeued according to level order.The application considers bandwidth demand when using multiple path backup to transmit data to improve delay performance;Compatible with IPv4, IPv6 network protocol, can be transmitted in cross-protocol scenario;Reduce the scheduling loss of high priority data packet and its queuing delay;Data packet level can be adjusted in real time to cope with the characteristics of network time-varying.
