Method for quickly calibrating multi-level forwarding load balance and multi-level forwarding network system

Abstract

The invention relates to a method for quickly calibrating multi-level forwarding load balance of a multi-level forwarding network and a multi-level forwarding network system based on the method. Except the forwarding node of the last level, each forwarding node of each level monitors the load state of each forwarding node of the next level, determines the forwarding priority according to the load weight of the forwarding node of the next level, and preferentially forwards the data which needs to be forwarded to the forwarding node with the lightest load of the next level; if high-priority forwarding fails, the secondary-priority forwarding nodes are sequentially selected to forward the data; the forwarding nodes sending the data form a forwarding source node; and the nodes receiving the data form a forwarding destination node. Through the method and system provided by the invention, the load balance among the forwarding nodes as well as the detection and processing on the link and network system conditions are realized so that the resource utilization of the entire network system is optimized; and the core algorithm of the method can also be used for performing load balance at a server end.

Description

technical field [0001] The present invention relates to a multi-level forwarding load balancing method for a multi-level forwarding network and a multi-level forwarding network system based on the method. The method is especially suitable for load balancing between forwarding nodes, and can also be used for load balancing between servers. It is especially suitable for multi-level forwarding networks that forward unicast / multicast data, and can especially realize the even distribution of network bandwidth of streaming media transmission links in multi-level forwarding network systems. Background technique [0002] Now we are in the information age, with the rapid development of society and the diversification of people's demand for network applications, the requirements for network speed and bandwidth are also increasing, and improving network bandwidth and server processing capacity by improving hardware facilities will cost a lot Too high, therefore, to achieve load balanci...

Problems solved by technology

[0004] However, the above-mentioned load balancing algorithm still has the following disadvantages: one, the existing load balancing algorithms focus on solving the load balancing problem on the server side, and cannot realize the load balancing of the entire network; two, the existing load balancing algorithms do not have the ability to Detection and processing of network system conditions (such as network failures, server system failures, and application service failures, etc.). This server will inevitably cause a large number of service requests to be lost, failing to meet the requirements of uninterrupted availability
