Load sharing method and device of data center communication equipment

Abstract

The invention discloses a load sharing method of data center communication equipment, which comprises steps as follows: data center communication equipment regularly reads flow conditions of port group load balancing to acquire occupation conditions of each port; and a forwarding table and a Hash result modulo value in the message forwarding process are adjusted according to the occupation conditions. The invention also discloses a load sharing device of data center communication equipment. By using the scheme disclosed by the invention, static / dynamic combined load sharing of the data center communication equipment can be implemented, so that the ports can carry balanced loads and satisfy the requirements for linear speed.

Description

technical field [0001] The invention relates to communication technology, in particular to a load sharing method and device for data center communication equipment. Background technique [0002] As the core of the business network, the data center is facing many challenges. Scalability, flexibility, high performance, reliability and security are all requirements for the data center. The most important point is that when access requests increase rapidly, the server must still ensure fast and stable delivery of applications to the client, and one of the most important technical guarantees is load balancing technology. [0003] Load balancing is generally used to improve the overall processing capacity of the network, and improve reliability, availability, and maintainability. The ultimate goal is to speed up the response speed of the business, thereby improving the user experience. After load balancing, it will solve the unbalanced state of task scheduling and resource occupa...

Problems solved by technology

[0004] Among them, the port load sharing of data center communication equipment is a very important aspect of the entire load sharing function. The current port load sharing of communication equipment is a static method. Several ports form a port aggregation group, and each port occupies a position. , when the packet is forwarded, according to the hash algorithm of load sharing, the field used as the key word of the hash is obtained for hash calculation, and finally the hash result is taken as the remainder according to a fixed number, and the result is the serial number in the port group, which is reported The text is forwarded by the port where the serial number exists. This is a static port load sharing method, which can play a role in load sharing, but there will be load imbalance. In extreme cases, some ports are overloaded. Some ports may be loaded with very little traffic, which cannot achieve the purpose of load balancing and cannot fully utilize the bandwidth resources of each port.

If the dynamic load sharing method is used, although the load of each port can be balanced, the performance is relatively poor and cannot meet the requirements of wire speed.
