Load balancing device and load balancing method

Abstract

The invention provides a load balancing device and a load balancing method both of which can improve resource distributing efficiency while can balance the service distribution of servers and flow distribution of a route. The services are divided into a plurality of service blocks according to the server resource requirements and network transmission resource requirements of the services, spare server resources and spare network transmission resources of a data center network are divided into a plurality of resource blocks, the spare server resources and the spare network transmission resources of the data center network are monitored, a corresponding relation between the combination, specific to a server, of the spare server resources and the spare network transmission resources and the resource blocks is set, the service block to which the request requirement entering the data center network belongs is identified, and the combination of the spare server resources and the spare network transmission resources is distributed to the service request based on the corresponding relation between the service block and the corresponding resource block.

Description

technical field [0001] The invention relates to a load balancing method, in particular to a load balancing device and a load balancing method applied in the data center field to simultaneously improve the utilization efficiency of network resources and server resources. Background technique [0002] Patent document 1 (CN101431532A) proposes a load balancing method in a content distribution network. The resource management device collects resource information and distributes it to the load balancing device, and the load balancing device selects an appropriate cache server according to the received resource information and the predetermined resource allocation strategy, thereby improving system performance and efficiency. The resource information used therein includes the storage capacity of the server, the used percentage of the storage capacity, the CPU usage rate, the total bandwidth of the server egress, and the bandwidth usage rate. The manifestation of the resource allo...

Problems solved by technology

[0003] In the load balancing method mentioned in patent document 1, there are following defects: only the ability of the server to handle business and the load balancing of the server are considered, and the available bandwidth of the network link reaching the server is not considered, so in the network that is prone to congestion In the environment, the quality of services cannot be effectively guaranteed, especially for services with high bandwidth requirements

However, the method in this literature still has the following problems: it only considers the allocation of optimal resources for the current business needs, but does not consider the differences in business requirements for different resources and the maximization of global resource utilization, so it is difficult to adapt to the business Dynamic changes, especially the sudden emergence of certain services that require unbalanced resources in the future

The former will reduce the performance of the business, while the latter will cause a lot of waste of bandwidth resources
