Load balance method and device for multiple service units

Abstract

The embodiment of the invention provides a load balance method and device for multiple service units. The method includes the steps that a controller receives service configuration information sent by a management entity, and then determines the number of load balance paths according to the service configuration information; a load balance path table corresponding to each service unit in a service chain is determining according to the number of the load balance paths, wherein the load balance path table comprises load balance marks and servers in the service units corresponding to the load balance marks; the load balance path tables corresponding to the service units are sent to service interchanger of the service units in the service chain respectively, and the service interchangers for the service units find the corresponding servers in the received load balance path tables according to the load balance marks carried in a received data package, and send the data package to the servers for processing. By the load balance method and device for the multiple service units, load balance of the multiple service units can be achieved, and cost is lowered.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for load balancing of multiple service units. Background technique [0002] With the development of Internet technology, the Internet provides more and more service content. For some service items or service content, it is usually necessary to set up multiple servers to provide services at the same time for load balancing and to avoid a single server Situations where timely service cannot be provided to multiple users at the same time. The existing load balancing method is as follows: the client sends the service request message to the load balancer through the IP network. Distributed to a server connected to the load balancer, the server sends the response message to the load balancer after processing, and finally the load balancer sends the received response message back to the client. This traditional load balancer ...

[0004] In the prior art, for the load balancer used by a single business unit, since it needs to store millions of business flows identified by IP quintuples, it needs to have a strong processing capability and is a relatively expensive device; figure 1 In the scenario of the business chain shown, if figure 1 The business switches in the network also use expensive load balancers. Since there are multiple business units, multiple expensive load balancers need to be deployed, and the cost will be very high
