Embodiment Construction

[0039] The embodiment of the present invention provides a method for service load sharing, the core idea of ​​which is: in the whole network OSPF (Open Shortest Path First, Open Shortest Path First) dynamic routing environment, for links with different bandwidths, adjust the different bandwidths The cost value of the link of the low-bandwidth link is the same as the cost value of the high-bandwidth link, and the routes of at least two mutually backup links of each service are configured as equal-cost routes. And according to the priority of the service, in the process of deriving routes for services with equal-cost routes, configure routing policies so that services with different priorities occupy links with specific bandwidth: services with high priority occupy high-bandwidth links, priority Low-level services occupy low-bandwidth links. The high-bandwidth link and the low-bandwidth link serve as backups for each other. The embodiment of the present invention is described b...

Abstract

The invention discloses a method and an equipment for the service load sharing. The method of the service load sharing comprises the following procedures: at least two mutual back-up link routes of each service are configured as an equivalent route; when the route is elicited for the service with equivalent route, the routing policy is configurated according to the priority level of the differentservice, to ensure that the service of the different priority level can occupy the link of the specific bandwidth. The invention realizes that the service load sharing is performed on the basis of route, the route is dynamically adjusted according to the OSPF dynamic routing protocol, the symmetry of the service route is ensured, and the reliability of the network between the headquarter of the enterprise and the branch of the enterprise is enhanced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and equipment for sharing service loads. Background technique [0002] With the rapid development of LAN technology, the business of LAN is growing explosively. There are many factors that affect the service quality of a LAN, and one of the key factors is the egress link from the LAN to the WAN. At present, when an enterprise branch accesses the enterprise headquarters network through the WAN, in order to improve reliability, a low-bandwidth link is usually introduced as a backup link to improve the availability of the WAN link. However, services are not run on the backup link, and the backup link will be enabled only when the primary link fails, which is a serious waste of bandwidth for enterprises. [0003] Business within an enterprise can usually be divided into two categories: production business and office business. The two businesses are of differ...
