Load sharing method

Abstract

The present invention discloses a load sharing method. It contains When communication apparatus receive message next jump route is more than one, then according to communication apparatus supported top load shared number value obtains required stream number and distributes stream labeling for each stream. Each stream labeling value correspond unique defined next jump route, in this way route can directly select route labeling, without reading threshold value to determine corresponded route labeling, thereby avoiding performance bottleneck resulted from threshold value accessing same memory block. The present invented load sharing method fits high-speed equipment use, at the same time capable of solving large stream occurring disorder problem in additions and deletions load sharing load sharing route of current technology. Furthermore the present invention also solve non-isotonic load sharing problem.

Description

technical field [0001] The invention relates to the communication field, in particular to a load sharing method. Background technique [0002] In an actual network, due to the complex topological relationship between nodes, there are often multiple paths to a destination. Multiple paths may be reachable, and they are equal to each other, that is, they all form routes. In this way, there will be multiple equal-cost routes to a destination. [0003] Such as figure 1 As shown, there may be three paths from node R1 to R8, and if the route calculation treats these three paths as equal-cost routes, then at node R1, a packet faces three choices. [0004] The first road: R1-》R2-》R3-》R4-》R8 [0005] The second road: R1-"R5-"R8 [0006] The third road: R1-》R6-》R7-》R8 [0007] For online traffic, sometimes in order to achieve link backup or expand traffic, a sharing method is also adopted, that is, there will be multiple paths to the same place, and traffic exists on multiple pat...
