Problems solved by technology

[0005] The embodiment of the present invention provides a load sharing method and device, which are used to solve the problem that when the service parameters configured by each load sharing device in the TRILL network are different in the prior art, the data message is sent to the device that cannot process the message to which the message belongs. The problem of service interruption caused by the service load sharing equipment being discarded

Embodiment 1

[0081] The TRILL network includes a plurality of load sharing devices, and the plurality of load sharing devices establishes a communication connection with at least one data sending device, and the message sent by the data sending device to the data receiving device is shared and forwarded by the plurality of load sharing devices, thereby Implement traffic load balancing on the TRILL network.

[0082] For example: if figure 1 As shown, there are four load sharing devices GW1, GW2, GW3, and GW4 in the TRILL network. The above four load sharing devices establish a communication connection with a data sending device 101, and the data message sent by the data sending device 101 is received by the above four load sharing devices. The sharing device shares and forwards, and the load sharing device that receives the data message sent by the data sending device 101 forwards the data message to the first data receiving device 102 or the second data receiving device 103 .

Abstract

Disclosed are a load sharing method and device; dividing load sharing devices being capable of processing the same service into at least one load sharing set, and distributing one virtual nickname for each load sharing set; establishing a mapping table, the entries of the mapping table comprising the virtual nickname of the load sharing set and a corresponding relationship of the services, and achieving traffic load sharing in the TRILL network using the mapping table. Since each load sharing device in the load sharing set can forward the packet of the same service, the problem of sending the packet of a certain service to a load sharing device not capable of processing the service will not be generated when the load sharing set is selected, such that the service interruption problem due to packet disposing can be avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a load sharing method and device. Background technique [0002] In a multi-link transparent interconnection (English: Transparent Interconnection of Lots of Links, abbreviation: TRILL) network, use the virtual alias (English: nickname) technology to realize the load sharing of TRILL network traffic, that is, virtualize multiple load sharing devices into A virtual device assigns a virtual nickname to the virtual device, and the multiple load sharing devices use the virtual nickname. When forwarding a message based on the virtual nickname, the message will be sent to the Determined to use the virtual nickname on a load sharing device. [0003] However, the above-mentioned technology for implementing load sharing in the TRILL network needs to be configured with the same service parameters for forwarding various types of packets on each load sharing device. Taking th...
