Device and method for supporting ECMP (Equal Cost Multipath) chip on ToR in data centre

Abstract

The invention discloses a device and method for supporting an ECMP (Equal Cost Multipath) chip on ToR in a data centre. The device and the method are realized by optimizing and configuring an ECMP table item index relationship on a virtual channel of the ToR in the data centre; the device comprises target IP (Internet Protocol) address table items, ECMP set table items, ECMP member table items, outlet table items and edit information table items; one ECMP set table item is configured for each virtual channel on the ToR in the data centre; one ECMP set table item corresponds to one target IP address table item; one ECMP set table item corresponds to the plurality of ECMP member table items; one ECMP member edit information table item is configured for one target IP address table item; and furthermore, the ECMP member table items, the outlets of which are same, share one outlet table item. According to the invention, the ECMP hardware table items on the ToR can be effectively reduced; the cost of the table items can be reduced; furthermore, and the large-scale ECMP requirements in the data centre can be supported.

Description

technical field [0001] The invention relates to an ECMP chip implementation technology, in particular to a chip implementation device and method supporting ECMP on a data center ToR. Background technique [0002] Cloud computing has become a common form of current enterprise IT construction, and virtual machines widely adopted and deployed in cloud computing have almost become a basic technical model. The extensive deployment of server virtualization technology has greatly increased the computing density of the data center. Moreover, because the virtual machine itself is not restricted by the physical computing environment, it needs to be migrated to the destination in the network without restriction based on the flexible change requirements of the business. The physical location, the rapidity of virtual machine growth, and virtual machine migration have become a normal business. In this way, the network requirements of the data center are getting higher and higher, mainly ...
