Method and device for unstacking adaptation based on data center

Abstract

The invention discloses a data center-based destacking adaptation method and device, the method comprising: a server receives an LACPDU message carrying a port identifier of an access device and a unit identifier of a destacking unit where the access device is located; the received Ports of LACPDU packets carrying different port IDs and the same unit ID are bound to a port aggregation group; if accessing other servers, send an ARP request carrying source IP address and destination IP address to the access device included in the connected de-stacking unit message, so that the access device determines whether to perform ARP proxy according to the source IP address and destination IP address; among them, the source IP address is the IP address of the server, and the destination IP address is the IP address of other servers; if it is necessary to send an ARP response message , an ARP response message is sent according to the status of each port included in the port aggregation group. In this solution, the servers in the data center can be well adapted for de-stacking.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data center-based unstacking adaptation method and device. Background technique [0002] Stacking is a technology for expanding ports and simplifying management on network devices in a data center. It is a non-standardized technology. Stacking can only be completed between network equipment of the same network equipment supplier, which is a private internal implementation. The network equipment must have a stacking function, and also requires a dedicated stacking module and stacking cables. Different types of network equipment support stackable The quantity is also different. Nowadays, stacking has become a must for data center network equipment, and some people regard this technology as a virtualization technology, which realizes "multiple virtual ones" of network equipment. In this way, stacking technology has become a logical choice for building a new gener...

Problems solved by technology

[0003] However, the stacking technology also has great limitations. First, to realize the stacking of network devices, it is necessary to use stacking cables to connect two network devices to form a stacking unit. Usually, a data center includes multiple stacking units. Many stacking cables are used, and the cost of stacking cables is very high, which greatly increases the networking cost of the data center; secondly, stacking is a non-standardized technology, and network equipment from different network equipment suppliers cannot form a stack. Even network equipment from the same network equipment supplier must be of the same model and software version to be stacked, which greatly limits the networking flexibility of the data center
