Problems solved by technology

[0004] However, when the network data flow is large, if the working mode of the NLB cluster is switched, the gratuitous ARP packets sent by the NLB cluster may be lost, resulting in an error in the output encapsulation of the three-layer forwarding, which will cause the NLB cluster to fail to respond to the service normally.

Abstract

The invention provides a detection processing method and a detection processing system of a cluster mode, and network equipment. The method comprises the following steps of: receiving heartbeat messages which are sent by servers in a network load balancing (NLB) cluster, and acquiring destination media access control (MAC) addresses of the heartbeat messages; according to the destination MAC addresses, detecting a current operating mode of the NLB cluster; and according to the current operating mode, updating the information of a forwarding table. The network equipment comprises a receiving module, a detection module and an updating module. The system comprises the NLB cluster, a client and the network equipment, wherein the NLB cluster comprises a plurality of servers. By the invention, the mode switching of the NLB cluster can be sensed in real time.

Description

technical field [0001] The present invention relates to communication technology, in particular to a detection and processing method, system and network device of a cluster mode. Background technique [0002] Network Load Balancing (NLB for short) is a server cluster technology that can support up to 32 servers to form a cluster. Each server in the NLB cluster has its own static IP address, and all servers in the NLB cluster also have a common IP address, that is, the NLB cluster address. When a user initiates a request to an NLB cluster, the user's request data packet will be sent to all NLB nodes, and then the NLB service running on the NLB node will determine whether to process the data packet by itself, and if not, discard the user's request data. Bag. In the NLB cluster network, the client is connected to each server in the NLB cluster through the network device. The link connection between the client, the network device and the server is actually a logical connection...
