Embodiment Construction

[0021] The specific implementation manners of a memory alarm processing method, device and network equipment provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The embodiment of the present invention provides a method for processing memory alarms. When the LDP module in the network switching device receives a notification that the system memory of the network switching device has entered an alarm state, the LDP module does not use the processing method in the prior art. Instead, the forwarding of the multi-protocol label switching MPLS service on the current existing label switching path LSP is maintained, and the generation of new LSPs is stopped.

[0023] According to the above-mentioned processing method of the present invention, the LDP module can maintain the current memory consumption unchanged without increasing the burden of new memory consumption. This reduces the impact of the system memory alar...

Abstract

The invention discloses a method, a device and a network device for processing memory alarm. The method comprises the step that when an LDP module in network switching equipment receives an announcement that a system memory of the network switching equipment is in the alarm state, the LDP module keeps forwarding of a multiprotocol label switching (MPLS) service on a currently existing label switched path (LSP) and stops generating a novel LSP. In the embodiment of the invention, when the network device is in the system memory alarm state, the LDP module keeps forwarding of the MPLS service onthe currently existing LSP and stops related processes of generating the novel LSP, so that when in the system memory state, the network device can keep forwarding of the MPLS service on the existingLSP and simultaneously as the novel LSP is not generated, the burden of the system memory cannot be increased on the basis of the conventional memory consumption.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a memory alarm processing method, device and network equipment. Background technique [0002] For high-reliability routers or Layer 3 switch products, ensuring the reasonable operation of the equipment under any extreme conditions is an important perspective for testing product quality. For example, when the device memory is exhausted, how to present the user with an acceptable device operating status will directly affect the user's confidence and reputation in the product. [0003] In order to achieve the above functional guarantees, the system will perform corresponding processing when it detects that the memory consumption reaches a certain threshold, which is a memory alarm. The memory alarm mechanism is as follows figure 1 As shown in , set the memory alarm line and memory alarm clear line for the router or switch. When the system memory usage exceed...
