Embodiment Construction

[0031] The present invention defines the mutation of the link flow caused by the fault or the data packet forwarded by the router and the possible congestion as a sudden and destructive event, which is prevented by the detection of the router itself and evaluated by prediction without increasing additional equipment.

[0032] The following modules are provided in the network system 100:

[0033] The network management unit 110 is mainly an existing SNMP management protocol module, which reads the relevant information required for detection in its MIB storehouse, such as router forwarding data volume and each link flow, etc., and provides corresponding data information to the management unit, also for Offline threshold calculation provides data information.

[0034] The management unit 120 is mainly composed of a detection module 121 and a perception module 122, wherein the perception module 122 is equivalent to adding a forwarding state detection module on the router, which c...

Abstract

The present invention discloses a method for measuring and evaluating network burst damage event, wherein the method comprises the following steps: passive perceiving and active detecting burst event; filtering and analyzing after merging the result; dividing the event grade according to the merging result, realizing the positioning to the fault reason; determining whether an adjustment of protocol mechanism should be executed according to the grade; and checking the whole condition of adjusted network for ensuring the correctness. The invention also provides a system for measuring the network burst damage event. The system comprises a router control module, an array management algorithm module, a network management module and an off-line calculating module. The problem to be settled by the invention is cause that the router has a flow perceiving capability, realize whether the full-network link and node operate normally and whether the burst damage event is generated. The result is notified in time for adjusting the protocol mechanism. The invention provides criterion for the protocol adjustment thereby increasing the usability and reliability of network node and link and finally guaranteeing the service quality of network.

Description

technical field [0001] The invention relates to the field of computer network and information security, in particular to a method and system for measuring and evaluating network emergencies. Background technique [0002] With the rapid development of network technology, multi-next-hop network protocols emerged as the times require. In the network environment under the multi-next-hop network protocol, traffic balance has been realized through parallel transmission. [0003] In order to achieve network self-healing, it is necessary to detect and locate faults in the network. Fast and effective fault detection and accurate and rapid identification of fault types are the basis and important means to improve network availability, reliability and ensure QoS. [0004] An SNMP-based fault management in a network system provided in the prior art detects and locates faults in the network. [0005] Fault information is obtained by polling and receiving Trap messages. However, because...
