Routing oscillation detection method

Abstract

The invention discloses a route oscillation detector which comprises a self-learning module, a monitoring module, a background data recording module, an alarming module and an information (message) sending module. Under the condition that the route is normal, the self-learning module is executed. The detector is trained according to detected target addresses. After normal path information is obtained, the background data recording module is used for recording data which are used as basic data for subsequent daily monitoring. In normal times, the detector runs at the monitoring mode, and the monitoring module is used for the real-time monitoring on the path information of targets. Simultaneously, the obtained monitoring information is compared with the basic data. When abnormal conditions are found, the alarming module is aroused timely. The alarming module acts according to preset requirements. The information sending module is used for sending alarming messages or other alarming modes. The detector can be arranged at single point or a plurality of points. The arrangement position is closer to the network edge, the business flow trend and the using awareness of users, the detecting effect of the network is better.

Description

1. Technical field [0001] The invention belongs to the field of operation and maintenance of computer communication networks of telecommunication operators. It can provide fault location and alarm for abnormal changes such as oscillation of routing table items in the data communication network based on IP protocol. The invention can be directly applied to the fields of monitoring and maintenance of large-scale IP private networks of telecom operators and enterprises and institutions. 2. Background technology [0002] The wide application of the global Internet has made the IP protocol deeply rooted in the hearts of the people. IP protocol has become the de facto industry standard because of its simplicity, effectiveness and openness. The IP protocol makes the interconnection of heterogeneous networks convenient and feasible, especially its great inclusiveness to the underlying communication technology; the IP protocol uses a globally unified addressing method, which shield...

Problems solved by technology

[0016] 2. Although the algorithm analyzes router routing table items, it basically has no quick positioning and alarm functions, and no network management system alarm interface

[0017] 3. The algorithm can only try its best to avoid routing oscillations, loops, or other abnormalities caused by changes in hardware ports and links, and performs poorly in situations such as human configuration errors, routing exceptions, and security incidents caused by external force introduction;

[0018] 4. As far as the routing protocol level is concerned, the algorithms are all developed for their own target protocols, and the scope of use is too narrow

Only focus on core routing without paying attention to business data flow, and cannot artificially select specific targets of interest

[0020] 6. It is basically still in the stage of theoretical research in the laboratory, not suitable for daily network maintenance environment
