Problems solved by technology

[0009] The technical problem to be solved by the present invention is to meet the actual needs of the security guarantee of the inter-domain routing system. In view of the limitations and deficiencies of the existing inter-domain routing detection methods that cannot find hidden routing anomalies and possible routing attack behaviors or inaccurate abnormal reports, it is proposed A multi-view based inter-domain routing anomaly detection method, which is a detection method based on BGP routing tables

Embodiment Construction

[0130] figure 1 It is a network connection diagram of the routing anomaly detection system of the present invention. There are two types of connections between the routing anomaly detection system of the present invention and the Internet. The first type of connection is the connection with routing servers such as RouteViews and RIPE-NCC, which is realized by HTTP or FTP services, from www.routeviews.org and www.ripe WEB sites such as .net download routing table data to construct the Internet model; the second type of connection is the connection with the routing nodes of the monitored network, such as monitoring point A, monitoring point B, monitoring point C, etc., which can be realized through Telnet or FTP , to obtain BGP routing table data from the router of the monitored network. If the router of the monitored network supports WEB-based network management, it can also use HTTP connection to download the BGP routing table for routing anomaly detection.

Abstract

The invention discloses a route abnormal detection method in domain based on multiview to solve the problem that can not find out hidden route abnormal or false abnormal report in prior art, which comprises: designing a route abnormal detection system to finish two stages work as: Internet mode construction by BGP route list information and other network topological knowledge to build Internet hierarchy relation mode and commercial interlinkage relation mode for ISP; abnormal detection and report for first general detection then special detection and treating abnormal route and generating report. This invention reinforces route monitoring system capacity obviously.

Description

technical field [0001] The invention relates to a safety supervision method in the field of computer networks, in particular to a detection method for the abnormality of the Internet inter-domain routing system and routing attack. Background technique [0002] The Internet has gradually evolved from an academic network to an important part of public information infrastructure with commercial significance. The country's economic construction and social development are increasingly dependent on the global Internet. However, the inter-domain routing (Inter-domain Routing) system, which is a key supporting part of the Internet, has many problems, such as invalid routing, prefix hijacking, routing convergence delay, routing flapping and so on. [0003] In order to construct a reliable, stable and secure inter-domain routing system, the current work in the industry can be divided into four aspects: first, the security configuration management of the routing system, including the f...
