Research And Implementation Of A Realtime Detection Mechanism For Route Leakage

With the continuous expansion of BGP network scale,the route strategies between different autonomous domains are becoming more and more complex,and the importance of BGP protocol in realizing inter domain interconnection is increasing.However,due to the security risks of BGP itself,BGP abnormal events such as route leakage frequently occur in recent years,which poses a great threat to the stability of network environment.Therefore,how to realize the real-time detection of abnormal events of route leakage is very important to maintain a stable network environment.The route leakage detection method based on valley-free criterion will lead to mismatching and missing report,which leads to low accuracy.At the same time,the real-time performance of this method is poor.To solve the above problems,this paper proposes a real-time detection algorithm of route leakage.The algorithm optimizes the detection method based on valley-free criterion,simplifies the business relationship inference process of AS,and further introduces route stability and route leakage risk evaluation methods to filter mismatch events based on the results.Based on the proposed real-time detection algorithm of route leakage,this paper designs a real-time detection system of route leakage,which includes data acquisition module,event detection module and front-end display module.Test results show that the system can be applied to the real-time detection of route leakage,and has quite high accuracy.
