NTT Communications is deploying a new inter-AS diagnostic system in its OCN Internet backbone service to monitor and diagnose anomalies in routing information between multiple ISPs. The system, which was developed by NTT Laboratories, is believed to be the first such automated inter-domain monitoring tool in use in a commercial Internet service.
NTT said that routing anomalies between "Autonomous Systems (AS)" until now could only be analyzed manually by network operators with specialized skills. It is difficult for network operators to constantly monitor huge volumes of routing information that change from moment to moment in order to discover dangerous anomalies at an early stage. There have been numerous incidents of malicious activity in this respect and the most significant Internet vulnerabilities are seen in the context of DNS and BGP.
NTT's ENCORE system places agents with monitoring and diagnostic capabilities at each ISP, integrates the information gathered by these Agents to infer routing information behavior, and analyzes the causes of anomalies. When an abnormality is detected through regular monitoring, the system diagnoses the anomaly and identifies the factors inhibiting communications. http://www.ntt.co.jp
