Visual analytics for BGP monitoring and prefix hijacking identification
2012
IEEE Network
Preserved Fulltext
The control plane of the Internet relies entirely on BGP as inter-domain routing protocol to maintain and exchange routing information between large network providers and their customers. ...
Finally, we present an analysis of a real validated case of prefix hijacking, which took place between April and August 2011. ...
The algorithms can be enriched with additional data sources like traffic flows or router configuration files to improve the diagnosis of BGP anomalies. ...

Applications of anomaly detection typically stem from the perspectives of network monitoring and network security. ...
In this chapter we review three main approaches to network anomaly detection: statistical methods, streaming algorithms, and machine learning approaches with a focus on unsupervised learning. ...
In a separate work [36] , Mandjes et al. consider anomaly detection in voice over IP network based on the analysis of the variance of byte counts. ...

BlameIt uses passive diagnosis, using measurements of existing connections between clients and the cloud locations, to localize the cause to one of cloud, middle, or client segments. ...
In particular, we focus on instances of latency degradation and design a tool, BlameIt, that enables cloud operators to localize the cause (i.e., faulty AS) of such degradation. ...

Unexpected temporal and spatial changes of inter-AS routing behavior often lead to the necessity of on-demand inter-domain routingadjustment. ...
Some evaluation results indicate that VR can effectively change routing over BGP data on the actual Internet and some control scenarios based on policy descriptions demonstrate the validity of our basic ...
For diagnosis of inter-AS routing anomalies, we have proposed a CDPS approach [4] to cope with these problems. Simple centralized models are difficult to apply. ...
