Measurouting Approach for Flow Utility in Routing Assisted Traffic Monitoring
The network operators are interested in monitoring passing traffic in a network for reasons of traffic accounting, debugging or troubleshooting, forensics, and traffic engineering. Previous research has focused on monitor placement across the network for maximizing the monitoring utility. But, traffic characteristics and measurement objectives can change dynamically, rendering a placement of monitors suboptimal. It will not be the feasible solution to dynamically reconfigure measurement infrastructure. The problem is addressed by strategically routing traffic subpopulations over fixed monitors. This approach is referred as MeasuRouting. The challenge of MeasuRouting to work within the intra-domain TE operations that are geared for utilizing bandwidth resources and meeting Quality-of-Service (QoS).
