- Current Problem Statement
Current FlowRule service collects all flow information from all devices at every time interval(default 10 seconds). Current FlowRule service collects all flow information from all devices at every time interval(default 10 seconds). This mechanism may cause performance degradation issue at each collection time in a large-scale real carrier network due to the number of switches and its associated flows (for example; WAN: ~500 Routers, ~10K ports, ~1-10M flows per port). To overcome performance problem in a simple way, we can maintain collection time interval value with a large number. It then generates another critical issue: lack of accuracy. - In this phase, we will develop an effective flow monitoring scheme called, Adaptive(Efficient) Flow Sampling Service that can minimize collection computing overhead and provide more accurate flow statistics
