Abstract
Critical network management applications increasingly demand
fine-grained flow level measurements. However, current flow
monitoring solutions are inadequate for many of these
applications. In this paper, we present the design,
implementation, and evaluation of CSAMP, a system-wide approach
for flow monitoring. The design of CSAMP derives from three key
ideas: flow sampling as a router primitive instead of uniform
packet sampling; hash-based packet selection to achieve
coordination without explicit communication; and a framework for
distributing responsibilities across routers to achieve
network-wide monitoring goals while respecting router resource
constraints. We show that CSAMP achieves much greater
monitoring coverage, better use of router resources, and enhanced
ability to satisfy network-wide flow monitoring goals compared to
existing solutions.
