We aim to design the fundamental building block of a network monitoring infrastructure that allows researchers and network operators to process and share network data across multiple sites. CoMo supports i) arbitrary traffic queries that run continuously on the live data streams, ii) retrospective queries that analyze past traffic data to enable network forensics.

Data streams may have different formats (e.g., packet sequences, flow summaries, etc.) and originate from different platforms (e.g, passive link monitors, routers, wireless access points, etc.). CoMo can operate in the presence of different devices and data sources and provide a unified data interface to queries. Multiple CoMo systems will also cooperate to rapidly disseminate queries throughout the network of monitors, allowing operators to "drill down" to relevant data locations in the network.
