Introduction

You are viewing the Northwestern University Network Flows page. CAIDA describes a flow as "a uni-directional traffic stream with a unique [ source-IP-address, source-port, destination-IP-address, destination-port, IP-protocol, TOS, input interface ID] tuple." Flow records are collected from Northwestern University routers for analysis to help in planning and troubleshooting the network infrastructure. From here you can view a few of the summary reports and graphs based on these flow records. This site is run by the Telecommunications and Network Services (TNS) group within the Northwestern University Information Technology (NUIT) division.

The data is collected, analyzed and graphed using freely available tools such as flow-tools, FlowScan, CUFlow, and other custom tools and scripts, some built and maintained by the TNS staff.
