WebA Flow network is a directed graph where each edge has a capacity and a flow. They are typically used to model problems involving the transport of items between locations, using a network of routes with limited capacity. Examples include modeling traffic on a network of roads, fluid in a network of pipes, and electricity in a network of circuit components. WebNetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network flow. By analyzing NetFlow data, you can get a picture of network traffic flow and volume. NetFlow is a one-way technology, so when the server responds to the initial client request, the process works in reverse and creates a new flow ...
