Two technologies in a switch

CEF Technology With the gradual popularization of the network, the data transmission mode of Internet has changed greatly. The data travels more frequently between different networks, which makes it possible to have a large number of short lifetime IP packets in the network, and their destination addresses are often quite different from the topological structure. CEF is created in such a context, mainly for the optimization of network data transmission characteristics. CEF is a completely topo

Go Network flow monitoring with Open VSwitch

With network virtualization, the software switches (such as Open VSwitch) on the servers act like the edge switches. So, to gain insights into the network flow behavior, it becomes important to has some sort of flow monitoring technique t o Analyze the traffic through these switches. NetFlow and SFlow are the "most widely used flow monitoring approaches." To monitor the flows, the switches need to be configured to export and send the traffic data to a

Multi-stream protocol analysis based on single collector

Streaming (flow) based analysis technology in network industry There are four kinds of NetFlow, Sflow, Cflow and NetStream. NetFlow is Cisco's unique technology, it is both a traffic analysis protocol, but also a flow-switching technology, as well as the industry's main IP billing method. NetFlow can answer questions about IP traffic, such as who is at what time
