The deployment and use of Internet/Intranet are growing rapidly, leading to a significant change in the computing mode of enterprises and consumers. The market has put forward the demand for traffic statistics and management technology, and requires this technology to effectively provide the information necessary to record the utilization of network and application resources. To this end, Cisco Systems introduced a new exchange technology, NetFlow exc

The data stream service, also known as NetFlow, is a network protocol that collects IP traffic information as records and sends them to the Collector for traffic analysis, it is a new technology that is being gradually improved. NetFlow provides network capacity planning, trend analysis, and data priority information for service providers and enterprises. This technology can also be used for IP-based billin

To this end, Cisco Systems has introduced a new Exchange technology--netflow Exchange in i

In this era of rapid development of Internet-based e-commerce, it is a challenging task to gain a firm foothold in the fierce competition environment. Therefore, service providers and enterprises must pay close attention to the latest development of Internet-related technologies. We have noticed that Cisco's IOS switching architecture has recently introduced two new technologies: Cisco fast forward transmission CEF) and network data flow NetFlow) serv

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 config

software, this kind of software is an effective tool to judge the flow of abnormal traffic, through the monitoring of traffic size change, can help network management personnel to find abnormal traffic, especially the flow of abnormal traffic flow, so as to further find the source address and destination address of abnormal traffic.(3) Protocol analysis technology.Protocol analysis technology is used to solve the understanding of what protocols and applications users use, including protocol and

protocol and application identification, packet decoding analysis and so on.4 the difference between NetFlow and SflowCurrent traffic-based solutions are mainly divided into sflow and NetFlow two kinds.
