how netflow works

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

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

Figure 1: Low latency software defined networking control loop The articles SDN and delay and delay and stability describe the critical importance of low measurement delay in CONSTRUCTI Ng stable and effective controls. This article would examine the difference in measurement latency between SFlow and Netflow/ipfix and their relative Suitabi Lity for driving control decisions. Figure 2: sFlow and NetFlow a

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

The deployment and use of internet/intranet is growing rapidly, and has led to a major shift in business and consumer computing patterns. The market has put forward the demand for traffic statistics and management technology, and requires that this technology can effectively provide the information needed to record the network and apply the resource utilization. To this end, Cisco Systems has introduced a new Exchange technology--netflow Exchange in i

NetFlow is a network protocol that collects IP traffic information as records and sends them to collectors such as CA NetQoS for traffic analysis. Vmware vSphere 5 supports NetFlow v5, the most common version supported by network devices. The NetFlow feature on the vSphere 5 platform provides visibility into virtual infrastructure traffic, including: Traffic from

Simple implementation of Distributed NetFlow Analysis system with OssimIn order to analyze the abnormal traffic of network, we must first understand the principle and characteristics of the abnormal traffic, and analyze the types, flow, consequence, data packet type, address, port and so on.

The layer-3 switch you know works like this. It works like a layer-3 switch. Why do we say that the L3 forwarding performance of a layer-3 switch is much higher than that of a router? Sometimes it is mentioned in many books that the software of the router is also very powerful and can almost achieve the speed limit forwarding capability. However, it is unlikely that the software can compare with the hardwa
