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
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

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:
