Document directory Nfdump IntroductionNetFlow provides nearly real time traffic monitoring, smart Flow Filtration, aggregation and statistic evaluation, using source/destination IP addresses, protocols, etc. Web interface provides easy configuration of all components into NetFlow collectors,Devices, units etc. the NetFlow analyzer shoshould be able

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

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

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

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.

I. Introduction of Open Vswitch1.1 OverviewOpen Vswitch is a high-quality, multi-tier virtual switch that uses the open Source Apache 2.0 license Agreement, developed by Nicira Networks, to implement code as portable C code.Its purpose is to allow large-scale network automation to be extended by programming, while still supporting standard management interfaces and protocols (e.g. NetFlow, SFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In addition, it is de
