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,

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 f

likelysampled(particularly in high-speed switches). Next, the sampled packet header isDecodedTo extract key fields. AHashfunction is computed over the keys on order to look up the flow record in theFlow Cache. If an existing record was found, its values were updated, otherwise a record is created for the new flow. Records flushed from the cache based on protocol information (e.g. if a FIN flag is seen in a TCP packet), a timeout, Inactivity, or when the cache was full. The flushed Records is fi

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

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--

In fact, CEF has become an efficient Internet switching architecture. NetFlow technology　 Like CEF, NetFlow is also a new technology th

NetFlow Analyzer Vulnerability (CVE-2015-4418)NetFlow Analyzer Vulnerability (CVE-2015-4418) Release date:Updated on:Affected Systems: ManageEngine Netflow Analyzer Description: Bugtraq id: 75068CVE (CAN) ID: CVE-2015-4418NetFlow Analyzer is a Web-based broadband monitoring and traffic analysis tool.The password

. ②. NetFlow: ____ In recent years, many service providers have been using NetFlow. Because NetFlow has the scalability in a large WAN environment, it can help to support the best transmission stream on the peer point, and can also be used to optimize the infrastructure evaluation based on a single service, the benefits of solving service and security problems pr

bottleneck. In order to improve the effectiveness of the transmission management message, reduce the load of the network administration workstation, and meet the requirement of monitoring the performance, the IETF has developed rmon to solve the limitation of SNMP in the growing distributed interconnection.3. Monitoring Key TechnologiesThe network monitoring system includes two core technologies: Data stream acquisition technology and network traffic

three aspects:Data stream acquisition technology solves the problem of how to get the data stream we need from different locations in the network. From the location of data acquisition, can be divided into network-based, host-based and hybrid acquisition of three kinds: (1) Flow monitoring technology. The flow monitoring technology mainly includes SNMP-based traffic monitoring and NetFlow-based
