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

. Flow record: A record that contains useful information about a stream.Definition of Ipfix Convection: A series of IP packets that pass through the observation point within a certain time interval. IP packets that belong to the same stream have some of the following common properties:1. Some IP layer header fields (for example, destination IP address), Transport Layer header fields (such as destination ports), or Application Layer header fields (such

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

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.

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

(PROBE), the interface between "probe" and software is usually private interface, third party software is unusable, and the solution of this kind of hardware and software is usually expensive and deployment is not very convenient. The analysis technology based on real-time grasping package provides detailed protocol analysis data, but lacks the statistic and trend analysis of user traffic access, and can only analyze the packets flowing through the interface in a short time, which cannot meet t

. 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

For comprehensive communication intelligence, it can also think of the device flow profiling software, which can be used in different order or users to check the use of data, in different time to check the data, and related to multiple origins of the communication data, such as NetFlow and Ipfix. Looking to the future, some of the leaders in it should focus on new skills in ord
