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

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 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

Orion is a small I/O testing tool that can test random read/write and simulate mixed loads. This tool is already included in Oracle 11g, and does not need to be installed any more. It has brought a lot of convenience for I/O testing.
Of course, I still encountered some minor problems when using such a simple tool. A brief summary.First, use orion

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

(I) Definition
Orion (Oracle I/O calibration tool) is a bottleneck provided by Oracle for testing storage system performance.
As Orion is an independent tool, you do not need to create or run an Oracle database.
Orion is very simple to use. You can directly decompress the downloaded package from the official website.

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:
