Elasticsearch allows you to report the actual uplink and downlink throughput in bytes per second, and also reports the number of frames that are sent and lost. It displays result data in tables or graphs and stores test results in XML format, so that you can file network performance documents during network deployment and trial run, or file the baseline performance.

◎ Comprehensive layer-7 testing The integrated protocol analyzer fundamentally solves the problem that has plagued network administrators for a long time. It can be tested from the physical layer to the application layer. That is, it starts from the cable test and ends with packet capture and decoding.◎ Integrate almost all network testing tools The network integ

When we use VMware virtualization software, we often find that they can all Virtualize a nic, which seems amazing. In fact, in Linux, there are two kinds of virtual backup, point-to-Point device in Tun. Tap indicates an Ethernet device. It is used as a virtual NIC Driver. Program Data receiving and sending does not directly deal with the real network card, but is transferred through the user State. In Linux
Some time ago, the virtual network card installation was required.ProgramSo in the website to collect some, find to find, did not see a separate installation, most of the said to install openvpn, and then only install the virtual network card of the tap-win32.
