Understanding Gained One Layer at a Time.

The article focuses on test instruments that can analyze data and communications network protocols. In data and communications networks, protocols define how information must be organized for it to be correctly interpreted. A typical protocol is the PCI Express (PCIe) which consists of several distinct layers. A proper protocol analyzer is necessary in order to analyze high-speed data buses and for complex applications with many different protocols. GL Communications' protocol analyzers handle wireless and wired T1, E1 and Ethernet networks with as many as 50 separate protocols for each of data. NGenius® Network Monitor from NetScout is optimized to work with the protocols encountered in virtual private networks (VPN).
