1. Protocol analyzer

   Nota:

   • A "Protocol analyzer" is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel. Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol (networked or point-to-point). Each type of communication protocol has a different tool to collect and analyze signals and data.
   1. Telecom network protocol analyzer

      Nota:

      • Telecom Network Protocol Analyzer is a Protocol analyzer to analyze a switching and signaling telecommunication protocol between different nodes in PSTN or Mobile telephone networks, such as 2G or 3G GSMnetworks, CDMA networks, WiMAX and so on. In a mobile telecommunication network it can analyze the traffic between MSC and BSC, BSC and BTS, MSC and HLR, MSC and VLR, VLR and HLR, and so on. Protocol analyzers are mainly used for performance measurement and troubleshooting. These devices connect to the network to calculate key performance indicators to monitor the network and speed-up troubleshooting activities.
   2. Bus analyzer

      Nota:

      • A bus analyzer is a computer bus analysis tool, often a combination of hardware and software, used during development of hardware or device drivers for a specific bus, for diagnosing bus or device failures, or reverse engineering.
   3. IP network protocol analyzer
      1. Packet analyzer

         Nota:

         • A packet analyzer (also known as a network analyzer, protocol analyzer or packet sniffer, or for particular types of networks, an Ethernet sniffer or wireless sniffer) is a computer program or a piece ofcomputer hardware that can intercept and log traffic passing over a digital network or part of a network.[1] As data streams flow across the network, the sniffer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content according to the appropriate RFC or other specifications.
      2. IP Load tester

         Nota:

         • IP load testers are a class of protocol analyzers focused on the practical evaluation of router performance.
