What is the protocol analyzer?
The protocol analyzer is a system that can monitor and interpret data when it moves through a computer bus or network. It can also usually collect and store a large amount of this data. Some conditions can often be programmed to automatically start and stop the packet capture process. Electronics and software engineers often use protocol analyzers to diagnose computer networks, storage devices and design new circuits. A network protocol or sniffer analyzer can also use a security violation in a cable or wireless network.
These systems come in several forms. Some are completely separate devices that cannot be used for no other purpose. Others consist of a specialized computer software that runs on a general notebook or other portable system. The third type of protocol analyzer includes software and hardware that must be used together with a general logical analyzer. Quantity available uThe data log and the possible set of conditions can start the data collection differs according to the design of a particular system.
The logical analyzer can monitor a group of signals in the electronic circuit in real time and monitor the status of the logical status of each signal. The protocol analyzer can also interpret the data presented by the signals it monitors. For example, a network analyzer can decode and display Ethernet hardware addresses, Internet protocol addresses (IP) and other packet data that goes through the monitored connection. Analyzers exist for a large number of types of network and computer bus and can often interpret dozens of common protocols. Systems can also also identify malformed packets and other types of transmission errors.
network protocols such as IP, Internet Message Access Protocol (IMAP) and Point-to-Point Protocol (PPP) are often recognized by packet analyzers. ProtocolFile axis (FTP), often supported by secure layers of socket (SSL) and many other protocols. The modern network protocol analyzer can interpret, among other things, Ethernet, FIBRE Channel or Wireless. For testing purposes, it can often generate good and erroneous network packets. The analyzer usually connects in a hub or switch, either through a conventional network port or a monitoring port that allows him to see the operation on both sides of the switch.
Data replaced between computer systems and disk units can be monitored by a special type of protocol analyzer called Analyzer Bus. Like in a network analyzer, it can interpret data on the interface of a small computer system (SCSI), serial advanced technological connection (SATA) and other types of storage buses. Such data can often be analyzed, even if they are encapsulated by other protocols for transport via Fiber Channel, IP or Ethernet. A very complex analyzer can monitorT packets moving between servers, switches and storage devices on a high -speed storage network (SAN). This type of analyzer can help tune performance, optimize resources and identify intermittent San devices.
Universal serial bus (USB), recommended standard (RS) 232 Serial and peripheral component connections (PCI ™) also have their own bus analyzers. Like storage bus, these bus buses with computer hardware include their own unique data transfer protocols and signal timing. A log -specific protocol analyzer can use an existing computer system or logical analyzer for monitoring, decoding and storing control transfers and data packets. Transactions, requirements and events of buses can be monitored for later analysis along with any detected errors and abnormalities.
