In computer networking there are different types of rules which are used for data transmission from one device to another device on the network such as WiFi or Ethernet, these rules are called as protocols. There are two main types of protocols which are used to spread information on internet such as TCP and also used for transmission of data in the form of data packets that are called as data gram such as IP. These two protocols are completely responsible for great networking in the field of information technology.
In the field of computer networking a method which is used for different processes and device to decode the data that transmit in the form of packets from start towards end or we can say that from head to tail which is also abbreviated as headers and trailers, such process is referred as protocol analysis. It also deals with the informative data which is present in the data gram. These packets transfer data from one device to another with the help of protocols i.e. internet protocol (IP) or transmission control protocol (TCP). Protocol analysis is only applied when the data packets are going to transfer from one networking device to another device. The program or a device on which protocol analysis depends is called as protocol analyzer.
Basically the architecture of protocol analysis is based upon layering of different network protocols and different communication devices. In the protocol analysis the data which is present on one layer is communicate with other data present on the same layer and after the communication process they can transfer from one system to another networked system. Protocol analysis also plays its vital role in monitoring the traffic of networking during transmission.
Protocol Analysis Techniques:
There are different techniques of protocol analysis which are used for decoding in the best possible way.
- Protocol analysis can analyze the basic information present in the header of the data packets present in the protocol. It can divide the information into parts by using the highlight techniques.
- Some times for more data protocol analysis is used different kinds of techniques such as diagnostic techniques. In this technique it can analyze the data by using the process of hypothesis.
Some times protocol analysis can identity the advanced problems of networking by using multiple layers, such protocol is called as expert analysis. And the device which is responsible for protocol analysis is known as protocol analyzer.
A special type of device which is required to carry protocol analysis and also used for analyzing the data which is present in the data packets at a very high networking speed are known as protocol analyzer. Some times protocol analyzer used different types of multiple layers to decode the data present in the data packets; it is also used to rebuild the data packets at advanced or higher level.
Types of Protocol Analyzers:
Protocol analyzer divides into two different types on the basis of their working in transferring data, these two types are Portable protocol analyzers and distributed protocol analyzers.
Portable Protocol Analyzers:
A type of device or software which is used to collect the data from network and perform the task of data analysis and also help in monitoring the network traffic is called as portable protocol analyzers. They are very costly as compared to other devices.
Distributed Protocol Analyzers:
A type of protocol analyzer which is used to check the whole network centrally is known as distributed protocol analyzers. It consists of two main parts i.e. monitoring probe and consol. Monitoring probe is a device or a program which is required to deals different segments of network and Consol is that part which is required to check the network centrally.
