Communication protocols offer a means for information to be sent and retrieved from different locations. Different protocols serve different purposes. Some protocols are for security purposes, others for convenience. SSH, which is used to secure computers connected to an insecure network, can also be used by network administrators to remote control a system. SMS is another common protocol that allows you to send text messages over cellular networks. Although SMS can be used to send text-based messages it does not support images or videos. Multimedia Messaging service (MMS) can be used to send these messages.
Functions
The functions of communication protocols allow for data transfer between two devices. They allow for data flow control as well as addressing and synchronization. Each of these steps helps ensure that data arrives to its intended recipient in the right order. Other functions may also be performed by protocols, including limiting the flow of data.
Protocols describe the type of data to send, and the commands to send or receive that data. A protocol, like a language provides rules to govern the meaning and transmission of data. These rules are called the syntax and semantics for communications and can be described in formal ways.
Layers
In communication protocols layers refers to the various components of a network. Each layer has different functions and is responsible for different types of data. The network layer deals only with addresses, while physical layers deal with physical mediums. Both the physical and logical layers have rules that regulate how data can flow through a network.
A single protocol can be broken down into multiple layers. These layers are then organized according to functionalities. Each layer is designed to solve a specific class of problem. Messages can be sent through these layers by selecting one protocol from each layer and adding a protocol selector to it.
Security
Security of networks is one of cybersecurity's most important areas. Communication protocols are essential in protecting network resources. The proliferation of computer networks has led to an increase in cybercrime, and protocols help ensure that networks are as secure as possible. Protocols govern the data flow within a network to ensure that it is secure and protected.
Modern internet security protocols can protect against malicious actions and keep communications private. Antivirus software, firewalls and anti-spyware programs are all part of these protocols. A few programs filter the content of web pages to identify annoying issues. Secure communications includes all these security features.
Interoperability
To provide a link between two computers, communication protocols are used often. To test their interoperability, protocols should be observed by IUTs to observe how they behave. There have been many approaches to testing the interoperability among communication protocols. One approach is to use a test-derivation method. This allows test cases to automatically be generated.
Conformance testing is the process of ensuring interoperability across two computer systems. Conformance testing compares the implementations of two communication networks against standardized protocol specifications. This method is useful for ensuring interoperability, but has its limitations. Even though two conformant implementations might not communicate, it is possible for them to fail. Two conformant implementations may still fail to communicate due to ambiguity of protocol standards, incompatible options settings and incomplete conformance test.
