Communication protocols are a way to send and receive information from one place to another. Different protocols have different purposes. Some protocols are for security purposes, others for convenience. For example, SSH is used to secure access to computers connected to an unsecured network, and it is useful for network administrators who wish to control a system from a remote location. SMS is another popular protocol. It is used to send SMS messages over cellular networks. SMS is useful for text-based messages but it doesn't support videos or pictures. Multimedia Messaging Services (MMS) is required to send these types messages. It's an extension of SMS.
Functions
Communication protocols provide functions that allow the transfer of data between two devices. These protocols provide different methods to manage data traffic, such as data flow control and addressing. Each of these processes helps ensure that data arrives at its intended recipient in the proper order. Some protocols can also be used to provide a limit on data flow.
Protocols describe the type of data to send, and the commands to send or receive that data. Similarly to a language, a protocol provides rules that govern the meaning of data. These rules are also called the syntax and semantics in communications. They can be defined in formal ways.
Layers
Communication protocols use layers to refer to different parts of a system. Each layer can be responsible for different types or functions. The network layer deals in addresses, while the physical level deals with the physical medium. Rules govern how data is transmitted across a network, and both the physical layer and the logical layer have their own rules.
A single protocol may be divided into multiple layers. Functionalities are used to organize these layers. Each layer addresses a specific problem. Messages can be sent through these layers by selecting one protocol from each layer and adding a protocol selector to it.
Security
Network security is one of the most important branches of cybersecurity, and communication protocols play an essential role in protecting network resources. The rise in cybercrime is due to the proliferation and security of computer networks. Protocols are used to protect networks. Protocols regulate how data flows in and out of networks to ensure data security and protection.
Modern internet security protocols are designed to protect against malicious activities and ensure that communications remain private. They include firewalls, anti-spyware software, and programs that remove spyware and adware. Some programs also filter the contents of web pages and identify common annoyances. Secure communications covers all of these security features.
Interoperability
Communication protocols are often used for connecting two computers. The behavior of IUTs can be used to verify interoperability. There are many methods to verify interoperability of communication protocol protocols. One approach involves the use of a test derivation method. This technique allows test cases to be generated automatically.
Conformance testing refers to the process of verifying interoperability among two computers systems. Conformance testing compares the implementations of two communication networks against standardized protocol specifications. This is an effective way to ensure interoperability but it comes with its limitations. Two conformant versions may not be able to communicate. This can be due to incompatible option settings, ambiguity in protocols standards, or incomplete conformance testing.
