The Protocols section deals with various network protocols found in today's networks.  The aim of this section is to help understand the fundamentals of network protocols, how they work, where they are used and in which way they all work together to provide reliability and functionality for our applications, services and users.

Protocols such as TCP, IP, ICMP others are analysed in greater depth and therefore a dedicated sub-section has been provided, while other protocols are analysed on a single article with compromising its quality.
