Manages end-to-end message delivery in networks.Layer 4: Transport layer network protocols Establishes and terminates sessions between users.Encodes and decodes data, encrypts and decrypts data, and compresses and decompresses data.Masks the differences in data formats between dissimilar systems.Layer 6: Presentation layer network protocols Provides standard services such as virtual terminal, file, and job transfer and operations.One or more network protocols operate at each layer in the communication exchange.ДЇollowing are the detailed descriptions of the functioning of network protocols in each layer of the OSI model: Layer 7: Application layer network protocols Network protocols divide the communication process into discrete tasks across every layer of the OSI model. The upper layers deal with application issues, and the lower layers deal with data transport issues. The seven layers in the OSI model can be divided into two groups: upper layers, including layers 7, 6, and 5, and lower layers, including layers 4, 3, 2, and 1. To put this into context, here is a representation of the communication process between two network devices following the OSI model: All the layers are self-contained, and the tasks assigned to them can be executed independently. A task or group of tasks is assigned to each of these 7 layers. The OSI model splits the communication process between two network devices into 7 layers. Considered the primary architectural model for internet working communications, the majority of network protocols used today are structurally based on the OSI model. To understand the nuances of network protocols, it's imperative to know about the Open Systems Interconnection (OSI) model first.

The OSI model: How network protocols work In other words, network protocols can be equated to languages that two devices must understand for seamless communication of information, regardless of their infrastructure and design disparities. Network protocols are a set of rules, conventions, and data structures that dictate how devices exchange data across networks. Hyperconverged Infrastructure Monitoring.
