Network-to-network connections are what make the Internet possible. The "network layer" is the part of the Internet communications process where these connections occur, by sending packets of data back and forth between different networks. In the 7-layer OSI model (see below), the network lay...
Located at Layer 3 of the Open Systems Interconnection (OSI) communications model, the primary function of the network layer is to move data into and through other networks. Network layer protocols accomplish this goal by packaging data with correct network address information, selecting the appropria...
The core function of the network layer is to route variable-length packets from the source device to the destination device across one or more networks. All communications over the network layer are “connectionless.” This means there is no immediate need or capability for a destination device t...
This layer is the first network layer of any IoT system. It is responsible for the transmission of data from the 1st layer (sensors) to the 3rd layer (gateways). The data is transferred from sensors to gateways through a specific communication protocol with its unique rules, syntax, semantics...

Functions of the application layer The application layer handles the following functions: ensures that the receiving device is identified, reachable and ready to accept data; when appropriate, enablesauthenticationbetween devices for an extra layer of network security; ...
The bottom layer is the media node layer, which consists of media asset terminals responsible for signal processing, monitoring, synchronization, production, etc. The middle layer is the core network layer. Media asset terminals located in the bottom layer are connected to the IP-based sw...
The application layer is the seventh layer in the OSI model. Though the name might be deceiving, it’s not an actual application; rather, it’s a component within an application that manipulates information. It’s essentially designed to provide network services to the end user. Users can tra...
In this article, we will talk about the much-asked query of what is layer 2 network is and how its w
