The proposed method for communications between computer networks at the application layer implies receiving messages from the external network by a data internetworking computer, storing the messages in the random-access memory unit of the internetworking computer, and transmitting the messages within the ...
when appropriate, enablesauthenticationbetween devices for an extra layer of network security; makes sure necessary communication interfaces exist, such as whether there is an Ethernet or Wi-Fi interface in the sender's computer; ensures agreement at both ends on error recovery procedures,data integrit...
Who needs to understand the application layer? Though the OSI model has changed since its inception, many computer systems still rely on it. The model claims to help troubleshoot network problems. Therefore, there’s value in the OSI model, especially the application layer. ...
1. Overview of the Application Layer Role and Function Interface to Network Services: The Application Layer in theOSI modelis the conduit through which end-users and applications communicate with network services. This layer is the user’s gateway to the network, where application-level communication...

The studies of [9], [10], [11] consider multipath routing at the network layer, as an improvement to the single-path IP routing. We, in contrast, consider multipath data transfer at the application level, without any change to IP routing; consequently, our approach is easy to deploy. ...
The invention relates to a computer network analytical method and a system, which pertain to the technical field of computer network communication. The method comprises the steps that a network protocol analytical procedure and a communication content analytical procedure are carried out in a network ...
