protocol layer

protocol layer

(networking)
The software and/or hardware environment of two or more communications devices or computers in which a particular network protocol operates. A network connection may be thought of as a set of more or less independent protocols, each in a different layer or level. The lowest layer governs direct host-to-host communication between the hardware at different hosts; the highest consists of user application programs. Each layer uses the layer beneath it and provides a service for the layer above. Each networking component hardware or software on one host uses protocols appropriate to its layer to communicate with the corresponding component (its "peer") on another host. Such layered protocols are sometimes known as peer-to-peer protocols.

The advantages of layered protocols is that the methods of passing information from one layer to another are specified clearly as part of the protocol suite, and changes within a protocol layer are prevented from affecting the other layers. This greatly simplifies the task of designing and maintaining communication systems.

Examples of layered protocols are TCP/IP's five layer protocol stack and the OSI seven layer model.

Specifically, the entire technical architecture is divided into a public network infrastructure layer and a protocol layer. The chain data structure, the consensus mechanism, the P2P network protocol, the smart contract virtual machine, the cryptographic algorithm and other content are placed in the base layer of the public chain while putting the functions of the side chain and bottom chain calculations into the protocol layer.
Chainlink is built on Ethereum (ETH), yet it is said that Chainlink has started official development of its own protocol layer, which may have an adverse effect on developers using the current protocol.
The User interface aspect is at the upper business layer and the second aspect is at the lowest technological protocol layer. A profound digital transformation may start from the lowest layer up to the most top business layer to take advantage of innovative protocols, disruptive technologies, new processing software, and an end-to-end rethinking of almost all the technical and business processes.
End-to-end tools that automate service generation completely, from the protocol layer all the way up to user interfaces and mobile apps, make it possible for marketers and product managers to define the logic behind a service quickly and easily.
By 2020, the number of digital bytes produced in the world will reach 44 zettabytes, amount to each family owning 318 iPhones, a 50-fold increase from 2010; the costs to collect, process, store, and analyze data decline sharply, making data an important global bulk commodity, and titled 'new oil'; the core function of the protocol layer of SCRY is to connect more traditional financial data/aviation/competitive entertainment into smart contracts for application product development.
The protocol layer is defined by the Interlaken standard, a device interconnect standard common in data centers, conceived by Cortina Systems and Cisco Systems.
Future work aims to provide the multi protocol layer solutions in heterogeneous environments.
Due to the diversity and complexity of protocol layer, the protocols inside the module do not have common attributes, but classification contributes to understanding the protocols, as shown in Table 4.
According to multi-layer structure of protocol stack, QoS metrics are different for each protocol layer, and forms the layered QoS metrics structure in modern wireless networks.
