This article mainly introduces what the network layer of the blockchain core technology architecture in the computer network mainly includes, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

The network layer of the blockchain core technology architecture mainly includes: 1, network management, including the use, integration and coordination of hardware, software and manpower, in order to monitor, test, configure, analyze, evaluate and control network resources; 2, P2P network; 3, HT;4, discovery node; 5, heartbeat service

The operating environment of this tutorial: windows7 system, Dell G3 computer.

The network layer of the blockchain core technology architecture mainly includes:

A, network management

B, P2P network

C 、 HT

D, discovery node

E, heartbeat service

Network management

Network management includes the use, integration and coordination of hardware, software and manpower in order to monitor, test, configure, analyze, evaluate and control network resources, so that some of the needs of the network can be met at a reasonable price. such as real-time performance, quality of service and so on.

There are several common ways of network management:

SNMP management technology

RMON management technology

Network Management based on WEB

P2P network

Peer-to-peer network (Peer to Peer,P2P network), that is, peer-to-peer computer network, is a distributed application architecture that distributes tasks and workloads among peers (Peer). It is a form of networking or network formed by peer-to-peer computing model in the application layer.

"Peer" in English has the meaning of "peer, partner, peer". Therefore, literally, P2P can be understood as peer-to-peer computing or peer-to-peer network. Some domestic media translate P2P as "peer-to-peer" or "end-to-end", while academia uniformly call it peer-to-peer network (Peer-to-peer networking) or peer-to-peer computing (Peer-to-peer computing), which can be defined as: network participants share part of their hardware resources (processing capacity, storage capacity, network connectivity, printers, etc.), these shared resources provide services and content through the network. Can be directly accessed by other peer nodes (Peer) without going through intermediate entities.

Participants in this network are both Server and Client of resources, services, and content.

In the P2P network environment, multiple computers connected to each other are in a peer-to-peer position, each computer has the same function, there is no master-slave distinction, a computer can be used as a server, set shared resources for use by other computers in the network, and can also be used as workstations. Generally speaking, the whole network does not rely on dedicated centralized servers, and there are no dedicated workstations.

Each computer in the network can not only act as the requester of network services, but also respond to the requests of other computers, providing resources, services and content. Usually these resources and services include: information sharing and exchange, computing resources (such as CPU computing power sharing), storage sharing (such as cache and disk space use), network sharing, printer sharing and so on.

HT (end-to-end bus technology)

HT is the abbreviation of HyperTransport. HyperTransport is essentially an end-to-end bus technology designed for the interconnection of integrated circuits on the motherboard, which aims to accelerate the speed of data transmission between chips. After the HyperTransport technology is used on the AMD platform, it refers to the connection bus between the AMD CPU and the motherboard chip (if the motherboard chipset is the north-south bridge architecture, it refers to the CPU to the north bridge), namely the HT bus. Similar to the front-end bus (FSB) in the Intel platform, but the Intel platform has not yet been adopted.

Thank you for reading this article carefully. I hope the article "what does the network layer of the core technical architecture of the blockchain in the computer network mainly include" shared by the editor is helpful to everyone? at the same time, I also hope that you will support it and pay attention to the industry information channel.
