Network management

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

Common network management methods include the following:

• SNMP management technology

• RMON management technology

• WEB-based network management

P2P 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 (Peers). It is a networking or network form formed by the peer-to-peer computing model at the application layer.

"Peer" means "peer, partner, peer" in English. Therefore, literally, P2P can be understood as peer-to-peer computing or peer-to-peer network. Some domestic media translate P2P as "point-to-point" or "end-to-end", while academic circles collectively call it peer-to-peer networking or peer-to-peer computing, which can be defined For: Network participants share some of the hardware resources they own (processing power, storage capacity, network connection capabilities, printers, etc.). These shared resources provide services and content through the network and can be directly accessed by other peer nodes (Peer). without going through intermediate entities.

Participants in this network are both providers of resources, services and content (Server), and acquirers of resources, services and content (Client).

In a P2P network environment, multiple computers connected to each other are in a peer-to-peer position. Each computer has the same function, and there is no master-slave distinction. One computer can be used as a server or a device. Certain shared resources are used by other computers in the network and can also be used as workstations. Generally speaking, the entire network does not rely on a dedicated centralized server and does not have a dedicated workstation.

Every computer in the network can not only act as a requester of network services, but also respond to requests from other computers to provide 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 usage), network sharing, printer sharing, etc.

HT (end-to-end bus technology)

HT is the abbreviation of HyperTransport. HyperTransport is essentially an end-to-end bus technology designed for integrated circuit interconnection on the motherboard, with the purpose of accelerating data transmission between chips. After 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 a north-south bridge architecture, it refers to the CPU to the north bridge), that is, the HT bus. It is similar to the front-side bus (FSB) in the Intel platform, but the Intel platform has not yet adopted it.
