Principle I: Monitoring and management of network and equipment Management is the basis of intelligent exchange, the common sense of network management system, including performance, configuration, fault, billing and security, 5 functional domains,

First, the introduction: Currently, IP has become a routing protocol for most backbone network products. In some network environment, the user's request to the network is very high, any shutdown and storage and transportation loss will cause

1 The question of the proposed In 1999, when discussing the expansion plan of the local network of Beijing Telecom, we saw that due to the higher integration of the switch, the capacity of the meeting board was getting larger and bigger (at that

With the increase of network and the increase of the number of machines to be managed, the fault diagnosis and network analysis have become the content of large workload for network managers such as Enterprise network and Internet bar. Also

In short, all workstations in a network do not install the hard drive, and all through the network server to boot, such a network is diskless network, these workstations are called diskless workstations. People who have not had access to a diskless

Port mapping In fact, we often say that the NAT address translation, its function is to translate the address of the public network into a private address, the use of routing of ADSL broadband routers have a dynamic or fixed public network IP,ADSL

Misunderstanding, the stronger the signal, the better. First of all, let's take a look at some of the wireless product hardware indicators: transmission power, acceptance sensitivity and antenna gain. At present, the main disadvantage of wireless

Because wireless radio frequency technology does not need wiring, does not have the fetter of the cable, may establish the computer broadband data network without the geographical condition restriction, therefore has the wired network irreplaceable

In recent years, VoIP, VOD and other real-time applications in the network application of a large number of increase in real-time applications require the network to provide service assurance or differentiated services, network path delay
