56, NT network card and Novell network card interoperability Hot Network Recently, a computer training center to establish a diskless NT teaching network, because the NT diskless Workstation network card has strict requirements: the number of cards (Adapter ID, that is, nod

Chapter 1 Overview Circuit Switching: The bit stream of the entire packet is continuously transferred from the source point to the end point, as if in a pipe. Packet Exchange: The entire packet is first transmitted to the adjacent node, all of which are stored and then searched for the forwarding table and forwarded to the next node. Group exchange: a single group (which is only a part of the entire packet) is sent to adjacent nodes. After the group is stored, it finds the forwarding table and f

operation mode is the most sensitive to wireless path loss and multi-path, and may not completely overwrite the mode that supports video distribution. Wireless relay can be used to expand the network connection distance. Relay can indeed increase coverage, but will occupy more spectrum. However, if you do not plan well, you still cannot guarantee full coverage. This solution is more cost-effective than the

GPRS network optimization is more complicated than GSM network optimization. GPRS system with GSM network as the bearer network, using the existing GSM wireless network, GPRS and GSM share the same base station and spectrum resour

I. fault descriptionFault Location:An electronics Bureau Fault symptom:The network is severely congested, and communication between internal hosts or even between internal hosts is interrupted. Fault details:Network Communication is suddenly interrupted, some VLANs cannot access the Internet, and access to other VLANs is also interrupted. Ping packet testing is performed in the IDC, it is found that the ping packet from the central switch to the host

Wireless network Bridge maintenance work often requires experienced network administrators to coordinate, so the performance of the network often attracts many users of the eyeball, here to introduce you several aspects. How to improve the quality of network services, enhance competitiveness? I think we must strengthen

It is believed that most home users will prefer to use the Windows XP operating system, but the Windows 2000 operating system can still be seen in many office-used computers. In the recent network management maintenance, the author after a long time careful comparison and pondering, found in the Windows 2000 system for network card device replacement operation and Windows XP system has not exactly the same

Network devices (routers, switches, firewalls, and so on) require an operating system as well as computers. Network devices use a dedicated operating system, collectively known as iOS (Internetwork Operating system, network operating system).(1) Common connection mode of network equipment:There are four common ways to

China's wireless access network is still widely used, and it is also very important to optimize the network. So I studied the GSM network optimization problem of the Wireless Access Network, I would like to share it with you here and hope it will be useful to you. With the development of the mobile communication indust

Testing tools are the means to achieve automated testing. The rational use of testing tools can not only improve the network diagnostic capability, but also facilitate network management. Generally, broadly speaking, network testing tools can be divided into physical cable tester, network operation simulation tool, pro

Enterprises are becoming more and more demanding on the network, in order to ensure the high availability of the network, sometimes want to provide equipment, modules and link redundancy in the network. However, in the two-tier network, redundant links may lead to switching loops, allowing broadcast packets to cycle e

Today's two network structures are the latest in the industry for image processing problems proposed by the latest structure, the main solution is the Super deep network in training optimization problems encountered. To tell the truth, both models are not mathematically complex in themselves, but it does have a very good effect in combat (the deep residual network
