With the hundred trillion, gigabit, or even the gradual popularization of the LAN, broadband metropolitan area Network, and even wide range of broadband network applications, whether it is intranet, Extranet, also the Community Intelligent Network,

When connecting a computer to a switch, it may take 30 seconds or more for the computer to communicate with the network. If you are in a hurry to use, 30 seconds of waiting is enough to make you feel very long. Let's see how we can speed up the port

Now many units have installed the program-controlled switchboard, and the most important part of the program-controlled switchboard is integrated circuit (IC). IC anti-interference ability is low, even if from the line induction Lightning

Now the enterprise network is often used in the construction of OSPF, this agreement to do some elaboration. OSPF is called Open Shortest Path priority protocol, and all device vendors support a protocol which belongs to link state routing protocol,

The development process of exchange technology Ethernet switch, English for switch, also someone translates as switching, exchanger or switched hub. We first review the development of the local area network. The combination of computer technology

Customer Requirements: Dual WAN ports, support line load balancing (such as VLAN 2,3,4,5,52,54 users normally go to the fiber-optic Internet, when the fiber is broken off, all go ADSL Internet (Backup function), the fiber back to normal, the users

Wi-Fi development has three major stumbling blocks: security, roaming and coverage. And safety is the first one, in the Gao. How to solve the security problem, is always restricting Wi-Fi users, especially enterprise users large-scale application of

To see this topic, perhaps readers are dismissive: What are the networking options for the switch? It's all about connecting it to the user's computer. Of course, that is for switches in the entire network location, some high-level switches such as

In the long run, bandwidth itself is always inadequate. The smart "devices" behind the network infrastructure--switches and routers--must assume the difficult task of being intelligent to keep pace with bandwidth requirements. Applications like

1, the problem description: We have a CPE MP1803 router as a customer's CE router, the PC after the IGMP report, our router will be in the IGMP table to write the multicast group, but the customer said that the upstream of the PE device does not

Remote monitoring refers to the technology of monitoring and controlling the target device (server side) remotely by a device (client) through remote monitoring software in the network. The operator can monitor the screen display of the controlled

Frequent information disclosure events make the enterprise and the industry more concerned about the risk of intranet security. This article is divided into four aspects to discuss intranet security, including intranet security technology selection,

Used to use routers and hubs in the network, and now many networks use switches, how to face the challenges of routing networks and switching technology?At present, the switch in the network market occupies a dominant position, the reason is: the

How to create a "clean" network environment, not only in the use of how powerful security equipment, that is only a symptom and not the root causes, the right approach should be to create a new security infrastructure to build a new network order.
