I am new to the network at a time when knowledge, and sometimes will always be a problem which, it is bridging, the difference between switching and routing, I believe that most of the beginner knowledge of computer networks, netizens and friends will have such a situation. A few days ago a friend ran into a User to make such a question, today I'll take you to understand what is bridging, switching and routing, and for the difference between the three scenarios, and to be a detail.

1, what is the bridge

bridge work in the OSI reference model Network Layer Data Link Layer, is a kind of MAC address as a basis for judging the network is divided into two different physical technology segment, which is widely used among the early computer networks.

We all know that Ethernet is a shared media network transmission technology, this technology, if one computer sends data, when, in the same physical network medium requires a computer to receive, at the receiver After the analy... Read more

This page tools can be used to set the device's network address and account number and other information. In order to ensure that only the device owner to use this management tool page, the device is usually also have a login interface, and only enter the correct user name and password, users can enter the management page.

As early as the beginning of the formation of IPV6 technology, people have begun to IPv4/IPV6 network transition, coexistence, interoperability, and many other aspects of the technology research and feasibility studies, more focused on the underlying network level, how the network from a traditional IPv4 smooth migrate to the ultimate IPV6 network.

When starting the deployment of IPV6 in the data center applications, or build a IPV6 data center, data center construction ideas with other network elements not the same. As the data center is to ultimately provide a comprehensive IPV6 services, should this support IPV6 is a data center's core objectives and the need to be able to provide under current conditions IPv4/IPV6 external full-service.

Current IPV6 Basic application

At present the network IPV6 applications to FTP, WEB services, Video on Demand, file sharing and other service-oriented, these services have certain requirements for network bandwidth, computing on t... Read more
