The broadband of the desktop computer in the family, the mobile phone is too slow to move the Internet. Can you use the mobile phone WiFi to access the Internet on the computer?
This can it help automatically installation?

Virtual router is Virtual Router, which refers to the functional simulation of physical routers in the soft and hardware layer, which is a logical device.
Stherbone virtual router to seek reality, paving the way for the realization of new services in the future. Virtual router is such a new technology that makes it possible for some new Internet Internet services. Through these new services, users can control the performance, Internet address and routing, and network security of the network. Israeli RND Network Corporation is a manufacturer provided from the LAN to the wide area network solution. The company first proposed the concept of virtual routing.
On a physical router, multiple logical virtual routers can be formed. Each virtual router runs its own routing protocol instances alone, and all have their own I/O ports, caches, address space, and space space, address space, address space, address space, address space, address space, address space, address space, address space. Routing tables and network management software. Virtual backbone routers can provide customers with low -cost dedicated backbone network control and safety management functions. The software that controls and manage the virtual routing device is modularly designed. If these software runs on a real, multi -process operating system (such as: UNIX), then it also supports multiple instances, that is, it can support more at the same time to support more at the same time. A virtual router. The process of each virtual router is separated from each other from other routers, and the memory used is also protected by the operating system, which ensures the high degree of security of the data. At the same time, it also eliminates the imperfection of the software module caused by the imperfections of the software module The possibility of collision with other virtual routers.
This -level router When a high -speed SONET/SDH network connection is connected to the group forwarding, it rely on hardware to achieve line -speed performance. For systems that use virtual routing functions, these hardware functions can be logically subdivided; they can also flexibly configure them to a dedicated virtual router. Software modules with virtual routing functions can fully control the physical port and exchange paths that can be sent and received by data groups. The size of the group cache and exchange table of the virtual router, which is limited by the size of its occupied resources, is to ensure that the virtual routers will not affect each other. Virtual routing technology enables each virtual router to perform the routing protocol software (such as: OSPF, BGP) and network management software (such as SNMP or command lines). Therefore, users can independent each virtual router. Monitor and manage. Examples to run the network protocol independently, each virtual router has a completely independent IP address domain, and no conflict will occur with each other. Each virtual router can be managed as a separate entity. The user -based security module provided by it can ensure that all network management functions and information belonging to a virtual router are only open to users with authority. In addition, the packet forwarding path of each virtual router is also independent of each other, which allows administrators to configure performance separately for each virtual router.
In virtual routers, large communication emergencies can only affect this router, without affecting other routers, which provides a guarantee for end users to obtain stable network performance. In addition, the virtual router also provides independent strategies and IETFDS (Internet Task Force Services) capabilities, allowing virtual routers to provide complete customerization services for end users. By configured the I/O port of the virtual router, you can count the receiving packets, so that the amount of data can not exceed the pre -determined protocol; The packets are allocated to different queues to achieve different service quality.
You need to add a wireless network card to the computer, and then set the Internet to share, so that the phone can access the Internet through the computer. In fact, usually everyone buys a router, and then the computer and mobile phones go online through the router. In this way, the mobile phone does not need to turn on the computer when surfing the Internet, which is more flexible and saved.

The wireless router is only tens of dollars
It always drive the computer for mobile phone online, right?
