Do not make the router "black back" for your internet behavior"

Vrouters are getting worse

The bandwidth is often insufficient; the network is really useless, and the network is often disconnected from the card network; how can the router not play a more role. In various forums, websites, and friends around you, you can always hear network management complaints, criticize vrouters based on the situation, or say that vrouters are not easy to replace. In short, there are various sayings. In fact, the cause of network problems such as insufficient bandwidth, network disconnection, and unstable card network is not just a router problem.

"The quality of a router" is indeed very important, but the author believes that the impact of "poor Router" on the enterprise network is more complicated and chaotic.Online behavior. Network administrators often complain about network instability, insufficient bandwidth, and many other problems. In addition to a few hardware-based reasons, the biggest problem is the lack of diversified online behavior management. Simply put, it is incorrect to say that the router does not affect the network. In fact, the router is carrying a "black pot" for excessive Internet access ".

The router carries a "black box" for surfing the internet, which may be due to the following reasons:

First, the Internet is too messy and does not go through different ports. Many applications such as web games, online audio/video sharing websites, and webpage IM all go through port HTTP80, even P2P software also uses port 80 to avoid blocking. In the face of these unrecognized network applications, of course, it is impossible to manage them.

Second, the Internet habits of enterprise staff are different. Some people watch Web pages, watch Web Video, and use P2P to download files. Some users only use real-time communication software or write blogs, some people always drive P2P. It is not applicable to planning networks by using cooperative IP addresses or using the same management standards. Therefore, full online behavior management cannot be implemented. Because vro management does not achieve the management effect, many people point their finger at the vro and let it carry an inexplicable "black pot ".

"Popular routing traffic behavior management" is a popular concept recently. It is understood that this concept is based on years of network technology R & D experience, the application-oriented function based on Packet identification is developed. network administrators can more accurately manage internet behavior and limited network bandwidth with various applications, so that network resources can be used to the maximum extent possible, improve operational efficiency. I believe that if popular routes are based on application orientation and achieve the most meticulous internet behavior and bandwidth management, this "black box" backed by disorganized online behaviors can be easily dumped. For this reason, I have made in-depth research on popular routes.

For different online Application behaviors, popular routes can be divided into four main functions: L7 Application Blocking, L7 VIP Channel, and L7 Application Binding) and L7 QoS bandwidth management.

First, the network in enterprise work is filled with various network applications, such as stock trading, Video watching, IM chat, P2P download, VOIP Business Negotiation, remote file transfer, etc, most work-related or unrelated applications may use the same service port. If applications unrelated to work are too popular, they will not only affect personal work efficiency, but also lead to adverse factors such as slow network speeds, security attacks, and insufficient bandwidth. If it is not well managed, the router may carry a "black pot" for these problems ". Popular routing can identify application services and block (or allow) application use, such as blocking instant messaging, BT, YouTube, and face book. Because it is based on Packet identification, even if different applications use the same service port, it can effectively block applications unrelated to work while opening the applications required for work, this increases office efficiency.

Second, the enterprise's normal network applications will also be prioritized as needed, such as extremely important video conferences, VOIP business communication for major customers, and timely acquisition of network data by senior managers, both must ensure their good bandwidth and stability. In these cases, popular routes can separately set VIP applications, VIP objects (for example, general managers), or both (for example, the general manager is only VIP when opening the webpage ). In addition, when the object is set to VIP, it can enjoy the highest priority of bandwidth usage, which is not subject to QoS Control and the bandwidth used is not limited. In this way, popular routing can give priority to the use of bandwidth for VIP users and application services, so that it will not be smooth or even unavailable because other application services occupy the bandwidth.

Once again, it is common for commercial and school authorities to connect multiple Internet lines at the same time for bandwidth increase and load balancing. However, if the line is not efficient and the utilization rate is low, even if there are more lines, you may feel problems such as the network card and slow speed. This may also be counted on the router head, and added a large "black pot" to it ". In this case, you need to bind a specific application based on the characteristics of the line. Popular routes allow the application to be allocated different external lines, and important applications are bound to a leased line with good online quality, for example, a CRM Customer Relationship Management System that is critical to an enterprise can be bound to the most stable fiber optic cable, while a general network browsing can be concentrated on the ADSL line, even accidental disconnection does not affect enterprise operations.

Finally, when the network bandwidth is insufficient, the Internet may be interrupted. You can view the bandwidth used by the application defined by the Service port, but you cannot see that the bandwidth is unreasonable. In this case, do not mention the router problem. What the network administrator needs to do is to separate unnecessary application services from the service port for bandwidth restrictions, and implement bandwidth protection for truly important applications. Popular routing is based on application identification, allowing network administrators to limit and guarantee the bandwidth of application services. For example, you can limit the download bandwidth of web videos and ensure the bandwidth of general web browsing, so that both web browsing and web video are smooth.

With the increasing diversity of network applications, enterprises should not add lines, increase bandwidth, or blame vrouters for being ineffective. Therefore, they should conduct targeted management and guidance. From the above functional description, we can see that the popular routes of xiaonuo can effectively meet these internet behavior management needs, the bandwidth is not enough, but want to ensure that important applications and other needs, based on application-oriented, achieve the most meticulous online behavior and bandwidth management.

The "black box" behind the internet behavior of the router should be blocked. through effective means, you can effectively control disorganized network applications, and your network can experience the "Flying feeling ".
