Network Interoperability Shi Policy Routing method

With the popularization of information life, online video games and the content of video-on-demand more and more rich, more and more attractive, user groups developed rapidly, forming a strong consumer power. According to statistics, the biggest consumer to the Internet Café is online games and video on demand, download services.

Assembled in the Internet café, different users will choose different online games or download services, it is because different services are often provided through the servers of different operators, it is often the case that Internet cafes using telecommunication networks are unable or difficult to access netcom, or when accessing telecom servers on Unicom's network, Connection speed is obviously affected by the limitations of the network. Users who go to Internet cafes tend not to understand why this happens, demand is not met will naturally complain, resulting in customer dissatisfaction and even loss, so that the Internet café owners and network management are very headache, in a long time, such a solution to the problem of the discussion was once active in China's several major Internet cafes technology forum.

Barriers to interoperability, Internet cafes

The following is a simple test, first to understand the different operators or different regions of the network interoperability between the response time, so as to speculate on the impact of Internet bar connection speed.

The network management can ping this kind of work which is used to test the net reaction, under DOS instruction Ping a familiar station to test the speed. According to the Taiwan router Manufacturing Enterprise Knight Technology in Shenzhen to do the test to see, from telecommunications to railcom, there may be ping impassability, and netcom on the telecommunications and telecommunications between netcom, although generally can ping, but there will be a difference of 600ms situation. To look at the interoperability of remote servers to ping Heilongjiang Telecom and Netcom's DNS as an example, the different operators of the server ping response to the need for more than 600ms, and we ping the U.S. website, generally only about 200ms below. It is obvious that the interconnection between different operators will make many operations slow or even not, and have a great impact.

Under such circumstances, the inconvenience caused by telecommunication operators ' network interoperability is highlighted, single line, single operator access to the form of access is clearly unable to meet customer requirements, users in this Internet café not connected to the required server, or connection speed is very slow, it will naturally flow to other Internet cafes with access to the required operators. Internet cafes to retain customers, open up new sources, you must consider the allocation of multiple operators to access the way. Internet cafes or businesses that use multiple WAN routers, because of the need for line backups, tend to apply for multiple network operators ' lines, such as ADSL broadband services using China Telecom and Unicom. In this way, when a network operator drops the line, at least another line can withstand. On the other hand, multi-wan routers typically provide services and provide link backup by providing a dual-line load-balancing approach, although the speed can be significantly improved, but if not some game and download services to configure and schedule the flow, or the same will occur due to the speed of the Internet exchange rate is affected by the situation.

The author from Guangzhou several internet cafes to understand that due to the Internet exchange rate caused by the impact of the problem, the practice of some network management is to separate several areas of Internet cafes, each introduced a different line. This does allow users with the specified needs to surf at high speed on their chosen networks and servers, but in so doing, different regions cannot share resources and lose the meaning of multiple WAN access, abandoning the load balancing and line backup functions of multiple WAN routers Another approach is to reconfigure the gateway or use gateway switching software to select the appropriate carrier network connection. For this kind of practice, many network management all feel extremely inconvenient, because the reconfiguration of the gateway or the use of Gateway switching software can not be once and for all, this is because the DNS settings need to be fixed, so if you have set up the Netcom's DNS, when switching gateways for telecommunications, or to manually modify DNS for telecommunications, very cumbersome and time-consuming.

Key issues highlighted, Policy Routing solution

How can the router judge which traffic is to telecom, which traffic is to Unicom, let go to see the telecom film server to go Telecom Gateway, to connect the movie server to go unicom gateway? All these problems, prompting the Internet café owners and network management to build a more convenient network, to create a better service environment for consideration, for this reason, network management has summed up two issues-how to achieve without adding external devices in the case of two lines automatically switch? If you do not reset the gateway, how to automatically switch to different operators according to the needs of the game, so that the choice of games and download services can be the best line to start and guarantee the effect?

This time, the choice of a strategic router, will be a very simple and practical solution. It is understood that at present there are a number of strategic routing features of the multi-Wan access router, Taiwan's grand technology is a developer and manufacturing enterprises representative. These products can be combined with different access schemes, only to find out the IP address of different carrier servers, can be through binding protocol or specify the route set way, all network with the machine for automatic analysis, and the analysis to the flow of the corresponding carrier server.

According to Mr. Zhang Jianqing, the engineer of the Nobel technology, Policy routing configuration has two methods to use: one is to use the binding protocol, according to the IP address of the telecommunications server, set their respective operators WAN lines, the second is to use the specified route settings, according to the IP address of the telecommunications server, set the respective operator's external gateway and WAN lines. These two ways can achieve the purpose of Policy routing, the biggest difference is that the general binding way to allow a smaller number of settings, and the use of binding can be allowed to set a larger number of users can choose a method or at the same time with the use. When connecting to a different operator's game or movie server in a connected network through the same router, you can specify that specific applications go to the Internet on a specific WAN port, regulate the flow of different games and movie servers, and make these services available for optimal results. Universal resources can continue to use the load balancing capabilities provided by multiple WAN routers and share bandwidth.

In this way, by simply setting up the router, Internet cafes in different users can freely choose different network games or download services, enjoy flexible, smooth connection, without the need for additional dedicated lines, no hard zoning, no need to constantly configure the gateway or additional installation gateway switching software, to ensure the smooth line of internet cafes, Keep the internet cafes attractive to different customers. In addition, network management can also through monitoring, to understand the connection and flow of the situation, timely response to the emergency situation to deal with.

Conclusion

The problem of broadband Internet interconnection is not quite the same in all parts of the country, at the same time, many special servers in the network usually do access restrictions, resulting in the network is not smooth problem, in a short time is impossible to avoid, and through a policy routing function of the multi-WAN router to implement the boot function, The impact of Internet connectivity barriers among telecom operators can be minimized, and in fact, many internet cafes or colleges are doing so now.

The Internet café chooses the router of the strategy routing function to set up the Internet Bar Network, so as to offer the game and service support of different telecommunication operation freely, can create a better service environment for the customer, from the actual to solve the user's request, effectively enhance the quality and attraction of the Internet bar.
