Cloud servers are very popular in recent years, because cloud servers have efficient and flexible computing resources, which are widely used by more and more individuals and enterprises. Looking at the game field, especially in overseas game acceleration, private service construction, remote online and other scenarios, cloud servers are an important choice for many players. Two-way CN2 (also known as CN2 GIA Bidirectional optimization) in the CN2 line is known as the ceiling of the network experience, because of low latency, less packet loss, and strong stability. That in the end two-way CN2 cloud server to play the game is really not card? The following combined with the characteristics of the line, the way players use, the location of the connected game server, the actual bandwidth quality and other aspects of analysis, a deeper level for everyone to answer.

First, it is crucial to understand what a two-way CN2 line is. CN2 is a high-quality BGP backbone network launched by China Telecom, which is divided into CN2 GT (one-way optimization) and CN2 GIA (two-way optimization). The former generally only realizes the optimization of China to overseas, while the latter realizes the optimization of the whole process from China to overseas and overseas to China, with better stability and lower latency. The emergence of two-way CN2 lines is mainly to solve the problems of high delay, high packet loss rate, and unstable backhaul lines in traditional international lines, especially in cross-border access services.

When playing a game, latency is a key factor in determining the game experience. Especially in the first person shooter (FPS), multiplayer online tactical arena (MOBA), fighting and other games that require high reaction time, the network delay directly determines whether the player can smoothly control the character and perform accurate operations. If the player is connected to an overseas game server, such as American service, European service or Japanese service, then the ordinary international export line can hardly provide a satisfactory experience, often accompanied by a delay of more than 100ms, and even a volatility packet loss, which is fatal to the game experience. The use of cloud servers equipped with two-way CN2 lines as transit nodes can greatly optimize this situation, making the interaction between players and overseas servers more smooth, and the delay is stable at the level of tens of milliseconds.

Of course, this is not to say that using a two-way CN2 cloud server to play games will absolutely not occur. The network performance of a cloud server not only depends on whether it is equipped with CN2 lines, but also is affected by many other factors. For example, whether the actual bandwidth is sufficient, whether there is a speed limit, whether the peak time is congested, whether the routing of the machine room is stable, and even the network management strategy of the cloud service provider. Although some small manufacturers promote the support of two-way CN2, there may be bandwidth squeeze at the peak, and there will still be game drop or deadlock. Choosing a regular service provider with good reputation is an important prerequisite for ensuring network quality.

Second, there is the player's own network to consider. For example, the player's local broadband quality, router configuration, whether to use a wired connection, etc., will have an impact on the speed and stability of connecting to the cloud server. Sometimes players use CN2 cloud servers at the same time the local network problems, will also cause the illusion of "server card". Therefore, the two-way CN2 cloud server is good, but it cannot completely replace the optimization and debugging of the local network.

In addition, when using cloud servers to play games, the specific use of the way is also critical. Some players log in to the cloud server directly through the remote desktop and run the game, which has high requirements for the CPU, GPU, memory and other configuration of the cloud host, and the CN2 line does not improve this kind of delay. More players will use the cloud server as a game accelerator or  springboard, which can effectively improve the connection path between overseas servers, improve stability, and reduce latency. And two-way CN2 is the ideal choice to optimize this scenario, enabling a better acceleration experience than ordinary .

Another factor that cannot be ignored is regional differences. The same is the two-way CN2 line, the quality of the export line in different regions may also be different. For example, CN2 GIA nodes in Hong Kong, Los Angeles, Singapore and other places generally perform better, and some less popular regions may still perform poorly even if they are nominal to support bidirectional CN2. This is also one of the reasons why many professional players are more inclined to choose Hong Kong CN2, the United States CN2 GIA cloud server.

Two-way CN2 cloud server game, combined with the above information can be concluded in theory and most practice can effectively reduce the delay, improve the stability of the connection. However, it is also necessary to combine the bandwidth and performance of the cloud server itself, the status of the player's local network, the location of the game server and the use of the method of comprehensive judgment. For players playing overseas games, the two-way CN2 cloud server is still a cost-effective connection optimization solution. Only by choosing high-quality cloud service providers, rationally configuring server resources, and ensuring the stability of the local network, can we maximize the advantages of CN2 GIA and make the game more smooth.
