Tencent Cloud Global Application Acceleration GAAP: A Hard Core Guide to Completely Solve Cross-Border Network "Card, Slow and Broken"

Today, when overseas businesses are blooming everywhere, many companies are facing a headache "ultimate problem":

Cross-border network delays.

You may run very fast during the domestic test, but as soon as overseas users visit, or domestic employees need to log in to overseas business systems, various problems will follow: game players frequently drop lines, online education video cards become slides, and cross-border e-commerce orders keep turning around......

Many people's first reaction is: "add bandwidth! Buy high defense!" But the actual effect is often that money is thrown in and the business is still stuck. In fact, this is not a question of whether the bandwidth is enough, but the natural "road conditions" of public network cross-border transmission are too poor.

Today, let's talk about how to break this deadlock and dismantle how Tengxun Cloud's Global Application Acceleration Platform (GAAP) turns the "muddy mountain road" of the multinational network into a "highway" through a set of "dimension reduction strike" programs.

1. cross-border network, where exactly is the card?

To solve the problem, we must first know the cause. Why are transnational networks so unstable?

The core reason is

Uncontrollability of public network transmission

. When ordinary Internet traffic is transmitted across borders, it needs to pass through countless public routing nodes and also through the export of extremely crowded international submarine cables. It's like driving an ordinary car in the morning rush hour, not only waiting for traffic lights frequently, but also squeezing the most congested cross-sea bridge.

In this process, the three major killers follow:

High latency (Latency): The longer the distance, the longer the fiber transmission time. If the intermediate route goes around the long way, the delay will soar.

High packet loss (Packet Loss): When the public network is congested, the data packet is lost directly like a crowded bus. Once the packet is lost, the TCP protocol will require retransmission, which will enlarge the sense of Caton exponentially.

Jitter (Jitter): The previous data packet took 100 milliseconds, the latter data packet took 300 milliseconds, the network was fast and slow, and voice and video directly changed or stuck.

In the face of such physical injuries, the traditional CDN (content delivery network) is often powerless in the face of dynamic interactions (such as login, order placing, real-time API call, game match-up), because CDN is good at caching static pictures and videos and has nothing to do with "live data.

2. Tengxun Cloud GAAP: Open a "Dedicated VIP Channel" for Cross-border Traffic"

The core logic of Tengxun Cloud GAAP is actually very simple:

Since the public network is unreliable, then we will build a dedicated highway, take over the public network traffic and run on our private highway.

Simply put, its workflow can be divided into three steps:

Nearby access: Overseas users or domestic offices are connected to the nearest Tencent Cloud GAAP access node through the public network. Because the distance is extremely short, this section of public network access is very smooth.

High-speed access: traffic enters the access node

After that, immediately switch to Tencent Cloud's global compliance line intranet (highway channel). This intranet does not go through the public network, there is no congestion, directly all the way to the source node where the target server is located.

Secure back-to-origin: The origin node securely delivers data to the real server of the enterprise.

Through this way of "running on the public network at both ends and running on the special line in the middle", GAAP perfectly avoids the most blocked "intestinal obstruction" at the public network outlet ".

3. Live View: What on earth makes GAAP so fast?

If you just buy a dedicated line, then many big factories can do it. Why can Tencent Cloud GAAP achieve "fast and stable"? This benefits from several hard core black technologies at the bottom:

1. Intelligent routing and "traffic commander"

Network conditions are rapidly changing, what if the submarine cable is broken? GAAP has an extremely smart intelligent routing system. It is like a traffic commander with a God perspective, dialing every moment to measure the health of global nodes. Once the line is found to be at risk of congestion, it can automatically switch traffic to the B line in milliseconds. For the user, it is completely done.

Zero awareness, seamless switching

.

2. Self-developed transmission protocol optimization ("anti-shake" artifact for long-distance transmission)

TCP protocol is a very conservative protocol. Once it finds a little trouble (packet loss) in the network, it will actively slow down. GAAP uses Tencent's self-developed transmission optimization algorithm (similar to an efficient congestion control protocol) within the leased line.

For example, even in the extreme environment where the public network is extremely harsh and the packet loss rate is as high as 50%, GAAP can still ensure that the application layer is almost "not stuck" through forward error correction and intelligent retransmission ". This is a life-saving cure for gaming and audio and video businesses.

3. A global network to support "many to many"

Many traditional dedicated lines are point-to-point (such as Shenzhen to Hong Kong). But if your business is globally distributed, point-to-point is not only costly, but also extremely complex to configure. GAAP implements "one global network". You only need to configure one access group to allow users in North America, Europe and Southeast Asia to access your domestic (or overseas) source station through the nearest node.

4. industry combat: which scenarios can not be separated from GAAP?

Let's take a look at how GAAP can help enterprises "change their lives against the weather" in the actual business scene.

Scene 1: Global Same Service Game (Not Dropped Is the Hard Truth)

For competitive games at sea, the delay of 50ms and the delay of 200ms are completely two worlds. The most intolerable thing for players is to delay their skills and teleport.

Pain point: Southeast Asian players need to connect to servers located in Hong Kong, China. The cross-country public network has a large jitter and frequently drops off lines during the golden period at night.

GAAP Efficacy: Gaming vendors deploy GAAP access nodes in Vietnam, Thailand, and Singapore. Player traffic enters Tencent's cloud intranet nearby and goes directly to Hong Kong through a dedicated line.

Source station. The average delay dropped by more than 40%, and the packet loss rate basically dropped to 0. Players will no longer make one-star bad comments in the comment area due to network problems.

Scenario 2: Cross-border Office and ERP System (Farewell to Web Circles)

Many multinational enterprises and foreign trade companies have their headquarters in China, but there are a large number of branches or supply chain partners overseas. Everyone needs to log into the ERP, OA or CRM system of the headquarters frequently.

Pain points: overseas employees often feedback "unable to open the web page", "report submission failure", "attachment download slow to crash".

GAAP efficacy: After GAAP is configured, access requests from overseas employees are packaged into dedicated lines. Not only do web pages open in seconds, but the transmission speed of large files has also increased several times, and the communication cost of cross-border collaboration has been halved directly.

Scenario 3: Cross-border e-commerce and cross-border finance (keep every order)

In the field of e-commerce, one more second delay will lead to the loss of a large number of impulsive consumers. In the financial industry, the refresh rate of market data determines the success or failure of the transaction.

Pain point: when engaging in large-scale promotion activities, overseas users are stuck on the payment page due to network Catton, and finally give up shopping carts directly.

GAAP efficacy: dynamic API requests (such as login, shopping cart, payment) are accelerated by GAAP, and static images go through traditional CDN. The combination of dynamic and static brings overseas users a silky experience like local shopping.

5. Pit Avoidance Guide: How to Choose GAAP, AIA and Traditional CDN?

Many people see a bunch of network products in the console of tengxunyun, which makes it easy to make choices difficult. Here use the vernacular to help you sort out:

Product

Core Competencies

Applicable Scenarios

How do you choose?

CDN (Content Delivery)

Cache static resources (images, small videos, static web pages)

Website image loading, audio and video on demand

As long as it is static and does not need to change frequently, CDN is preferred.

AIA (Anycast Elastic IP)

Use Tencent cloud renbo technology to enter Tencent intranet nearby at the public network stage.

Game hall login, single-point to single-point global high-quality public network access

Suitable for scenarios such as high-definition live broadcast and game login that require a single compliant IP to cover the world.

GAAP (Application Acceleration)

4-layer/7-layer dedicated line acceleration, providing global many-to-many compliant dedicated line channels

Cross-border ERP, global same-service games, cross-border API calls, financial transactions.

As long as it involves cross-border, cross-regional, and extremely sensitive to delay and packet loss dynamic interactive business, close your eyes and choose GAAP.

6. summary: under the sea outlet, don't let the network become a drag for business.

Now the Internet has passed the era of "grass and brute growth". Users are becoming more and more selective and have a poor experience. Users turn their heads and go to their competitors. Network stability is no longer just a KPI for the technical department, but the underlying infrastructure that directly determines the life and death of the business.

The most impressive thing about Tencent Cloud GAAP is that it combines complex global network topologies, compliance line procurement, intelligent routing algorithms, and the entire

The department is packaged into an "out-of-the-box" cloud service. Enterprises do not need to argue with operators in various countries, nor do they need to buy expensive hardware. With a few clicks of the mouse on the console, they can build a dedicated network channel covering the world within a few minutes.

If your sailing business is suffering from online Caton, try GAAP. Let a professional team to repair the road, you only need to be responsible for driving the car very fast on the highway, that's enough.
