Anycast Internet Acceleration

A dynamic acceleration network with global coverage that makes Internet access more stable and reliable with lower latency


Tencent Cloud Anycast Internet Acceleration (AIA) is a dynamic acceleration network with global coverage that can greatly improve the Internet access experience of your business. Unlike other application-layer acceleration services, AIA can optimize IP transfer quality, enable access from the nearest entry node and reduce jitter and packet loss of network transfer, thereby improving service quality of in-cloud applications, expanding service scope and simplifying backend deployment.


Low Latency

AIA uses the Anycast method to simultaneously publish the IP to multiple regions. The request packet will reach the optimal IP publishing region according to the transfer protocol. The packet will prioritize entering Tencent Cloud before reaching the server through Tencent Cloud's private Direct Connect line, helping avoid Internet congestion and reduce latency.

High Reliability

Internet transfers can be unreliable; if a line interruption of the ISP leads to inability to access the Internet, users will have no choice but to wait for recovery to complete the transfers. With the aid of AIA, multiple paths and entries are made possible by Tencent Cloud's private networks, the ISP's backbone networks and Tencent Cloud's POPs, thus eliminating the potential for connection failures caused by single-region or single-line network outages and enhancing network stability.

Reduced Jitter

Unstable performance of the Internet link can lead to an unstable service experience, such as network jitter caused by cross-ISP or cross-border connection issues. In contrast, Direct Connect transfer offers stable performance. AIA allows the request to access the nearest Tencent Cloud node and get transferred through Tencent Cloud's private Direct Connect line across regions, which perfectly resolves any issues with Internet jitter.

Simplified Deployment

Implementing services that are accessed by end users in many different regions can be cumbersome as servers have to be deployed in each region, DNS has to be properly configured to enable load balancing and IPs vary in different regions. AIA eliminates the need to configure IPs for each region, clearing up the trouble caused by geographic dispersion at the IP level. In addition, only one set of logics need to be maintained on the backend where the requests from different regions are accelerated to reach the backend servers through the Direct Connect line.

Global Load Balancing

AIA uses the Anycast addressing method to simultaneously publish the IP to multiple regions. The request packet will reach the optimal IP publishing region (usually the nearest region) according to the transfer protocol, which achieves global load balancing. Additionally, in the case of a traffic-based attack, the cross-region publishing of IPs helps distribute the attacking traffic.

Ease of Use

AIA is compatible with common IP operations, allowing you to purchase just one accelerating elastic public IP and lowering the threshold for use. It supports self-service Internet bandwidth limiting, making it easy to configure upper limits for bandwidth based on cost or server processing speed. In addition, it supports traffic monitoring for backtracking and analysis as well as binding and unbinding for easier backend resource changes.


AIA can help anycast an elastic public IP to multiple regions to achieve the following functions:
Cross-region Unified Servers

The requests and responses of end users can be accessed from the nearest Tencent Cloud node, with only one set of backend service cluster, database and storage nodes requiring deployment. Using traditional methods, one set of cluster or storage nodes are deployed in each region to serve the nearby end users, but with IP anycasting, the same backend services can cover multiple regions through Tencent Cloud's private Direct Connect line.


Gaming Acceleration

An Anycast IP can serve as a gaming accelerator. A gaming request enters Tencent Cloud through the nearest node and then reaches the game server through Tencent Cloud's private Direct Connect line, significantly shortening the Internet path distance and reduces latency, jitter and packet loss. In addition, compared with traditional acceleration services, AIA simplifies DNS deployment as IP entries do not require deployment of additional traffic receiving devices and IPs do not need to be geographically differentiated.

Live Video Interaction

Clear video and voice have to be relayed without delay during cross-region transfer of live streaming content, meaning the live streaming platform must build a dedicated network and access points covering multiple regions. With the help of AIA, the platform can directly utilize Tencent Cloud's backbone networks and POPs to serve live streaming users without the need to set up a dedicated network.

Financial Services

The securities industry requires high real-time performance, making unstable Internet transfers completely unsatisfactory. The access layer of an application in this field can be bound to an Anycast IP for multi-region coverage, made possible by private network transfer on Tencent Cloud's backbone networks. Further, AIA enables the use of the same IP for multiple regions, simplifying the paperwork for IP-related approvals such as ICP license filing and registration with financial regulatory authorities.

Security Services

Security cleansing service providers, gaming platforms and large-scale website applications are often faced with various traffic-based attacks such as SYN floods and ICMP floods. A common public IP is published in one single region, so all the attacking traffic is concentrated in the same entry. With AIA, the IP is published simultaneously in multiple regions, and the attacking traffic can be diverted to multiple entries for absorption without the need to modify the DNS configuration.
