Overview

Content Acceleration by CDNetworks is designed to deliver unparalleled acceleration and efficient distribution for a broad spectrum of static content. From text and images to webpage components and diverse file downloads such as mobile apps, game packages, software, and hardware drivers, CDNetworks ensures your content is delivered globally in a secure, fast, and stable manner.

Leveraging cutting-edge edge caching technology and intelligent scheduling mechanisms, we guarantee precise content delivery across a globally distributed network of CDN edge servers. This infrastructure enables users to retrieve content from the closest server, significantly boosting access speed across various regions and applications.

CDNetworks boasts a vast global network infrastructure with a robust service network that extends over 70 countries and regions, including more than 2,800 CDN Points of Presence (PoPs) and strong partnerships with over 200 leading service providers. Our total bandwidth capacity reaches an impressive 200 Tbps, ensuring smooth content delivery even during peak traffic hours.

Why Trust CDNetworks CDN

Choosing CDNetworks CDN means you will benefit from comprehensive, high-quality content distribution services covering every aspect of content delivery:

• First Mile Optimization: We implement a variety of origin retrieval strategies, including origin server disaster recovery switching, sequential origin retrieval, and origin load balancing. These strategies significantly reduce the load on your origin servers and enhance their security.
• Middle Mile Optimization: Our advanced cache management and optimization strategies greatly increase access hit rates. Paired with intelligent routing optimization, this reduces transmission times and accelerates content delivery.
• Last Mile Optimization: Utilizing a dynamic intelligent scheduling system, we continuously fine-tune the allocation of edge servers to ensure that every user accesses the most efficient CDN edge server available, thus delivering exceptional access quality consistently, regardless of location.

How Content Acceleration Works

Once a domain is integrated with Content Acceleration (CDN) service, the sequence of events when an end-user initiates a request is depicted below:

Consider a scenario where your domain is test.cdnetworks.com and an end-user requests content like http://test.cdnetworks.com/browse/index.html:

1. End-user queries Local DNS: The user requests the IP address associated with the domain. The Local DNS checks if it has a cached record for test.cdnetworks.com. If it exists, the IP is returned directly; if not, it seeks the domain resolution record from the authoritative DNS.
2. Local DNS queries CDNetworks’ scheduling system: Your authoritative DNS settings should configure the domain test.cdnetworks.com to point to a CNAME provided by the CDN. For instance, CDNetworks uses a consistent CNAME format such as *.wcdnga.com. When the Local DNS does not have this CNAME cached, the authoritative DNS returns this CNAME record, which then directs the Local DNS to query the CDN’s scheduling system. This guides the request to the nearest CDN edge server based on DNS routing.
3. Obtaining the CDN Edge Server IP: The CDN scheduling system selects the most appropriate CDN edge server based on geographic proximity, network conditions, and load balancing strategies. It then assigns the best edge server’s IP address, which is then returned to the Local DNS.
4. Returning the Optimal Node IP Address: The Local DNS forwards the IP address of the optimal CDN edge server to the end-user.
5. User requests the CDN edge server: The end-user sends a request for the content to the IP of the best CDN edge server.
6. Handling Cache Miss: If this is the first request for the content or if the cached content has expired, a cache miss occurs. The CDN edge server then retrieves the content from the origin server.
7. Content Response & Caching: The CDN edge server delivers the content to the end-user and stores it in the cache for future requests.

This process ensures that CDN significantly enhances content distribution, improving the overall access experience for end-users.

Best Practice Scenarios

The Content Acceleration is specifically tailored for files that remain unchanged across requests, encompassing images, videos, webpage components (e.g. HTML, CSS and JavaScript), software installation packages, APK files, and others. At the heart of this service is caching technology, which duplicates static content from your servers to CDNetworks CDN edge cache. This allows users to access content from the nearest CDN edge server, eliminating the need to fetch data from the origin server, thereby speeding up access and reducing the load on the origin server.
