DCDN

A content delivery acceleration service, based on Alibaba Cloud's CDN to accelerate content delivery for hybrid sites, dynamic sites, and applications.

Benefits

Accessibility
Easy acceleration for the entire site without the need to divide static and dynamic content.
Global Acceleration
Provides more than 1,300 nodes covering six continents and redirects user requests to the nearest node for high-performance data transmission through real-time routing and stack optimization.
Service Reliability
Maximum bandwidth of 90 TB/s for content delivery with 7/24 service support to reduce costs of operations.
Content Security
Full encryption over HTTPS and integrates with multiple types of access controls, to guarantee secure content delivery.

Features

Acceleration

Full site acceleration, static and dynamic content separation, smart routing, stack optimization, data compression and merging, and error code page customization.

Smart Routing

Smart static content caching on edge servers. Hierarchical and distributed caching to reduce loading.

Dynamic and static separation

Custom configurations for accelerating static and dynamic content.

Static Content Caching

Smart static content caching on edge servers. Hierarchical and distributed caching to reduce fetching from the origin.

Intelligent Routing

Real-time link quality detection and origin fetching through the optimal link.

Stack Optimization

Transfer layer and application layer protocol stack optimization for fast and stable data transmission.

Data compression

Data compression before transfer.

High Stability

Full site load balancing with multiple fetching protocols, site monitoring, and error code page customization.

Multiple origin site types

Support for multiple types of origin sites, including public IP addresses, Object Storage Service (OSS), and custom domain names.

Website Monitoring

Support for multiple types of websites, including public IP addresses, Object Storage Service (OSS), and custom domain names.

Origin site monitoring

Monitoring for promptly detecting and preventing access failures.

Wait Mode

Traffic throttling and queuing policies to guarantee the stability of services on origin sites, when the sites experience bursts in traffic.

Auto-reconnect on failover

Dynamic content acceleration with session persistence and re-connection on failover, to ensure high-performance origin fetching and information synchronization.

Response page customization

Response page customization for error codes such as 403, 404, 503, and 504.

Basic protection

Includes anti-leeching, tampering prevention, and access control.

Anti-leech basic

Includes referer and IP address whitelists, and blacklists to prevent leeches.

Anti-leech pro

Includes URL encryption and authentication.

Hijacking and tampering prevention

Includes HTTP DNS hijacking prevention, HTTPS encryption and authentication, and URL encryption and authentication.

Access control

Includes IP address blacklists, region blacklists, and user agent (UA) blacklists.

HTTPS acceleration

Supports certificate-based authentication on clients, free certificates, SSL optimization such as HTTP/2 and SNI, and acceleration schemas without private keys.

HTTP/2

Full link transmission over HTTP/2. Supports header compression, request priority setting, link multiplexing, and server pushes.

Shared IP addresses based on SNI

Access optimization, without restrictions to IP bindings.

Session resumption

Session resumption to reduce the SSL and TLS session negotiation time.

HSTS

Force HTTPS in web browsers to enhance access security.

HTTP and HTTPS redirecting

Redirection of HTTP requests to an HTTPS origin site or redirection of HTTPS requests to an HTTP origin site.

Certificate-based authentication

Certificates provided by the clients are used in mutual authentication to authenticate the server.

Free certificates

Supports free DV and SSL certificates from Symantec, which is a leading SSL and TLS certificate provider.

Flexible management and control

Domain name configuration, billing management, and resource monitoring in the console are used to implement flexible management and control.

Resource monitoring

Monitoring and displaying of the network traffic trends on dashboards.

Domain name management

Simple configuration of domain name-based origin sites, static and dynamic content acceleration rules, and access control.

URL refresh and content pushes

Uses URL refresh to ensure access to the latest content, and the content push function to cache the content updates on nodes to prevent a burst of origin fetch traffic.

Log management

User access log downloading to help website data analysis.

Billing management

Simple modification of billing methods and purchasing of data transfer plans.
