Integrated Content Delivery Network

Through multiple technologies such as separation of dynamic content from static content, multi-level caching, intelligent routing, protocol optimization and link optimization, eSurfing Cloud integrated content delivery network (ICDN) achieves nearby delivery of static content and rapid retrieval of dynamic content. As a result, it solves the issue of slow response caused by network congestion, link jitter and sudden traffic increase and significantly improves the performance of the origin.

Professional 丨One-stop After-sales Guarantee

One-to-one dedicated project manager, 7*24h technical support, localized sales network system in 31 provinces, providing refined customer service "at home".

Features
Multi-level Caching The product supports caching according to the cache header time of the source site and customizes caching rules based on the file type and directory to meet diversified caching requirements of customers. Multi-level caching: Edge and parent layer multi-level caching. When the edge does not hit the cache, the edge requests the parent layer for cache resources, which increases the cache hit ratio. Different domain names with the same content share the cache to reduce retrieval and increase the hit ratio.
Dynamic Acceleration Nodes perform detection in real time to obtain the current network conditions and report the information to the central server as the basis of intelligent routing. The real-time detection results between accelerated nodes and the link algorithm developed by eSurfing Cloud are used to obtain efficient transmission paths and guarantee the effect of dynamic content retrieval.
Transmission Optimization The product supports long connection holding and link reuse to save the three-way handshake time and improve the access effect. The intelligent compression technology is used to optimize transmitted content and improve the transmission efficiency.
Multi-protocol Processing All nodes on the platform support IPV4/IPV6 dual-stack protocol and IPv6 access can be upgraded through one click. Through the protocol optimization technology, the product intelligently judges the network conditions of users and optimizes the transmission window to achieve rapid content transmission and improve user experience. The product supports HTTP, HTTPS, HTTP2.0, WebSocket and QUIC.
Access Control The product supports restricting the access frequency based on IP, directory and file type and denies attacks such as malicious access. The product supports restricting the total bandwidth of the customer and controls the bandwidth cost within the budget. The product supports the Refer anti-leech, IP blacklist and whitelist, UA blacklist and whitelist and URI blacklist and whitelist to avoid unnecessary bandwidth and cost and protect content copyrights.
Retrieval Configuration The product supports access to special ports. The product supports policies such as multi-IP-address polling and mutual backup, preferential retrieval, hash retrieval and retrieval by region, operator and IP.
Refresh and Prefetch After the content of the source site is updated, a refresh request can be submitted to force the cache of CDN nodes to expire so that users can obtain new content when they access data. After the content of the source site is updated, a prefetch request can be submitted to cache new content of the source site to CDN nodes so that users can obtain the new content when they access data.
Portal Client Console The product supports self-service configuration. Users can manage the configuration acceleration content. Statistical analysis: The product provides a visual display platform, which can clearly and intuitively display usage analysis information such as bandwidth, traffic, number of requests, QPS, hit ratio and status code, as well as user access data, so that customers can know their service information.

Scenarios

< >
  • Dynamic Content Acceleration
  • Global Acceleration of Dynamic and Static Mixed Sites
  • Upload Acceleration
  • WebSocket Acceleration
  • IPv6 Upgrade Acceleration
Scenario description
  • Dynamic content acceleration is applicable to dynamic service scenarios that require timely and stable data transmission, for example, financial payment, e-commerce trading, game competition and online education.
Issues solved and advantages
  • The product selects the optimal retrieval path through technologies such as real-time path detection and intelligent routing and achieves fast retrieval through technologies such as protocol optimization and content optimization. As a result, it significantly reduces the user access delay, solves issues such as slow loading of dynamic content and intermittent stop of operation and significantly improves user experience.
