Technological competitiveness

Precise scheduling system

• To improve the accuracy of scheduling , Alibaba cloud CDN Do the following optimization .
  • Constantly updated accuracy IP database ：IP The role of the database is in the user's DNS The parsing request was forwarded to CDN When dispatching the system , The dispatching system will determine the user's region and the operator's ownership , In this way, users can be assigned to the same operators with nearby access CDN node . To make sure IP The data in the database is up to date , The database is constantly updated .
  • Provide HTTPDNS service （ Client compatibility is required ）： use HTTPDNS This technology allows the user terminal to bypass the operator's local DNS, Direct adoption HTTP Protocol to access the scheduling system , The best access node to request the domain name to be accessed , This can be avoided DNS Business security problems caused by hijacking .
  • Node data analysis ：CDN The scheduling system analyzes the health status of all nodes and links in the whole cache system in real time through the link state system , Choose the best access node for users , To avoid the impact of poor quality of access nodes on the user experience .
  • Content based scheduling , Improve access hit rate ： It is often used in two application scenarios: large file download and video on demand 302 Scheduling is a content-based scheduling technology ,302 Scheduling is a central scheduling scheme , When a user requests a resource , After completing the domain name DNS After analysis , The user request will first access the central dispatching system , Then the central scheduling system will analyze the content that the user requests to access , Re pass 302 The best access node is assigned to users by redirection .
• Functional advantages ： The scheduling system includes offline Planning （ Predict and schedule according to the trend of historical traffic ） And real-time scheduling （ Carry out traffic planning according to the characteristics of sudden business ）.
• Functional effect ： Through accurate self-developed scheduling system ,CDN The platform can perceive the health status of each edge node in real time , So as to allocate the best access node for users .

Intelligent cache system

• Precise caching ： Using intelligent object heat Algorithm , multistage 、 Hierarchical cache hotspot resources , Achieve accurate and accelerated resources .
• Cache ： High performance cache Cache The system design , Balanced use CPU Multi core processing power , Use and control memory efficiently and reasonably , Maximize SSD IOPS And huff and puff .
• High speed reading and writing ： Each node has a high-speed read-write SSD SSD Storage , coordination SSD Ability to speed up , Greatly reduce the waiting time for users to access , Improve availability .
• Efficient return to source ： Provide Failover Retry mechanism , Ensure efficient source return and information synchronization .

Efficient transmission protocol

• Support Quic agreement ：Quic It's based on UDP Next generation Internet transport layer protocol , And integrated TCP、TLS、HTTP/2 And so on , It can effectively meet the current needs of the transport layer and application layer , Including security 、 Low latency 、 Handle more connections, etc .
• Since the research TCP Protocol stack algorithm ： By adjusting the congestion algorithm 、 Packet loss detection algorithm , Yes TCP The performance of the protocol has been greatly improved , The transmission performance is significantly improved .

Reliable security protection capability

Alibaba cloud CDN Through reliable safety measures , Help you avoid security risks in your business .

• Anti theft chain ： Users can choose general Referer、UA、URL、IP And so on , It can also be used. EdgeScript To customize the authentication method , To prevent the source site resources from being stolen ; Support remote authentication function to realize secondary authentication .
• DNS Anti hijacking ：HTTPDNS engineering service HTTP Protocol access to alicloud server , Get domain name resolution results , Bypass the operator's Local DNS, Avoid domain hijacking .
• HTTPS Transmission encryption ： Support the adoption of TLS Protocol to encrypt HTTP Content of agreement , Prevent plaintext data from being exposed to the Internet , And you can set TLS1.3、HSTS、keyless And other advanced functions .
• Source protection ： Alibaba cloud CDN The product itself has certain safety protection ability , You can also configure SCDN Products to provide stronger safety protection capabilities .
• Origin reliability ： The primary and standby source stations can be configured , Alibaba cloud CDN It can continuously monitor the status of the primary and standby source stations , When the primary station fails, it can be switched to the standby station in time .
