Background and demand

As a key component of carrier network infrastructure, DNS serves hundreds of millions of users. The efficiency, accuracy, and security of domain name resolution directly affect the secure and stable operation of the network and users' Internet access experience. The challenges are:

01: How to ensure the Internet experience of massive users
High-speed and accurate response to user access requests, including avoiding unnecessary inter-network access, remote access, etc

02: How do I keep the system highly available
Reasonable design and deployment of DNS service system architecture; It can effectively defend against various types of DNS attacks and carry several times the normal service processing capability.

03: How to flexibly adapt to the growth of users and changes in business requirements
High-performance DNS dedicated device and highly reliable system architecture. Reasonable and flexible expansion capabilities to support rapid business growth and changes.
