Cloud Enterprise Network (CEN) is an enterprise-class network that can interconnect the network resources of Alibaba Cloud around the world. CEN can also be used to interconnect the local data centers that are already connected to the Alibaba Cloud network. CEN validates the IP address ranges of the connected networks and ensures that the IP address ranges do not overlap. Additionally, CEN automatically recognizes adaptive routing-forwarding and distribution across multiple nodes through controllers, which enhances network performance through fast routing convergence.
Low latency and high speed
CEN provides low-latency and high-speed network transmission. The maximum access rate between local networks can reach the port forwarding rate of the gateway device. From the perspective of global network communication, the overall latency of CEN is significantly lower compared with the public network.
Nearby access and shortest-path connection
Multiple access points are deployed in more than 60 regions around the world to facilitate global access to Alibaba Cloud, enabling traffic to travel through a responsive and latency-free network. The shortest-path algorithm of CEN recognizes efficient connections between local data centers and the Alibaba Cloud network resources.
Redundancy and disaster recovery
CEN features high availability and network redundancy. Multiple redundant links are available between any two access points. If a link is interrupted, CEN can ensure the service continuity without network jitter or interruptions.
Network monitoring is systematic. CEN can automatically detect any route conflicts caused by system changes to ensure the stability of the network.
