Application Scenarios

Central Network Application Scenarios

A central network enables enterprise routers in different regions to communicate with each other. It also enables communication between enterprise routers and on-premises data centers, no matter whether they are in the same region or different regions.

• Connecting VPCs in different regions by attaching them to enterprise routers in the corresponding regions

  Enterprise routers in different regions are added to a central network as attachments so that resources in these regions can communicate with each other over one network.

• Connecting on-premises data centers to VPCs in different regions by attaching them to enterprise routers in the corresponding regions

  Enterprise routers and global DC gateways are added to a central network as attachments. In this way, multiple VPCs can communicate with on-premises data centers across regions.

• By flexibly changing the central network policies, you can set up a global network more conveniently.
