Overview

What Is a Central Network?

Relying on the cloud backbone network, Central Network allows you to easily build a reliable, intelligent enterprise-grade network and manage global network resources on premises and on the cloud. By building a central network, you can enable communications between enterprise routers, as well as between enterprise routers and your on-premises data center, in the same region or different regions.

Application Scenarios

• Cross-region communication on the cloud: 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.

• Communication between on-premises data centers and the cloud across regions: Enterprise routers and global DC gateways are added to a central network as attachments, so that on-premises data centers can access the cloud over the cloud backbone network.

• Global network: By flexibly changing the central network policies, you can build a global network more conveniently.

Process for Using a Central Network to Manage Network Resources

Figure 3 shows the process of configuring a central network to manage global network resources.
