Technical Overview of IP RAN Virtual Cluster Access

Technical Overview of IP RAN Virtual Cluster Access

IPRAN virtual cluster access centralizes control planes to form a unified virtual control plane on a virtualized network. Multiple network devices become a device on the control plane. IPRAN virtual cluster access is deployed on the access ring that consists of CSGs and AGGs, as shown in Figure 2-3. Virtual cluster access nodes have two roles: master and AP.

Master: a controller that performs centralized route calculations, service provisioning, and traffic control for access points (APs). The AGGs shown in Figure 2-3 are masters. Masters are classified as primary or secondary masters.

AP: a client that is connected to base stations. The CSGs shown in Figure 2-3 are APs.

IPRAN virtual cluster access uses a dual-control plane solution to ensure control plane reliability. Therefore, masters are classified as primary or secondary masters. In normal circumstances, the control plane is located on the primary master. If the primary master fails, the control plane switches to the secondary master.

Compared with a traditional IPRAN solution, IPRAN virtual cluster access has changes in the aspects, such as the control plane, data plane, management plane, network adjustment, and reliability.
