Network Adjustment for IP RAN Virtual Cluster Access

Network Adjustment for IP RAN Virtual Cluster Access

Compared with a traditional IPRAN solution, virtual cluster access has more simple and intelligent network adjustment and less maintenance workloads.

In a traditional IPRAN solution, a large number of complex configurations are required to implement service bearing. If you add or delete a node, you must modify configurations on other nodes accordingly, which results in complex maintenance.

After virtual cluster access is deployed, you need to only enable an added node or disable a deleted node without modifying configurations on other nodes.

As shown in Figure 2-18, when a non-virtual cluster access solution is used, explicit paths are configured for all TE tunnels from CSGs to AGGs. CSG4 needs to be added to the existing network.

Figure 2-18 Network before adjustment

The following steps describes network adjustment steps after virtual cluster access is deployed.

Step 1:

Figure 2-19 Network adjustment step 1
  • Before virtual cluster access is deployed, an NMS uses the PnP function to deliver basic configurations to CSG4.
  • After virtual cluster access is deployed, an NMS uses the PnP function to deliver basic configurations to CSG4.

Step 2:

Figure 2-20 Network adjustment step 2
  • Before virtual cluster access is deployed, an NMS delivers MPLS TE configurations to establish a tunnel between CSG4 and AGG1.
  • After virtual cluster access is deployed, a tunnel is automatically established.

Step 3:

Figure 2-21 Network adjustment step 3
  • Before virtual cluster access is deployed, configurations on CSG1 are updated to establish a tunnel between CSG1 and AGG1.
  • After virtual cluster access is deployed, a tunnel is automatically established.
