Network requirements for NSP redundancy and communications within an NSP cluster

Communication requirements between redundant NSP deployments

The network requirements between active/standby NSP clusters depend on the network size (number of NEs and configured services) and the rate of service provisioning activities. The peak bandwidth requirement between redundant servers is 50 Mbps, with a sustained bandwidth of 25 Mbps. Round-trip network latency between the pair of redundant servers must be limited to 100 ms.

Communication between nodes in an NSP cluster

In a multi-node deployment of an NSP cluster, it is recommended that the nodes within the cluster have 1Gbps of Ethernet connectivity with less than 1 ms round-trip latency.
