Network requirements between NSP and other components

NSP and OSS clients

The bandwidth requirements between NSP and OSS clients depend on the number of concurrent connections and on the type of transactions that are performed. For a single provisioning thread, Nokia recommends providing 50 kbps of bandwidth from the OSS client to the NSP cluster. An OSS client that performs frequent query operations (for example, port or service inventory) must be provided additional bandwidth.

NSP and GUI clients

The bandwidth requirements between NSP and GUI clients mostly depends on the size of the network. A larger network with more nodes and services requires more data to download to GUI clients. Optimal GUI performance is achieved with 10 Mbps of bandwidth with minimal network latency. Nokia recommends providing a minimum of 2.5 Mbps of bandwidth.

High network latency between the NSP and GUI clients slows GUI performance. Nokia recommends limiting the round-trip network latency time to 100 ms.

NSP and NFMP

The bandwidth requirements between NSP and NFM-P depends on the following factors:

• the number of NEs, LSPs, and services configured on the NFM-P

• the frequency of NE updates to the NSP

When an NSP system resynchronizes with NFM-P, optimal performance is achieved with 50 Mbps of bandwidth between NSP and NFM-P. Nokia recommends providing a minimum of 25 Mbps of bandwidth.

Network latency impacts the time it takes for the NSP to resynchronize a large amount of data from the NFM-P. Nokia recommends limiting the round-trip network latency time to 100 ms.
