Planning the Optical-Path-Shared MSP

Capabilities of Supporting the Optical-Path-Shared MSP

When planning the optical-path-shared MSP for Huawei OptiX OSN 2500, first consider the
capabilities of supporting the optical-path-shared MSP.
In the case of the optical-path-shared MSP, one optical interface can be configured into two
MSP groups. Thus, multiple MSP rings can share the same fiber and optical interface.
The OptiX OSN 2500 supports the configuration of the optical-path-shared MSP.
l The SF16 and SL16 boards can process two sets of K bytes, which are located in the first
and fifth STM-1s. The SF16 and Huawei SL16 boards support configuring a single optical interface
into a maximum of two MSP rings.

Planning Principles

To rationally and effectively plan the optical-path-shared MSP protection, the planning
principles should be followed.

In normal situations, in the case of the optical-path-shared MSP, two low-rate line units share
the same high-rate line unit.

In the optical-path-shared MSP, two line STM-16 units at the same rate can share the same line unit.

When the optical-path-shared MSP is configured, on the protection ring, the optical interfaces

in two directions need not be configured into paired slots.
