The Solution
In order to generate the missing Circuits, the user has to create a Topological SNC in the FO.
Following questions have to be asked before starting the solution process:
• How is the third party equipment is connected to the network?
• What kind of end-to-end connectivity is done inside the FO?
We will study the two possible answers in our network with four nodes.
• The Equipment Cross Connects at P12.
Once created, the FOXMAN-UN NP will scan for the new connectivity, it will detect:
− P12 Trail between the two LOMIF around the FO;
Its Path is {MC LC SNC(topological) LC MC}.
Its Path is {MC LC SNC(topological) LC MC}.
− There are two Circuits at P0_nc that uses P12 Trail;
Both have the Path {SNC LC SNC}.
Both have the Path {SNC LC SNC}.
• The Equipment Cross Connects at P0_nc
In the FO the P0_nc point does not exist. The FOXMAN-UN NP user has to create
− two Trails at P12 routed through the two existing Sections;
− the two missing P0_nc topological Circuits.
For each P0_nc Topological SNC, the connectivity search creates in the same application the two Circuits.
