Multi-pointed Media Channels: Multi-source multi-destination
- TR-512.A.4 Figure 4-28
- Representation of topology and frequency slot occupancy
- Agree to use the Bidirectional overlaid trees approach to tackle the issue
- Nigel Davis Start to draw simple single tree, find minimal forms, then draw the overlaid tree, then use in both TAPI and Core
- Pattern of simple tree (non-intersecting)
- Primitives: Merge (M) / Split (S)
- n nodes: 2**n options
- e.g., 2 nodes: 2**2=4 options: MM, MS, SM, SS
- Pattern of overlaid trees
2021.02.04 brief discussion
- Simple tree structure to evaluate network blocking
- Build tree structure for each of the points (Transponders or ROADMs), then use overlay tree to evaluate blocking.
- For each of the originating points (e.g., A, B, C, D, etc.), build a transmit tree through the intermedate coupler/splitter nodes to the end points (i.e., A-126.96.36.199.5-J; A-188.8.131.52.5.-L; etc.), then look at the overlapping segments (e.g., 2.3) of the overlaid trees (e.g., A-184.108.40.206.5-J and C-2.3-G).
- Identify the disjoint trees (e.g, B and C)
- Nigel Davis Malcolm BettsWrite text to explain the restriction and rules for bi/uni-directional for evaluating network blocking. Aim for adding to TR-512.A.4 (section 4.4.9)
