Grand Unified Testbed — one origin, four paths, one player Diagram

Read it this way

• One MSP Media Origin on the left, one Reference Player on the right, four delivery paths between them.
• Rows are the four testbeds, ordered by how much machinery each adds to the Baseline.
• Only the middle column changes per testbed. The origin and the player are the same software everywhere.

Baseline has no middle column

• Baseline reaches the player with no transmission scheduling at all — that is what makes it the control case.
• The gap is deliberate, not an unfilled cell.
• Baseline is the control case every other row is measured against.

What this licenses

• Functional results transfer across rows, because the shared components are the same software.
• Performance results do not: each row sits on different infrastructure with its own limiting factors.
• What decides which content moves is the Supply & Demand Control diagram, not this one.
