Question: In the Backhaul Adaptation Protocol (BAP), what is the composition of the 20-bit BAP Routing ID field, specifically in terms of its two constituent parts?
Option 1: Leftmost 12 bits for BAP address and rightmost 8 bits for BAP path identity
Option 2: Leftmost 10 bits for BAP address and rightmost 10 bits for BAP path identity
Option 3: Leftmost 8 bits for BAP path identity and rightmost 12 bits for BAP address
Option 4: Entire 20 bits dedicated to BAP address, with no separate field for BAP path identity
Explanation: The correct composition of the BAP Routing ID field is specified as having the BAP address in the leftmost 10 bits and the BAP path identity in the rightmost 10 bits. This balanced division allows for efficient identification and routing within the backhaul network, ensuring both the source (BAP address) and the specific path (BAP path identity) are clearly defined for flow control feedback.
