Question: In a constrained UE, which reference points should the SEAL client use for interactions with the SEAL server when utilizing the Light-Weight Protocol (LWP)?
Option 1: LWP-1 with the LWP proxy and exclusively LWP-2 for transport and routing
Option 2: LWP-1 with the LWP proxy and either LWP-2 or LWP-HTTP-2 for transport and routing
Option 3: Directly LWP-2 or LWP-HTTP-2 without using the LWP-1 reference point
Option 4: Only LWP-3, regardless of the transport and routing needs
Explanation: In a constrained UE, to efficiently manage resources while ensuring effective communication, the SEAL client is specified to utilize the Light-Weight Protocol (LWP) through the LWP-1 reference point with the LWP proxy. For the actual transport and routing of signaling to the SEAL server, flexibility is offered by allowing either LWP-2 or LWP-HTTP-2, catering to different network conditions or requirements. This approach balances the need for lightweight protocols in constrained environments with the necessity of reliable and adaptable communication pathways.
