Question: What is the primary purpose of an LWP (Lightweight Protocol) proxy in the context of Service Enabler Architecture Layer for Verticals (SEAL), in relation to transactions between LWP clients and servers?
Option 1: To establish multiple secure sessions between each LWP client and every LWP server, enhancing security through protocol diversity.
Option 2: To act as a single point of contact for LWP clients, terminating secure transport protocols and enabling access to multiple LWP servers without requiring individual secure sessions.
Option 3: To convert all incoming requests into HTTP format, regardless of the original protocol used by the LWP client.
Option 4: To bypass security measures for LWP transactions within a trusted domain, improving transaction speed.
Explanation: The correct answer, Option 2, highlights the LWP proxy's role in simplifying secure communication between LWP clients and multiple LWP servers. By terminating a secure transport protocol session (e.g., DTLS, TLS) on the LWP-1 reference point with the LWP client, it allows for a single secure session to be established for transactions with several LWP servers reachable by the proxy. This approach enhances efficiency and security management within the SEAL architecture.
