Abstract: A method and system for packet service category requests to asymmetric digital subscriber line (“ADSL”) latency paths. A data packet request from a customer premise distribution network with a desired service category (e.g., quality-of-service) and a desired latency is mapped to an ADSL device latency interface by checking a latency mapping policy. This mapping provides a virtual connection with a desired service category and a desired latency over ADSL links. The latency mapping includes an embedded service category mapping allowing differential services to be provided for user information based on a desired service category. The latency mapping mechanism may allow easier use of end-to-end packet service categories such as type-of-service categories, for data packets such as Internet Protocol (“IP”) data packets, or Voice over IP (“VoIP”) data packets over real-time asymmetric digital subscriber line links.

Abstract: A method and system for mapping virtual connections to asymmetric digital subscriber line (“ADSL”) latency paths. A request for virtual connection from a transport network (e.g., Asynchronous Transport Mode, Frame Relay, etc.) with a desired service category (e.g., quality-of-service) and a desired latency is mapped to an ADSL device latency interface by checking a latency mapping policy. This mapping provides a virtual connection with a desired service category and a desired latency over ADSL links. The latency mapping includes an embedded service category mapping from a transport network to latency paths at an ADSL transmission convergence sub-layer allowing differential services to be provided for user data based on a desired service category. The latency mapping mechanism may help provide use of end-to-end service categories such as quality-of-service categories, over real-time ADSL links.
