Abstract

Quality of Service (QoS) and/or bandwidth allocation is managed in a Regional/Access Network (RAN) that provides end-to-end transport between a Network Service Provider (NSP) and/or an Application Service Provider (ASP), and a Customer Premises Network (CPN) that includes a Routing Gateway (RG). A first subsystem is configured to manage QoS and/or bandwidth allocation for an access session in the CPN. A second subsystem is configured to manage QoS and/or bandwidth allocation for an application flow in the CPN. Thus, the RAN can independently manage QoS, session authentication and/or bandwidth allocation for an access session and for an application flow.

a regional/access network to application service provider service session message generator that is configured to send an establish service session response message from the regional/access network to the application service provider to indicate to the application service provider what regional/access network resources are authorized for an access session;

a regional/access network to network service provider service session message generator that is configured to send an establish service session response message from the regional/access network to the network service provider to indicate to the network service provider what regional/access network resources are authorized for a service session;

a network service provider to regional/access network service session message generator that is configured to send an establish service session request message from the network service provider to the regional/access network to request establishing a service session and to indicate to the regional/access network a life span of the requested service session;

wherein the first subsystem comprises a regional/access network to routing gateway access session message generator that is configured to send an update session bandwidth info message from the regional/access network to the routing gateway to notify the routing gateway when new bandwidth and new quality of service information is available for a session;

wherein the regional/access network to routing gateway access session message generator is further configured to send an update session bandwidth response message from the regional/access network to the routing gateway to notify the routing gateway of access session bandwidth and quality of service settings that are stored in the regional/access network for the customer premises network;

wherein the first subsystem further comprises a routing gateway to regional/access network access session message generator that is configured to send an update session bandwidth request message from the routing gateway to the regional/access network to obtain from the routing gateway access session bandwidth and quality of service settings that are stored in the regional/access network for the customer premises network;

wherein the second subsystem further comprises a regional/access network to application service provider application flow message generator that is configured to send a create application flow control response message from the regional/access network to the application service provider to indicate to the application service provider that an application flow control request from the application service provider to the regional/access network has been accomplished successfully;

wherein the second subsystem further comprises an application service provider to regional/access network application flow message generator that is configured to send a create application flow control request message from the application service provider to the regional/access network to request establishing an application flow and to indicate to the regional/access network a type of application flow, a priority of the application flow and a bandwidth of the application flow; and

wherein the regional/access network to application service provider application flow message generator is further configured to send a query application flow control response message from the regional/access network to the application service provider to indicate to the application service provider what resources are assigned to an application flow.

2. A system according to claim 1 wherein the second subsystem comprises a regional/access network to routing gateway application flow message generator that is configured to send an update application flow control information message from the regional/access network to the routing gateway to notify the routing gateway when new bandwidth and new quality of service information is available for an application flow.

A system according to claim 2 wherein the regional/access network to routing gateway application flow message generator is further configured to send an update flow control response message from the regional/access network to the routing gateway to notify the routing gateway of application flow bandwidth and quality of service settings that are stored in the regional/access network for the customer premises network.

4. A system according to claim 3 wherein the second subsystem further comprises a routing gateway to regional/access network application flow message generator that is configured to send an update application flow control request message from the routing gateway to the regional/access network to obtain from the routing gateway application flow bandwidth and quality of service settings that are stored in the regional/access network for the customer premises network.
