Abstract

A method is provided in one example embodiment and includes receiving a request associated with a flow over a wireless link, where the request specifies resource requirements for the flow. The method also includes mapping an Internet protocol (IP) flow description to a plurality of tunnel IP addresses, and mapping a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

Claims

1. A method, comprising:

receiving a request associated with a flow over a wireless link, wherein the request specifies resource requirements for the flow;

mapping an Internet protocol (IP) flow description to a plurality of tunnel IP addresses; and

mapping a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

2. The method of claim 1, further comprising:

recovering asynchronous signaling of updated transport IP addresses as a result of at least one mobility event.

3. The method of claim 1, further comprising:

reconfiguring a message received from an application function in order to provide a mapping to the tunnel IP addresses.

4. The method of claim 3, wherein the message includes media component descriptions and uplink/downlink bandwidth data.

5. The method of claim 1, wherein the wireless link is coupled to a Data over Cable Service Interface Specification (DOCSIS) link associated with a cable modem and a cable modem termination system (CMTS).

6. The method of claim 5, wherein Packet Cable Multimedia (PCMM) interfaces are used to establish the QoS for a DOCSIS IP transport network.

7. The method of claim 1, wherein remote authentication dial in user service (RADIUS) protocol interim messages are used for signaling the tunnel IP addresses.

8. The method of claim 1, further comprising:

signaling an access network for previously allocated resources to be released; and

signaling the access network for newly allocated transport resources to be reserved for tunneled transport.

9. The method of claim 1, wherein the request includes a quality of service parameter corresponding to the resource requirements.

10. The method of claim 1, wherein the tunnel IP addresses are associated with a control and provisioning of wireless access points (CAPWAP) tunnel between a Wi-Fi access point (AP) and a wireless local area network controller (WLC).

11. The method of claim 1, wherein the tunnel IP addresses are associated with a GPRS Tunneling Protocol (GTP) tunnel between a service gateway (SGW) and a packet data network (PDN) gateways (PGW).

12. The method of claim 1, wherein the tunnel IP addresses are associated with a GPRS Tunneling Protocol (GTP) tunnel between an eNode B (eNodeB) and a service gateway (SGW).

13. The method of claim 1, wherein a layer-1 point of attachment (PoA) with an access network is changed as a result of at least one mobility event.

14. The method of claim 13, further comprising:

providing an asynchronous indication to a previous querying element that at least one of the tunnel IP addresses have changed as a result of the at least one mobility event.

15. Logic encoded in non-transitory media that includes code for execution and when executed by a processor operable to perform operations comprising:

receiving a request associated with a flow over a wireless link, wherein the request specifies resource requirements for the flow;

mapping an Internet protocol (IP) flow description to a plurality of tunnel IP addresses; and

mapping a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

16. The logic of claim 15, the operations further comprising:

reconfiguring a message received from an application function in order to provide a mapping to the tunnel IP addresses, wherein the message includes media component descriptions and uplink/downlink bandwidth data.

17. The logic of claim 15, wherein the wireless link is coupled to a Data over Cable Service Interface Specification (DOCSIS) link associated with a cable modem and a cable modem termination system (CMTS).

18. An apparatus, comprising:

a memory element configured to store electronic code;

a processor operable to execute instructions associated with the electronic code; and

a mapping function configured to interface with the processor such that the apparatus is configured to;

receive a request associated with a flow over a wireless link, wherein the request specifies resource requirements for the flow;

map an Internet protocol (IP) flow description to a plurality of tunnel IP addresses; and

map a framed IP address to an access point (AP) tunnel endpoint address in order to establish a quality of service (QoS) for tunneled traffic.

19. The apparatus of claim 18, the apparatus being further configured to:

reconfigure a message received from an application function in order to provide a mapping to the tunnel IP addresses, wherein the message includes media component descriptions and uplink/downlink bandwidth data.

20. The apparatus of claim 18, wherein the wireless link is coupled to a Data over Cable Service Interface Specification (DOCSIS) link associated with a cable modem and a cable modem termination system (CMTS).

21. The apparatus of claim 18, wherein the wireless link is associated with a selected one of a group of transport networks, the group consisting of:

a) a control and provisioning of wireless access points (CAPWAP) network;

b) a DOCSIS network; and

c) a Telecoms &

Internet converged Services &

Protocols for Advanced Networks (TISPAN) network.
