Resource control and signaling requirements and protocols in ITU-T Q5/SG11

Submission Date:July 1, 2008

highlight of current activities 1
Highlight of Current Activities (1)
  • Developing standards to define the resource control and signaling requirements and protocols in NGN

• Recently completed work:

    • Architectural framework for the Q.33xx series of Recommendations
    • Protocol at the interface between Service Control Physical Entity (SC-PE) and Resource and Admission Control Physical Entity (RAC-PE) (Rs interface) version 1
    • Protocol at the interface between Transport Resource Control Physical Entities (TRC-PEs) (Rp interface) version 1
    • Protocols at the Rw interface between a Policy Decision Physical Entity (PD-PE) and a Policy Enforcement Physical Entity (PE-PE): Overview
    • Protocol at the interface between Policy Decision Physical Entity (PD-PE) and Policy Enforcement Physical Entity (PE-PE) (Rw interface) version 1: COPS Alternative, H.248 Alternative and Diameter
highlight of current activities 2
Highlight of Current Activities (2)
    • Protocol at the interface between a Transport Resource Control Physical Entity (TRC-PE) and a Transport Physical Entity (T-PE) (Rc interface): COPS alternative and SNMP Profile
    • Protocol at the interface between Policy Decision Physical Entity (PD-PE) and Transport Resource Control Physical Entity (TRC-PE) (Rt interface) in access network
    • Signalling flows for resource control
  • Currently building specifications for QoS Coordination Protocol
  • Q.PCNApp newly created to describe enhancement of RACF to use pre-congestion notification (PCN)
  • Recently create resource control protocol for Flow State Aware Access QoS Control in NGN
  • Working closely with global liaison partners.
  • Published 11 standards in ITU-T 4 years period (see slide 12,13) -- 15 currently in draft format.
strategic direction 1
Strategic Direction (1)
  • The ITU-T Q5/SG11 standards have been defined to fulfill the following tasks (but not limited to):
    • controlling gates at networks boundaries in NGNs;
    • supporting interactions of applications and session control functions with resource control functions in NGNs;
    • controlling media gateways in NGNs;
    • controlling specialized resources in NGNs;
    • interaction among resource control domains; and
    • Joint development of specifications of interfaces to adjacent layers with relevant Questions groups.
  • Whenever possible, ITU-T Q5/SG11 standards are align with the work of other SDOs, including the ETSI, 3GPP, IETF and DSL Forum
    • Continue with ETSI and 3GPP coordination and collaboration
    • Established important relationships with all of the leading organizations working in the resource control and signaling requirements/protocols realm to share our end-to-end view of the standards being developed.
strategic direction 2
Strategic Direction (2)
  • Q5/SG11 is developing standards for signaling and control interactionsbetween service and transport layers to enable, e.g., session servers and application servers to control transport resources and associated QoS, in real time
    • Northbound Interface Signaling Requirements (Rs)
    • Horizontal Interface Signaling Requirements (Rt, Rp, Ri, Rd,Rh)
    • Southbound Interface Signaling Requirements (Rw, Rc)
  • Q5/SG11 is developing QoS Coordination Protocol, enhancement of RACF to use pre-congestion notification (PCN) and resource control protocol for Flow State Aware Access QoS Control in NGN
  • Timely completion of deliverables to support deployment of standardized resource admission and control architecture
challenges
Challenges
  • Resource control and traffic management in support of IPTV service
  • Signaling requirements and protocols supporting mobility control
  • Signaling requirements and protocols between DSLAM and BRAS
next steps actions
Next Steps/Actions
  • Architectural framework for the Q.33xx series ofRecommendations version 2
  • Rs, Rp, Rw, Rc, Rt version 2 and continue Ri, Rd, Rh
  • Continue QoS Coordination Protocol, enhancement of RACF to use pre-congestion notification (PCN) and resource control protocol for Flow State Aware Access QoS Control in NGN
  • Coordination between RACF and GMPLS/PCE-controlled transport network
  • Continue to work cooperatively with external organizations on aligning efforts and work products.
