CALL FOR PAPERS

IEEE Communications Magazine Feature Topic on

QoS Control in Next Generation Networks

http://www.comsoc.org/pubs/commag/cfpcommag0907a.htm
-------------------------------------------------------------------

In next generation networks, the service plane and the transport plane
will be decoupled and independent. This is clearly evident from
various emerging standards such as 3GPP IP Multimedia Subsystem, 3GPP2
Multi-Media Domain, ITU-T Next Generation Network, ETSI TISPAN, Packet
Cable Multimedia Architecture and Multi Service Forum. All of these
architectures have the following in common: (1) the service plane that
transfers service information (e.g., SIP, HTTP) and manages service
resources to enable advanced user services (e.g., IPTV, push-to-talk),
and (2) the transport plane that delivers end-to-end user packets and
manages transport resources. This architectural approach enables the
service plane and the transport plane to be developed independently,
and provides support for different access technologies based on fixed
(twisted copper cable, coaxial cable, fiber) and wireless media. A
critical component in these architectures is a logical entity that has
a northbound interface to the service plane and southbound interface
to the transport plane to provide the linkage between the two planes.
This entity has been called by different functional names including
policy server, policy decision function (PDF), policy and charging
rules function (PCRF), resource and admission control function (RACF)
and bandwidth manager. Although the entity also performs functions
such as charging control and security control, this Feature Topic will
only focus on QoS-related functions such as admission control, QoS
mapping from service plane (e.g., SDP) to transport plane (e.g., DSCP
marking, policing parameters, etc.), resource monitoring and resource
reservation, and gate control. While the standards development
organizations have been working on the protocol specifications, much
work is needed in the design and performance aspects of this entity in
order to provide end-to-end QoS services in a scalable manner. For
example, it is of interest to have concrete designs to handle
scenarios where end-to-end user packets traverse multiple domains,
each of which is managed by its own PDF. Papers that are tutorial in
nature are strongly recommended. Suggested areas include (but are not
limited to) the following subject categories:

* Overview and comparison of PDF functions in relevant standards
such as ITU-NGN, ETSI TISPAN, 3GPP/3GPP2 and Packet Cable

* Test beds, lab/field trials, and lessons learned from early
deployment

* Issues in overall QoS architectures with decoupled service and
transport planes

* QoS support at the service control function (IMS and non-IMS)
or at the policy enforcement function

* Multidomain admission control and end-to-end performance

* Transport plane performance monitoring such as TRC-FE in
ITU-NGN

* Policy rules and policy decisions

* Authorization, reservation and commitment of network resources
in pull and push models

* QoS mapping from service plane to transport plane

* Algorithms for optimizing transport resources, service
provisioning performance or other performance enhancement
