20th International Teletraffic Congress (ITC20) http://www.itc20.ca 17-21 June 2007 (paper submission deadline: October 31, 2006)

For 50 years, the International Teletraffic Congress (ITC) has been the internationally prominent conference for experts involved with the application of teletraffic theory and engineering to state-of-the-art networks. We are pleased to announce the continuation of this tradition in the 20th International Teletraffic Congress (ITC-20), which will be held in Ottawa, Canada, on 17-21 June 2007. Attached is the call for papers.

If your work is within the scope of the conference theme, we would like to encourage you to submit a paper to share your results in an international forum.

We hope that you will include ITC-20 in your 2007 conference plan. Thank you and best regards,

Network convergence is happening. Globally, major network operators have incorporated network convergence into their strategy to grow service revenues and reduce operating costs. Network convergence is multi-faceted. Convergence occurs in applications (integrated messaging, Voice over IP), in network control (portable numbers, SIP, Mobile IP), in the transport layer, as well as in the access network. In the transport layer, the operators' networks are evolving from multiple networks, each specialized for particular services and applications (Wireline, Wireless, Voice, Data, Signaling), towards single IP-based networks that can support existing and future services and applications. This convergence of networks means that various types of traffic flows, which have been carried by separate specialized networks, must now share the resources of a single network. In the access, for example, a broadband carrier may seek to add mobility to its service offerings by untethering the broadband access with WiFi and, later, WiMax technologies. On the other hand, a mobile carrier is more likely to add broadband to its existing mobility services through evolution to 3G architectures.

Network convergence will be successful only if the quality of the individual services is maintained in the new network environment without undue increased costs. The quality of service delivery is critically dependent on how network performance and availability, as experienced by the traffic flows, are managed. Managing traffic performance is a critical enabler for success. Reaching the desired performance levels requires processes such as network planning, resource engineering, and network monitoring. Such processes have been successfully used in various types of service-specific networks. Converged networks, however, bring new challenges - novel architectures and technologies, new modes of sharing network resources, new quality targets for services and applications, new signaling and control protocols. The impact of multi-operator competition, on traffic demand forecasting, end-to-end QoS provisioning and pricing policies needs to be accounted for in a converged network architecture.

To enable the success of convergence in the face of these centrifugal forces, networks need to be designed to be robust to uncertainty in the traffic demand patterns and to be resilient to failures. Such design objectives motivate interest in robust, resilient network architectures, adaptive resource management and control methods, traffic models of new services and applications, novel traffic engineering methods, revised forecasting techniques, and compatible network planning and design tools.

For more that 50 years, the International Teletraffic Congress has brought together network operators, equipment vendors and academic researchers to share their knowledge on the use of quantitative modeling and analysis to plan, design and operate state-of-the-art network solutions. Network convergence is now the state-of-the art solution. In ITC-20, there will be stimulating discussions on traffic performance in converged networks. ITC20 seeks original paper contributions on recent research results, operational experiences and identification of key future issues in managing the traffic performance of converged networks. The papers should focus on the use of quantitative models, analysis and optimization methods to plan, design and manage converged networks. Topics of interests include, but are not limited to, the following:
