Call for papers: Performance Assessment of New Internet Services

Call for papers: Performance Assessment of New Internet Services

A special issue of International Journal of Communication Networks and Distributed Systems

The internet has shown to be the major enabler for all kinds of services via a common infrastructure. Since the early applications, such as remote login, e-mail, file transfer and web browsing, many new applications and services have entered the stage, where overlay networks play an important role. When broadband access technologies reached private users, file sharing became popular. Telecommunication providers have discovered internet technology as a cost-saving alternative to classical telecom technology. 3GPP has standardised the internet multimedia system (IMS), which is nowadays even used in the world of fixed access networks to handle the co-existence of voice, TV and internet (so-called Triple Play) on access links.

New application domains, such as e-health, e-government, e-tourism etc., have appeared. Many new services use other services, forming composite services or service supply chains based on the internet. Thus, the "anything-over-IP-over-anything" principle has become a reality.

This emergence of new applications raises challenges. The internet has never been designed for fulfilling all imaginable application needs. Over the years, the basic best-effort paradigm has been enhanced by network-level quality of service (QoS) measures. Even so, internet packet delivery cannot be guaranteed. Applications try to adapt themselves to these volatile conditions, e.g. by modifying the intensity of the data flows or adding some kind of redundancy to be used for error correction which fits the Internet principle of end-to-end control. However, in order to reach the right interplay between applications and services and the internet infrastructure, a good understanding of the characteristics of both is mandatory.

Against this background, this Special Issue focuses on performance assessment of emerging applications and services using the internet.

Suitable topics include, but are not limited to:
  • Overlay-based services
  • Services in triple play scenarios
  • Composite services and service supply chains
  • Mission-critical services
Within these topics may be reported, among others:
  • Measurement methods and results
  • Characterisation of application traffic, including identification of suitable parameters
  • Relationships between user perception and network-level parameters
  • Traffic modelling, including matching methods
  • Assessment of quality of service (QoS) and quality of experience (QoE)
  • Queuing models, taking particularities of service and networks into account
  • Simulation studies
Important Dates
Full papers due: 15 November, 2007
Notification of acceptance: 10 January, 2008
Camera-ready papers due: 10 February, 2008
