Abstract

Traffic patterns of data services are known to be highly dynamic and have been characterized as self-similar caused by long-range dependent transfer times and file size distributions. This burstiness appears on various time scales and makes link and network dimensioning more difficult compared to classical voice traffic. In this paper, we adopt dynamic bandwidth adaptation to transport networks, using new features of next generation SDH/SONET known as virtual concatenation (VCAT) and link capacity adjustment scheme (LCAS), which can flexibly provision subwavelength granularities. We quantify the principal interrelation of dynamic bandwidth adaptation and changing traffic characteristics as well as the impact of operational and technical constraints on achievable service quality in depth.
