Abstract:
Services sensitive to network quality converge onto general-purpose data networks which, in contrast to special-purpose (e.g., public telephony) networks, lack built-in quality control functions needed by many applications, like Internet telephony or video conferencing. High-volume, high-performance applications such as those in Grid and Cloud computing may be too important for customers to rely on mere promises of network quality, while at the same time requiring connections traversing multiple network operators' domains. Thus, in addition to end-to-end QoS assurances, customers of these applications demand management functionality for those connections made available to them. Traditional routing procedures are insufficient to select paths according to these requirements, as they rely on evaluation of only one parameter (e.g., hop count), while QoS parameters alone will account for multiple independent metrics. We present a solution that addresses these issues by combining a routing procedure, a common set of QoS operations, and an information model for the representation of connection properties within and across administrative domains.
