| Abstract | ATM networks have shown to reveal difficulties in simultaneously guaranteeing the requested quality-of-service while efficiently utilizing all the available bandwidth for economic reasons. The ABR (available bit rate) service class was designed to fill the gap of bandwidth with less delay but loss sensitive traffic. Due to the bursty nature of higher-priority traffic and the resulting bandwidth fluctuations a flow control is required for ABR that avoids buffer overflow and cell loss. These demands can both only be supported by credit-based flow control. It offers immediate access to the full link bandwidth without a ramp-up time. However, though its behaviour is deterministic an analysis by queueing models is impossible. In this paper we treat stability, performance and dimensioning issues of a representative class of credit-based flow control protocols with a new stochastic Petri-net model. We use its formalism to prove its stability and study the utilization performance in all operation regions with it. This implies the proposed dimensioning of buffer sizes and parameters, which is an important task during connection admission. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
