| Abstract | Performance testing of ATM equipment is here dealt with. In particular, the attention is paid to frame-level metrics, recently proposed by the ATM forum because of their suitability to reflect user-perceived performance better than traditional cell-level metrics. Following the suggestions of the ATM forum, more and more network engineers and production managers are nowadays interested in these metrics, thus increasing the need of instruments and measurement solutions appropriate to their estimation. Trying to satisfy this exigency, a new VXI-based measurement apparatus is proposed in the paper. The apparatus features a suitable software, developed by the authors, which allows the evaluation of the aforementioned metrics by making simply use of common ATM analyzers; only two VXI line interfaces, capable of managing both the physical and ATM layer, are, in fact, adopted. At first, some details about the hierarchical structure of the ATM technology as used as the main differences between frames, peculiar to the ATM adaptation layer, and cells characterizing the lower ATM layer are given. Then, both the hardware and software solutions of the measurement apparatus are described in detail with a particular attention to the measurement procedures implemented. At the end the performance of a new ATM device, developed by Ericsson, is assessed in terms of frame-level metrics by means of the proposed apparatus. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
