| Abstract | Delay bounds of data transmissions and system buffer bounds are important parameters of quality of service (QoS) in networked control systems (NCS). They are particularly important for the analysis and design. Generally, the characteristic of round-trip time (RTT) of the switched Ethernet used in NCS can leads to increased burst and buffer loss [15]. And the bandwidth allocated to a switch is highly affected by the load from other switches within the same network. As a result, the service provided by the switch is stochastic [12]. So we use stochastic network calculus to analyze these parameters of QoS in the paper. Both virtual-backlog-centric (v.b.c.) stochastic arrival curve and stochastic service curve are introduced to analyze stochastic service guarantees of NCS. Finally, we get the end-to-end delay bound and buffer bound under different violation probability in two network scenarios, by using popular network topologies as well as two scheduling algorithms. |

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.
