Differentiated I/O services for applications with their own requirements are very important for user satisfaction. Nonvolatile memory express (NVMe) solid-state drive (SSD) architecture can improve the I/O bandwidth with its numerous submission queues, but the quality of service (QoS) of each I/O request is never guaranteed. In particular, if many I/O requests are pending in the submission queues due to a bursty I/O workload, urgent I/O requests can be delayed, and consequently, the QoS requirements of applications that need fast service cannot be met. This paper presents a scheme that handles urgent I/O requests without delay even if there are many pending I/O requests. Since the pending I/O requests in the submission queues cannot be controlled by the host, the host memory buffer (HMB), which is part of the DRAM of the host that can be accessed from the controller, is used to process urgent I/O requests. Instead of sending urgent I/O requests into the SSDs through legacy I/O paths, the latency is removed by directly inserting them into the HMB. Emulator experiments demonstrated that the proposed scheme could reduce the average and tail latencies by up to 99% and 86%, respectively.

Network applications demand quality of service for enhanced call quality and increased user satisfaction. Hence, implementing queuing discipline at switches and routers in a network will govern the way packets are buffered while waiting for transmission. Queuing disciplines like first-in first-out (FIFO) queuing, priority queuing (PQ), weighted-fair queuing (WFQ), custom queuing and modified weighted round robin are more prominently deployed in network applications. These queuing disciplines help to control and manage network resources by fixing priorities for specific types of data on the network. The paper aims to analyze the quality of service parameters for various real time applications like File transfer protocol(FTP), email, database, Voice over IP(VOIP), video and web browsing,etc., and helps to optimise the use of available network resources. Moreover the quality of the network is compared using different QoS parameters such as end-to-end delay, throughput, jitter and Mean Opinion Score (MOS). This paper focuses on various queuing disciplines with low and high network traffic.

PurposeThe purpose of this study is to measure the gap and compare the quality of services provided by the Central Library of the University of Tehran and Allameh Tabataba'i University and identify the components of service that need improvement in these libraries.Design/methodology/approachIn this study, a descriptive survey method is used for data collection. The study sample contains 205 people selected out of 31,000 members of Tehran University and 100 people out of 15,000 members at Allameh Tabataba'i University. The LibQual tool is used to measure different levels of users' perceptions of library service quality.FindingsBased on the findings of the study, the level of service received at the University of Tehran was higher than the minimum expected level, and at Allameh Tabataba'i University, the level of service received was lower than the minimum level of expected, which indicates users' satisfaction at this index at the University of Tehran and users' dissatisfaction at Allameh Tabataba'i University. In the index of information control and library as a place in Tehran University, the level of service received was higher than the minimum level and in Allameh Tabataba'i University, the level of service received was lower than the minimum level, which indicates the satisfaction of users in this index at the University of Tehran and users' dissatisfaction at Allameh Tabataba'i University.Practical implicationsService quality, or quality of service, is the measurement and comparison of the size of service provided with users' expectations. The following principles illustrate the dimensions of service quality: Quality of service is much more difficult to measure than the quality of goods. The quality of service is based on users' expectations. Quality of service varies in status, meaning that the quality of a service is measured against the customer's initial expectations of that service (Parasuraman et al., 1985).Originality/valueBeing the first performance evaluation, community synchronization, economic justification, user satisfaction and customer orientation are the values of the present study.
