In optical switching networks, optical information (packets/bursts) that are forwarded from an optical switch to another through the network could entering a queue of a certain length in each node and may be waiting inside this node before it will be transmitted to the next node. Various queueing models have been widely applied as the main tool in optical switching networks for modeling and performance evaluation analysis of the switching nodes. In this paper, studying the performance analysis of an optical switching node is discussed at Finite and Infinite queueing models to have the optimum queueing model for optical core node switch design. The waiting delay time, the average expected number of optical packets and the loss probability of packets in the optical switch are estimated at variable traffic loads and different wavelength channels.

The purpose of this study is to analyse the implementation of three national education standards (SNPs), namely management standards, graduates competency standards, and teacher and education staff at the Ummul Quro (UQ) Islamic school and the Bogor Hajj Persaudaraan Foundation (YPHB) using importance-performance analysis (IPA) model. This study uses primary data sourced from a questionnaire distributed to thirty respondents. The test results reveal that the application of management standards, graduate competency standards, and standards for teachers and education personnel at Islamic boarding schools UQ and YPHB have been optimal with a level of compatibility between importance and performance at a very good level. The implementation of 3 SNPs in UQ and YPHB based on IPA showed that Islamic education institutions must strive to improve performance through compilation of the respective duties, job description, use of work procedures, and socialization management system and maintain several attributes that have been assessed as good, such as formulate vision and mission, goals, targets and strategic plans, organizational structure, guidelines. The institution also has to maintain the stability of the level of satisfaction with the quality of the performance, implementation of activities according to the agreed program, involvement of community participation and partnerships/school committees, monitoring the implementation of the program.   Received: 28 April 2021 / Accepted: 26 July 2021 / Published: 5 September 2021
