Local Area Network (LAN) switches are increasingly being used to subdivide large LAN segments into multiple connected LAN "microsegments." A LAN switch is similar to a LAN bridge, but is typically higher in performance and has more ports. Communicatioim between stations on different segments is through 1 he LAN switch. In this paper, a performance analysis is presented for a Token Ring LAN switch for the clas!& of protocols known as request-response protocols.Request-response protocols are typical of many clientfserver applications including transaction procesrring. A performance model based on a detailed accounting of network delay components is presented. The performance model quantXes the importance of mimimizing latency within a LAN switch. Two LAN switch frame forwarding architectures are described and evaluated. The architectures are store-and-forward and cut-through frame forwarding. The performance model in this paper demonstrates that the benefits of low delay in cut-through switching extend wen to situations where attached Token Ring segments have a very high utilization.

IEEE EAB Awards and Recognition Committee T HE 2018 IEEE Educational Activities Board (EAB), chaired by IEEE Educational Activities Vice President Witold Kinsner, upon the recommendation of the EAB Awards and Recognition Committee (ARC) has named the recipients of the 2018 IEEE EAB Awards. EAB Awards recognize and honor individuals and companies for major contributions to engineering and technical education. Awards are given for meritorious activities in accreditation, continuing education, educational innovation, pre-university education, service to the IEEE EAB, standards education, employee professional development, and informal education systems, as well as related achievements that advance the practice of engineering and engineering education. IEEE-Eta Kappa Nu (IEEE-HKN) is the student Honor Society of IEEE dedicated to encouraging and recognizing excellence in IEEE technical fields of interest. It honors excellence in engineering by recognizing the leaders of today and tomorrow. Members consist of students, alumni, and other professionals who have demonstrated exceptional academic and professional accomplishments. The EAB Awards Reception and Presentation was held on
