Hardware support for high-priority traffic in VLSI communication switches

by Yuval Tamir, Gregory L. Frazier - IEEE J. Par. Distrib. Comp , 1992
"... Both multistage interconnection networks used in multiprocessors and direct networks used in multicomputers are composed of small n ×n switches. The design of these switches is of critical importance for achieving high-bandwidth low-latency interprocessor communication. Interprocessor traffic genera ..."

generated by devices that must meet real-time requirements as well as certain other system activities, such as exception handling, may require particularly low communication latency. Special support for such high-priority traffic may thus be necessary in many multiprocessor and multicomputer systems. We

High Priority Traffic Separation in Shared Ethernet Networks1

by Ricardo Moraes, Francisco Vasques
"... In this paper, it is proposed an enhanced algorithm for the collision resolution in shared Ethernet networks. Such algorithm, referred as high priority Binary Exponential Backoff (h-BEB), provides high priority traffic separation, enabling the support of real-time communications. To our best knowled ..."

Absolute QoS in Synchronous Optical Packet Switched Networks

by Astrid Undheim, Harald Øverby, Norvald Stol
"... This paper presents an adaptive service differentiation scheme for a bufferless synchronous Optical Packet Switched (OPS) network. Wavelength allocation is used for service differentiation, where the number of wavelengths reserved for high priority traffic (L) is adjusted according to changes in the ..."

"... The IEEE 802.11e EDCF mechanism cannot guarantee the QoS of high-priority traffic as the bandwidth consumption of the low-priority traffic increases. Also, the existence of high priority traffic undermines link utilization of low prior-ity traffic. To solve these problems, we propose the S-EDCF sche ..."

Routing of High-Priority Packets in Wireless Sensor Networks

by Erol Gelenbe A, Edith Ngai B, Poonam Yadav C
"... The Random Re-Routing (RRR) algorithm has recently been introduced to provide fast adaptive priority routing to rapidly convey packets of important events in sensor networks, while forwarding routine and lower priority traffic along some secondary network paths. This technique can be applied for sen ..."

Feedback Control of Multiloop ABR Traffic in Presence of CBR/VBR Traffic Transmission

by Yongdong Zhao, San-qi Li - In Proc. of the ICC’96 , 1996
"... Existing works on ABR feedback control design basically neglected the effect of multiple feedback loop delays and high-priority CBR/VBR traffic transmission. With multiloop delays, the already existing low-frequency high-magnitude oscillations of ABR traffic within each loop can become much worsened ..."

The iSLIP Scheduling Algorithm for Input-Queued Switches

by Nick McKeown , 1999
"... An increasing number of high performance internetworking protocol routers, LAN and asynchronous transfer mode (ATM) switches use a switched backplane based on a crossbar switch. Most often, these systems use input queues to hold packets waiting to traverse the switching fabric. It is well known th ..."

ANew Dynamic Bandwidth Allocation Protocol with Quality of Service in Ethernetbased Fu-Tai An, Yu-Li Hsueh, Kyeong Soo Kim, Ian M. White, and Leonid G. Kazovsky

by Optical Communication Research, Fu-tai An, Yu-li Hsueh, Kyeong Soo Kim, Ian M. White, Leonid G. Kazovsky - International Conference on Wireless and Optical Communication (WOC 2003 , 2003
"... Ethernet-based Passive optical network (E-PON) is the key for next generation access networks. It must have the property of high efficiency, low cost, and support quality of service (QoS). We present a novel media access control (MAC) protocol that maximizes network efficiency by using dynamic bandw ..."
Abstract - Add to MetaCart
bandwidth allocation (DBA) algorithm suitable for E-PON. This protocol minimizes packet delay and delay variation for high priority traffic to ensure QoS. Simulation results show excellent network throughput. Simulation results also show low packet delay and packet delay variation for high priority traffic
