This paper first introduces bandwidth utilization metric and then analyzes sorted-priority schedulers in the terms of the metric. The results show that the utilization is directly proportional to both the number of delay bound classes and the dependency of delay bound on rate but inversely proportional to packet size.

Cache memories have been incorporated into almost all modern, general-purpose microprocessors. To maintain data consistency between cache structures and the rest of the memory systems, most of these caches employ either a writeback or a write-through strategy to deal with store operations. Writethrough caches propagate data to more distant memory levels at the time each store occurs, producing ...

Multiplexing is a method by which multiple analog message signals or digital data streams, coming from different sources are combined into one signal over a shared medium. In this paper, we present an overview of different multiplexing techniques in bandwidth utilization. We focus on the three well-known multiplexing technique used in bandwidth utilization which are Frequency-Division Multiplex...

Current IaaS clouds provide performance guarantee on CPU and memory but no quantitative network performance for VM instances. Our measurements from three production IaaS clouds show that for the VMs with same CPU and memory, or similar pricing, the difference in bandwidth performance can be as much as 16×, which reveals a severe price-performance anomaly due to a lack of pricing for bandwidth g...

In confirmation of earlier developed theory, this paper presents some very promising empirical results obtained for tradeoff between message bandwidth utilization versus error incurred in a predictive filtering method called predictive quantization. The results relate bandwidth utilization and error against quantum size for the same federation executing on DEVS/HLA (an HLA compliant distributed...

To guarantee quality of service (QoS), the requirements of video transmission, such as delay and cell loss rate (CLR), are very stringent. These constraints are diicult to meet if high network utilization is desired. In this paper, dynamic band-width allocation algorithms, in which scene change identiication is incorporated, are proposed to improve the bandwidth utilization. The bandwidth alloc...

Carrying IP traffic over connection-oriented networks requires the use of bandwidth on demand schemes at gateways or network interfaces. A new virtual queue occupancy, which is more accurate than the classical one, is being proposed for IP/SONET bandwidth on demand. Based on the virtual queue occupancy, two enhanced periodic approaches for lossless services, LAVQ and LAVQL, are simulated and ev...
