Speed management has been an extensive focus of traffic safety research dating back to the 1960’s. Research has generally shown crash risk to increase as the average speed of traffic increases and as the standard deviation of travel speeds increases within a traffic stream. However, research as to the effects of speed limits has been somewhat inconclusive. This study investigates how speed limi...

Location management is one of the fundamental issues in cellular networks. It includes two operations: location update and paging. The goal of location management is to minimize the combined cost of these two operations. Recently a distance-based scheme using a pre-defined look-up table for location updates has been proposed. The table describes the relationship between the distance and the tim...

We describe our Connection Management Access Protocol (CMAP) for managing multipoint connections in highspeed packet switched networks. A multipoint connection is a communication channel between two or more clients of the network, where all data sent by one client is received by all other clients. A point-to-point connection is a special case of a multipoint connection involving only two client...

A high speed transport system must be able to manage the Quality of Service (QoS) requirements of multimedia applications. QoS management functions in this paper are related to OSI management functional areas and RACE telecommunications management requirements. We discuss especially management functions for QoS translation, admission control and resource management, monitoring and accounting us...

Price advantage & ease of provisioning of Ethemet over ATM is spurring the deployment of traditional Ethemet switches in Access Networks. Fast Ethemet (FE) and Gigabit Ethemet (GE) switches for enterprise LANs lack traffic management (TM) features making them unsuitable for widespread QoS enabled Access Networks deployment. In this paper, we present efficient hardware architectures for Ethemet ...

We propose an efficient solution to optimize buffer dumping allowing to reduce significantly the losses caused by buffer overflow. To highlight the proposed architecture we have analyzed its performance compared with different configurations of polling scheme.
