Academic literature on the topic 'Asynchronous Transfer Mode (ATM) networks'

The Advanced Network Technologies is a research that investigates the technology(s) behind today’s modern networks and network infrastructures – one of these technologies being Asynchronous Transfer Mode (ATM); a technology commonly in place in networks all around the world today. Therefore, this paper focuses its attention on ATM. Dubbed “Modelling and Performance Studies of ATM Networks,” this research looks into the “impact of application segment length on the performance of an ATM network” and the “impact of traffic type data on the performance of an ATM network.” For this research, the authors have used the OPNET Modeler 14.0 Simulation software to create a network model that represents a real-life ATM network. By simulating an ATM network at AUT University New Zealand, the authors can change certain variables, and observe the effects the changes have on performance. As such, one of the impacts that will be explored is the effect that application segment length has on an ATM network. The second impact to be inspected is the impact of different traffic types on an ATM network. For example, Email traffic should theoretically affect an ATM network differently to the way that Voice traffic does. This way of thinking is what will be looked into further.

In asynchronous transfer mode (ATM), networks, buffering is required to reduce cell loss and increase bandwidth utilization by the bursty traffic. Several types of traffic with different performance requirements on delay and loss will share buffer resources. We focus on the fully shared buffer with push-out and a randomized service priority rule. Some conservation relations are obtained which can be used to tune the parameters of the buffering and service disciplines.

This paper presents new multimedia Asynchronous Transfer Mode (ATM) networks which are capable of transmitting voice data efficiently and serving smooth evolution from the existing narrowband voice networks. Fully ATMized networks are characterized by having both rerouting function and switching function. The rerouting nodes multiplex plural calls going through the same route into one ATM cell, namely shared virtual channel identifier (VCI) cell. The shared VCI cell includes fellow cells which contain call data and its VCI. The rerouting node is integrated into a single chip by using CMOS technology. The multimedia ATM networks can be readily implemented by attaching the rerouting nodes to the standard ATM switches.
