Architecture design for regulating and scheduling user's traffic in ATM networks

Abstract: The asynchronous transfer mode (ATM) technique provides a standardized and flexible scheme to transport and switch traffic effectively for different services. To provide satisfactory quality of service (QOS) to all users on the network, it is necessary to control the user's traffic so that network resources can be efficiently and fairly utilized by all the users while still meeting the individual QOS requirement. In this paper, we propose to control the user's traffic at two places in the network: at the user-network interface (UNI) by a traffic shaper or a traffic enforcer, and at the network-node interface (NNI) by a traffic regulator and a traffic scheduler. The traffic shaper/enforcer adopted in our work contains a buffer to delay and shape the violating cells that do not comply with some agreed-upon traffic parameters. The traffic regulator regulates cells at each network node to avoid long bursts being formed which may increase the network congestion probability. A traffic scheduler that follows the traffic regulator schedules the cells' departure sequences based on their delay priorites. We have proposed a general, feasible architecture to implement the traffic shaper, regulator, and scheduler, at various places in the network. A key component, the Sequencer chip, which contains 150k CMOS transistors, has been implemented to realize the architecture.

Quality of service matching for integrated fast packet networks

Abstract: Two aspects of quality of service (QoS) matching for integrated fast packet networks, QoS translation and QoS negotiation, are presented. The user-specified, traffic-dependent QoS has to be translated into corresponding constraints on network-oriented QoS, which are not traffic dependent, so that internal network functions such as routing can be uniformly applied. To accommodate diverse QoS requirements, the network must incorporate QoS negotiation procedures among the network and the users. >

Quality of service in B-ISDN and relation with network management

Abstract: A quality of service (QOS) framework for broadband integrated services digital networks (ISDN) is presented The framework contains network performance (NP), parameters, QOS parameters and a QOS architecture The NP parameters characterizing an asynchronous transfer mode (ATM) network are reviewed The QOS parameters are obtained from the user's service requirements and a QOS time-line model The QOS architecture in the open systems interconnection (OSI) reference model are defined with respect to the network management (NM) framework The QOS framework covers the NM framework and acts an an application of the NM, which is based on the intercommunication between the service user, service provider, and network provider >
