In this paper, we investigate active queue management mechanisms that are designed to enable ATM switches to operate in the low delay/high throughput regime. In particular, we present an analytical framework for random early detection (RED)-like congestion control mechanisms in an ATM multiplexer, and obtain closed form expressions for performance metrics such as throughput and average queueing delays. Based on this analysis, we propose an adaptive mechanism to select the parameters of the congestion control algorithm to optimize the system performance.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

Specifically, the problem concerns a single-server, discrete-time queue with state-dependent probabilistic server availability/interruptions, and is motivated by the analysis of ground station queueing dynamics in a broadband satellite environment, as well as the analysis of a blocking shared-medium ATM switch with input queueing. The system is analyzed for two forms of probabilistic behavior: exponential and hyperbolic forms. The analysis yields several performance metrics of interest, including average system occupancy, average delay, and steady-state occupancy distribution.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

In addition, this paper is concerned with the problem of supporting multiple QoS classes according to cell loss sensitivity and cell delay sensitivity. Loss-sensitive cells are given a higher priority to access a buffer with large free space to ensure a smaller cell loss probability, while delay-sensitive cells are assigned to a smaller buffer with high access priority to the output link to meet the shorter delay requirements. We also describe the implementation of a flexible ATM switch, FLASH (flexible ATM switch with high performance). FLASH also allows for multi-rate switching, supporting arbitrary-sized logical bit pipes with varying bandwidths. A notable characteristic is that FLASH provides multi-channel switching and guarantees cell sequence integrity without additional resequencing logic in the output port processors.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

Existing approaches, such as the multicast gateway or RAS replication, have the advantage of easy implementation, but suffer from undesirable scaling properties and low performance. On the other hand, more scalable solutions, such as MARS/MCS, rely on SVCs, which are currently not available in ADSL-based broadband networks. Thus, so far there is no solution based on currently available PVC operation providing a good performance. In order to cover this need, we propose a new architecture: multicast over PVC. This architecture, besides providing good performance, gives the possibility of an easy migration towards future SVC operation.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The ITU-T recommends using the constant bit rate (CBR) for ATM service carried through an AAL2 virtual channel (VC) to guarantee voice quality. However, the traffic characteristic of AAL2 VC is variable bit rate (VBR), which is different from that of the TCP/IP data traffic at the ATM cell level by two multiplexing techniques: priority multiplexing and non-priority multiplexing. Priority multiplexing enables the transfer to TCP/IP data with the AAL2 voice quality guaranteed. Non-priority multiplexing can enable the application of VBR services through AAL2 under certain conditions, and can thus help optimize transmission efficiency in the ATM backbone network.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

Also in public networks, which serve as backbone networks for LANs, ATM technology is being introduced for high-speed and broadband communication. These situations lead to a great demand for economically and seamlessly interconnecting remote ATM-LANs via ATM public networks, which are based on the broadband ISDN user part (BISUP). This paper discusses a peer group configuration method for such an internetworking architecture that can avoid an overload of the PNNI routing processing in each peer group. The paper also proposes a method for seamless interconnection of remote ATM-LANs. In this method, complete PNNI signalling and routing is executed between a local switch (LS) in a public network and each ATM-LAN. It can also reduce the PNNI routing processing load on each public network by emulating PNNI routing and signalling between LSs.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

The proposed architecture consists of a self-routing switch which enables us to copy cell and line interfaces with a header conversion part. Our finding is that multicast can be realized by the method as follows; (1) copying cells in the switch; (2) recurring the copied cells from output ports to input ports; (3) changing the header information; (4) inputting the cells to the switch again. This proposed recursive multicast method has four main advantages. First, we can use normal line interfaces for the multicast function. Secondly, the number of lines connecting input and output can change the performance of the multicast very easily. Thirdly, this method can lower the cost of the hardware more than other approaches. Finally, it enables us to input plural cells in one physical port. In addition, this method has proved to provide an acceptable quality after experiment using a paper prototype system.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.

It is derived analytically, and confirmed by simulations, that the admission rate at which new sources can begin to transmit is a time independent constant, that depends only on the total available bandwidth and on the number of data cells between two consecutive RM cells. For low bandwidth values, this admission rate implies high access latencies. This occurs if we rely only on the congestion avoidance and fairness achievement computations of ERICA. A new procedure is proposed in order to cope with this limitation, which reduces substantially the access latencies and the maximum burst transfer delay. Simulations results both with continuous and with bursty sources are presented. A study and simulation of interactive bursty traffic is also presented.","PeriodicalId":266412,"journal":{"name":"IEEE ATM Workshop '99 Proceedings (Cat.
