XQForms is the first generator of Web-based query forms and reports for XML data. XQForms takes as input (i) XML Schemas that model the data to be queried and presented, (ii) declarative specifications, called annotations, of the logic of the query forms and reports that will be generated, and (iii) a set of template presentation libraries. The output is a set of query forms and reports that provide automated query construction and report formatting in order for the end users to query and browse the underlying XML data. Thus XQForms separates content (given by the XML Schema of the data), query form logic (specified by the annotations) and presentation of the forms and reports. The system architecture is modular and consists of four main components: (a) a collection of query form controls that incorporate query capabilities and allow parameter passing from the end users via the form page. A set of query form controls makes up a query form. (b) An annotation scheme for binding these controls to data elements of the XML Schema and for specifying their properties, (c) a compiler for creating the HTML representation of the query forms, and (d) a runtime engine that constructs and executes the queries against the XML data and renders the query results to create the reports. © 2001 ACM.

The primary objective of the Multimedia Router (MMR) project is the design and implementation of a compact router optimized or multimedia applications. The router is targeted for use in cluster and LAN interconnection networks, which offer different constraints and therefore differing router solutions than WANs. One of the key design parameters is the amount of buffer space, which is closely related to the silicon area required to implement the router. In this paper, the MMR performance obtained when varying the size of the input buffers is explored. Preliminary results show that buffers as small as one flit large suffice to guarantee QoS to both CBR and VBR traffic, thanks to the use of flow control and short links. © 2001 IEEE.

We present the design and modeling of an intelligent modular switching architecture, designated MSA, for packet transport over next-generation ultra-dense wavelength division multiplexed (WDM) networks. The proposed architecture reduces the electronic processing overhead in sending the packets from source to destination. This is achieved by sending routing/forwarding information on a dedicated control channel. The control packets are processed electronically by a control processor at each intermediate node. The processing of control packets ensures that the data packets propagate from source to destination in photonic form (that is, without any processing by intermediate nodes). Due to the flexible nature of the proposed architecture it can be applied to support opaque optical networks to all-optical networks and can be used to transport IP/MPLS and ATM traffic. The performance evaluation of the proposed switching architecture shows that it drastically reduces the electronic processing overhead. Saving in the processing overhead can leverage bandwidth utilization without increasing the hardware gear cost. Furthermore, a large saving in terms of electrical-to-optical (E/O) and optical-to-electrical (O/E) converters cost per node can also be achieved.

Integrating main memory (DRAM) and processors into a single chip, or merged DRAM/logic LSI, makes it possible to exploit high on-chip memory bandwidth by widening on-chip bus and on-chip DRAM array. In addition, from energy point of view, the integration brings a significant improvement by decreasing the number of off-chip accesses. For merged DRAM/logic LSIs with on-chip cache memory, we can exploit the high bandwidth by means of replacing a whole cache line at a time. This approach tends to increase the cache-line size if we attempt to exploit the attainable high bandwidth. A large cache-line size gives a benefit of prefetching effect if programs have rich spatial locality. Otherwise, however, it will bring the following disadvantages due to poor spatial locality: 1. A number of conflict misses will take place due to frequent evictions. 2. As a result, a lot of energy will be wasted for on-chip DRAM (main memory) due to a number of main memory accesses. 3. Activating the wide on-chip bus and the DRAM array will also dissipate a lot of energy.

This paper addresses networking and traffic control problems in network systems.along with the potential for introducing soft-computing applications at supervisory control level. The incentive Stackelberg strategy control concept was introduced to the networking model that comprises subsidiary systems.of users and of network. A linear strategy is proposed for the elastic traffic problem, and results are demonstrated and illustrated via Kelly's (1997) example. The presented method is extended to the non-elastic traffic problem and results are also illustrated via a slightly modified Kelly example. Ways of employing combined analytical and soft-computing approaches and techniques in a hybrid framework have been investigated. A fuzzy-Petri-net supervisor is proposed to implement the strategic decision and control layer. Insofar obtained results are rather encouraging, and this research continues further towards possible implementation as well as some open theoretical issues. © 2001 IEEE.

This paper describes a realtime 3D sound localization algorithm to be implemented with the use of a low-power embedded DSP. A distinctive feature of this implementation approach is that the audible frequency band is divided into three, in accordance with the analysis of the sound reflection and diffraction effects through different media from a certain sound source to human ears. In the low, intermediate, and high frequency subbands, different schemes of the 3D sound localization are devised by means of an IIR filter, parametric equalizers, and a comb filter, respectively, so as to be run in realtime on a 16bit fixed-point DSP at a low frequency of 50 MHz, maintaining the high-quality sound localization. As a result of a DSP implementation and a subject listening test, this 3D sound localization scheme can be applied to mobile applications such as headphones and a handy-phone with the use of an embedded DSP. © 2001 IEEE.

Analysis of complex systems.such as hierarchically structured network systems.that are employed in modelling and analysis various aspects and issues of control and management in telecommunications is investigated. Theory of graphs and binary matrices appear to be most suitable tools for modelling the overall structure of complex systems. in general, and of systemic hierarchies, in particular. A systematic methodology has been developed for computer simulation analysis and detecting general hierarchies in communications networking as well as for synthesis of system hierarchies. This methodology is an improved extension of Warfield's technique. © 2001 EUCA.

The problem of the pricing equilibrium in multi-service priority-based networks isstudied by using Stackelberg game theory. Some concepts of the game theory were revisited first. Then, the existing results on two-user, twolevel Nash problem was reviewed briefly. Following this background, a new one-leader, two-level, two-user incentive Stackelberg strategy was derived and proved by employing the time delay involved.

The problem of networking supervision and traffic rate control in multi-service network systems.is studied by using concepts of Nash equilibrium and Stackelberg strategy under assumption of two-level system architecture. Models of users, network provider and overall system in game-theoretic setting are presented. Linear Stackelberg incentive strategies are derived for both elastic and non-elastic traffic, and verified using Kelly's example. Outlines of the two-level integrated control and supervision architecture, and of the proposed fuzzy-Perti-net supervisor are given.

The Internet explosion is driving the need for distributed multimedia presentations (DMPs), which provide multiple users with QoS-controlled multimedia services such as media distribution and virtual classroom. The provision of DMPs is usually based on the multi-cast communication. However, the jitter phenomenon over the best-effort Internet always disturbs the orchestration of multimedia presentations. Furthermore, the characteristics of multiple media streams combining the multicast delivery complicate the network and system deployment. In this paper, we describe the major considerations and techniques of designing multiple-stream multimedia presentations in a multicast communication environment. Based on the proposed control schemes, we develop a communication engine named Mcast. Mcast (i) provides the flexible authoring tool to allow users to author a multiple-stream multi-media presentation in a multicast environment and (ii) achieves smooth multimedia presentations with the well-designed temporal control mechanism. © Springer-Verlag Berlin Heidelberg 2000.
