“…Together with the emerging IPv6 protocol (Gilligan, 1995), RSVP will form the basis for the Integrated Services Internet and for Internet-11 with its gigabit links. Higher-level quality of service architectures enable a further abstraction of QoS specifications, facilitating the implementation of QoS-aware applications (Campbell, 1994;Vogel, 1995). However, the reservation approach of RSVP and related protocols attempts to reserve resources just at the point in time when they are actually required.…”

Existing reservation protocols such as RSVP implement so-called immediate reservations (lmRe) that are requested and granted just when the resources are actually needed. This paper describes the design, implementation and evaluation of a novel advance reservation protocol. Its major property is that resources are reserved well in advance to the actual usage phase. This way, the probability of resource availability can be increased, and network utilization can improved. Specific aspects covered in this paper are the mapping of ReRA (resource reservation in advance) onto RSVP, the evaluation and selection of an appropriate call admission control strategy, the internal management of advance reservations, the mapping of the approach onto A TM, as well as its implementation and evaluation.

“…For example, the definition used within the ODP framewerk appears to be oriented towards the higher Ievels. It defines QoS as a set of qualitative requirements on the collective behaviour of one or more objects (Vogel, 1995). This raises the important issue of collaboration among different objects.…”

The rapid development towards networked multimedia applications Ieads to new and high requirements on the network as weil as on the systems involved. Especially guaranteed Qualityof-Service (QoS) is required for certain applications with isochronous data streams or with highly interactive characteristics. Therefore, an integrated systemwide QoS management is needed. Among others, issues such as mapping of QoS parameters between fundamentally different Ievels of the system (user, application, network) and QoS monitoring are very important. This paper presents a framework for QoS management. Requirements of networked multimedia applications as weil as several QoS management issues are discussed. Moreover, a QoS monitor as part of the QoS framework and its implementation J.s presented.

“…In the field of control architectures, there are many definitions of quality of service. From the viewpoint of processing, QoS represents the set of both: quantitative and qualitative characteristics of a distributed system needed to achieve the functionality required by an application [9]. From the communication viewpoint, QoS is defined as all the requirements that a network must meet to message flow transport [10].…”

Abstract. This paper presents an implementation of a middleware architecture to control distributed systems. The main objective is providing a QoS level between the communications layer and the control layer. This architecture is based on the use of a hierarchical communications structure called "logical namespace tree" and a structured set of control processes interconnected, called "logical sensors graph". This architecture is named Frame Sensor Adapter Control (FSA-Ctrl). In this architecture communication layer and control layer can manage the QoS policies. The communication layer is based on the Data Distribution Service (DDS), a standard proposed by Object Management Group (OMG). Control layer is derived from the Sensor Web Enablement (SWE) model proposed by Open Geospatial Consortium (OGC). Middleware components use messages queues to manage components QoS requirements. By means of QoS policies, control components can take important decisions about distributed questions, like components mobility or information redundancy detection.
