....control of resources like the processor in the more general operating system environment. The reserve system would make it possible to address resource reservation issues in general end systems, extending H. Zhang s work on resource reservation within the network and its routers. Anderson et al. [4] describe a Session Reservation Protocol (SRP) which reserves resources along the route of a connection to ensure a particular bandwidth and delay for the connection. This protocol provides resource reservation at routers for predictable network performance. The reserve system would make it ....

The message generation process is specified in terms of a linear bounded arrival process, a model which was first proposed by Cruz [12] This model has also been adopted by Anderson and others [1, 4] for continuous media applications, and some of the terminology given below is from [1] The arrival process has the following parameters: maximum message size Smax (bytes) maximum message rate R max (messages second) maximum burst size B max (messages) The model includes the restriction that, ....

Network model We consider a network of arbitrary topology supporting real time communication using a con Page 3 nection oriented reservation scheme [Fer 92, And 91, Zha 95] That is, before sending data at the desired QoS, a connection first has to be established from the source node to the destination node. Each node in the path source destination should verify that it has enough available resources to open the new connection. This means that each node ....

The definition of such a model for CINEMA is for further research. 6 Related Work In the past, several protocols have been designed to support resource reservation between two endsystems across network links. SRP [AHS90] ST II [Topo90] and RSVP [ZDE 93] were designed to support reservation for multicast communication between a source and many sinks (SRP, ST II) or between many source many sinks (RSVP) by assuming that no processing has to take place between sources and sinks. Reservation was based on ....

To manage the network resources, the DASH project developed the Session Reservation Protocol (SRP) SRP operates by allowing applications to reserve capacity at each host in an IP internetwork, and then use standard IP protocols to transmit data [2]. Another protocol based on resource reservation for adding QOS guarantees to IP networks is the ST II protocol [52] An implementation of this protocol for Token Ring networks was developed by researchers at the IBM European Networking Center as the foundation of the Heidelberg Transport System ....

Certain applications, such as voice, produce packets at the given rate only for a fraction of the time ([4, 12]) The ON OFF model[13, 14] is used to characterize a data stream. In this model two distinct periods are considered. During the ON period packets arrive deterministically at intervals of T milliseconds. No packets arrive during the OFF period. The ON and OFF periods alternate and are distribute ....

....some capacity to handle multimedia data, but the necessary resources are very limited. Especially when dealing with large audio and video streams, many systems are constrained in the quantity and quality of streams they can support. This situation has been depicted as the window of scarcity [Anderson et al. 1990b] While a certain class of applications lies within this window, a system needs to allocate and schedule its resources carefully in order to provide the desired service (see Figure 15.2) Before the window of scarcity is reached, a system has insufficient resources to execute the relevant ....

The loss characteristics are defined by the total acceptable number of losses over a certain interval and the maximum number of consecutive losses. There are many alternatives for expressing each parameter group. In SRP [Anderson et al. 1990a] the burstiness of a stream is given by a maximum workahead parameter that defines the number of messages a stream may be ahead of its regular arrival rate at any point in time. In [Ferrari and Verma 1990] a worst case delay bound is given: if the system cannot guarantee to transport data within ....

....Government 2 underlying system that maintains the QoS requirements negotiated at the establishment phase [HAF95c] regardless of the fluctuation in system load. A number of schemes have been proposed to provide performance guarantees, at the communication level, based on resource reservation [FER90, ZHA90, AND90, TOP90]. A real time service may offer either hard guarantees or only soft guarantees which means that some target QoS is agreed, however, without any real guarantee. Regardless of the type of guarantee, protocols for QoS adaptation are required to deal with QoS violations since temporary overload ....

....the resources required by the new request does not exceed the capacity of the component. The request admission control processing depends on the scheduling mechanisms used by the components. An example of admission control test for communication systems, e.g. network nodes or LAN, can be found in [FER90, AND90, KAL91, CHO94]. During the active phase, measurement of the QoS parameters may be performed at each component level to check whether the component is violating its commitments. In the case of violation, actions must be taken by the QoS manager trying to keep the negotiated end to end QoS, such as those ....

To support these performance requirements, new solutions have been proposed that provide guaranteed performance or real time services in packet switched networks [6, 13, 18, 1, 2, 11, 7, 3]. These solutions are usually connection oriented, and require fixed routing and resource reservation on a perconnection basis. In these solutions, resource allocation and routing decisions are made at the time of connection establishment, based on the resource availability and realtime network ....

In fact, whenever the load conditions of the network change, the quality of service provided changes as well; this calls for adaptive clients, i.e. clients capable to tolerate and compensate fluctuations, and even disruptions, in the network s service. In the SRP protocol [1], clients can specify their requirements by using three traffic parameters and one performance index. The first three are respectively the maximum message size, the maximum message rate, and the maximum burst size. The performance index is a delay specification, given as a target, and a maximum ....

More specifically, four main performance oriented QoS parameters [Fer 92, And 91, MIL 94] have been identified for specifying distributed MM application requirements: delay, jitter, loss rate, and throughput. We note that the jitter is derived from the delay parameter; jitter is defined as the delay variation. Furthermore, it was reported that the most suitable location to ....

This separation between setup and transfer suggests that establishment (and teardown) be done by a control protocol distinct from the data delivery stack. This solution is not universally preferred (as in the cases of ST II [5] and SRP [14]) but it has the advantage of allowing us to develop the control and data delivery protocols separately, in a more easily manageable, testable, maintainable, and portable fashion 3 .

While there are many different methods of bandwidth management they all fall into one of two categories: static or dynamic. Static resource management approaches as suggested in [1, 4, 8] do not reflect the inherent dynamic nature of user requirements and the network state, which may change during the lifetime of the connection.

The execution of a reservation request implies the allocation of the corresponding resources to the requesting application. The QoS agent may run admission tests [Fer 92, Top 90, Han 91, And 91] in order to determine which QoS values can be currently promised, or in order to determine whether a given service request can be granted.
