....additional operation in the network is needed during connection setup if there are enough resources reserved in advance. The disadvantage is that resource utilization is not as efficient as a pure VC approach, and there is a trade off between signaling load and resource utilization ( 12] 13] [14]) Our approach can be seen as an intermediate step between the pure VC and the VP approach. Reservations are performed only locally, not end to end. How the resource is being used in an end to end manner is decided during connection setup time. An additional comment is that if there are ....

....to five traffic classes. Bauschert: Multihour Design of Multi Hop Virtual Path based Wide Area ATM Networks 2 1 Introduction For the single hour design of a VP network on top of a physical network a number of different methods have been proposed in the literature, see e.g. 4] 5] 6] 7] [9], 10] 11] 12] 13] and [14] Most authors, except [6] 8] 9] 11] 12] 13] and [14] assume that for each end to end traffic relation one or more separate VPs are established, and that the end to end traffic streams are not allowed to mix. This VP operation mode is denoted ....

....insufficient for the new VCC. If the increase is allowed, then increase the bandwidth and established the VCC; else, maintain the current bandwidth and refuse the VCC. Decrease the bandwidth by a specified step if it is possible, according to the VP utilization condition. As is explained in [ANE95], VP capacity allocation algorithms fall into two major categories: synchronous and asynchronous. Synchronous algorithms update the VP capacity in real time based on the observed demand for VCC establishment. In this context, the bandwidth of the VPs can be expanded or contracted at call arrival ....

....configurations based on the Virtual Path (VP) concept in order to facilitate and speed up admission control and routing. Provision and appropriate dynamic management of VPs can maintain a high level of utilisation, while at the same time reduces the steps to be taken by CAC and routing (see e.g. [5], 6] 7] Moreover, Virtual Paths enable the provision of logically separated Virtual Networks on the same physical infrastructure. Different virtual networks may belong to different Service Providers, for example. Although NRM mechanisms reside in the management plane from a computational ....

....with network management. Agents have not widely applied to network control yet. Nevertheless, several efforts have addressed issues related to network resource management (NRM) Although network resource management mechanisms reside in the management plane from a computational viewpoint [8] [9], they are tightly coupled with network control strategies. This is because they operate in considerably shorter time scales than network planning and provisioning tasks. Network control based on Intelligent Agents is the main topic of rest of this paper. In particular, the paper presents work ....

....it, install and manage a virtual network. This process reduces to reserving resources in the network and constructing an image of these resources on a repository under the control of the service management system. Virtual networks are typically realized using resource partitioning algorithms [5]. Such networks provide some degree of customer control. They do not support, however, different signalling and service management systems. This is made possible by switchlets [31] Switchlets encapsulate a subset of physical switching resources. A set of switchlets on different switches combine ....

....For example the parent might be a decentralized architecture controlling the resources of the virtual network whereas the child is a centralized one. 5. 1 Engineering Network Architectures Building on our extensive experience with the design and implementation of virtual private networks [3] [5], 13] 17] we will investigate representations of virtual networks as switchlets as services of the network architecture. The goal here is to exchange the management based creation of the virtual network with a control based one. The latter would be executed automatically by the signalling ....
