“…The service management structure is an extension of the one presented in [21]. The extension consists not only of an obvious adaptation to the parallel MAC architecture, but also of redefinition of the functions of the various elements in the management structure to make it more modular and flexible towards the development and evolution of the services offered or required by users.…”

“…The Service Management, in accordance with the specifications made in [20], is organized into hierarchical levels sharing a single control plane. Each layer controls the layer below it and is controlled by the one above it [21], and is made up of a certain number of processes operating on the so-called "management objects" which correspond to functional entities of the network (e.g. convergence blocks) or network resources (e.g.…”

“…The Control Plane, in fact, deals with the reception, processing and sending of reports. It does not perform "active" actions on network resources or, in general, on management objects, and is made up of a 'QOS Monitoring' process which controls and monitors service performance [21].…”

Abstract. Medium access control protocols based on a dual bus topology, such as the IEEE 802.6Distributed Queue Dual Bus (DQDB), are usually considered to be highly satisfactory for high speed networks. But the DQDB can only partly support new sophisticated multimedia services, mainly because the increase in the channel bit rate needed to meet the greater bandwidth requirements causes an increase in unfairness in the medium access control of the nodes. In this paper the authors propose a Gigabitls Metropolitan Area Network (MAN) based on the IEEE 802.6 DQDB protocol and multichannel connectivity on optical fiber, by means of Wavelength Division Multiplexing (WDM). They present a parallel node architecture in which N DQDB subnodes parallelly access N WDM channels.Channel access at each node is regulated by N finite state machines operating independently and sharing a single MAC Convergence Functions (MCF) block for the segmentation and reassembly of user information. On the basis of the MAC architecture proposed, B network management structure is also presented, with particular reference to the Quality of Service monitoring processes. The proposed architecture is more modular than the DQDB standard; it provides greater fairness and better access delay and allows efficient management of service classes with priority.
