....rate of 20 MBytes sec. At the time of our first prototype s implementation, interfaces for ATM networks were not available, and therefore we used the interface for the ORBIT network. ORBIT is an optical network based on buffer insertion ring approach, and supports speeds up to 640 Mbits sec [3]. A separate network interface also gives us the flexibility to change the network interfaces to allow our server to be used in different networks. ORBIT software available for workstations supports the Internet protocol suite. The control processor is an off the shelf ARTIC 960 card running a ....

Status and performance We implemented a testbed comprising of our video server prototype, the ORBIT 620 Mbit sec. optical ring network [3], and a pair of multimedia stations. The ring network was programmed to circulate all streams transmitted from the server, and each multimedia station could select any two streams and display them in two windows. The video server and the testbed were operational in November 1994. With essentially ....

....servers, etc. In each domain, the network aspects of the flow management resource reservation function are realised as a single network server which we call a resource server [1] A number of architectural choices were possible for resource server realisation. One proposal in the literature [17] advocates a fully distributed architecture capable of making resource management decisions such as flow admission control at any node. This has the advantage of reducing connection setup time because all the required state is available locally. However, corresponding disadvantages include the ....

....with minimal overhead. This research was conducted in context of the spanning tree hardware structure of IBM Networking Broad Band Services (NBBS) architecture announced recently, as well as by the tree broadcast in experimental predecessors for NBBS named PARIS, described in [17] and plaNET [18]. In fact, the results of the research described here influenced the development of the multicasting facility in NBBS. Specialized hardware is necessary but not sufficient to provide high speed multicast. Administrative, network control, transport, and application layer issues need to be addressed ....

....good example. Directory services must be provided somewhere in the network so that translation between different name spaces (in particular the ones used by ATM) takes place. Because the CP maintains the network topology it would be natural for such a function to be implemented within the CP ( 10][11][12] 3.2 CP data structures Every CP maintains a version of the hardware routing table of the switch that it controls. In general, the CP tables need not be an exact replica of the hardware table, but they should contain all the information derivable from the hardware table, plus some extra ....
