....These packets carry the required header to route them in the physical network. At the destination node, the encapsulated packet of the virtual network is reconstructed and given to the virtual node. Some examples of virtual networks are ATM network carrying virtual connections over virtual paths [37] (for simpler network operation and management) IP over ATM networks (for interoperability) virtual private networks in the Internet [38] for enhanced security) and the MBONE and 6 bone virtual networks [39, 40] over the Internet (for deploying multicast services over the legacy network) ....

....the Telebase (G: Dplane) The physical connection graph and the multimedia capacity graphs are both logically represented in the BIB. At the G B interface, the XRM: G model also offers a number of network services. Among others, we mention, virtual circuits, virtual paths [1] virtual networks [6] and multicast [2] The reader is recommended to consult these references for details. 2.3 A Framework for Service Creation in the Binding Model The functionality of the G Model is one of mapping the services provided by the R Model into network services provided to the B Model at the G B ....

....(VP) based virtual networks, which is the way virtual networks are currently created in ATM networks. VP based virtual networks are normally used to simplify switching and connection acceptance control (CAC) or to aggregate traffic of different types in separate virtual networks [Friesen96] In [Chan96] VP based networks were extended by means of a concept called virtual path groups. Bandwidth can be moved between a number of VPs which are grouped together as a single entity. These approaches could be enhanced by the existence of an OSSA. An obvious application of the OSSA is a managed ....

....The emulated system module needs only minor changes when porting the software from one computer to the other; the module for real time visualization and interactive control needs no modification. Also, we use our platform in several projects where network architectures are developed and evaluated [4,13]. Experimenting with a different architecture requires mainly that we load a different emulated system module. Furthermore, we use the interactive interface module for visualizing the systems we are emulating, as well as for developing interfaces for network operators [5] In the following, we ....

Finally, the schemes described in [FOT95] and [CHA96a] can be used to multiplex calls with different source destination pairs. Depending on the type of VPN service the provider offers, the customer can choose to implement a combination of the above described multiplexing schemes in the customer control system.

A VPN is accessed via common user network physical interfaces (UNIs) A Virtual Path Group (VPG) based VPN service has been proposed to enhance customer control over the VPN [CHA96a]. The Virtual Path Group (VPG) concept has been introduced to simplify virtual path dynamic routing for rapid restoration in a carrier network [HAD89] In a VPG based VPN service, a VPG is defined as a logical link within the public network provider s ATM network. Figure 2 shows a VPG based ....
