To the network architect the creation process is ad-hoc in nature, based on hand crafting small-scale network prototypes that evolve toward wide scale deployment. We envision a different paradigm where 'spawning networks' are capable of profiling, spawning, architecting and managing distinct virtual network architecture on-the-fly. This paper provides an overview of a virtual network kernel and its life cycle of spawning virtual networks, and focuses particularly on the role of resource management of virtual networks. We describe virtuosity, a virtual network resource management system that minimizes the complexity of handling multiple spawned virtual networks that operate over multiple timescales. Virtuosity is driven by per-virtual network policy exerting control and management over multiple spawned virtual networks (characterized by a set of resources) and their spawned architecture (defined as a set of interacting controllers objects) by dynamically influencing the behavior of resource controllers over slow timescales. Virtuosity provides a foundation for the management of virtual networks and forms an integral part of the virtual network kernel being developed within the Genesis project at Columbia University.","PeriodicalId":435117,"journal":{"name":"1999 Seventh International Workshop on Quality of Service.

Crowcroft","doi":"10.1109/IWQOS.1999.766472","DOIUrl":"https://doi.org/10.1109/IWQOS.1999.766472","url":null,"abstract":"IP is often referred to as the waist of the hourglass, because of the simple model the Internet provides packet level communication compared to other approaches (e.g., FR, X.25 or B-ISDN), but runs over a complex plethora of links and switched networks, and is used by a firmament of application and transport protocols. The ever increasing demand for capacity is pushing us past the 40 Gbit/s barrier, and towards the terabit link. Dense mode WDM offers 128 wavelengths at tens of gigabytes per wavelength. However re-tuning takes geological epochs compared to IP packet switching, or flow switching, or even QoS routing time frames. The problem resembles that of IP over ATM or other virtual circuits, but this may be misleading: what is needed is a novel approach to a network architecture, that avoids the same design flaws and pitfalls we have been forced into in IP over ATM (including MPLS). This paper briefly describes why these approaches are misled, and attempts to outline an approach based on network edge packet sorting and scheduling, which may allow us to use pure optical core networks without sacrificing the flexibility of what we might call legacy electron-datagram services.","PeriodicalId":435117,"journal":{"name":"1999 Seventh International Workshop on Quality of Service.
