DOE Office of Science Workshop on

Scalable and Secure Control-Plane Technologies for Hybrid Networks

   February 8, 2006, Albuquerque, NM

Background and Motivation

Recent advamces in network provisioning and control-plane technologies have enabled us provision on-demand and in-advance dedicated channels at various layers of IP stack. In general, such channels provide unimpeded bandwidth to support large data transfers and stable control flows needed for comutational steering and instrument control. In IP networks such channels may be provisioned using Multiple Protocol Label Switching (MPLS) technologies typically at layer-3. In certain other networks, such channels are provisioned at layers 2 or below using various technologies such as Generalized MPLS (GMPLS), TL1, and CLI. There are cost-benefit trade-offs in provisioning and utilizing the channels of various levels both from application and infrastructure perspectived. While a layer-3 channel requires relatively small enhancements to existing IP insfrastructures, layer-2/1 channels offer lower cost and smoother connectivity to file systems and supercomputers.

It is generally expected that future DOE large-scale science applications will be supported by hybrid high-performance networks that provide both production-level shared-IP connectivity and on-demand and in-advance scheduled dedicated channels at certain layers. Such networks require scalable, secure and integrated control-plane technologies to realize the needed capabilities and perforamance. Furthermore, they require graceful and effective intefacing of the shared-IP and dedicated channel components of the hybrid networks. In addition, such hybrid netwokrs must peer with other networks which themselves may be packed-switched, circuit switched or hybrid.

Workshop Overview

This workshop is intended to address the control-plane aspects of present and future DOE Office of Science networks in general and the current ESnet and UltraScienceNet in particular. The goal is to identify and assess the technical aspects of control-planes for such networks, and develop a roadmap for development and integration of the appropriate technologies. In particular, a detailed plan is to be identified to peer the MPLS-based control plane of ESnet OSCARS bandwidth reservation system with the centralized bandwidth reservation system of USN.

The participation is this workshop is by invitation only.
