  1. Welcome ESCC & Internet2 Joint Techs Workshop Madison, Wisconsin.July 16-20, 2006 Network Virtualization & Hybridization Thomas Ndousse DOE, Office of Science

  2. The Internet: The Evolving Global Network Infrastructure Real-time Traffic Data Traffic burst Traffic Video Streaming • The Internet – One of the greatest achievement of the 20-th century • The Internet must evolve, innovate, and scale to to meet increasing ubiquity • Ossification – Difficult to introduce new innovations in the network voice Traffic IP T1 ATM Ethernet SONET Satellite DWDM wireless Soliton

  3. The Internet: then, Now, & tomorrow Simple System Ubiquitous System Complex System

  4. Emerging Network Virtualization • Network Virtualization • Virtualization attempts to solve the ossification problem by allowing multiple virtual networks to co-exist within a shared infrastructure • Why? • De-ossification - expand or eliminate the neck of the IP hourglass • Attempt to understand and manage large-scale network complexities • Stimulate research and innovations through deployment and testing of disruptive network technologies • Accommodate the requirements of diverse types of applications, especially high-end science applications

  5. Overcoming Ossification and Complexity • PlanetLab – Larry Peterson, Scott Shenker, Jon Turner • A geographically distributed platform for deploying, evaluating, and accessing planetary-scale network services • A blueprint for future Internet • Platform for testing disruptive technologies before adoption • GINI(Global Environment for Networking Innovations ) • Beyond existing packet and circuit switching technologies • Building security into network architecture and protocol primitives • Towards a network science - Network architecture theories, the Internet as a complex system

  6. Topological Representation of Network Virtualization (PlanetLab) Source: PlanetLab and NSF GENI Workshop Report

  7. Expectations of Network Virtualization • Each virtual Net (Vnet) is an independent network that operates in a protected partition • Inter-Vnet communication is allowed at the shared node • Vnet #0 is designated as the network that performs the control and management • Vnets can acquire and release resources to the main network infrastructure (dynamically?) Layer 2 Vnet #3 Layer 3 Vnet #n Main Network Net #0 Control Net Layer 4 Vnet #2 Layer 2 Vnet #1

  8. Layer 3 Layer 2 Layer 2 Layered Approach to Network Virtualization Vnet #1 Vnet #2 Vnet #3 Vnet #4 Layer 5, 6, 7 Layer 4 Layer 3 Control and Management Layer 2 Layer 1 Layer 1

  9. Hybrid Network: Minimum Implementation of Network Virtualization Main Network (IP-Based) Main Network (IP-Based) Vnet (Circuit-Based) Vnet (Circuit-Based) • Hybrid Network Model 1 • Vnet is carved from the main backbone network • Resources can be exchanged between the Vnet and the main network • Hybrid Networks Model 2 • Vnet and the main network are two independent networks • No resource exchanged between the two networks

  10. Hybrid Network Node Functions and Capabilities E e-GMPLS:GMPLS with scheduling and reservation extensions D C Routing Functions Switching Functions A F G B Data Plane Technologies: MPLS, Layer 2 VLANs, Layer 3, SONET, WDWM

  11. Peering Issues of Hybrid Networks E E D D A C F A F C A G B G B

  12. Hybrid Network Research and Engineering Issues Hybrid Network Theory and Foundation • Hybrid network architecture • Hybrid network node capabilities, functions, signaling, and control • Hybrid network traffic engineering and network management Inter-Domain Issues for Hybrid Networks • Hybrid network taxonomy – Common terminologies and capabilities • Multi-domain control plane: engineering, policies, authentication • Hybrid network security issues: vulnerabilities of control planes, Circuit authentication • Hybrid network monitoring, performance measurement and prediction

  13. Inter-Agency View of Network Ossification & Virtualization • Ossification is a problem across all federal agencies (DOE, DARPA, NSA, etc) • GENI is NSF’s view of the problem – A multi-agency approach to the problem is critical • Contribution from the science community is especially critical • LSN Workshop – The Future of Internet and Experiential Facilities Design, July 24-25, 2006
