keynote 1 - Self-organizing Virtual Private Networks and Applications
Abstract:
Virtualization technologies have witnessed a renaissance in the recent past, fueling the development of Infrastructure-as-a-Service (IaaS) systems that provide the foundation for on-demand provisioning and cloud computing. While virtual machine (VM) technologies decouple and isolate processing within the scope of a single physical computer, virtual networking provide the basis for decoupling and isolating communication among virtualized resources, enabling cloud infrastructures that can seamlessly span geographically-dispersed data centers (possibly across multiple institutions), and providing end-to-end private communication among peers constrained by network address translation (NAT) and firewall devices which are increasingly common in the Internet. In this talk I will overview research efforts from my group on the use of self-organizing peer-to-peer (P2P) techniques to address challenges in network virtualization, where the P2P overlay and virtual network devices are used as a basis for capture, encapsulation, and resilient and scalable routing of virtual network packets, as well as in the support for the assignment of network addresses and their mappings. In particular, I will overview the IP-over-P2P (IPOP) system architecture, virtual appliances for distributed computing on virtual private clusters across multiple cloud infrastructures, and some of its applications in projects including FutureGrid.
