SAVI Overview SAVI: Smart Applications on Virtual Infrastructure NSERC Strategic Network Grant $1M per year from NSERC for 5 years (July 2011-June 2016) Additional cash and in-kind from industry partners National collaborative research project (next-gen Internet) PI: Alberto Leon-Garcia (ECE, U of Toronto) Co-investigators: about 12 from across the country U of C participants: Majid Ghaderi (and selected grad students) Carey Williamson (and selected grad students) Sharing $40K/yr for SAVI-related research (Wireless/Edge) 3

Virtualization is the Key The term virtualization refers to a conceptual separation between the logical view of a resource and the physical implementation of that resource (e.g., abstraction or indirection as used in CS) Simplifies management/sharing of resources Enables flexible/efficient/scalable use of resources OS Examples: CPU, memory, disk, file systems NW Examples: VC, VLAN, VPN, subnets, DNS, SDR Cloud Examples: VMs, servers, virtual data centers 4

SAVI Goals The main goal in SAVI is to push the limits of virtualization in networking and closely related areas Any resource can be virtualized and shared Examples: virtual routers, virtual APs, Innovative applications can be built from these (virtualized) resources, once they are made available Flexible, on-demand resource management Current: Software-Defined Networking (SDN) Near Future: Software-Defined Infrastructure (SDI) Far Future: Software-Defined Everything (SDE) 5
