g e n e s i s Motivation deployment of network architectures: ad-hoc in nature and costly no systematic exploration of the “network design space” virtual networking isolation and privacy quality of service support

g e n e s i s State of the Art open programmable interfaces OPENSIG, IEEE P1520 deployment at runtime DARPA Active Networks multiple control architectures Multiservice Switching Forum

g e n e s i s Spawning Networks new class of programmable networks capable of creating new architectures on-the-fly automate a “life cycle” process enabling technology: the Genesis kernel

g e n e s i s cellular IP virtual network child virtual network differential service virtual network physical network

g e n e s i s Life Cycle profiling Captures the “blueprint” of the virtual network spawning allocates resources, sets up topology, binds transport, control, and management management architecting resource management

g e n e s i s Design Principles separation transparency of operation between parent and child networks nesting child networks, can be parent of their own children inheritance architectural components provisioning characteristics

g e n e s i s Genesis Kernel spawning metabus #2 network architecture #2 child virtual network kernel transport environment metabus #1 binding interface base life cycle services network architecture #1 parent virtual network kernel programming environment

g e n e s i s Transport Environment consists of programmable virtual nodes called “routelets” routelets : interconnected via “virtual links” share parent routelet resources may coexist in the same physical node virtual links : abstractions of resource partitions

g e n e s i s L1, L2, and L3 partitioning L1: WDM L2: Switchlets (Cambridge Univ.) L3: Routlets (Columbia Univ.)
