2. People • Andrew T. Campbell (Columbia) • Herman G.De Meer (Univ. of Hamburg) • Michael E.Kounavis (Columbia) • Kazuho Miki (Hitachi) • John Vicente (Intel) • Daniel Villela (Columbia)

3. 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

4. State of the Art • open programmable interfaces • OPENSIG, IEEE P1520 • deployment at runtime • DARPA Active Networks • multiple control architectures • Multiservice Switching Forum

5. 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

6. child virtual network differential service virtual network cellular IP virtual network physical network

7. 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

8. 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

9. network architecture #2 child virtual network kernel metabus #2 network architecture #1 life cycle services binding interface base parent virtual network kernel programming environment metabus #1 transport environment Genesis Kernel spawning

10. 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

11. L1, L2, and L3 partitioning • L1: WDM • L2: Switchlets (Cambridge Univ.) • L3: Routlets (Columbia Univ.)

14. Programming Environment • spawning networks • program their own routelets • deploy network architectures • metabus • per-virtual network software bus for object interaction • partitions distributed object space • binding interface base • supports open routelet control

16. Life Cycle Services • support profiling spawning and management of virtual networks • inherited during the spawning process • programmable upon the binding interface base and metabus

17. Profiling • topology • specified in terms of a set of parent nodes and links • architectural elements • specified in terms of routelet components, and communication protocols • resource requirements • required bandwidth • capacity classes

18. Profiling System GUI profiling life cycle server resource management spawning architecting profile database profile database profiler verifiers policy server

19. Spawning • spawning services • spawner, constructors, component storage • spawning process: • creates child routelets • binds them together through virtual links • creates a metabus • deploys life cycle services • deploys a network architecture
