  1. broadband kernels: making nets as programmable as PCs Programmable broadband, Internet and mobile nets

  2. QOS management control programmable nets signaling transport making networks more programmable net state distributed systems technology broadband kernel

  3. What is a broadband kernel? • motivation • to facilitiate the easy creation and introduction of new multimedia services with end-to-end QOS guarantees into broadband networks • concepts • “open programming networking” environment • what do we by open? • what do we mean by programmable? • QOS explicitly modeled and programmable • broadband kernel service • multimedia services use broadband kernel

  4. new services and applications programming model service abstractions services and applications network broadband kernel services middleware layer binding interface base (BIB) degree of programmability programmingmodel QOS abstractions QOS abstractions mobile networks broadband (ATM) NG Internet

  5. simple taxonomy of programmable Nets Broadband kernel Active networks -new services with QOS -accelerate introduction of new service, protocols, etc. -signal and data separate -signal and data integrated -CORBA-based -inject customized code into nodes Mobile code-based Switchlets-based Capsules-based Objects-based mobiware xbind Conservative moderate radical

  6. network objects with QOS

  7. approach • CORBA-based signaling • open and flexible device control • programmable ATM switches/routers • mobile capable switches/routers • base stations, and mobile and fixed devices • programmable multimedia devices • transports • native ATM transport • active and adaptive transport

  8. programmability CORBA-based Signaling Client Application Object Implementation BIB CORBA IP Physical
