Presentation Transcript

  1. Proposal for a New Draft • Grid Optical Burst Switched Networks (GOBS) • A realistic optical transport technology for the near future • Optical burst switching • Separation of the control and data planes • Brings together the complimentary strengths of optics and electronics • Allows for fine-grain multiplexing of data over a single lambda • Offers transport for a wide variety of Grid applications with user/application-initiated light path setup • Direct match of application requirements (large or medium size jobs) • Can enable network to offer fine granularity bandwidth services • Efficient : “optimal” routing decision per job • Possible near bufferless operation • Deflection routing, inexpensive wavelength conversion, increasing number of channels per fiber, small FDLs

  2. Proposed Outline for a New ghpn Draft • Next generation optical Grids • i.e. not only for l, escience, data intensive users • The fundamental premise of OBS for Grid applications • A dynamic photonic network for the large and the smaller user • Grid-OBS (GOBS) network elements • Technology requirements • Switch architecture & control • Control plane and signalling considerations • Protocols for end-to-end user/application initiated OBS connections • i.e. Just-In-Time (JIT) control and signalling protocol • Interoperation with existing controls i.e. GMPLS

  3. Proposed Outline for a New ghpn Draft • Definition of Grid services for optical burst switching • Interaction with Grid middleware • SLAs in the OBS networks  • QoS provisioning • Application layer consideration • Physical layer considerations • Addressing blocking • Advanced network concepts and solutions • i.e. programmable, active, self organised GOBS • Security
