Proposal for Grid Optical Burst Switching Networks (GOBS): Advancing Optical Transport Technologies

This proposal outlines the development of Grid Optical Burst Switched Networks (GOBS) as a cutting-edge optical transport solution for varied Grid applications. By integrating robust optical and electronic components, GOBS promises enhanced fine-grain multiplexing and bandwidth granularity, efficient routing, and near bufferless operations. It prioritizes user/app-initiated light path setups and Quality of Service (QoS) provisioning, while coexisting with existing control protocols. With collaboration from leading experts, this initiative aims to revolutionize optical networks for both large-scale and smaller-scale users, ensuring adaptability and security in a dynamic photonic ecosystem.

  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
