1. GGF12 -Brussels draft-ggf-ghpn-opticalnets-2 Proposal for a New Draft n Grid Optical Burst Switched Networks (GOBS) n A realistic optical transport technology for the near future n Optical burst switching n Separation of the control and data planes n Brings together the complimentary strengths of optics and electronics n Allows for fine-grain multiplexing of data over a single lambda n Offers transport for a wide variety of Grid applications with user/application-initiated light path setup n Direct match of application requirements (large or medium size jobs) n Can enable network to offer fine granularity bandwidth services n Efficient : “optimal” routing decision per job n Possible near bufferless operation n Deflection routing, inexpensive wavelength conversion, increasing number of channels per fiber, small FDLs
