Iowa State University researchers have developed a novel routing, slot, and wavelength assignment (RSWA) technique called single-slot advance reservation (SSAR).  This method allows for large datat transfer over Grid networks

This new continuous advance reservation process that checks all available time slots to prevent delays in transmission. This approach avoids fragmentation as a result of delayed resource allocation. The method allocates wavelength path or light path or channel (all three are used synonymously), reducing unnecessary blocking and improving efficiency.   This two-step process allocates a channel when the request is being served. This single slot advance reservation (SSAR). SSAR also simplifies control as detailed later on.   The patent is available for non-exclusive license.

• Efficient scheduling

• Allows for transmission of large data sets
