Summary:
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

Development Stage:
Description:
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.

Advantage:
• Efficient scheduling
• Allows for transmission of large data sets

Application:
Computer networking, data transmission, broadband communications
