Abstract:

While the existing license management systems are only suitable for the LAN environment, a novel grid middleware, which is named LicTraveler, is devel oped for global license sharing across various domains. The two-leveled hierarchical architecture allows both autonomous local services and cooperative   global services. It provides strong security and flexible reservation and quota policies for licensing activities. Flexible license distributing and sch   eduling policies are also provided. Experiments show that LicTraveler helps corporations reduce their redundant investments and promote license efficien cies as much as 50%.

Key words: grid, software sharing, floating License, LicTraveler
