This concept concerns a new system for monitoring leases in a networked environment. Some network services, such as databases, backup, video-on-demand, etc., involve the allocation of resources. These resources include disk space in the case of the database and backup services, network QoS in the case of video-on-demand, and the control of camera in the of face detection services. The implementation of these services can be greatly simplified if it is based on a generic lease service, which controls the allocation of the resources and negotiates the leasing parameters (eg 5 GB of disk for X minutes, the total control of the camera for Y seconds, transmission of video V with a bit rate B, etc). This generic lease service can be registered in a service lookup database, such as UDDI (, so that services that require the allocation of resources can find and use it. In this way the same generic lease service can be reused among several applications. Figure 1 illustrates this architecture. 1. Find Database lease service Backup
