SYSTEMS AND METHODS FOR SHARING OF RESOURCES

A method for allocating access to a shared limited resource among a plurality of users who require access to the resource, the allocation being made such that each user is granted access to the resource at a minimum guaranteed rate associated with each user and such that the resource is available for use by any user exceeding its minimum guaranteed rate only if the resource is available, the method comprising the steps of: assigning tokens to each user at a rate determined by the minimum guaranteed rate associated with each user; storing tokens assigned to each user in a bank associated with each user, each bank having a finite capacity associated with each user; storing tokens assigned to a user whose associated bank has reached its capacity in a bank assigned to another user whose bank is below its capacity; and allowing a user requesting access to the resource to have access to the resource if the user has a predetermined number of tokens in its associated bank and otherwise denying access to the resource.
