  • Resource allocation and reclamation for on-demand address pools
    Patent number: 7788345
    Abstract: A method for on-demand management of Internet Protocol (IP) address pools includes allocating an unused IP address from a local IP address pool designated for a remote domain if a request to connect to the remote domain is received and deallocating an IP address if the IP address is released. The local IP address pool includes at least one subnet dynamically assigned from a global IP address pool. Each of the subnets specifies a contiguous set of one or more IP addresses. IP addresses are allocated using a first-assigned-subnet-first policy, wherein an IP address is allocated from a least recently assigned subnet having at least one unallocated IP address. According to one aspect, subnets are deassigned using a last-assigned-subnet-first policy, wherein the deassigned subnet is the most recently assigned subnet having no allocated IP addresses.

  • On-demand address pools
    Patent number: 7197549
    Abstract: A method for on-demand management of Internet Protocol (IP) address pools includes allocating an unused IP address from a local IP address pool designated for a remote domain if a request to connect to the remote domain is received and deallocating an IP address back to the local IP address pool if the IP address is unused. The method also includes apportioning one or more of the at least one subnet between the global IP address pool and the local IP address pool based upon utilization of the local IP address pool. The local IP address pool includes one or more of at least one subnet obtained from a global IP address pool and each subnet specifies a contiguous set of one or more IP addresses.
