Abstract
A method and apparatus for dynamic host configuration protocol lease time determination by receiving at a first dynamic host configuration protocol device, a message requesting allocation of an IP address to a client, and allocating to the requesting client a relatively short lease time, if a second dynamic host configuration protocol device does not contain the requested IP address lease.
Claims16
A method, comprising:
- receiving at a first dynamic host configuration protocol (DHCP) device, a message requesting allocation of an IP address to a client;
- and
- allocating to the requesting client a lease time less than time period T if a second DHCP device has not obtained the requested allocation of said IP address.
An apparatus, comprising:
- a first DHCP device, for receiving messages from a client and issuing lease times to said client in response to the messages, the messages requesting allocation of an IP address to a client;
- a second DHCP device, for receiving IP address leases from a wide area network associated with said requested IP addresses;
- a memory for storing communications parameters and instructions;
- and
- a processor, upon executing said instructions, configured to:
- receive at said first DHCP device, a message requesting allocation of an IP address to a client;
- and
- allocate to said client a lease time less than time period T, if said second DHCP device has not obtained the requested allocation of said IP address lease.
Computer-readable medium for storing a set of instructions, wherein when said set of instructions is executed by a processor perform a method comprising:
- receiving at a first dynamic host configuration protocol (DHCP) device, a message requesting allocation of an IP address to a client;
- and
- allocating to the requesting client a lease time less than time period T if a second DHCP device has not obtained the requested allocation of said IP address.
An apparatus comprising:
- means for receiving at a first dynamic host configuration protocol (DHCP) device, a message requesting allocation of an IP address to a client;
- and
- means for allocating to the requesting client a lease time less than time period T if a second DHCP device has not obtained the requested allocation of said IP address.
