Device, system, method and computer readable medium for fast recovery of IP address change
First Claim
1. ) A device to provide communication between a wide area network and a short distance wireless network, comprising:
- a memory to store a first wide area network address, a second wide area network address and a router software component;
a processor coupled to the memory; and
, wherein the processor and router software component transfers a first plurality of packets between the device and the wide area network using the first wide area network address, and wherein the processor and router software component discontinues the transfer of the first plurality of packets responsive to receiving the second wide area network address and transferring a second plurality of packets between the device and the wide area network using the second wide area network address.

Abstract
A device, method, system and computer readable medium allows for a fast recovery of a communication connection in response to a newly assigned Wide Area Network (“WAN”) Internet protocol (“IP”) source address. In an embodiment of the present invention, a device provides communication between a WAN and a short distance wireless network. The device comprises a memory to store a first and a second WAN address for the device and a router software component. The processor and router software component transfers a first plurality of packets between the device and the wide area network using the first wide area network address. The processor and router software component discontinues the transfer of the first plurality of packets responsive to receiving the second wide area network address and transfers a second plurality of packets between the device and the wide area network using the second wide area network address. The second newly assigned WAN address may have been assigned by the WAN after a disconnection of communication between the device and a server in the WAN. In an embodiment of the present invention, the router software includes a plurality of private IP addresses for respective terminals, in the short distance wireless network, associated with the WAN IP address. In an embodiment of the present invention, a Point-to-Point (“PPP”) connection or Transfer Control Protocol (“TCP”) connection is discontinued and then initiated in response to a newly assigned WAN IP address in order to quickly recover a communication connection between terminals in the short distance wireless network and the WAN.
