Furthermore, if it were possible to force all devices to have unique WAN addresses, the desired number of IP addresses would not be available as there is an upper limit on the number of usable addresses in IPv4

Embodiment Construction

[0021] The following detailed description of the exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. Furthermore, the following detailed description does not limit the present invention. Rather, the scope of the invention is defined by the appended claims.

[0022]As mentioned above, it is desirable to provide mechanisms and methods that, for example, allow locally addressable devices and wide area network (WAN) addressable devices to operate on a single local area network (LAN) for use in a single interface providing access to the WAN. entry point. To provide context for this discussion, we will now compare figure 2 Exemplary combinations of devices and communication links are described.

[0023] according to figure 2 In the exemplary embodiment shown, customer premises equipment gateway (CPE GW) 40 is the access point to WAN 22 from the end user's residence. CPE GW 40 inclu...

Abstract

Systems and methods according to these exemplary embodiments provide methods and systems for allowing various devices expecting Internet Protocol (IP) addresses from potentially different locations to all operate on the same local area network. For example, a node, such as a gateway device, may receive a request for an IP address and determine whether the request is from a locally addressable device or a wide area network (WAN) addressable device. The node may then selectively provide an IP address locally or request an IP address, eg, from a WAN, based on this determination.

Description

technical field [0001] The present invention relates generally to telecommunications systems, and more particularly to methods and systems for allowing various devices expecting IP addresses from potentially different sources, eg, to operate on the same local area network. Background technique [0002] Communication technologies and uses have changed dramatically over the past few decades. Currently, copper wire technology is the primary mechanism for transmitting voice communications over long distances. With the introduction of computers, the desire to exchange data between remote sites grew for many purposes, such as those of businesses, individual users, and educational institutions. The introduction of cable television provided additional options for increasing communications and data delivery from businesses to the public. As technology continued to advance, Digital Subscriber Line (DSL) transmission equipment was introduced, which allowed faster data transmission ov...
