High-speed WAN to wireless LAN gateway
DCFirst Claim
1. A gateway interconnecting a Wide Area Network (WAN) to a lower speed Wireless Local Area Network (WLAN) comprising:
- an adaptable cross-layer offload engine;
a data cache associated with the offload engine;
a network interface communicatively coupling the offload engine to the WAN and providing a first data rate; and
a wireless interface associated with the offload engine and adapted to communicate with a plurality of user devices within the WLAN, the wireless interface providing a second data rate that is less than the first data rate of the network interface;
wherein the offload engine is adapted to;
receive incoming data from the WAN via the network interface at the first data rate;
store the incoming data in the data cache; and
transmit the incoming data from the data cache to a corresponding one of the plurality of user devices in the WLAN via the wireless interface at the second data rate;
further wherein the gateway further comprises;
a rule check engine adapted to inspect the incoming data from the WAN based upon at least one rule prior to transmitting the incoming data to the corresponding one of the plurality of user devices in the WLAN, the at least one rule comprises at least one Digital Rights Management (DRM) rule and the rule check engine operates to identify data to be processed by a DRM function and initiate the DRM function for the identified data; and
the DRM function initiated by the rule check engine based on the at least one DRM rule, the DRM function being adapted to encode the identified data such that encoded data is transmitted to the corresponding one of the plurality of user devices within the WLAN, and provide license keys for decoding the encoded data to desired ones of the plurality of user devices having permission to consume the encoded data.

Abstract
A gateway interconnecting a high speed Wide Area Network (WAN) and a lower speed Wireless Local Area Network (WLAN) is provided. The high speed WAN is preferably connected to the gateway via a Fiber-to-the Home (FTTH) connection and associated FTTH modem. In general, the gateway includes an adaptable cross-layer offload engine operating to manage bandwidth between the high speed WAN and the lower speed WLAN. As data enters the gateway from the WAN at the high speed data rate of the WAN, the offload engine stores the data in a non-secure data cache. A rule check engine performs a stateless or stateful inspection of the data in the non-secure data cache. Thereafter, the data is moved from the non-secure data cache to a secure data cache and thereafter transmitted to an appropriate user device in the WLAN at the lower data rate of the WLAN.

17. A method of interconnecting a Wide Area Network (WAN) and a lower speed Wireless Local Area Network (WLAN) comprising:
-
receiving incoming data from the WAN at a first data rate; offloading the incoming data to a data cache; inspect the incoming data from the WAN based upon at least one Digital Rights Management (DRM) rule to identify data to be processed by a DRM function; encoding, by the DRM function, the identified data to provided encoded data; transmitting the incoming data, including the encoded data, from the data cache to a corresponding one of a plurality of user devices within the WLAN at a second data rate of the WLAN that is less than the first data rate of the WAN; and providing a license key for decoding the encoded data to the corresponding one of the plurality of user devices if the corresponding one of the plurality of user devices has permission to consume the encoded data. - View Dependent Claims (18, 19, 20, 21)
