A technique involves exchanging DHCP relay agent information with a DHCP server. In particular, the technique involves receiving a DHCP message en route from a DHCP client to the DHCP server. The DHCP message includes (i) a non-option portion having a client identifier identifying the DHCP client and (ii) an option portion having first relay agent information added to the DHCP message by a first relay agent. The technique further involves modifying the option portion of the DHCP message to simultaneously include both the first relay agent information added by the first relay agent and second relay agent information from a second relay agent. The technique further involves sending the DHCP message with the modified option portion to the DHCP server. Accordingly, the DHCP server is capable of receiving relay agent information from multiple relay agents and assigning an address to the DHCP client based on this input.

A technique controls operation of a BRAS device. The technique involves extracting encapsulation information from a communications exchange between a CPE device and an external server device (e.g., a DHCP server). The communications exchange passes through the BRAS device and a DSLAM device. The technique further involves storing the encapsulation information in local memory of the BRAS device, and controlling a flow of a downstream communication passing through the BRAS device and the DSLAM device toward the CPE device based on the encapsulation information stored in the local memory of the BRAS device. Accordingly, the BRAS device is well suited for performing ATM overhead accounting as well as shaping and policing downstream traffic.

摘要:
Methods and apparatus are provided for transmitting incursion alerts to a plurality of in-flight aircraft in accordance with preconfigured pilot preferences. The apparatus comprises a data store module containing data sets against which the pilot preferences are evaluated during flight, including weather, airspace and flight restrictions, ground delay programs, and air traffic information. The apparatus further includes a flight path module containing route and position information for each aircraft. An incursion alert processing module evaluates the flight path, data store, and pilot preferences and generates incursion alerts which are transmitted to each aircraft during flight, either directly or via ground based dispatchers or flight operations personnel.

Systems and methods are provided for transmitting updated weather data to an in-flight aircraft. The aircraft transmits a request for updates to a ground system that determines if the data has changed since the last transmission and transmits only the changed data. Data may be tailored to pilot preferences or to pilot requests for data representing a predetermined history.
