摘要： 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.

摘要： 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.
