Abstract
An improved technique for processing a DHCP request from a DHCP client device is performed in a data communications device of a network (e.g., performed in a router). The technique involves receiving the DHCP request from the DHCP client device, evaluating a set of rules in response to the DHCP request to obtain a rule-based classification result, and outputting a DHCP response in response to the rule-based classification result. In some arrangements, a policy manager which is external to the data communications device plays a role in the classification process (e.g., dynamic updating of the set of rules, responding to individual queries from the data communications device when generating the rule-based classification result, etc.). Such improvements over conventional DHCP approaches enables improved flexibility and coordination of the DHCP process.
