Abstract
At an intermediary dynamic host configuration protocol relay device, over a network, a dynamic host configuration protocol message is obtained from one of a plurality of remote dynamic host configuration protocol relay devices in communication with the intermediary dynamic host configuration protocol relay device over the network. The intermediary dynamic host configuration protocol relay device accesses data pertaining to a plurality of dynamic host configuration protocol back-end servers logically fronted by the intermediary dynamic host configuration protocol relay device. Based on information in the dynamic host configuration protocol message and the data pertaining to the plurality of dynamic host configuration protocol back-end servers, the dynamic host configuration protocol message is routed to an appropriate one of the plurality of back-end dynamic host configuration protocol servers.
