ABSTRACT:
Methods and apparatuses for obtaining home agent assignment. The invention uses a DNS query to signal a request for dynamic home agent assignment. The DNS query will cause a content routing device to be notified that home agent assignment is being requested. The content routing device can then use predetermined metrics to select a home agent. A DNS response will then be sent back to the device that initiated the DNS query containing the IP address of the selected home agent.
