PREDICTIVE ROAMING BETWEEN SUBNETS

摘要

A network device of a subnet determines predictive roaming information for a wireless client. Predictive roaming information can identify the wireless client and a home network subnet of the wireless client. The network device provides predictive roaming information associated with a wireless client to neighboring subnets. Neighboring subnets store received predictive roaming information, and use the predictive roaming information if the wireless client roams to them.

1. A method comprising:
selecting a first home agent in a first subnet including a first wireless access point associated with a wireless client; detecting, by the first wireless access point, a second wireless access point; determining if the second wireless access point is in a second subnet different from the first subnet; if it is determined that the second wireless access point is in the second subnet:
sending home agent information to the second wireless access point, the home agent information including an address of the first home agent;sending the home agent information from the second wireless access point to a second home agent in the second subnet, the home agent able to be used to establish a tunnel network connection between the first subnet and the second subnet when the wireless client roams from the first wireless access point in the first subnet to the second wireless access point in the second subnet.
