Patent number: 10181962Abstract: Wireless access points detect neighboring wireless access points in different subnets. Upon connecting with a wireless client, a wireless access point determines predictive roaming information for the wireless client. Predictive roaming information identifies the wireless client; its home network subnet; and includes connection information associated with the wireless client. The wireless access point forwards the predictive roaming information associated with a wireless client to neighboring wireless access points while the wireless client is still connected with the wireless access point. Neighboring wireless access points store received predictive roaming information. Upon connecting with a wireless client, a neighboring wireless access point determines if the wireless client matches the stored predictive roaming information.Type: GrantFiled: August 22, 2017Date of Patent: January 15, 2019Assignee: Aerohive Networks, Inc.Inventors: Changming Liu, Yong Kang, Jianlin Zeng, Sreekanth Reddy
