Publication number: 20150223116Abstract: 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.Type: ApplicationFiled: April 14, 2015Publication date: August 6, 2015Applicant: AEROHIVE NETWORKS, INC.Inventors: Changming Liu, Yong Kang, Jianlin Zeng, Sreekanth Reddy

Publication number: 20150188836Abstract: A technique allows stations to utilize an equal share of resources (e.g., airtime or throughput). This prevents slow stations from consuming too many resources (e.g., using up too much air time). Fairness is ensured by selective dropping after a multicast packet is converted to unicast. This prevents slow stations from using more than their share of buffer resources. Multicast conversion aware back-pressure into the network layer can be used to prevent unnecessary dropping of packets after multicast to unicast (1:n) conversion by considering duplicated transmit buffers. This technique helps achieve airtime/resource fairness among stations.Type: ApplicationFiled: March 11, 2015Publication date: July 2, 2015Applicant: AEROHIVE NETWORKS, INC.Inventors: Liwu Liu, Jianlin Zeng

Patent number: 9019938Abstract: 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: July 9, 2013Date of Patent: April 28, 2015Assignee: Aerohive Networks, Inc.Inventors: Changming Liu, Yong Kang, Jianlin Zeng, Sreekanth Reddy

Publication number: 20140283073Abstract: Managing rogue devices in a network through a network backhaul. A rogue device is detected in a network and a rogue device message that includes the rogue device is sent to a plurality of switches in a backhaul of the network. The rogue device is added into a rogue monitor table. Whether the rogue device is In-Net or Out-Of-Net is determined using forwarding tables of the plurality of switches in the backhaul of the network and the rogue monitor table. Mitigation is performed using a nearest switch to the rogue device of the plurality of switches in the backhaul of the network if it is determined that the rogue device is In-Net.Type: ApplicationFiled: March 17, 2014Publication date: September 18, 2014Applicant: AEROHIVE NETWORKS, INC.Inventors: Jianlin Zeng, Mingliang Li, Peng Fan

Publication number: 20140219128Abstract: Airtime usage may be used as a factor in controlling network traffic flow to and from client devices via a wireless network interface. Received packets or other data are assigned to a quality of service profile. Additionally, a cost value for communicating the received data is determined at least in part based on an actual or estimated airtime usage for the received packet. The cost value is used to allocate wireless network airtime to data. The allocation of wireless network airtime may be varied dynamically based on operating conditions. The cost value may be based on factors including the airtime used to communicate data; whether the data is a retransmission; and wireless network overhead. The cost value of data may also be different depending on whether the data is being sent from a client device or to a client device.Type: ApplicationFiled: April 10, 2014Publication date: August 7, 2014Applicant: AEROHIVE NETWORKS, INC.Inventors: Peter Wu, Sreekanth Reddy, Jianlin Zeng, Changming Liu
