Patent number: 9936028Abstract: The present disclosure discloses a method and a network device for client association management based on estimated session duration. Specifically, a network device determines that a client device is on an active session. The client device is associated with a first access point of a plurality of access points. The network then estimates a remaining duration of the active session to obtain an estimated remaining duration. Responsive at least to the estimated remaining duration of the active session being greater than a threshold value, the network device causes the client device to associate with a second access point different than the first access point. Responsive at least to the estimated remaining duration of the active session being less than the threshold value, the network device refrains from causing the client device to associate with the second access point.Type: GrantFiled: October 21, 2014Date of Patent: April 3, 2018Assignee: ARUBA NETWORKS, INC.Inventor: Sachin Ganu

Patent number: 9936441Abstract: Infrastructure-based client management uses synthesized beacon reports to effect client association with APs in a wireless digital network. Beacon reports are synthesized by having a plurality of APs in the network collect client reports and send those reports to a report process on the network. The report process accumulates client reports from the plurality of APs and selects one or more candidate APs to support a client. Selection may be made on reported SNR, AP loading, channel loading, AP characteristics, or a combination. The report process may produce blacklists and optionally whitelists for use by APs to use in processing client probe and connection requests.Type: GrantFiled: August 1, 2011Date of Patent: April 3, 2018Assignee: ARUBA NETWORKS, INC.Inventors: Sachin Ganu, Pradeep Iyer, Partha Narasimhan

Patent number: 9930704Abstract: Described herein are systems, devices, techniques and products for configuration of access points in access point clustering environments. For example, access points are provided that self-discover existing access point clusters present on a single layer 2 broadcast domain or virtual local area network (VLAN). The access points may join one of the existing access point clusters or establish a new access point cluster, depending on compatibility or capacity, for example. Access point clusters that are present on a single VLAN may be distinguished based on a cluster identifier in order for multiple access point clusters to operate on the VLAN without creating a conflict. One or more criteria, such as a cluster identifier, a cluster size, a cluster version, a network latency, etc., may be used by an access point in determination of which of multiple access point clusters to join. When multiple clusters are operating on the VLAN, a supercluster may be formed.Type: GrantFiled: July 24, 2015Date of Patent: March 27, 2018Assignee: ARUBA NETWORKS, INC.Inventors: Hao Lu, Yan Liu

Patent number: 9893907Abstract: To facilitate management and configuration of VLAN memberships associated with applications or network protocols, a network device receives a packet from a wireless station which is a member of a virtual local area network (VLAN). The network device determines whether the packet is associated with a predefined application or network protocol.

Patent number: 9871690Abstract: The present disclosure relates to a network device that indicates a master network controller in a virtual redundant router protocol (VRRP) peer. In example implementations, the network device determines a bake-off time and refrains from sending packets during the bake-off time to a network. Also, the network device determines whether a first packet is received from the network. If either the bake-off time expires or the first packet is received from the network, the network device determines whether a spanning tree protocol (STP) convergence has completed. If so, the network device starts a VRRP state machine. If both the STP convergence has completed and the VRRP state machine has been started, the network device transmits a broadcast message indicating that the network device acts as a master network controller in the network.Type: GrantFiled: February 5, 2016Date of Patent: January 16, 2018Assignee: ARUBA NETWORKS, INC.Inventors: Isaac Theogaraj, Harsha Nagaraja
