Patent number: 9967200Abstract: Methods and systems for providing IP services in an integrated fashion are provided. According to one embodiment, a flow cache is established having multiple entries each identifying one of multiple VR flows through a VR-based network device and corresponding forwarding state information. A packet is received at an input port of a line interface module of the network device and forwarded to a VRE. Flow-based packet classification is performed by the VRE. An attempt is made to retrieve an entry of the flow cache based on a result of the flow-based packet classification. On a flow cache hit, one or more appropriate packet transformations are identified for application to the packet and it is determined whether to process the packet with a VSE based on the corresponding forwarding state information. On a flow cache miss, the new VR flow is added to the flow cache by performing flow learning.Type: GrantFiled: March 15, 2016Date of Patent: May 8, 2018Assignee: Fortinet, Inc.Inventors: Zahid Hussain, Tim Millet

Patent number: 9949195Abstract: A method and system for handover of a wireless communication device (WCD) from a source base station to a target base station that is a relay base station. The source base station may engage in procedure to handover the WCD to the target base station. A determination may be made as to whether or not the target base station is a relay base station with a wireless backhaul. If the target base station is determined to be a relay base station with a wireless backhaul, then the source base station may transmit to the WCD on an air interface a message containing a particular identifier for use by the WCD in a contention-free random access request to the source base station. In the event that the handover fails, the WCD may make a contention-free random access request to the source base station to regain access through the source base station.Type: GrantFiled: December 15, 2015Date of Patent: April 17, 2018Assignee: Sprint Spectrum L.P.Inventors: Siddharth S.

Patent number: 9917799Abstract: Some embodiments provide novel methods for controllers to communicate with managed hardware forwarding elements (MHFEs) in a transactional manner. The transactional communication methods of some embodiments ensure that an MHFE receives the entirety of a control plane update that a controller supplies to it, before the MHFE starts to modify its data plane forwarding data and operations. The transactional communication methods of some embodiments provide one or more transactional boundary controls to the controllers to define complete control plane data set updates. In some embodiments, the transactional controls ensure that an MHFE receives all of a control plane update before it starts to modify its data plane forwarding data. Controllers use one transactional control in some embodiments when they define logical forwarding elements (e.g., logical switches or routers) on the MHFEs.Type: GrantFiled: December 15, 2015Date of Patent: March 13, 2018Assignee: NICIRA, INC.Inventor: Anupam Chanda
