Publication number: 20170310533Abstract: The present invention discloses a real-time and time-distributed information recommendation system, method and apparatus. Specifically, when first clients of the information recommendation system running on first terminal devices access and operate on pieces of information, influence values of the pieces of information on friend clients of the first clients are calculated, accumulated and recorded in a database based on fried intimacy and types of the operations at the times the pieces of information are accessed and operated on. As such, the influence values of the pieces of information on friend clients are updated over time and in real-time. The speed and efficiency of processes for recommending information to the friend clients, when requested, are thus improved.Type: ApplicationFiled: July 7, 2017Publication date: October 26, 2017Applicant: Tencent Technology (Shenzhen) Company LimitedInventors: Dapeng LIU, Lei XIAO -
Patent number: 9755971Abstract: In response to receiving one or more packets from an interface, an anchoring border router classifies the traffic flow and either transmits the packets based upon the routing control table as usual, or determines that the packets of the traffic flow are to be forwarded to a forwarding border router. Upon determining that the packets are to be forwarded, the packets are encapsulated with a routing encapsulation key corresponding to a routing path and are forwarded from the anchoring border router to the forwarding border router via a routing encapsulation tunnel. When a forwarding border router receives the redirected packets over the routing encapsulation tunnel, the forwarding border router removes the routing encapsulation key from the packets of the traffic flow and transmits the packets via a routing path corresponding to the routing encapsulation key.Type: GrantFiled: February 12, 2016Date of Patent: September 5, 2017Assignee: Cisco Technology, Inc.Inventors: Xiaorong Wang, Dapeng Liu, Hunan Cao, Hongbo Xia

Patent number: 9699065Abstract: A software defined network controller detects when a host has moved between network elements in a network. The controller generates a list of network elements to which the host has roamed, the list being sorted by time when the host is attached to a network element so that a most recent network element to which the host is attached is the root network element and at a head of the list. The controller updates the root network element in the list first for traffic flow associated with the host. The controller sends commands to the network elements to program a tunnel from each previous point of attachment network element in the list to the most recent root network element in the list in reverse order of the roaming path so as to route traffic for the host via a tunnel.Type: GrantFiled: August 7, 2015Date of Patent: July 4, 2017Assignee: Cisco Technology, Inc.Inventors: Gaofeng Tao, Alan Xiao-rong Wang, Yu Zhang, Dapeng Liu

Publication number: 20160065455Abstract: Techniques whereby a LAN-side border router observes all packets of an application flow from both directions so that the application recognition performed on the LAN-side border router functions properly. A border router may implement flags in a flow cache to indicate whether the border router is the LAN-side border router and/or a WAN-side border router for an application flow. As packets are received at a border router at either the LAN interface or WAN interface, the flags associated with packet's application flows are examined to determine if the border router is the LAN-side border router for the application flow. If so, then application recognition and routing control may be performed. If not, the packet may be redirected to another border router that may be the LAN-side border router or the WAN-side border router for the application flow to insure that border router observes the packet.Type: ApplicationFiled: August 29, 2014Publication date: March 3, 2016Inventors: Alan Xiao-rong Wang, Dapeng Liu, Yu Zhang, Gaofeng Tao
