Patent number: 10193910Abstract: It is described a network attack detection method. A topology analysis on network is conducted to obtain a probing path set containing at least one probing path. A first probing path contained in the probing path set is probed by using a probing pattern to obtain a performance metric of the first probing path. It is determined whether the first probing path is subjected to network attack according to the performance metric and a control performance metric.Type: GrantFiled: December 8, 2017Date of Patent: January 29, 2019Assignees: The Hong Kong Polytechnic University, Tencent Technology (Shenzhen) Company LimitedInventors: Lei Xue, Zhiwei Liu, Xianneng Zou, Jingang Hou, Xiapu Luo, Edmond W. W. Chan, Pei Tu, Yuru Shao

Patent number: 10178204Abstract: It is described an information processing method and device. It is received a request for service data from a client device. In response to the request for service data, it is sent at least two probing packets which contain the service data to the client device on a forward path which is from a server to the client device. It is obtained timing information, which includes: a time stamp corresponding to the service data, a time stamp corresponding to the request for the service data, and time stamps corresponding to at least two backward-path packets sent by the client device on a backward path, the backward path being from the client device to the server. It is determined according to the timing information a one-way path metric.Type: GrantFiled: March 27, 2015Date of Patent: January 8, 2019Assignees: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITED, THE HONG KONG POLYTECHNIC UNIVERSITYInventors: Xiapu Luo, Jingang Hou, Zhiwei Liu, Xianneng Zou, Juhong Wang, Lei Xue, Yajuan Tang, Weigang Wu

Patent number: 8510434Abstract: Embodiments of the present invention provide a method, system and DNS server for load balancing network servers. The method includes: monitoring whether each network server is capable of providing a network service, deleting an IP address of a network server which is incapable of providing a network service from an IP list in a DNS server or setting the IP address as invalid in the IP list according to a monitoring result; receiving, by the DNS server, a request from a network user for accessing a network server, selecting an IP address from valid IP addresses in the IP list which corresponds to the request; providing, by a network server having the selected IP address, network services for the network user.Type: GrantFiled: December 15, 2010Date of Patent: August 13, 2013Assignee: Tencent Technology (Shenzhen) Company LimitedInventors: Yanzheng Wang, Xianneng Zou
