Patent number: 8804525Abstract: A method and a device for network traffic control comprising the following steps: detecting actual downlink traffic of a network device; calculating an error e between the actual downlink traffic and predetermined downlink traffic; performing a calculation on the error to obtain PID output according to a PID control formula; calculating scaling of upstream traffic according to the calculated PID output and the downlink traffic; and regulating an upstream traffic threshold according to the scaling. The upstream traffic is increased or reduced in accordance with the actual downlink traffic be means of the correlated regulation and dynamic control of the upstream traffic and the downlink traffic of the network device. As such, traffic control is realized in those applications (e.g. UDP traffic such as P2P streaming media) which themselves lack the traffic control mechanism, and it is possible to make the best of network bandwidth as well.Type: GrantFiled: October 19, 2012Date of Patent: August 12, 2014Assignee: Sangfor Networks Company LimitedInventor: Nan Liu

Patent number: 8654726Abstract: The present invention relates to an uplink/downlink scheduling in a mobile communication system and signal transmitting/receiving scheme using the same, and more particularly a method and apparatus for a user equipment to transmit and receive signals. Each user equipment manages an interferential base station list to meet the process rate requirements. If a specific user equipment receives a first step scheduling signal including contention number information, base stations in a base station list managed by the corresponding user equipment are regarded as having real inter-cell interference links. Hence, in order for a base station having a highest priority to enable a resource assignment in a corresponding scheduling stage, a silencing signal for requesting a resource assignment prohibition is transmitted to the rest of the base stations.Type: GrantFiled: August 30, 2011Date of Patent: February 18, 2014Assignee: Seoul National University R&DB FoundationInventors: Sang Kyu Park, Sae Woong Bahk, Sung Guk Yoon

Patent number: 8606924Abstract: In a cloud computing environment customers of the cloud believe they have instantaneous access to unlimited resources however to satisfy this with finite resources there are times when resources could have to be acquired from an external cloud with potentially different security capabilities and performance capabilities. A method and system are therefore disclosed to reduce cost incurred while scaling to an external cloud to meet short term demand and to take into account security and performance requirements of customers. The proposed method and system provide automation and prediction capabilities to help with the decision of growing cloud resources or temporarily becoming a hybrid cloud. By “pre-bursting” the cloud in anticipation of a cloud burst the growth in resources can be predicted and performed (with security and load balancing in mind) prior to actual cloud consumer requests.Type: GrantFiled: March 29, 2011Date of Patent: December 10, 2013Assignee: BMC Software, Inc.Inventors: Karanbir Gujral, Suhas Kelkar
