Patent number: 10305785Abstract: At least one data-stream is re-routed and a network element is provided for re-routing at least one data-stream. A first part and a second part of a data-stream received at a first node and are transmitted to a second node via two different network paths, respectively. The first is transmitted from the first node to the second node via a first network path. A second network path is determined, and the difference between latencies of the first and second network paths is also determined. If the latency of the first network path is larger than the latency of the second network path, the at least one data-stream at the first node is re-routed from the first network path to the second network path provided that the time gap between data packets received by the first node exceeds said difference between latencies.Type: GrantFiled: March 31, 2015Date of Patent: May 28, 2019Assignee: Xieon Networks S.à.r.l.Inventor: Kaiyuan Huang

Patent number: 9979678Abstract: In a networked multi computer environment with redundant links, network interface cards (NICs) are commonly duplicated and teamed to provide a recovery mechanism when network components fail. Embodiments of the present inventions avoid teaming of pairs of NICs and provide a computing host with redundant network connections for the computing host through a switch that is transparent to the computing host. The computing host itself; that is, its hardware and software, is relieved of the duty of network access redundancy and returned to the simple, simplex networking operating mode. The switch replaces a potentially large number of NICs and the need for computing host network access redundancy management which leads to hardware and software cost reductions and increases the robustness and reliability of the system through redundant network access.Type: GrantFiled: January 7, 2016Date of Patent: May 22, 2018Assignee: III HOLDINGS 1, LLCInventors: Kaiyuan Huang, Michael F.

Patent number: 9813977Abstract: WI-FI/3GPP access selection techniques are used to control selection by a user terminal between cellular network cells and WI-FI cells. Cellular network cells providing overlapping coverage with WI-FI cells are correlated with the WI-FI cells. A received signal strength threshold is determined for each WI-FI cell based on an average throughput of the cellular network cells correlated with the WI-FI cell. The WI-FI user terminal admit threshold is used to control the effective coverage of the WI-FI cell. A user terminal operating within a cellular network cell is admitted to a WI-FI only if it is within the effective coverage area of the WI-FI cell as determined by the received signal strength threshold. Increasing the threshold shrinks the effective coverage area of the WI-FI cell to allow user terminal only of strong RSSI to make connection to the cell, and steers user terminal of weak RSSI away from the WI-FI cell.Type: GrantFiled: June 14, 2016Date of Patent: November 7, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Kaiyuan Huang, Gary Tam, Stephen Rayment

Patent number: 9625497Abstract: Prediction techniques are presented for predicting a current value of a performance measurement using historic performance measurement data and recent performance measurement data, which may not reflect the current conditions. A daily trend in a series of performance measurements is obtained. The daily trend comprises a set of data points at different times of day, wherein each data point represents an average value of the performance measurements at a corresponding time of day over a plurality of days. One or more recent performance measurements over a recent time interval are also obtained. A current value of the performance measurements is predicted, based on the daily trend and the recent performance measurements.Type: GrantFiled: September 30, 2013Date of Patent: April 18, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Kaiyuan Huang, Gary Tam

Publication number: 20170078190Abstract: The present invention relates to the field of re-routing packet data in a data communication network, where it is desired to maintain the original packet order at the receiver end without significantly increasing system complexity, processing latency or related costs. For this purpose, the present invention suggests a method of re-routing at least one data-stream and a network element for re-routing at least one data-stream. A first part and a second part of a data-stream received at a first node and are transmitted to a second node via two different network paths, respectively. The first part of the at least one data-stream is transmitted from the first node to the second node via a first network path. A second network path for transmitting the second part to the second node is determined, and the difference between latencies of the first and second network paths is also determined.Type: ApplicationFiled: March 31, 2015Publication date: March 16, 2017Inventor: Kaiyuan HUANG

Patent number: 9462460Abstract: An Access Point (“AP”) apparatus comprising one or more processors containing program code. The program code may be configured to: (i) cause the AP to broadcast a beacon containing a single SSID indentifying the AP; (ii) cause the AP to receive from the STA an query for network information for at least one network operator accessible through the AP; and (iii) cause the AP to send to the STA, for the at least one network operator, a network information description element, in response to the network information query. The AP providing the plural responses broadcasts only a single service set identification (“SSID”).Type: GrantFiled: November 25, 2014Date of Patent: October 4, 2016Assignee: Telefonaktiebolaget L M EricssonInventors: Kaiyuan Huang, Stephen G.
