Patent number: 10136357Abstract: In order to detect congestion on a transmission link, endpoint items of network equipment are associated with congestion-detection applications. Per class of service, one application sends to the other control messages indicating volumes of data transmitted by the concerned item of network equipment via the transmission link. On reception of the control messages, the other application obtains information on volumes of data received by the other item of network equipment. By determining a first divergence in volumes of data transmitted between two control messages and a second divergence in volumes of data received, between two control messages, this other application is able to detect a situation of congestion on the transmission link occurring for one or more classes of service, and to generate an alarm signal accordingly.Type: GrantFiled: September 14, 2016Date of Patent: November 20, 2018Assignee: Airbus Defence and Space SASInventors: Marc Cartigny, Claude Poletti, Olivier Klotz

Patent number: 10129881Abstract: Disclosed is a data transmission method. The method comprises: reserving a first channel and a second channel, where the first channel is used for transmitting data and the second channel is used for transmitting ACKs; sending data to a receiving end on the first channel that is reserved; receiving an ACK that is sent by the receiving end and corresponds to the data on the second channel that is reserved and determining whether the data needs to be cached based on information carried in the ACK; and if the information carried in the ACK indicates that the receiving end has correctly received the data, clearing the data that is cached by a sending end. Through separate transmission of the data and the ACK, an efficiency problem of the sending end in providing MAC in a wireless system in a condition of a limited cache capacity is resolved.Type: GrantFiled: March 28, 2016Date of Patent: November 13, 2018Assignee: Huawei Technologies Co., Ltd.Inventors: Xun Yang, Tianyu Wu, Yunbo Li

Patent number: 10104684Abstract: A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE receives downlink control information including resource allocation information and downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the UE. A resource block pair includes a first resource block associated with a first time slot and a second resource block associated with a second time slot adjacent to the first time slot. The first and second resource blocks are allocated to the same frequency indices. A mapping between VRB pairs and PRB pairs exists such that frequency consecutive VRB pairs are mapped to non-frequency consecutive PRB pairs and that each resource block pair is split so there is a frequency gap between the first and second parts of the resource block pair.Type: GrantFiled: August 2, 2017Date of Patent: October 16, 2018Assignee: Optis Cellular Technology, LLCInventors: Dong Youn Seo, Eun Sun Kim, Bong Hoe Kim, Joon Kui Ahn

Patent number: 10064144Abstract: Combinations of correlation results are used to achieve detection of multiple coded signals at a receiver in a wireless communications system. The code applied to signals includes a lower rate code and a higher rate code. The lower rate code is a nested or tiered code such that it comprises at least two code sequences of the higher rate code. The received coded signal is correlated with the higher rate code using a single higher rate correlator to provide a higher rate code correlation result. The higher rate code correlation results are fed to two or more lower rate code correlators that combine multiple higher rate code-correlation results, each using a different lower rate code, to provide corresponding lower rate code correlation results. The presence of at least one coded signal or mutually exclusive coded signals can be determined from the lower rate code correlation results.Type: GrantFiled: November 25, 2015Date of Patent: August 28, 2018Assignee: INTEL CORPORATIONInventor: James A.

Patent number: 9985838Abstract: The techniques described are directed to providing mass withdrawal of media access control (MAC) routes for network devices in an Ethernet virtual private network data center interconnect (EVPN DCI). MAC routes to reach the learned MAC addresses are stored in routing tables with corresponding top-of-rack Ethernet segment identifier (TOR-ESI) values that represent the Ethernet segments from where the MAC addresses were learned. A provider edge (PE) network device may configure and advertise a virtual Ethernet segment identifier (vESI) that includes a plurality of TOR-ESI values. As Ethernet segments of the data center become unavailable, the corresponding TOR-ESI values may be withdrawn from the vESI to form an updated vESI. In this way, MAC routes having a TOR-ESI value that was withdrawn from the vESI may be removed from the routing tables in each of the network devices.Type: GrantFiled: March 29, 2016Date of Patent: May 29, 2018Assignee: Juniper Networks, Inc.Inventors: Wen Lin, John E.
