Patent number: 9954608Abstract: A method and apparatus for performing path protection for rate-adaptive optics is provided. As part of the method, an aggregate input bit stream is received. The aggregate input bit stream is then transmitted using a rate-adaptive optical transceiver when transmitting on a first optical path. When the first optical path has a fault, the aggregate input bit stream is then transmitted on a second optical path using the rate-adaptive optical transceiver and a fixed-rate optical transceiver.Type: GrantFiled: August 15, 2016Date of Patent: April 24, 2018Inventors: Mark E. Boduch, Kimon Papakos

Patent number: 9954735Abstract: Before restarting an IS-IS protocol process, the first device sends an IIH packet with a RR flag set and a hold time field being a first predetermined value to a second device. The first predetermined value is greater than a normal value of a hold time kept in the second device for the first device, and the first device establishes an adjacency with the second device. After receiving an IIH packet with a RA flag replied by the second device, the first device restarts the IS-IS protocol process and starts to execute a GR process. The IIH packet with the RA flag set is replied by the second device after the second device updates the hold time kept in the second device for the first device according to the first predetermined value.Type: GrantFiled: March 11, 2014Date of Patent: April 24, 2018Assignee: HEWLETT PACKARD ENTERPRISE DEVELOPMENT LPInventor: Guobing Luo

Patent number: 9942783Abstract: Femtocell service is provided through a secondary connection to a network gateway node that is part of a service provider network. The secondary connection can be established in response to at least one telecommunication performance condition of a primary connection to the network gateway node; the at least one performance condition includes connectivity state of the primary connection or quality of traffic delivery through the primary connection. The secondary connection can be established, in part, via a home gateway node that is alternative to a home gateway node associated with a femtocell access point (AP) that enables, in part, the femtocell wireless service. The main home gateway node or the femtocell AP can initiate establishment of the secondary connection. Home gateway node(s) or femtocell AP(s) that can provide femtocell service through the secondary connection can manage connectivity with the network gateway node.Type: GrantFiled: October 13, 2016Date of Patent: April 10, 2018Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: James Fan, Jennifer K. Lam, Cheng P. Liu

Patent number: 9923781Abstract: A method is implemented by a network device functioning as a provider edge (PE) device to determine a designated forwarder (DF) for sending broadcast, unknown unicast or multicast (BUM) traffic to a customer edge (CE) device, which is connected to a plurality of PE devices in an Ethernet virtual private network (EVPN) instance on a given Ethernet segment. The method reduces a time for DF determination and loss of traffic for the CE device. The method determines whether a number of active links from the network device to the CE device is greater than an active link minimum. The method also determines that the network device is the DF in response to determining that the number of active links is greater than the active link minimum.Type: GrantFiled: November 18, 2015Date of Patent: March 20, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Prasanna Chalapathy, Antoni Przygienda

Patent number: 9917622Abstract: One embodiment is directed to a system in which an end node and a boundary link optimizer node are communicatively coupled to an ETHERNET network. The end node is communicatively coupled to the ETHERNET network using a boundary link that is connected to an edge of the ETHERNET network. A virtual local area network (VLAN) is established in the ETHERNET network that includes a first end point at the edge of the ETHERNET network and a second end point at the boundary link optimizer node. The boundary link optimizer node is configured to: receive ETHERNET packets that include data for the plurality of streams of digital samples; extract the data for the plurality of streams from the received ETHERNET packets; bundle the data for the streams of digital samples; and communicate, to the end node over the VLAN, the bundled data for the streams of digital samples in ETHERNET packets.Type: GrantFiled: March 3, 2017Date of Patent: March 13, 2018Assignee: Andrew Wireless Systems GmbHInventor: Keld Lange

Patent number: 9912580Abstract: Various embodiments of the invention provide systems, devices, and methods of configuring and controlling the operation of fallback links within a network. In certain embodiments, this is accomplished by selecting an operationally active port and internally configuring it to be part of an uplink LAG to achieve minimal L2 connectivity. Compared with existing designs, the presented invention has reduced delay time, minimal impact on network traffic, increased fallback bandwidth, faster convergence, and prevents link flaps of downstream server ports. In line with the IOA's plug- and play philosophy, no administrator intervention or reprogramming of VLANs is required in selecting fallback links.Type: GrantFiled: April 8, 2015Date of Patent: March 6, 2018Assignee: DELL PRODUCTS LPInventors: Avinash Jayakumar, Sivakami B.K., Joyas Joseph

Patent number: 9906337Abstract: A network apparatus communicates with a user equipment via multiple component carriers. The network apparatus is capable of configuring cells to correspond to the component carriers, grouping the cells into cell groups, each including cells less than or equal to a predetermined number, selecting one from the cells to be a primary cell for each cell group, and receiving a physical uplink control channel (PUCCH) on an uplink (UL) CC of the primary cell for one of the at least one CG.Type: GrantFiled: January 19, 2016Date of Patent: February 27, 2018Assignee: HTC CorporationInventors: Ling-San Meng, Chih-Hsiang Wu

Patent number: 9900231Abstract: Embodiments manage use of different network connections for data transfer in view of priority information and a data usage plan identifying threshold limits associated with the different network connections. A computing device receives data transfer requests from applications executing on the computing device. The data transfer requests have priority information associated therewith. The computing device compares the priority information with available network connections. One or more of the data transfer requests are selected for initiation based on the comparison and on the threshold limits.Type: GrantFiled: December 20, 2012Date of Patent: February 20, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Gil Zalmanovitch, Gregory James Scott, Shai Guday, Alec Garvin Kwok, Yue Jiang, Kenneth Vincent Ma
