Patent number: 11483102Abstract: A review and retry mechanism ensures a port channel can be configured to provide and maintain a minimum data speed. A timer-based review sequence reviews the constituent interfaces of a port channel to determine if a minimum speed requirement is met.

A timer-based retry sequence attempts to program the constituent interfaces. The minimum speed requirement of the interfaces is checked in the next review cycle. If the minimum speed requirement is met, then the review and retry mechanism halts and the port channel continues to remain active; otherwise, the interfaces are un-programmed and the process repeats.Type: GrantFiled: June 8, 2021Date of Patent: October 25, 2022Assignee: ARISTA NETWORKS, INC.Inventors: Utkarsha Verma, Victor Wen, Vamsi Anne

Patent number: 9980120Abstract: A method and a user equipment (UE) are provided for steering traffic within a visitor public land mobile network (VPLMN) in a wireless communication system. The UE transmits to a network, access network discovery and selection function (ANDSF)-related information comprising information on at least one of a home ANDSF (H-ANDSF) configured by a home public land mobile network (HPLMN) or a visitor ANDSF (V-ANDSF) configured by the VPLMN. The UE receives, from the network, traffic steering information which is generated by the network based on the ANDSF-related information, and steers traffic based on the received traffic steering information. The ANDSF-related information indicates whether the H-ANDSF or the V-ANDSF is an enhanced ANDSF. When the ANDSF-related information indicates that the H-ANDSF or the V-ANDSF is the enhanced ANDSF, the traffic steering information comprises a radio access network (RAN) rule parameter corresponding to a RAN rule configured by the network.Type: GrantFiled: August 7, 2014Date of Patent: May 22, 2018Assignee: LG ELECTRONICS INC.Inventors: Jaewook Lee, Sunghoon Jung, Youngdae Lee

Patent number: 9844063Abstract: A method, system, and medium are provided for dynamically enabling and disabling cyclic prefix within a long-term evolution (LTE) channel. A base station receives channel quality indication (CQI) reports indicating levels of ISI within the LTE channel. The base station determines whether the levels of ISI within the LTE channel are greater than, equal to, or less than a predetermined threshold level of ISI for the LTE channel. Based on the determination, the base station either enables or disables cyclic prefix within the LTE channel. In addition to levels of ISI, numbers of roaming users or cell edge users utilizing the LTE channel may affect whether cyclic prefix is enabled or disabled within the LTE channel.Type: GrantFiled: March 15, 2016Date of Patent: December 12, 2017Assignee: Sprint Communications Company L.P.Inventors: Sreekar Marupaduga, Rajveen Narendran, Nicholas David Caola Kullman, Andrew Mark Wurtenberger
