Patent number: 11765086Abstract: Embodiments include radio transmitters, receivers and methods of operation for enhanced bandwidth utilisation. The transmitter hashes received data blocks to produce indices associated with the received data blocks. The data blocks and associated indices are stored in memory and transmitted. If the received data blocks have previously been stored, the indices are transmitted instead of the data blocks. The receiver stores the received data blocks and associated indices in memory, and outputs the received data blocks. When the receiver receives indices instead of data blocks, it accesses the memory to look up and retrieve the associated data blocks, and outputs the retrieved data blocks.Type: GrantFiled: September 16, 2019Date of Patent: September 19, 2023Assignee: FreeWave Technologies, Inc.Inventors: Timothy G.

Patent number: 11736389Abstract: Embodiments herein facilitate the modification of data traffic load balancing on information handling systems affected by a networking information handling system having the status of one or more of its uplinks changed from operable to inoperable or from inoperable to operable. In one or more embodiments, an agent operating on or in conjunction with a networking information handling system (e.g., a TOR) detects a change in one its links. The agent sends a message to information handling system(s) (e.g., hosts) that are communicatively coupled to the TOR regarding the change in status. Based upon the TOR's message, a host may adjust its traffic load balancing to compensate for the status change. Embodiments, therefore, help efficiently utilize network pathways.Type: GrantFiled: April 16, 2021Date of Patent: August 22, 2023Assignee: DELL PRODUCTS L.P.Inventors: Sudharsan Dhamal Gopalarathnam, Vinoth Kumar Arumugam
