Publication number: 20230353424Abstract: Approaches for a virtualized Cable Modem Termination System (CMTS) for providing high speed data services to a remote physical device (RPD). The virtualized Cable Modem Termination System (CMTS) comprises a core routing engine (CRE) for performing packet switching and routing and one or more physical or virtual compute servers (CS) that each perform CMTS functions for the one or more remote physical devices (RPDs). Multiprotocol Label Switching (MPLS) Transport Stream tunnels are employed on Ethernet links between the core routing engine (CRE) and the one or more core servers (CSs).Type: ApplicationFiled: July 4, 2023Publication date: November 2, 2023Inventors: Michael W.

Patent number: 11799722Abstract: Supporting a scalable and Highly Available (HA) service platform. The service platform may be a virtual Cable Modem Termination System (vCMTS), a Passive Optical Network (PON), or a Broadband Network Gateway (BNG). A software component receives, from the service platform, an update about a particular unit of equipment, such as a cable modem (CM), Optical Network Unit (ONU)/Optical Network Terminal (ONT), or customer premises equipment (CPE). In response to receiving the update, the software component provides, to at least one edge router, route data for the particular unit of equipment. The route data informs the edge router of a next hop network address for a network address of the unit of equipment. The edge router is not and need not be provided with either (a) any Address Resolution Protocol (ARP) data for the particular unit of equipment and (b) any Neighbor Discovery (ND) data for the particular unit of equipment.Type: GrantFiled: June 20, 2022Date of Patent: October 24, 2023Assignee: Harmonic, Inc.Inventors: Amir Leventer, Daniel Ginsburg, Robert Gaydos, Nimrod Ben-Natan

Patent number: 11425110Abstract: Exchanging encrypted packet payloads between a cable headend and a Remote MACPHY device. A single device executes a cable modem termination system (CMTS) implemented in software and not hardware. The software-implemented CMTS (i.e., a virtual CMTS) instantiates a tunnel to the Remote MACPHY device. The virtual CMTS encrypts the payloads of one or more packets and transmits those packets over the tunnel to the Remote MACPHY device. In similar fashion, the Remote MACPHY device may send packets with encrypted payloads to the virtual CMTS over the tunnel. In this way, encryption is not performed on a hop by hop basis, thereby allowing the payloads of packets to remain encrypted at all times during transmit through the tunnel.Type: GrantFiled: November 2, 2020Date of Patent: August 23, 2022Assignee: Harmonic, Inc.Inventors: Amir Leventer, Daniel Ginsburg

Patent number: 11368553Abstract: Supporting a scalable and Highly Available (HA) virtual Cable Modem Termination System (vCMTS). A software component receives, from the vCMTS, an update about a particular cable modem (CM) or customer premises equipment (CPE). The update may be sent in response to the particular CM or CPE becoming online or offline. In response to receiving the update, the software component provides, to at least one edge router, route data for the particular CM or CPE. The route data informs the edge router of a next hop network address for a network address of the particular CM or CPE. The edge router is not and need not be provided with either (a) any Address Resolution Protocol (ARP) data for the particular CM or CPE and (b) any Neighbor Discovery (ND) data for the particular CM or CPE.Type: GrantFiled: March 27, 2020Date of Patent: June 21, 2022Assignee: Harmonic, Inc.Inventors: Amir Leventer, Daniel Ginsburg, Robert Gaydos, Nimrod Ben-Natan

Publication number: 20210029049Abstract: Configurable levels of latency in data flows based on application type. An application type for a data flow is identified. The application type is one of a plurality of types that include a first type associated with applications that retransmit missing data packets not received by the intended recipient and a second type associated with applications that do not retransmit missing data packets not received by the intended recipient. Data packets of a data flow are enqueued onto a particular queue of two or more queues based on their identified application type. Each of the two or more queues store data packets of a different application type to be sent across a communication channel.Type: ApplicationFiled: July 23, 2020Publication date: January 28, 2021Inventors: Lior Assouline, Alex Muller, Nimrod Ben-Natan, Amir Leventer
