Patent number: 12549402Abstract: In certain implementations, a border VTEP device sends, to a second border VTEP devices, a first PIM-SM hello message indicating the border VTEP device is a local RP in a first fabric of a VxLAN. The border VTEP device receives a second PIM-SM hello message indicating that the second border VTEP devices is a local RP in a second fabric. A first PIM-SM control message is sent to the second border VTEP device, indicating PIM-SM sources in the first fabric, including a first PIM-SM source. A second PIM-SM control message is received from the second border VTEP device indicating PIM-SM sources in the second fabric. A PIM-SM join message specifying the first PIM-SM source is received from a receiver DR for a PIM-SM receiver. A PIM-SM data stream is forwarded from a source DR to the receiver DR.Type: GrantFiled: June 26, 2024Date of Patent: February 10, 2026Assignee: Hewlett Packard Enterprise Development LPInventors: Tathagata Nandy, Thomas Samuel

Patent number: 12542734Abstract: A system for efficient multicast forwarding at a switch is provided. During operation, the switch can maintain a first tunnel with a first switch in a first overlay tunnel fabric, and a second tunnel with a second switch in a second overlay tunnel fabric. The switch can operate as the gateway for both fabrics. The system can obtain a first fabric identifier and a second fabric identifier from multicast control packets received via the first and second tunnels, respectively. A fabric identifier can uniquely identify a fabric. The system can then store, in a data structure, a first network address of the first switch and a second network address of the second switch in association with the first and second fabric identifiers, respectively. The system can determine whether to forward multicast traffic to either one of the first and second fabrics based on the first and second fabric identifiers, respectively.Type: GrantFiled: April 28, 2023Date of Patent: February 3, 2026Assignee: Hewlett Packard Enterprise Development LPInventors: Tathagata Nandy, Thomas Samuel

EFFICIENT MULTICAST TRAFFIC DISTRIBUTION IN AN OVERLAY NETWORK USING UNDERLAY MULTICAST DISTRIBUTION
Publication number: 20250219929Abstract: A network device operating as a tunnel endpoint in an overlay network is provided. During operation, the network device can receive a multicast packet destined to a first multicast group via an edge port. The edge port can be coupled to the source of the first multicast group. The network device can then map the first multicast group to a second multicast group configured in an underlying network of the overlay network by applying a mapping rule. Subsequently, the network device can encapsulate the multicast packet with a first encapsulation header with a destination address, which is a multicast address of the second multicast group. The network device can then identify a Rendezvous Point (RP) of the second multicast group and forward the encapsulated multicast packet to the RP based on the multicast address of the second multicast group.Type: ApplicationFiled: March 18, 2024Publication date: July 3, 2025Inventors: Tathagata Nandy, Chethan Chavadibagilu Radhakrishnabhat, Thomas Samuel, Subramanian Muthukumar, Somnath Bhimaram Lohar -
Patent number: 12273219Abstract: A system for efficient multicast control packet forwarding is provided. During operation, the system can maintain a first tunnel between a first switch and a second switch in an overlay tunnel fabric. The encapsulation of a packet sent via the overlay tunnel fabric is initiated and terminated within the overlay tunnel fabric. The system can maintain a second tunnel between the first switch and a third switch, which can be in an external network that excludes the first and second switches. The switch can distinguish the first and second tunnels as intra-fabric and inter-fabric tunnels, respectively. Upon receiving a multicast control packet via the first tunnel, the system can identify the second tunnel as the inter-fabric tunnel and forward the multicast control packet via the second tunnel. Here, a respective multicast control packet received from the first tunnel can be precluded from being forwarded on intra-fabric tunnels.Type: GrantFiled: November 30, 2022Date of Patent: April 8, 2025Assignee: Hewlett Packard Enterprise Development LPInventors: Tathagata Nandy, Chethan Chavadibagilu Radhakrishnabhat, Thomas Samuel, Priyam De

Publication number: 20240406102Abstract: A system for efficient traffic management is provided. During operation, the system can receive a first route update via a first tunnel coupling a first switch in a first overlay tunnel fabric of a network site. The first route update can include a first set of hierarchical identifiers associated with the first switch. Here, a respective identifier can correspond to a distinct networking hierarchy with respect to the first switch. The system can also receive a second route update via a second tunnel coupling a second switch in a second overlay tunnel fabric of the site. The second route update can include a second set of hierarchical identifiers associated with the second switch. Upon receiving a packet via a tunnel, the system can determine whether to forward the packet to the first switch and the second switch based on the first and second sets of hierarchical identifiers, respectively.Type: ApplicationFiled: May 31, 2023Publication date: December 5, 2024Inventors: Saumya Dikshit, Thomas Samuel

Patent number: 11391751Abstract: Impact or acceleration sensor, which contains a liquid droplet and is designed such that the position and/or distribution of the liquid indicates whether an impact or any other acceleration of a predetermined minimum magnitude has occurred, includes: first and second foils, a cavity disposed between the foil faces of the foils and at least one retaining structure disposed on the foil face of the first and/or second foil and functions to maintain the liquid in a predetermined first sub-volume of the cavity. The retaining structure is a region of the first and/or second foil formed as a local elevation, depression or irregularity of the foil face, which forms a passable barrier for the wetting and/or contacting of the first and/or second foil by the liquid and defines an area piece of the foil face of the first and/or second foil corresponding to the first sub-volume.Type: GrantFiled: December 20, 2016Date of Patent: July 19, 2022Assignee: Schreiner Group GmbH & Co.
