  • Patent number: 11038705
    Abstract: In one embodiment, an apparatus includes a processing circuit and logic integrated with and/or executable by the processing circuit. The logic is configured to cause the processing circuit to handle Internet Group Membership Protocol (IGMP) messages received from other devices in a network. Also, the logic is configured to cause the processing circuit to create a general query solicit (GQS) message configured to solicit a general query (GQ) from a multicast snooping querier coupled with the apparatus. The GQS message causes the multicast snooping querier to send out a general query (GQ) message on all ports in response to receiving the GQS message. The GQ message is configured to solicit port information and group membership information from each IGMP switch in the network. Other systems, methods, and computer program products are described in more embodiments.

  • Patent number: 10735250
    Abstract: A load balancer system having multiple load balancer machines working in parallel. At any given time, one of the load balancer machines is assigned to act as the current distributor that distributes web client communications and/or requests to the other load balancer machines in the load balancer system. However, these web client communications and/or requests are directed to a distributor module on all of the active, parallel load balancer machines in the system (for example, by the expedient of a common virtual IP address for layer 3/4 communications) in case the currently active distributor fails and one of the other active load balancer machines suddenly needs to take on the distributor role. In this way, web client communications are not lost when the current distributor machine fails.

  • Patent number: 10361971
    Abstract: An approach is provided in which an information handling system establishes a resource reservation protocol (RSVP) session corresponding to a flow between a first entity and a second entity operating within a computer environment that implements a network virtualization overlay protocol. Once the RSVP session is established, the information handling system encapsulates data packets of the flow based on the network virtualization overlay protocol and, in turn, sends the encapsulated data packet over the computer network with a quality of service (QoS) assurance level that is based on the established RSVP session.

  • Patent number: 7875276
    Abstract: A method for providing a urinary tract tissue graft composition includes providing a segment of small intestinal submucosa and isolating and culturing at least one multipotent cell type from a tissue specimen of a subject. The at least one multipotent cell type is then seeded upon a surface of the segment of small intestinal submucosa and allowed to differentiate into a unipotent cell type, thereby forming a urinary tract tissue graft. Methods for repairing a damaged urinary tract tissue of a subject are also disclosed.
