  • Patent number: 10079798
    Abstract: A method, system, and computer program product for enabling communication between different overlay solutions. The method includes one or more processor obtaining an address resolution request from a first resource in a first domain for a second resource in a second domain. Both domains are in a shared computing environment and the second domain includes a control plane engine. The one or more processor obtains source information from the request, registers the information to the engine, and utilizes the request to query the engine to locate the second resource in the domain. The second resource matches the request. The processor receives a response from the engine identifying a first host and the first host is in the second domain and is the host of the second resource. The processor sends a notification request to the first host requesting that the first host reply to the request.

  • Publication number: 20180234259
    Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: receiving, by a Network Virtualization Edge (NVE) of a first virtual network (VN), a multicast packet from a virtual machine (VM) of the first virtual network (VN); determining, by the NVE, whether the NVE currently supports forwarding the multicast packet to a second NVE of a second virtual network (VN), the second virtual network (VN) being logically separated from the first virtual network (VN); responsively to determining that the NVE currently supports forwarding the multicast packet to a second NVE of a second virtual network (VN) forwarding, by the NVE, the multicast packet to the second NVE.

  • Publication number: 20180013588
    Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: providing a distributed virtual gateway for Network Virtualization over Layer 3 (NVO3) network. A gateway stack having three or more nodes is implemented as a distributed virtual gateway, providing Layer 2 or Layer 3 gateway services in a fail-safe manner. Nodes of the gateway stack are configured to autonomously process and forward inbound NVO3 data packets with known destination addresses without engaging a master of the gateway stack.

  • Publication number: 20180006930
    Abstract: A mechanism for multicast (M-VIM) is used to resolve address looking up problems for different types of VXLAN related overlay networks for multicast and broadcast traffics. A Multicast Overlay Ferry Proxy (MOFP) is introduced between a VXLAN domain and the CNI domain for ferrying control plane and data panel information. The M-VIM mechanism comprises three parts: a VXLAN Module; a CNI Module; and a proxy mechanism.

  • Patent number: 9813035
    Abstract: Systems and methods disclosed herein provide for enhancing the low frequency (DC) gain of an operational amplifier with multiple correlated level shifting capacitors. In an embodiment, the operational amplifier is level shifted with a first correlated level shifting capacitor in a first phase and, then, is level shifted again with at least a second correlated level shifting capacitor in at least a second, non-overlapping, consecutive phase. In an embodiment, the multiple correlated level capacitors are controlled by a switching circuit network.

  • Publication number: 20170296631
    Abstract: The present invention comprises a method to diminish and/or eliminate atherosclerotic plaques, in mammals, through direct and indirect treatment of these plaques, in situ, using suitable substances which are capable of lipid removal, primarily through hydrolysis, either by a catalytic or stoichiometric process, wherein the substance targets receptors in and/or on the cell which lead to uptake into the lysosome. Such substances used to diminish and/or eliminate atherosclerotic plaques are generally comprised of lipid hydrolyzing proteins and/or polypeptides.

  • Patent number: 9781716
    Abstract: A high priority service sending method and device in a direct mode, and a high priority service receiving method and device in a direct mode. The receiving method includes: after sending a voice frame in a voice call sending state, a user terminal receiving and detecting a priority frame in another time slot with respect to the time slot occupied by the voice call; and if the priority frame is detected, then stopping the voice call and receiving a high priority service frame in the other time slot. Using the present invention can enable an interphone in a transmitting state in a direct mode to send or receive a high priority service as well.

  • Patent number: 9279117
    Abstract: A myeloid-specific c-fms-rtTA/(TetO)7-CMV-MMP12 bitransgenic mouse model was created. Induction of MMP12 abnormally elevated frequencies and numbers of common myeloid progenitor (CMP) and granulocyte/macrophage progenitor (GMP) populations, and decreased the frequency and number of the megakaryocyte/erythrocyte progenitor (MEP) population in bone marrow. CD11b+/Gr-1+ immature cell population increased in multiple organs. An immunosuppressive function on T cell proliferation and function by CD11b+/Gr-1+ immature cells was seen in vitro and in vivo from MMP12 over-expression. MMP12 stimulated (Lin?) progenitor cells to differentiate into CD11b+/Gr-1+ immature cells showing immunosuppression on T cell proliferation and function in vitro. Regulatory T cells were increased. In the lung, concentration of interleukin (IL)-6 was increased, which activated oncogenic signal transducer and increased expression of Stat3 downstream genes in epithelial tumor progenitor cells.

  • Publication number: 20160065445
    Abstract: In an approach to routing and forwarding a data packet with a forwarding RBridge and a corresponding RBridge, a computer, in response to receiving a TRILL data packet, performs the following steps: parsing a TRILL header of the TRILL data packet, and acquiring an egress RBridge nickname of the TRILL data packet; obtaining routing information corresponding to the egress RBridge nickname, wherein the information indicates whether the forwarding RBridge is the penultimate hop RBridge on the forwarding path to which the egress RBridge nickname is corresponding; and in response to the indication in the information that the forwarding RBridge is the penultimate hop RBridge on the forwarding path to which the egress RBridge nickname is corresponding, stripping the TRILL header of the TRILL data packet off to obtain an original data packet, and forwarding the original data packet to the egress RBridge from an out port specified by the information.
