  • Patent number: 11937103
    Abstract: State information of a radio-based application, used to process messages of the application, is made accessible from a first compute instance and a second compute instance at a virtualization server. The first instance is assigned to process a first portion of a workload of the application, including a message which comprises a result of a network function executed at a network function accelerator of the server. In response to determining that a condition for migrating workload from the first compute instance has been met, an additional message of the first portion is directed to the second compute instance. The second compute instance processes the additional message using the state information.

  • Patent number: 11888701
    Abstract: Disclosed are various embodiments for improving self-healing and resiliency of radio-based networks through the use of a community model. In one embodiment, a community model graph representing a radio-based network is generated. Individual nodes of the community model graph correspond to one or more network functions of the radio-based network. Individual edges of the community model graph correspond to a respective network connection between the network function(s) of the radio-based network. The individual edges are assigned a respective measure of relative importance. An adverse health event is detected that impacts a plurality of network connections between network functions in the radio-based network. Self-healing activities for the network connections are prioritized based at least in part on the respective measures of relative importance corresponding to individual network connections.

  • Publication number: 20120081518
    Abstract: The present invention discloses a method of visualizing the 3-dimensional microstructure of a thick biological tissue. This method includes: a process of immersing thick, opaque biological tissues in the optical-clearing solution, for example FocusClear (U.S. Pat. No. 6,472,216), and utilizing an optical scanning microscope and a cutter. In microscopy, the cutter removes a portion of the tissue after each round of optical scanning. Each round of optical scanning follows the principal that the depth of the removal plane is less than the depth of the boundary plane derived from the scanning This method acquires an image stack to provide the information of thick biological tissue's 3-dimensional microstructure with minimal interference by the tissue removal.
