  • Patent number: 11966350
    Abstract: Embodiments herein describe a computing system which is reconfigurable into different server configurations that have different numbers of sockets. For example, the computing system may include two server nodes which can be configured into either two independent servers (i.e., two 2S servers) or a single server (i.e., one 4S server). In one embodiment, the computing system includes a midplane which is connected to processor buses on the server nodes. When configured as a single server, the midplane connects the processor bus (or buses) on one of the server nodes to the processor bus or buses on the other server node. In this manner, the processors in the two server nodes can be interconnected to function as a single server. In contrast, the connections between the server nodes in the midplane are disabled when the server nodes operate as two independent servers.

    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for monitoring application health via correctable errors. The method includes identifying, by a network device, a network packet associated with an application and detecting an error associated with the network packet. In response to detecting the error, the network device increments a counter associated with the application, determines an application score based at least in part on the counter, and telemeters the application score to a controller. The controller can generate a graphical interface based at least in part on the application score and a timestamp associated with the application score, wherein the graphical interface depicts a trend in correctable errors experienced by the application over a network.

  • Patent number: 11966413
    Abstract: In one embodiment, a first deep fusion reasoning engine (DFRE) agent in a network receives first sensor data from a first set of one or more sensors in the network. The first DFRE agent translates the first sensor data into symbolic data. The first DFRE agent applies, using a symbolic knowledge base maintained by the first DFRE agent, symbolic reasoning to the symbolic data to make an inference regarding the first sensor data. The first DFRE agent updates, based on the inference regarding the first sensor data, the knowledge base. The first DFRE agent propagates the inference to one or more other DFRE agents in the network.

  • Patent number: 11962506
    Abstract: Techniques for dynamically load balancing traffic based on predicted and actual load capacities of data nodes are described herein. The techniques may include determining a predicted capacity of a data node of a network during a period of time. The data node may be associated with a first traffic class. The techniques may also include determining an actual capacity of the data node during the period of time, as well as determining that a difference between the actual capacity and the predicted capacity is greater than a threshold difference. Based at least in part on the difference, a number of data flows sent to the data node may be either increased or decreased. Additionally, or alternatively, a data flow associated with a second traffic class may be redirected to the data node during the period of time to be handled according to the first traffic class.

  • Patent number: 11962585
    Abstract: A Third Generation Partnership Project (3GPP) based network, such as an enterprise private 3GPP network, is operative to provide a guest onboarding of a device using a realm-based discovery of an identity provider and a mutual authentication of identity federation peers. A secure connection may be established between the peers so that the device may be authenticated based on credentials associated with a Subscriber Identity Module (SIM) provided by its Mobile Network Operator (MNO). Credentials may be extended to those associated with embedded SIMs (eSIMs), digital certificates from private enterprises, login and passwords, and identities from a wide range of identity providers. After device authentication, the 3GPP-based network is operative to select and enforce access policies according to an identity or other attribute of the device.

  • Patent number: 11962473
    Abstract: Techniques for monitoring data transport in a network virtualization function chain (chain). A path tracing packet is generated having a Midpoint Compressed Data (MCD) to collect path tracing information of the chain. The network virtualization function node is configured to record an MCD containing Wide Local Path Tracing Identification (WL PT ID). The WL PT ID includes a first field having a value that indicates that a non-standard path tracing format is to be used and a second field that indicates a particular path tracing format to be used. The path tracing packet is passed through the chain and is received back after passing through the chain. Data collected by the path tracing packet is then analyzed to determine which network virtualization function nodes and chains the path tracing packet passed through and the amount of time taken for the path tracing packet to pass through the chain.

  • Patent number: 11962429
    Abstract: Techniques for virtualizing tenant transport interfaces configured to implement per-tenant network routing attribute differentiation in each tenant overlay of a multisite wide area network (WAN) and share the virtual transport interfaces between multi-tenant edge (MTE) devices providing transport services to tenant devices based on a defined tenant tier model. A Software-Defined Networking (SDN) controller may receive a physical transport interface and/or a device type associated with a tenant device. The SDN controller may determine a virtual transport interface for the tenant device based on a tier associated with the tenant. MTE device(s) may utilize the physical transport interface to establish sessions with other MTE device(s) in the WAN. The virtual transport interface may be utilized by MTE devices to implement and/or enforce network routing attributes when forwarding network traffic associated with the tenant via the sessions established between the MTE devices through the WAN.

  • Patent number: RE49926
    Abstract: A system and method for providing network and port address translation is provided. A global IP address and a block (chunk) of ports are allocated for each mobile subscriber (MS) on first data connection. Subsequent data connections from the same MS are assigned the same IP address and a new port from this block.
