  • Patent number: 10862805
    Abstract: A network device may receive a packet associated with a traffic flow of a session that includes session identification information for the session. The network device may determine to offload subsequent packets associated with the traffic flow using offloading indicators and/or a data model. The network device may store, using a data structure, the session identification information with other session identification information for other sessions that have been selected for offloading, and may provide the packet to a device. The network device may receive another packet associated with the traffic flow, and may determine to offload the other packet by determining that the other packet includes the session identification information. The device may offload the other packet to permit the other packet to traverse through the network device without the network device performing security checks on the other packet, and may provide the other packet to the device.

  • Patent number: 10798634
    Abstract: A method and system for selecting a route in a wireless network for the transmission of a data packet between wireless nodes in the network using a modified link-state routing algorithm. A subset of nodes called portal nodes within the network are elected to do the broadcasting for the entire network. A wireless node identifies a unicast route back to its root portal node, and sends a link-state register message to this portal node. These link-state register messages received by each portal node are aggregated by them and are broadcast to each of the wireless nodes for storage. When a data packet is thereafter received by a wireless node from a neighboring node, it detects if the data packet satisfies one of a plurality of predetermined conditions and rebroadcasts the data packet to neighboring wireless nodes if none of the conditions is satisfied.

  • Patent number: 10555010
    Abstract: A system disclosed within this document is capable of improving performance in virtual computing environments, e.g., by reducing latency associated with streaming video data between a client device and an associated server system over a network. As discussed in detail below, such performance improvements can be achieved using techniques that avoid, reduce and/or overlap operations that are executed by the server system in order to render, encode, and/or transmit video data to a client device over a network. Such techniques can be used to reduce propagation and/or processing delays imposed by, for example, the server system's CPU operations, input/output (I/O), infrastructure, NIC, OS processes, among other types of hardware and software-based overheads. In various implementations, the performance enhancements can be realized at the rendering, encoding, or transmission operations performed by the server system.

  • Patent number: 10079752
    Abstract: Systems, methods, and computer-readable storage media for detecting network loops. A system can identify, for each virtual tunnel endpoint (VTEP) from multiple VTEPs in a network, respective media access control address data including the respective local interface media access control addresses of the respective VTEP and respective media access control addresses learned by the respective VTEP. The system can determine whether the VTEPs are running spanning tree protocol (STP), and whether a media access control address learned by a first VTEP matches a respective local interface media access control address of a second VTEP. The system can detect a loop when the media access control address learned by the first VTEP matches the respective local interface media access control address of the second VTEP. The system can also detect a loop when the VTEPs are running STP and the first and second VTEPs see the same STP root bridge.

  • Patent number: 10003528
    Abstract: The disclosed system handles a switch link failure in a switch fabric network. When a node in the switch fabric network detects a failure of a switch link coupled to the node, the system remaps traffic that is directed to a logical port number, which is currently mapped to a primary physical port number associated with the failed switch link, to a secondary physical port number associated with the alternative switch link. This remapping involves performing a lookup in a local mapping table at the node, wherein the local mapping table stores associations between logical port numbers and physical port numbers, wherein for each logical port number, the mapping table includes a primary physical port number and one or more secondary physical port numbers, which are associated with alternative switch links. The system notifies a subnet manager for the switch fabric network about the link failure and the remapping.
