  • Patent number: 12118399
    Abstract: Provided are a method and apparatus for resource allocation and an audiovisual playback terminal. The resource allocation method is applicable to a resource allocation system in an audiovisual playback terminal. The audiovisual playback terminal includes multiple device entities. The resource allocation system includes a resource configurator and several service instances. The method includes: causing the resource configurator to respond to a path requesting request from at least one target service instance, each of the path requesting requests containing a device entity list required by the target service instance in implementation of a service function; allocating device entities according to a preset resource allocation rule according to the instance attribute and the device entity list of each target service instance to create a path for each target service instance, so that the target service instance can invoke the device entities in the corresponding path to achieve the corresponding service function.

  • Publication number: 20240250909
    Abstract: In one embodiment, a method includes determining, by a first network component, a sender shaper drop value based on the following: a maximum sequence number; a minimum sequence number; and a sender sequence counter number associated with the first network component. The method also includes determining, by the first network component, a wide area network (WAN) link drop value based on the sender sequence counter number associated with the first network component and a receiver sequence counter number associated with a second network component. The method further includes determining, by the first network component, whether to adjust a sender shaper rate based on the sender shaper drop value and the WAN link drop value.

  • Patent number: 12021746
    Abstract: According to an embodiment, a node comprises one or more processors operable to execute instructions to cause the node to perform operations that comprise receiving a packet from a first node associated with an SD-WAN domain. The packet comprises a header indicating a TLOC associated with a second node to send the packet, the second node associated with an SR domain. The operations comprise determining that the TLOC corresponds to a virtual TLOC used in the SD-WAN domain to identify the second node that is in the SR domain and, in response, determining a second node identifier used in the SR domain to identify the second node. The operations further comprise preparing the packet to be communicated via the SR domain. Preparing the packet comprises including the second node identifier in the packet. The operations further comprise sending the packet comprising the second node identifier to the second node.

  • Patent number: 11991069
    Abstract: Techniques and architecture are described grouping various sources of traffic within a network into grouping fields and assigning each combination of grouping field values an aggregate identification (ID). A first hop edge router may receive a packet and search a mapping table for a corresponding aggregate ID for the combination of grouping field values within the mapping table. If not found, the first hop edge router may assign a corresponding aggregate ID for the combination of grouping field values and store the new aggregate ID for the combination of grouping field values in the mapping table. The first hop edge router may forward the packet on through the network with the aggregate ID embedded in metadata. Routers within the network may measure and aggregate flow metrics of the packet within the network based on the aggregate ID and provide the measurements to the network controller.

  • Publication number: 20240064103
    Abstract: This disclosure describes techniques and mechanisms for intelligently sampling packet flows within a network. The techniques enable the sampling of a limited set of packet flows that show greatest amount of information about the network from the packet flows in order to provide the greatest insight on application performance, network packet, and critical events within the network. Additionally, the techniques provide configurable parameters, such that the techniques are customizable for each user's network.

  • Patent number: 11881934
    Abstract: In one embodiment, a method includes receiving, by a network orchestrator, trace parameters from a user device. The method also includes determining, by the network orchestrator, to initiate a network path trace for the application, generating, by the network orchestrator, a filter policy for the network path trace using the trace parameters, and allocating, by the network orchestrator, a trace identification to the network path trace. The method also includes initiating, by the network orchestrator, the network path trace within a network by communicating the filter policy and the trace identification to a first node of the network and receiving, by the network orchestrator, network path trace data from a plurality of nodes of the network. The method further includes generating, by the network orchestrator, a trace report for the application using the network path trace data.
