    Abstract: This disclosure describes techniques for configuring an edge router of a communication provider network, the edge router coupled to communicate with a plurality of media streaming playback devices. Based at least in part on an indication of characteristics associated with the plurality of media streaming playback devices, a first multicast join for the edge router is configured to the communication provider network such that one or more media servers delivers a first plurality of media streams to the edge router via the communication provider network. Based at least in part on an indication of a request for an additional media stream not included in the first plurality of media streams, a second multicast join for the edge router is configured to the communication provider network such that the one or more media servers delivers the additional media stream to the edge router via the communication provider network.

    Abstract: The present technology pertains to a system that authenticates the identity of a user trying to access a service. The system comprises an authentication provider configured to communicate authentication requirements to a continuous multifactor authentication device and the continuous multifactor authentication device configured to receive authentication requirements, to fuse multiple identification factors into an identification credential for a user according to the authentication requirements, and to send the authentication credential to the authentication provider. After receiving the identification credential meeting the authentication requirements, the authentication provider is configured to instruct a service provider to initiate a session.

    Abstract: A method is performed at a router configured to perform Bit Index Explicit Replication (BIER) for forwarding of multicast packets in a network. The method includes, upon receiving a multicast packet of a multicast flow, accessing flow mappings in which multicast flows are mapped to fixed accounting values corresponding to the multicast flows. The method further comprises generating a BIER header for the multicast packet by encoding a multi-segment entropy field of the BIER header with (i) a variable entropy value for equal-cost multi-path (ECMP) load balancing, and (ii) a fixed accounting value among the fixed accounting values that is mapped to the multicast flow in the flow mappings. The method also includes encapsulating the multicast packet with the BIER header to produce an encapsulated multicast packet, and forwarding the encapsulated multicast packet.

    Abstract: Systems, methods, and computer-readable media are disclosed for use of an overlay network termination endpoint as a proxy to collect telemetry data for micro-services or specific applications provided by containers in overlay data centers. In one aspect of the present disclosure, a method includes receiving, at a controller, a probe for flow statistics associated with a service path, the probe including corresponding flow identification information, extracting the corresponding flow identification information from the probe, obtaining the flow statistics from an agent based on the flow identification information, the agent being configured to manage a plurality of containers, generating a response packet including the flow statistics obtained from the agent and sending the response packet to an initiator from which the query is received.

    Abstract: Techniques for network validation are provided. A first request is received at a first manager component, from a first client. The first client and the first manager component are on a first node of a plurality of nodes, and the first request specifies a desired network service. A first network service endpoint that is capable of providing the desired network service is identified, where the first network service endpoint is on a second node of the plurality of nodes. A connection is established between a first validation agent on the first node and a second validation agent on the second node. Finally, upon determining that the connection between the first and second validation agents satisfies predefined criteria, a connection is established between the first client and the first network service endpoint.

    Abstract: A method is provided to generate a network risk heatmap. The method includes obtaining first data related to technical support and operations issues of a network that includes a plurality of network elements and second data related to updates and configurations of the network. The method involves analyzing the first data and the second to generate a device risk heatmap rule that determines a level of predictive failure risk as a function of network telemetry data indicative of real-time operations of the network. The method further includes applying the device risk heatmap rule to network telemetry data collected from the network to create a network heatmap representing a level of predictive failure risk for the plurality of network elements in the network. The method then includes instantiating a path or tunnel in the network based on the network heatmap.

    Abstract: In some aspects, a method of the technology can include steps for sending a packet along a service function chain (SFC) to an egress node, the SFC comprising a plurality of service function forwarders (SFFs), wherein each SFF is associated with at least one service function (SF), and receiving the packet at a first SFF in the SFC, wherein the first SFF is associated with a first SF. In some aspects, the first SFF can also be configured to perform operations including: reading an option flag of the packet, and determining whether to forward the packet to the first based on the option flag. Systems and machine-readable media are also provided.
