    Abstract: A method is provided that involves obtaining service pre-conditions associated with a service to be supported in a network. The method includes providing a plurality of digital Intellectual Capital (IC) modules, and providing signature pre-condition logic that specifies one or more conditions that indicate relevancy of one or more digital IC modules. The method includes selecting, from the plurality of digital IC modules, based on the service pre-conditions and the signature pre-condition logic, one or more particular digital IC modules that are applicable to the service in the network. The method further includes determining information to be obtained from one or more nodes in the network based on the one or more particular digital IC modules, and obtaining the information from the one or more nodes in the network. The information is analyzed to determine whether the one or more specific operational issues are present in the network.

    Abstract: In one embodiment, in-band operations data (e.g., In-situ Operations, Administration, Maintenance and/or other operations data) is added to Seamless Bidirectional Forwarding (S-BFD) packets. In one embodiment, a S-BFD packet received by a node includes a BFD discriminator and operations data. Reactive processing is identified based on the BFD discriminator. The S-BFD packet and the operations data (e.g., in an operations data field in a header of the received S-BFD packet, in an IOAM Type-Length-Value (TLV), etc.) is processed according to the identified reactive function. Examples of these reactive actions include, but are not limited to, determining a result based on processing of said particular operations data by the local node or a remote analytics server, and sending a response packet including unprocessed and/or a result of the processed operations data (e.g., performance, loss, jitter, an indication of compliance with a service level agreement, and/or another data measurement or result).

    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: A system for switching from a first communication session between two endpoints to a secondary communication session when media degradation is detected is disclosed. A first endpoint is included within a first enterprise network and a second endpoint is included within a second enterprise network. The first enterprise network includes a call controller and a plurality of session border controllers (SBCs). The SBC in the first communication session detects media degradation and notifies the first endpoint of the media degradation. The first endpoint directs the call controller to establish a secondary communication session with the second endpoint when there is sufficient media degradation. The call controller directs a second SBC to establish the secondary communication session with the second endpoint. When the secondary communication session is established, the call controller directs the first endpoint to send media data using the second SBC.

    Abstract: Seamless Bidirectional Forwarding Detection (S-BFD) discriminator-based return path determination is provided. In one embodiment, a method is provided that includes assigning a first discriminator associated with a first discriminator identifier and a second discriminator associated with a second discriminator identifier different from the first discriminator. The method also includes receiving an S-BFD control packet that includes one of the first discriminator identifier or the second discriminator identifier. The method includes determining whether the first discriminator identifier or the second discriminator identifier is included in the S-BFD control packet, and based on the determination, initiating an S-BFD reflector session to transmit a response along a return path determined based on whether the first discriminator identifier or the second discriminator identifier is included in the S-BFD control packet.
