Abstract: Approaches for Converged Cable Access Platform (CCAP) processing. A software-based CCAP environment is executed on one or more physical machines. The software-based CCAP environment is maintained by a plurality of functional blocks that are each implemented in software and perform a specific function supporting the software-based CCAP environment. Each of the plurality of functional blocks performs their specific function asynchronously from each other. A configuration is maintained for the software-based CCAP environment which informs each of the plurality of functional blocks discretely for one or more Data Over Cable Service Interface Specification (DOCSIS) service groups. The configuration may treat one or more Data Over Cable Service Interface Specification (DOCSIS) service groups as a logical unit with respect to their association with each functional block.

Abstract: A urine drainage system includes a drainage tube and an outer tube extending between an interim container at a distal end and a connector at a proximal end. The drainage tube is also fluidly coupled with a urine collection container. The drainage tube is disposed with a lumen of an outer tube to define a closed annular chamber between the drainage tube and the outer tube. The system further includes an air pump in fluid communication with the annular chamber, where the air pump is configured to define a positive air pressure within the annular chamber. The drainage tube is configured to collapse as a result of the positive air pressure, and during use, collapsing the drainage tube displaces pooled urine within the drainage tube proximally toward the collection container. Different magnitudes of the positive pressure collapse different portions of the drainage tube.

Abstract: Techniques for generating and utilizing overlay-based Border Gateway Protocol (BGP) Operations, Administration, and Maintenance (OAM) packets to detect issues with an underlay network. The techniques may include receiving, from a BGP peer device via a control plane path, an OAM probe indicating a forwarding path to be used for sending the traffic to a destination associated with a prefix. The techniques may also include determining, based at least in part on the OAM probe, that a next-hop device is incapable of being utilized to forward the traffic to the destination, the next-hop device determined based on an origination of the prefix. The techniques may further include performing a policy-based action based at least in part on determining that the next-hop device is incapable of being utilized to forward the traffic to the destination.

Abstract: A system and associated methods provide procedures for establishing multicast connections and forwarding multicast content from a source to a subscriber when an ingress provider edge in communication with the subscriber is connected to an egress provider edge device belonging to an EVPN instance, especially in cases where the egress provider edge device is not receiving content from the source. The system configures “backup” provider edge devices belonging to the EVPN instance to temporarily forward the multicast content to the egress provider edge device on behalf of the source, enabling the ingress provider edge device and subscriber to continue to receive the multicast content from the source while the multicast network adjusts to recognize a new egress provider edge device. Methods of establishing connections between the ingress provider edge device and the correct egress provider edge device are also provided to avoid flooding and inefficient content forwarding throughout the network.

Abstract: According to one or more embodiments of the disclosure, an example process herein may comprise: causing, responsive to a triggering event, establishment of a service tree that follows a same path as a multicast parent tree through a data communication network to one or more intended recipient devices; causing a duplication of a particular flow from the multicast parent tree to the service tree; causing a determination of a performance characteristic of the particular flow through the service tree; and causing an association of the performance characteristic with the multicast parent tree.

Abstract: Methods and apparatuses in which unstructured computer text is analyzed for generation of a structured conversation flow for a conversation service application include a server that extracts a sequence of questions from historical voice call transcripts. The server converts each of the extracted questions into a multidimensional embedding using a sentence transformer. The server clusters the multidimensional embeddings into question clusters using a similarity measure algorithm. Each of the question clusters is assigned a cluster identification label. The server generates, for each historical voice call transcript, a sequence of cluster identification labels corresponding to the sequence of questions. The server creates a conversation flow graph for each historical voice call transcript based upon the associated sequence of cluster identification labels.

Abstract: Devices and methods are provided for exchanging route type capabilities between peer network devices, for example, Border Gateway Protocol (BGP) speakers, to prevent a BGP session reset when a particular route type is not supported by one of the peer network devices. A network device, that supports a set of route types, receives an announcing message indicating a route type capability of a peer network device. The network device selects a subset of route types supported by the peer network device from the set of route types based on the route type capability of the peer network device. The network device transmits an update message that advertises the subset of route types to the peer network device. Thus, a route type supported by the network device is not included in the update message if the route type is not advertised in the announcing message by the peer network device.

Abstract: Devices, networks, systems, methods, and processes for tracking a multi-homed host device are provided herein. A communication network may include at least two network devices and a host device that is multi-homed to the at least two network devices. A network device of the at least two network devices transmits a first tracking request to the host device and receives a tracking response for the first tracking request at a network-side interface of the network device. The first tracking request includes a first data sequence. The network device transmits, based on receiving the tracking response at the network-side interface, one or more second tracking requests with varying second data sequences in an attempt to force a response from the host device at a host-side interface of the network device. Thus, the host device is tracked in an efficient manner without changing a hashing algorithm of the host device.

At least a subset of the location tags is positioned at a fixed position along the conveyor system, and at least one location tag is positioned at the at least one other asset. Each location tag includes at least one environmental sensor and a communication interface. The communication interface is configured to transmit a sensor signal to a network system and at least one information signal to a mobile receiver.

Abstract: A system and method are provided for faster convergence with multihoming using internet protocol (IP) performance measurement (PM) sessions to report, to a transmitting provider edge (PE), a state of health of a connection between a multihomed node and a receiving (PE). The state of health can be the liveness of the connection. The receiving PE locally monitors the state of health of its connection to the node, and encodes information of the state of health in a field of the PM session messages sent to the transmitting PE. For example, while the PM session messages indicate the connection is live, traffic from the transmitting PE to the node is routed through the receiving PE. Upon the PM session messages indicating the connection is no longer live, the transmitting PE instead routes traffic to the node through another receiving PE with which the node is multihomed.
