Abstract: Boot server support in an enterprise fabric network may be provided. A border device may forward, to a configuration server, a discovery message associated with a client device and the border device may forward, to a pre-boot server, the discovery message associated with a client device. The border device may then encapsulate, in response to receiving a reply to the discovery message from the configuration server and in response to receiving a reply to the discovery message from the pre-boot server, the reply to the discovery message from the pre-boot server using a Routing Locator (RLOC) from the reply to the discovery message from the configuration server. The encapsulated reply to the discovery message from the pre-boot server may include boot information. The border device may then forward the encapsulated reply to the discovery message from the pre-boot server to an edge device associated with the client device.

Abstract: In one embodiment, a service maintains a database of media access control (MAC) addresses of devices in a network and their associated telemetry data captured from the network. The service identifies a new MAC address being used by a particular device in the network. The service matches telemetry data associated with the new MAC address with telemetry data in the database associated with another MAC address, by using the telemetry data associated with the new MAC address as input to a machine learning-based classifier. The service determines, based on the matching, that the MAC address in the database associated with the matched telemetry data has been updated to the new MAC address by the particular device.

Abstract: Techniques for extended network configuration conversion and reconfiguration are described. A network controller proceeds through a set of extended network nodes in an extended network and reconfigures ports in at the various nodes from a first configuration to a second configuration while preventing network traffic looping and maintaining data and management traffic connection to the nodes during the reconfiguration.

Abstract: In one embodiment, a device in a mesh network joins a source-destination oriented partial directed acyclic graph (SDO-PDAG) between a source node and a destination node in the network. The device receives operations, administration and maintenance (OAM) packets flooded along reverse paths of the SDO-PDAG. The device determines, based on the received OAM packets, packet drop rate (PDR) capacities of different paths between the device and the destination node. The device replicates a data packet sent from the source node to the destination node along two or more of the paths between the device and the destination node, based on the determined PDR capacities of those paths.

The debrief may be private, such that only the participant who provided the debrief may subsequently access the debrief.

Abstract: Bypassing radar in wide Dynamic Frequency Selection (DFS) channels utilizing puncturing may be provided. A first client device may be classified as eligible for puncturing and a second client device may be classified as not eligible for puncturing. Next, it may be determined that a subchannel in a bandwidth range should not be used. Then, in response to determining that the subchannel in the bandwidth range should not be used, the first client device may be steered to a first subset of the bandwidth range and the second client device may be steered to a second subset of the bandwidth range. The second subset of the bandwidth range may be smaller than the first subset of the bandwidth range.

Abstract: In one embodiment, a software agent profiler process attaches to an application and a primary instrumentation interface for the application, and discovers one or more software agents associated with the application. The software agent profiler process may then launch the one or more software agents within an encapsulated container environment of the software agent profiler process by configuring each of the one or more software agents, respectively, to point to a proxy instrumentation interface of the software agent profiler process instead of the primary instrumentation interface for the application. As such, the software agent profiler process may receive calls from the one or more software agents on the proxy instrumentation interface of the software agent profiler process, and can manage the calls from the one or more application agents prior to the calls being passed to the primary instrumentation interface for the application.

Abstract: This technology enables directed broadcasts in network fabrics. To enable a directed broadcast, a control plane node is configured to resolve directed broadcast addresses by mapping the directed broadcast address to a subnet address associated with the network fabric. A fabric border node receives a directed broadcast, extracts a destination address associated with the directed broadcast, and transmits a request to the control plane node to resolve the destination address. The control plane node retrieves the stored mapping and generates a map reply to the fabric border node with a multicast destination comprising the network fabric subnet address. The fabric border node encapsulates the directed broadcast with a header comprising the multicast destination and forwards the encapsulated directed broadcast to fabric edge nodes, which decapsulate the directed broadcast and deliver a data set from the directed broadcast to appropriate end point devices.

Abstract: In one embodiment, a supervisory service for one or more networks receives telemetry data samples from a plurality of networking devices in the one or more networks. The service trains a failure prediction model to predict failures in the one or more networks, using a training dataset comprising the received telemetry data samples. The service assesses performance of the failure prediction model. The service trains, based on the assessed performance of the failure prediction model, a machine learning-based classification model to determine whether a networking device should send a particular telemetry data sample to the service. The service sends the machine learning-based classifier to one or more of the plurality of networking devices, to control which telemetry data samples the one or more networking devices send to the supervisory service.

Abstract: Presented herein is an exemplified system and method that facilitate network-aware orchestration of similar sets of virtualized multicast-traffic receivers and/or sources (e.g., Virtual Machines) under a common network fabric element (e.g., same leaf switch and/or spine switch in a data center network fabric), e.g., to reduce network switch work load and/or number of network fabric elements involved with transmission of multicast traffic. The orchestration of scattered- and like-sets of multicast-traffic receivers and/or sources under a common network fabric element (e.g., a single and same leaf switch and/or spine switch) facilitates improvements of the operation of orchestration management technologies and virtualization overlay technologies by, e.g., improving network efficiency for multicast packet switching, reducing control plane traffic (e.g., IGMP queries), and reducing delay- and packet-transfer errors.

Abstract: In one embodiment, a monitoring process detects one or more events capable of causing a future state change in a browser application having initially loaded a single page application (SPA) page, and maintains one or more causality chains of the one or more events, each causality chain tracing events of that causality chain to a respective root cause event of that causality chain. Upon detecting a virtual page transition to create a new virtual page, the monitoring process may determine that a cause of the virtual page transition matches a particular root cause event of a particular causality chain, and correlates all events of the particular causality chain to the new virtual page (e.g., where events may notably include XHRs). In another embodiment, the monitoring process may further set a start time of the particular root cause event as the start time of the new virtual page.

Abstract: Embodiments herein describe mirroring slices in a 5G domain (or network) in a Wi-Fi domain (or network). A slice in a 5G domain allows a service provider to establish a separate network within the 5G network which can have a different minimum bandwidth, minimum latency, a quality of service (QoS) level, a certain application must be proximate to the client devices, and a service level agreement (SLA) relative to the other slices. The embodiments herein can mirror the traffic isolation and flexibility of 5G slices in a Wi-Fi network by using resource units (RUs). The AP can assign RUs in a manner to match the bandwidth and latency of the corresponding 5G slice. Further, the AP controls which client devices can use the RUs and can ensure that only the client devices that can use the same 5G slice can use the same RUs.
