Abstract: Techniques for dynamically negotiating a service legal agreement (SLA) between a roaming device and a visited network (VN) in an identity federation. An identity profile provided to a user device by an identity provider (IDP) is accessed by the user device. The identity profile includes a first SLA criteria. An advertisement from the VN indicating one or more SLAs supported by the VN is received at the user device. The advertisement is received before the user device has associated with the VN. The IDP and the VN are part of a same identity federation. It is determined that the SLA supported by the VN satisfies the first SLA criteria. Upon that determination, an acceptance is transmitted by the user device to the VN, and the user device is associated with the VN.

Abstract: A system and method for authenticating a user via a single voice audio input is disclosed. The method includes obtaining voice audio from a user, converting the voice audio to text, comparing at least a portion of the text to a database, determining whether a user profile exists in the database based on the comparing, the user profile including a voiceprint, in response to determining that the user profile exists in the database, analyzing the voice audio against the voiceprint of the user profile; and authenticating the user based on the voice audio substantially matching the voiceprint of the user profile.

Abstract: In one embodiment, a device in a network detects an encrypted traffic flow associated with a client in the network. The device captures contextual traffic data regarding the encrypted traffic flow from one or more unencrypted packets associated with the client. The device performs a classification of the encrypted traffic flow by using the contextual traffic data as input to a machine learning-based classifier. The device generates an alert based on the classification of the encrypted traffic flow.

Abstract: Systems, methods, and computer-readable media for performing threat remediation through a switch fabric of a virtualized network environment. Data traffic passing into a virtualized network environment including a plurality of virtual machines running on a switch fabric is monitored. A network threat introduced through at a least a portion of the data traffic is identified at the switch fabric. One or more remedial measures are performed in the network environment based on the identification of the network threat in the virtualized network environment.

Abstract: Method and apparatus including a wireless access point system with an environmental sensor adapted to detect an environmental parameter of an area and a wireless access point. The wireless access point includes a wireless communication module adapted to provide a wireless communication signal; a radar module adapted to provide, via the wireless communication signal, a radar with a field of view of or within the area; and an object detection module adapted to determine if one or more sentient beings are present within the field of view, the wireless access point system adapted to calibrate the environmental sensor based on the object detection module determining, for a time duration, an absence of the one or more sentient beings.

Abstract: Presented herein are techniques to support handovers in hybrid cell configuration environments. In one example, a method may include determining that a user equipment (UE) is connected to a first shared cell or a first unique cell of a radio access network; and causing a handover for the UE to a second shared cell or a second unique cell of the radio access network based on whether the UE is connected to the first shared cell or the first unique cell, wherein the handover is performed between one of the first shared cell and the second shared cell or the first unique cell and the second unique cell.

Abstract: Techniques and mechanisms for a control plane approach for dense topologies that focusses on discovering shared ECMP groups in the control plane independent of per-prefix learning and then learning prefixes via these shared ECMP groups instead of learning prefixes via one next-hop at a time. In dense topologies, this approach helps minimize BGP path scale, corresponding signaling and enables control plane scaling that is an order of magnitude higher than a traditional eBGP control plane. During link and node topology changes, the described control plane approach enables control plane signaling that is prefix independent and an order of magnitude lower. A control plane approach to path-list sharing and prefix independent signaling on link and node topology changes enables prefix independent convergence (PIC) in scenarios that would not be possible otherwise with traditional FIB driven path-list sharing and PIC.

Abstract: Secure network segmentation using logical subnet segments is described. A single network segment or subnet provided by a third party is mapped into multiple layer-3 virtual or logical segments without requiring separate subnets. This mapping is accomplished by using virtual routing functions (VRFs) per logical subnet segment while retaining a single subnet across the segments. The logical subnet segments interact with the single network segment provided by the third party (ISP). The layer-3 VRF instances are created without the need for separate IP subnet pools per layer-3 segment. Each VRF instance for the various logical subnet segments is mapped to an identifier and tag.

Abstract: Embodiments described herein improve availability of a power plane in a network device by using a PoE manager that is separate from an operating system in the network device. For example, when the operating system (or a PoE application executing in the operating system) becomes unavailable, either because of failure or system upgrade, the PoE manager continues managing a power plane in the network device such that connected PDs continue to receive DC power. Stated differently, by using a PoE manager that is separate from the operating system, there is no fate sharing between the PoE manager and the operating system. If the operating system is unavailable, the PoE manager continues to provide the same power allotment to the PDs. As such, updates and failures which previously made the power plane unavailable no longer affect the power supplied to the PDs.
