Abstract: In one embodiment, a device in a network maintains a plurality of network paths for a media session. The device identifies a subset of data for the media session as requiring redundancy. The device sends a packet in the identified subset of data for the media session as redundant packets via two or more of the plurality of network paths for the media session. The device sends a particular packet outside of the identified subset of data for the media session non-redundantly via one of the plurality of network paths for the media session.

Abstract: A web conferencing operator can enable participants to share multimedia content in real-time despite one or more of the participants operating from behind a middlebox via network address translation (NAT) traversal protocols and tools, such as STUN, TURN, and/or ICE. In NAT traversal, participants share a transport addresses that the participants can use to establish a joint media session. However, connectivity checks during NAT traversal can expose a media distribution device hosted by the web conferencing operator to various vulnerabilities, such as distributed denial of service (DDoS) attacks. The web conferencing operator can minimize the effects of a DDoS attack during the connectivity checks at scale and without significant performance degradation by configuring the middlebox to validate incoming requests for the connectivity checks without persistent signaling between the web conference operator and the middlebox.

Abstract: The disclosed technology addresses the need in the art for a detecting an unauthorized participant in a multiparty conferencing session. A system is configured to join a conferencing session, obtain a roster for the conferencing session via a Session Initiation Protocol (SIP) channel, and generate a roster hash value based on the roster. The system may further receive a reference hash value from a key management server and compare the reference hash value with the roster hash value. The system may determine that the roster is invalid when the reference hash value does not match the roster hash value.

Abstract: In one embodiment, a computing device determines that a vehicle has been in an accident. The computing device also receives virtual black box data having a finite time period of recorded data from sensors that were in an operating mode during the finite time period prior to the accident, as well as a stream of data from sensors that changed to an accident mode in response to the accident. The computing device may then coordinate the virtual black box data and the stream of data for distribution to accident-based services. In another embodiment, a computing device determines identities of vehicle occupants. In response to an accident at a location, the device further determines one or more emergency services responsive to the accident at the location. As such, the device may then provide access to medical records of the occupants to devices associated with the determined emergency services.

Abstract: A method of operating a wireless device includes determining to operate the wireless device in a discontinuous reception (DRX) mode of operation such that a receiver of the wireless device is expected to operate in a low-power state during a scheduled low-power period of time and the receiver is expected to operate in an active-power state during a scheduled active-power period of time. The wireless device schedules a measurement of a positioning signal using the receiver. The measurement is scheduled to occur during a scheduled measurement period of time. The scheduled measurement period of time at least partially overlaps with at least one of the scheduled low-power period of time or the scheduled active-power period of time. The wireless device operates the wireless device in the DRX mode of operation after scheduling the measurement and before a start of the scheduled measurement period of time.

Abstract: A communication session is established between at least a first endpoint and a second endpoint, either or both of which is behind at least one network device in a network that performs network address translation. Candidate path information is obtained that indicates candidate paths in the network through which the communication session can traverse, taking into account, network address translation occurring in the network. The candidate path information is analyzed against training data and data about conditions observed on one or more candidate paths for the communication session with a machine learning-based interface selection process to produce path recommendation information indicating whether one or more candidate paths should or should not be used for the communication session between the first endpoint and the second endpoint. The path recommendation information is supplied to an endpoint in the communication session.

Abstract: An example method includes establishing a communication session between a first participant and a second participant, programming, via a control plane, a stream classifier which is to process packets associated with the communication session with classification logic. The method includes receiving a first packet at the stream classifier and, when the communication session requires recording, applying the classification logic at the stream classifier to route the first packet into a chosen service function path that includes a recording service function which reports media quality data to the control plane. Based on the media quality data, the classification logic is updated to cause a migration of the communication session to a new chosen service function path.
