摘要： A method for securely connecting to a remote server that provides improved Internet security. In the method, a client receives a request to connect to a remote server associated with a domain name. The client, when resolving the domain name, determines whether the remote server supports at least one predetermined IP layer security protocol. The client performs a key exchange protocol with the remote server to generate at least one shared secret in response to determining that the remote server supports the at least one predetermined IP layer security protocol. The client connects to the remote server using the at least one shared secret in the IP layer security protocol.

摘要： A method operational at a gateway device is provided to facilitate attestation of client devices by an attestation recipient device. The gateway device may obtain attestation metadata from a metadata service. It may then receive a transaction request from a client device. The client device attestation information may be verified by the gateway device against the obtained attestation metadata. The gateway device may then generate a gateway device attestation information and sends the transaction request to a recipient device along with the gateway device attestation information. The gateway device attestation information serves to at least partially vouch for the client device. The gateway may then receive a confirmation for the transaction request and forwards the confirmation for the transaction request to the client device.

摘要： Methods for delivering application content signaling information may include a generating a metadata fragment for application content items of an application to be acquired by a receiver device, adding to the metadata fragment a first set of attributes indicating that rendering of a linear service or a group of linear services is performed by a media player embedded in the application, and transmitting the metadata fragment to the receiver device. The first set of attributes may include an application launch page or launch file indicator for the application, and/or an indication of required capabilities for rendering the application and associated application content items. The first set of attributes may include a start time and an end time for at least one distribution window for the application, and the at least one distribution window may be associated with information about auxiliary application content delivered during the at least one distribution window.

摘要： The disclosure is related to dynamically applying quality of service (QoS) to a call. An aspect determines a packet transmission state of a subscriber on the call, determines whether or not the QoS is allocated to the subscriber, and allocates the QoS to the subscriber based on the QoS not being allocated to the subscriber and the packet transmission state indicating that the subscriber is sending packets.

摘要： In one example, a device includes one or more processors implemented in circuitry and configured to execute a Dynamic Adaptive Streaming over HTTP (DASH) aware application (DAA) and a DASH client, and one or more user interfaces. The DAA subscribes to DASH events of a DASH event stream via a first application programming interface (API) between the DAA and a DASH client executed by the one or more processors. The DAA then receives data for one or more DASH events of the DASH event stream from the DASH client via a second API between the DAA and the DASH client, the data for the one or more DASH events specifying interactivity-related content. The DAA then presents the interactivity-related content via the one or more user interfaces. The DAA may further send usage measurements on usage of the interactivity-related content to the DASH client, for reporting to a report server device.

摘要： An example device includes one or more processors configured to execute a proxy server for a client device including a streaming client. The proxy server is configured to determine that a tuned channel for the client device has changed from a previous channel to a current channel, and, in response to the determination that the tuned channel for the client device has changed from the previous channel to the current channel, deliver media data of the current channel to the streaming client of the client device according to a WebSocket subprotocol without receiving a request from the streaming client for the media data. In this manner, the streaming client can receive media data of the current channel (following a channel change event), without having received a manifest file for the current channel and without sending a request to the proxy server for media data of the current channel.

摘要： In an embodiment, a first WebRTC proxy module on a first UE receives a multiplexed stream from a first WebRTC multimedia client application on the first UE. The first WebRTC proxy module de-multiplexes into at least first and second de-multiplexed streams. The first WebRTC proxy module sends the first de-multiplexed stream to a second WebRTC proxy module on a second UE via a first set of links with QoS, and sends a second de-multiplexed stream to the second WebRTC proxy module on a second set of links. The second WebRTC proxy module re-multiplexes the first and second de-multiplexed streams to obtain either an original or compressed version of the multiplexed stream, and then delivers the re-multiplexed stream to a second WebRTC multimedia client application on the second UE.
