    Abstract: A computer-implemented method includes sending a first request message to a first server associated with a first access network indicative of a request for an indication of whether the first server is configured to support prioritization of tunneled traffic, receiving a first response message from the first server indicative of whether the first server is configured to support prioritization of tunneled traffic, establishing one or more first tunnels with a security service when the first response message is indicative that the first server is configured to support prioritization of tunneled traffic, sending first flow characteristics and a first tunnel identifier to the first server; and receiving the first flow characteristics for each first tunnel from the first server at a first network controller. The first network controller is configured to apply a quality of service policy within the first access network for each tunnel in accordance with the flow characteristics.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for Content Delivery Networks Interconnection (CDNI) request routing using the PCP FLOWDATA option. In one aspect, a method includes receiving a request for content, and receiving, from a PCP server, flow characteristics for providing the content, where the PCP server receives the flow characteristics for providing the content from a PCP proxy that receives the flow characteristics from the client device. The method includes transmitting first data for querying the downstream content delivery network (CDN) to determine whether the downstream CDN can provide the content and satisfy the flow characteristics. The method includes receiving a response indicating the ability of the downstream CDN to provide the content and satisfy the flow characteristics, and transmitting second data based on the response, where the client device transmits flow metadata based on the second data to the PCP proxy.

    Abstract: In one embodiment, an endpoint elicits a pattern of STUN responses to identify security devices located on a call path. The endpoint then uses address information from the identified security devices to establish an efficient media flow with a remote endpoint. The endpoint can optimize the number of network devices and network paths that process the endpoint's keepalive message. Additionally, the endpoint may request custom inactivity timeouts with each of the identified security devices for reducing bandwidth consumed by keepalive traffic.

    Abstract: In one embodiment, a device in a network captures domain name system (DNS) response data from a DNS response sent by a DNS service to a client in the network. The device captures session data for an encrypted session of the client. The device makes a determination that the encrypted session is malicious by using the captured DNS response data and the captured session data as input to a machine learning-based or rule-based classifier. The device performs a mediation action in response to the determination that the encrypted session is malicious.
