Abstract: Techniques are provided for managing network traffic and alleviating network congestion issues in video conference environments. At a video conference bridge device configured to send and receive communications to an endpoint device in a network, one or more video streams are received from the endpoint participating in a video conference. Each of the video streams is classified as a rate adaptive stream or as a non-rate adaptive stream. For video streams classified as rate adaptive streams, the video streams are assigned to a buffer queue for rate adaptive streams. For video streams classified as non-rate adaptive streams, the video streams are assigned to a buffer queue for non-rate adaptive streams.

Abstract: In one embodiment, a router receives a packet, and determines an intra-flow packet priority level of the packet. The router may then map the intra-flow packet priority level to a weighted random early detection (WRED) marking based on running statistics of intra-flow packet priority levels across received flows, and marks the packet with the mapped WRED marking. By placing the marked packet into an outgoing network queue for transmission, the router may then forward or drop the marked packet based on the network queue, accordingly.

Abstract: A process to protect secure communication sessions from a network device that may have been subjected to a malicious network attack or otherwise the source of malicious network traffic. A cellular-connected network device, such as an IoT gateway, may receive data from one or more IoT devices. The cellular-connected network device may also communicate with a datacenter via a communication tunnel. The network device may include a usage profile reference. The network device, before transmitting data received from the IoT devices, may transmit the usage profile reference to the datacenter for authentication purposes. The datacenter may use the usage profile reference to resolve a usage profile that the usage profile reference references. Using the usage profile, the datacenter may negotiate with the cellular-connected network device to restrict the types of data that is transmitted between the datacenter and the cellular-connected network device.

Abstract: An apparatus may receive a plurality of data streams for transmission over a network. The apparatus may adjust packet drop rates in proportion to differences between actual bit rates and target bit rates of the data streams. Information about the adjusted packet drop rates may be provided to rate adaptive endpoints that are generating the data streams. The rate adaptive endpoints may respond to the information by adjusting the bit rates at which the data streams are encoded. Over one or more time intervals, the bit rates are adjusted to levels that yield a transmission of the data streams that is both balanced and unbiased.
