  • Controlling bit-rates for media streaming sessions
    Patent number: 9894397
    Abstract: In one embodiment, a method includes (a) discerning whether an average packet delay in a media streaming session is increasing or decreasing over a first defined time window, (b) discerning whether an average jitter in the media streaming session is increasing or decreasing over a second defined time window, (c) in response to (a) and (b), calculating a specific bit-rate quantity corresponding to a change in bit-rate, and (d) controlling a bit-rate of the media streaming session in accordance with the specific bit-rate quantity.

  • Wide area network optimization
    Patent number: 8868735
    Abstract: In one embodiment, a method includes receiving application traffic at a network device from one or more endpoints, measuring performance of applications at the network device, optimizing TCP (Transmission Control Protocol) applications and UDP (User Datagram Protocol) applications based on the measured performance and policy input received at the network device, queuing the application traffic at the network device such that the application traffic shares available bandwidth in accordance with the measured performance and the policy input, and transmitting the application traffic over a wide area network. An apparatus is also disclosed.
