Abstract: A method for optimizing different data streams which flow through an HTTP/2 connection. The methods involve: establishing at least first and second network connections between a first network appliance and a second network appliance prior to knowing how many HTTP/2 data streams are being multiplexed over the HTTP/2 connection; determining, by the first network appliance, a QoS of each WAN link of a plurality of WAN links; receiving, by the first network appliance, a first HTTP/2 data packet communicated over the HTTP/2 connection; obtaining a first priority designator and a first data stream's identifier contained in the packet header of the first HTTP/2 data packet; and allocating the first HTTP/2 data packet of a first data stream to the first or second network connection based on the first data stream's priority and the WAN links' QoS.

Abstract: Delivery of high quality video in an adaptive bit rate (ABR) download session is achieved using obtained using lower quality communication paths. The method involves detecting that an ABR download session of a video is in a steady-state condition. If so a further determination is made as to whether there is sufficient pre-fetch time available to download an (N+1)th video segment of the video using at alternative connection path through a virtual WAN having a lower quality than a first connection path through the virtual WAN. If sufficient pre-fetch time is available, the (N+1)th video segment is prefetched using at least the second connection path instead of the first connection path.
