High-quality adaptive bitrate video through multiple links
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.

Bandwidth Allocation for Low Latency Content and Buffered Content
Techniques for allocating bandwidth for low latency content and buffered content are described. In accordance with various embodiments, a bandwidth allocation method is performed at a device (e.g., a server) with one or more processors and a non-transitory memory. The server determines available bandwidth for delivering content to a client device in a stream, where the stream includes low latency content and buffered content. The server further identifies characteristics of the low latency content. The server then allocates a first portion of the available bandwidth to the low latency content and a second portion of the available bandwidth to the buffered content based on the characteristics of the low latency content.
