Performance-based selection of infrastructure service providers to provide adaptive streaming video
Techniques for serving a manifest file of an adaptive streaming video include receiving a request for the manifest file from a user device. The video is encoded at different reference bitrates and each encoded reference bitrate is divided into segments to generate video segment files. The manifest file includes an ordered list of universal resource locators (URLs) that reference a set of video segment files encoded at a particular reference bitrate. A source manifest file that indicates the set of video segment files is identified based on the request. An issued manifest file that includes a first URL and a second URL is generated based on the source manifest file. The first URL references a first domain and the second URL references a second domain that is different from the first domain. The issued manifest file is transmitted to the user device as a response to the request.
1. A method of selecting infrastructure service providers to provide adaptive streaming video, comprising:
receiving, by a performance management server, data metrics corresponding to a transmission of one or more video segment files from a first infrastructure service provider to one or more recipient devices, the video segment files corresponding to a portion of a first adaptive streaming video, wherein at least a portion of the first adaptive streaming video is not provided by the first infrastructure service provider, but is provided by one or more infrastructure service providers operated separately from the first infrastructure service provider;
determining, by the performance management server, one or more performance metrics associated with the one or more infrastructure service providers operated separately from the first infrastructure service provider, based on the received data metrics corresponding to the transmission of the video segment files from the first infrastructure service provider to the one or more recipient devices;
receiving, by the performance management server, a request for data relating to a manifest file to be created for a second adaptive streaming video;
selecting, by the performance management server, one or more infrastructure service providers to provide at least a portion of the second adaptive streaming video, based on the determined performance metrics associated with the one or more infrastructure service providers operated separately from the first infrastructure service provider; and
transmitting, by the performance management server, in response to the request, data identifying the one or more infrastructure service providers selected to provide at least a portion of the second adaptive streaming video.
2.

receiving, by the performance management server, data corresponding to a second request for a second video segment file transmitted from the first recipient device to the first infrastructure service provider;
determining, by the performance management server, that the second request includes a second URL corresponding to a failover URL within the first manifest file for the first adaptive streaming video; and
determining, by the performance management server, that the second infrastructure service provider failed to provide at least a portion of the first adaptive streaming video in between the first video segment file and the second video segment file.
7. The method of claim 1 , wherein the received request is a request for a manifest file for the second adaptive streaming video, and wherein the method further comprises:
