Abstract

Bandwidth-efficient archiving of real-time interactive flows is disclosed herein. Related methods, systems, and computer-readable media are also disclosed. In this regard, in one embodiment, a method for archiving a real-time interactive flow is provided. The method comprises receiving, by a computing device, a real-time interactive flow, and forking the real-time interactive flow at the computing device as an archival stream. The method also comprises streaming the archival stream from the computing device to an archival repository at an adjustable streaming rate. The method additionally comprises measuring a change in a performance characteristic of the real-time interactive flow, and modifying the adjustable streaming rate based on the change in the performance characteristic of the real-time interactive flow. In this manner, a real-time interactive flow may be duplicated in a bandwidth-sensitive fashion while capturing a high-quality archive of the real-time interactive flow.
