Abstract

In one embodiment of a network pipe optimization method, a network element (122, 400, 1002) may obtain (1108) at least one of a push pipe utilization report and a pull pipe utilization, report from each distribution node of a content delivery network ( 102, 202, 250). Based on the utilization reports, the network, element may determine (1114) new push pipe weights and new pull pipe weights for distribution pipes associated with each distribution, node of the content delivery network. Using at least one of the new push pipe weights and new pull pipe weights, a network pipe utilization model associated with the content delivery network may be simulated (1116), Responsive to determining (1118) that the simulated network pipe utilization model yields an improved utilization of the content delivery network, the new push pipe weights and new pull pipe weights may be distributed (1120) to each distribution node in the content delivery network.

Description

technical field [0001] The present disclosure generally relates to communication networks. More specifically, but not by way of limitation, the present disclosure is directed to bandwidth policy management in self-correcting content delivery networks. Background technique [0002] Content delivery networks, or CDNs (sometimes also called content distribution networks), typically use techniques such as adaptive bitrate (ABR) streaming to distribute content across nodes across the network in a "best effort" fashion. However, it is known that ABR can result in an unfair and sometimes disproportionate sharing of bandwidth on the network based on orders from multiple clients to start using network resources. Since bandwidth usage is typically determined by clients requesting content, and because ABR clients can be opportunistic, they can become greedy. For example, a client device (eg, a cell phone) with a low resolution may end up consuming a disproportionate amount of bandwid...
