BANDWIDTH POLICY MANAGEMENT IN A SELF-CORRECTED CONTENT DELIVERY NETWORK

摘要

In one embodiment of a network pipe optimization method, a network element may obtain at least one of a push pipe utilization report and a pull pipe utilization report from each distribution node of the content delivery network. Based on the utilization reports, the network element may determine 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. Responsive to determining 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 to each distribution node in the content delivery network.

主权项

1. A method of managing pull pipe bandwidth in a content delivery network, comprising:
redirecting a request for a particular content to an edge server node that is pre-provisioned for a push policy based on a popularity distribution associated with the requested particular content; and adjusting a pull pipe portion of a regional level distribution pipe outgoing from a regional server node to the edge server node, wherein a pull pipe weight is assigned to the regional level distribution pipe upon taking into account an expected push pipe bandwidth consumption via the regional distribution pipe for the particular content such that a Quality of Service (QoS) requirement associated with delivery of the particular content to a requesting subscriber is satisfied.
