Method and system for constraining server usage in a distributed network

摘要

A “velvet rope” mechanism that enables customers of a shared distributed network (such as a content delivery network) needing to control their costs to control the amount of traffic that is served via the shared network. A given server in the distributed network identifies when a customer is about to exceed a bandwidth quota as a rate (bursting) or for a given billing period (e.g., total megabytes (MB) served for a given period) and provides a means for taking a given action based on this information. Typically, the action taken would result in a reduction in traffic served so that the customer can constrain its usage of the shared network to a given budget value.
