Patent ID: 8185928

Claim:
A method, comprising: transmitting, from a media box, a first data request to a media module at a scheduled time; determining, at the media box, that the media module is inaccessible; polling, from the media box, the media module to determine accessibility of the media module; receiving, at the media box, one or more responses to the polling of the media module, wherein the one or more responses indicate accessibility of the media module; setting, at the media box, a rescheduled time for the media box to transmit a second data request to the media module, wherein setting the rescheduled time comprises: determining a ratio between recovery period and failure period based on first-offered load and spare capacity of the media module; and setting the rescheduled time during the recovery period when the media module has capacity to handle the second data request; and transmitting, from the media box, a second data request to the media module at the rescheduled time; wherein the rescheduled time is based on: T=R L +σ( R L −R 0 ), where T represents the rescheduled time, R 0 represents time of a first (originally scheduled) poll, R k represents the times of successive polls where k=1,2,3, . . . L, and L denotes the first poll after time q, q represents the inaccessible period in seconds, σ represents a proportional factor.
