Method and system for determining sustainable throughput over wireless networks

摘要

Sustainable average data throughput rates for data transfer between a sender and a receiver are determined for a network in a steady-state condition. Delivery performance for data transferred in non-steady-state conditions is disregarded in determining sustainable average data throughput rates. The rates may be used to adapt file delivery to network conditions.

1. A method comprising:
sending at least one data pre-burst to a receiving system during a first network condition between a sending system and the receiving system, the data pre-burst including a first file segment of a file to be sent from the sending system to the receiving system, the first network condition having a data throughput rate that is below a steady-state data throughput rate for a network link coupling the receiving and sending systems; sending at least one data measurement burst to the receiving system by the sending system during a second network condition, the data measurement burst including a second file segment of the file, the second network condition having the steady-state data throughput rate, the steady-state data throughput rate being a data throughput rate that is at or near a maximum sustainable capacity; calculating the steady-state data throughput rate based on the data measurement burst sent during the second network condition without using any data measurement for the pre-burst during the first network condition; setting a data transfer characteristic based on the calculated steady-state data throughput rate for sending a third file segment of the file to the receiving system; and sending the third file segment to the receiving system at a data transmission rate that is based on a third network condition between the receiving and sending systems and the data transfer characteristic defined at the setting operation.
