Abstract
A method for resilient file transfer comprises transmitting, by a source, a fragment of a file to a destination. The method further comprises transmitting, by the destination, an acknowledgement to the source, when the destination receives the fragment. Also, the method comprises calculating a current delay measurement (δ), which is a difference of a time the fragment is transmitted from the source and a time the acknowledgement is received by the source, when the source receives the acknowledgement. Additionally, the method comprises calculating a current delay estimation (δ), which is a sum of a previous delay estimation (δ) weighted by a variable alpha (α) and the current delay measurement (δ) weighted by a variable beta (β), when the source receives the acknowledgement. Further, the method comprises determining whether a subsequent fragment transmitted should be retransmitted by the source to the destination by using the current delay estimation (δ).
