Method and device for data communication in a communication network

Abstract

The present invention relates generally to communication networks and more specifically to methods and devices for data communication over a communication network. A method according to the invention comprises, at a transmitting node: obtaining a plurality of frames including first-type frames associated with an acknowledgment policy requiring acknowledgment and second-type frames associated with an acknowledgment policy requiring no acknowledgment; aggregating the frames of the obtained plurality of frames into an aggregated frame including at least one leading frame of second type and frames subsequent thereto, in an order depending on their associated acknowledgment policies; sending the aggregated frame to a receiving node; and sending an acknowledgment request frame to the receiving node to request it to acknowledge receipt of only subsequent frames of the aggregated frame. Such data communication scheme is liable to reduce bandwidth waste and head-of-line blocking and thus latency, compared to known scheme.
