Abstract

A communication network (200) comprises a local information processing device (235) and a remote information system (240) that operate a transport protocol and both include a processor to perform one or more of the following data processing functions to enable data to be transmitted using the transport protocol: wrap a data block in one packet or, if the data block is larger than a largest data packet the transport protocol supports, in multiple packets. If a data block was passed in more than one packet, the data block is re-assembled from its constituent packets; and duplicated data blocks are detected and deleted. Notably, both the local information processing device (235) and the remote information system (240) estimate a likely transmission time for each data packet based on a recent communication network bit rate, and forwards the estimate from one to the other.
