Abstract

Content transfer between nodes in a communications network is required in many situations. For example, between fixed nodes in a data center, between a fixed node such as a base station and a mobile node such as a mobile telephone and between mobile nodes themselves such as personal digital assistants. In an embodiment a content transfer process for use between nodes where one node knows the size of content to be transferred is described. For example, a file is divided into blocks to be sent between the nodes. A node receiving a block keeps a record of the received blocks and sends that record to the sending node at certain times. By controlling the times at which the records are sent the number of messages that need to be sent to transfer the records is low and the blocks are transferred in an efficient manner.
