Data transfer

Apparatus for re-assembling information cells, each respective information cell comprising a respective part of one of a plurality of messages and cell content information indicating an identity of the one of the plurality of messages the respective part of which is carried by the respective information cell, comprising:

• a message memory for respectively storing the plurality of messages, each in one or more blocks, the one or more blocks for storing each respective message of the plurality of messages being capable of being of different lengths;
• a message data memory for storing, for each respective message, message data defining a location in the message memory, a position in the one or more blocks and a length of one of the one or more blocks that is to receive the information cells of the respective message;
• a location memory for storing, for each respective message, an indication of the location of the message data stored for the respective message in the message data memory;
• loading apparatus for receiving the information cells, and for each respective information cell, accessing the location memory to determine the location of the message data for the respective message the respective part of which is carried by the respective information cell, storing the respective information cell in the message memory at the location indicated in the message data, incrementing the message data defining the location and the position in the one or more blocks in the message data memory by an amount equal to a length of the respective part of the respective message carried by the respective information cell and comparing the incremented position with the stored length of the one block for the respective message to determine whether the end of the one block has been reached.
