Abstract
A data structure is transmitted from a first computer to a second computer by transmitting a plurality of messages from the first computer to the second computer. Each message contains data of a node of the structure and one or more references to child pointer locations in previously transmitted nodes. The data of each transmitted node is stored in the second computer, and the location of each node is stored in a table of addresses and the or each reference includes an index into the table of addresses. The first computer may then use indexes into the table to identify which nodes need updating, and thus avoid the need for the first computer to know how the second computer is allocating nodes in memory. The or each reference may include an index into an array of child pointers belonging to a node, may include the sequence number of the parent node of the node being transmitted and may also include the index into the parent node's children to the pointer to the node being transmitted.
