1. A method of data transfer in a communications system, the communications system comprising a first network node arranged to provide a first type of data and a second type of data to a second network node that requires the first type of data and the second type of data, the method comprising:
receiving, by a third network node, the first type of data using a first protocol, the first protocol defining a set of data fields corresponding to the first type of data;
transmitting, by the third network node, the first type of data to the second network node according to the first protocol, wherein the third network node lacks support for transferring the second type of data, and wherein the second type of data does not correspond to any of the data fields defined by the first protocol;
receiving, by a memory that is external to the first, second, and third network nodes, the second type of data from the first network node;
receiving, by the memory from the second network node, a request for the second type of data; and
providing, by the memory to the second network node, the second type of data to the second network node, without requiring updating of the third network node to support transferring the second type of data.
