Abstract

A system employs communication messages in accordance with a determined protocol and includes a source node for producing messages in accordance with the protocol. Each message comprises at least a first level message structure with a unique tag value that identifies a class of message structures to which the first level message structure belongs. The unique tag value enables identification of a grammar template procedure that allows analysis of the first level message structure. A destination node receives the first level message structure and includes circuitry for determining the unique tag value. A memory in the destination node stores at addresses indicated by unique tag values, grammar template procedures for each class of first level message structures. A processor at the destination node is responsive to a detected unique tag value to access a grammar template procedure at an address in the memory determined from a received unique tag value and to analyze the first level message structure in accordance with the accessed grammar template procedure. The system also employs a second level message structure which includes a further unique tag value and comprises an assembly of groups of first level message structures.
