Abstract:
A communication system for transmitting message packets between processing systems comprising:means in a first processing system for generating and transmitting messages in a first protocol; a parameter in said message containing a parameter identification field; an indicator encoding in said parameter identification field indicating an expanded parameter identification; an expanded parameter identification sub-field in a data field of said parameter; means in a second processing system for receiving said message; means in said second processing system for reading said parameter responsive to receiving said message; means responsive to reading said parameter for determining whether said indicator encoding is in said parameter identification field; means responsive to a determination that said indicator encoding is contained in said parameter identification field of said parameter for reading said expanded parameter identification field from said parameter containing a one of a plurality of encodings representing a parameter that is supported by said first protocol and is not supported by a second protocol; and means for processing said parameter responsive to reading said expanded encoding.
