1. A method for communicating data between transceiver modules each having a memory defining number of tables each having a size and offset address, the method comprising:
- determining a table and offset address for requested data according to a table size of an originating module;
generating system address corresponding to the table and offset address;
transmitting a read command having a command type indicating a system address size, the system address, a length of the requested data, and a contingency field storing the table size of the originating module;
receiving the read command at a receiving module;
regenerating the table and offset address from the system address and the table size stored in the contingency field;
if the table size stored in the contingency field is the same as a table size of the receiving module, transmitting data having the length of the requested data stored at an address corresponding to the table and offset address; and
if the table size stored in the contingency field is not the same as the table size of the receiving module, transmitting data having a length different from the requested length from a table of the receiving module having a table number corresponding to the regenerated table and offset address.

Abstract
Methods for managing an optical network through out-of-band communication between optical transceiver modules in a heterogeneous network fabric are disclosed. The disclosed methods include methods for performing fabric discovery, communicating error messages, detecting intrusion. Methods are also disclosed for communicating between transceivers of differing protocol versions and memory capacity.

8. An optical transceiver comprising a receive port, a transmit port, and a processor operably coupled to the receive port, the processor programmed to:
-
receive a read command from the receive port, the read command having a command type indicating a system address size, the system address, a length of the requested data, and a contingency field storing a table size of a module that originated the read command; regenerate a table and offset address from a system address and a table size stored in a contingency field of the read command; transmit data through the transmit port having the length of the requested data stored at an address corresponding to the table and offset address if the table size of the read command is the same as a table size of the optical transceiver module; and transmit through the transmit port data having a length different from the requested length from a table of the receiving module having a table number corresponding to the regenerated table and offset address if the table size of the read command is not the same as the table size of the optical transceiver. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
