Abstract:
1. A system comprising: an optical channel transport unit (OTU) framer to frame information of an optical burst including an optical burst format into an OTU frame, the OTU frame including an overhead portion, a payload portion and a error correction portion, wherein the overhead portion includes a first field to indicate whether the OTU frame was encoded with error correction coding and a second field to indicate a type of data carried in the error correction portion when the first field indicates that the OTU frame was encoded without error correction coding, wherein the second field further indicates whether the type of data carried in the error correction portion is different from a type of data carried in the payload portion when the OTU frame is encoded without error correction coding; and an optical interface to transmit the OTU frame to a node of an optical network, the node comprising an optical switch.
