Abstract:
1. A method for providing a fault-tolerant digital multicast all-optical network that transports and routes signals completely in an optical domain, comprising: receiving at a node having a digital operator, first data multicast from a first source to at least a first receiving node and a second receiving node; receiving at the node second data multicast from a second source to at least the first receiving node and the second receiving node; combining the first data and the second data using the digital operator at the node; sending combined first data and second data at least to the first receiving node via a link between the node and the first receiving node; buffering the second data and the combined first data and second data at the first receiving node; and recovering the first data by performing a decoding function on buffered second data and buffered combined first data and second data at the first receiving node;
