Abstract

A system includes a switch and first and second servers. The switch receives first data and provides the first data to the first and second servers. The first server determines second data based on the first data and transmits the second data to the switch. The second server determines third data based on the first data in response to a faulty indication that the first server has failed to transmit the second data to the switch and transmits the third data to the switch. The switch transmits fourth data to the second server and a third server. The fourth data is either the second data or the third data. The second data is identical to the third data so as to confirm that one of the second data or the third data is transmitted to the third server when the first server has failed to transmit the second data.

iii) transmit the first copy data stream to the at least one first server, and

iv) transmit the second copy data stream to the at least one second server;

wherein the at least one relay is configured to;

i) receive a second data stream from the at least one first server, wherein the at least one first server has generated the second data stream in response to the first copy data stream;

ii) receive a third data stream from the at least one second server, wherein the at least one second server has generated the third data stream in response to;

1) the second copy data stream and

2) at least one faulty indication, identifying that the at least one first server has failed to transmit the second data stream; and

iii) transmit a fourth data stream to the at least one second optical tap, wherein the fourth data stream is either the second data stream or the third data stream based on a receipt of a switching indicator by the at least one relay;

wherein the at least one second optical tap is configured to;

i) receive the fourth data stream,

ii) split the fourth data stream into a third copy data stream and a fourth copy data stream,

iii) transmit the third copy data stream to the at least one third server, and

iv) transmit the fourth copy data stream to the at least one second server; and

wherein the second data stream is identical to the third data stream to confirm that one of the second data stream or the third data stream is transmitted to the at least one third server when the at least one first server has failed to transmit the second data stream.

2. The system of claim 1, wherein the first data stream is an optical data stream.

3. The system of claim 1, wherein the at least one first optical tap includes at least one of a planar light-wave circuit splitter, a fused biconical taper splitter, or a thin film splitter.
