Abstract
Network data transmission systems and methods are described. In one embodiment, a method for transmitting data between two nodes of a network can include transmitting the data using a protection bandwidth of a first transmission path between the two nodes and, based on detecting a failure condition in the first transmission path, using a different second transmission path between the two nodes to transmit the data otherwise transmitted using the protection bandwidth of the first transmission path. In one embodiment, the systems and methods can be applied to networks that use a layer-1 redundancy scheme.

A method for transmitting data between two nodes of a network, the method comprising:
- transmitting the data using a first protection bandwidth of a first transmission path between said two nodes, wherein the first transmission path comprises the first protection bandwidth and a first working bandwidth,
- detecting a failure condition in at least one of the first working bandwidth and the first protection bandwidth of the first transmission path, the failure condition including at least one of a line bit error rate and a path bit error rate that is greater than a signal degradation threshold, and
- based on detecting a failure condition in the first protection bandwidth of the first transmission path, using a second protection bandwidth of a different second transmission path between the two nodes to transmit the data previously transmitted using the first protection bandwidth of the first transmission path within a specified time period subsequent to the detected failure condition.
A processor program for transmitting data between two nodes of a network, the processor program stored on a non-transitory processor readable medium and comprising instructions to cause a processor to:
- transmit data using a first protection bandwidth of a first transmission path between the two nodes, wherein the first transmission path comprises the first protection bandwidth and a first working bandwidth,
- detect a failure condition in at least one of the first working bandwidth and the first protection bandwidth of the first transmission path, the failure condition including at least one of a line bit error rate and a path bit error rate that is greater than a signal degradation threshold, and
- based on detecting a failure condition in the first protection bandwidth of the first transmission path, use a second protection bandwidth of a different second transmission path between the two nodes to transmit the data previously transmitted using the first protection bandwidth of the first transmission path within a specified time period subsequent to the detected failure condition.
A system for transmitting data between two nodes of a network, the system comprising:
- at least two switches connected to the network and configured to:
- transmit data using a first protection bandwidth of a first transmission path between the two nodes, wherein the first transmission path comprises the first protection bandwidth and a first working bandwidth,
- detect a failure condition in at least one of the first working bandwidth and the first protection bandwidth of the first transmission path, the failure condition including at least one of a line bit error rate and a path bit error rate that is greater than a signal degradation threshold, and
- based on detecting a failure condition in the first protection bandwidth of the first transmission path, use a second protection bandwidth of a different second transmission path between the two nodes to transmit the data previously transmitted using the first protection bandwidth of the first transmission path within a specified time period subsequent to the detected failure condition.
A network comprising:
- a synchronous optical network (SONET), and at least two data switches connected to the SONET and configured to:
- transmit data using a first protection bandwidth of a first transmission path between the at least two switches, wherein the first transmission path comprises the first protection bandwidth and a first working bandwidth,
- detect a failure condition in at least one of the first working bandwidth and the first protection bandwidth of the first transmission path, the failure condition including at least one of a line bit error rate and a path bit error rate that is greater than a signal degradation threshold, and
- based on detecting a failure condition in the first protection bandwidth of the first transmission path, use a second protection bandwidth of a different second transmission path between the at least two switches to transmit the data previously transmitted using the first protection bandwidth of the first transmission path within a specified time period subsequent to the detected failure condition.
