Abstract
A computer-implemented method of distributing traffic includes distributing, to a first distributed unit (DU), traffic via a first path, receiving, from the first DU, an indication generated by a first dry contact alarm of the first DU that a state has changed in the first DU, switching, by an optical switch, the traffic from the first path to a second path based on the indication from the first DU, and distributing, to a second DU, the traffic via the second path.
Claims16
A computer-implemented method of distributing traffic, comprising:
- distributing, to a first distributed unit (DU), traffic via a first path;
- receiving, from the first DU, an indication generated by a first dry contact alarm of the first DU that a state has changed in the first DU;
- switching, by an optical switch, the traffic from the first path to a second path based on the indication from the first DU, wherein the switched traffic does not flow to the first DU;
- and
- distributing, to a second DU, the traffic via the second path,
- wherein the method further comprises:
- in response to receiving the indication that the state has changed in the first DU, sending, from the optical switch, an alarm to the second DU indicating that the state has changed in the first DU;
- and
- transmitting, from the second DU to a server device, the alarm indicating that the state has changed in the first DU.
A system for distributing traffic, comprising:
- a first distributed unit (DU);
- a second DU;
- an optical switch;
- and
- at least one processor configured to:
- distribute, to the first DU, traffic via a first path;
- receive, from the first DU, an indication generated by a first dry contact alarm of the first DU that a state has changed in the first DU;
- switch, by the optical switch, the traffic from the first path to a second path based on the indication from the first DU, wherein the switched traffic does not flow to the first DU;
- and
- distribute, to the second DU, the traffic via the second path,
- wherein the processor is further configured to:
- in response to receiving the indication that the state has changed in the first DU, send, from the optical switch, an alarm to the second DU indicating that the state has changed in the first DU;
- and
- transmit, from the second DU to a server device, the alarm indicating that the state has changed in the first DU.
A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to:
- distribute, to a first distributed unit (DU), traffic via a first path;
- receive, from the first DU, an indication generated by a first dry contact alarm of the first DU that a state has changed in the first DU;
- switch, by an optical switch, the traffic from the first path to a second path based on the indication from the first DU, wherein the switched traffic does not flow to the first DU;
- and
- distribute, to a second DU, the traffic via the second path,
- wherein the instructions, when executed, further cause the at least one processor to,
- in response to receiving the indication that the state has changed in the first DU, sending, from the optical switch, an alarm to the second DU indicating that the state has changed in the first DU;
- and
- transmitting, from the second DU to a server device, the alarm indicating that the state has changed in the first DU.
