1. A method for providing distributed protection switching in a communication system, comprising the steps of:
- receiving a first data stream by a first communication module having an active state and a standby state, the first communication module being in the active state;
receiving a second data stream by a second communication module, the second communication module having an active state and a standby state, the second communication module being in the standby state, the first and second data streams containing similar information;
measuring by the first communication module a characteristic of the first data stream to generate a first quality measurement;
measuring by the second communication module a characteristic of the second data stream to generate a second quality measurement;
providing by the first communication module the first quality measurement to a first data processing unit (DPU) and a second DPU;
providing by the second communication module the second quality measurement to the first DPU and the second DPU;
determining by at least one of the first DPU or the second DPU a switching decision based on the first quality measurement and the second quality measurement; and
providing by the at least one of the first DPU or the second DPU a switching signal in response to the switching decision to switch the first communication module to the standby state and switch the second communication module to the active state.

Abstract
A system and method for protecting a received data stream. Active receivers and standby receivers are provided, each adaptable to receive a data stream on a traffic channel. Plural data processing units are operatively in communication with the receivers. At least one of the plural DPUs provides a switching signal to the receivers to switch the state of the active receiver to standby and the state of the standby receiver to active as a function of a quality measurement of the received data stream via the traffic channel.

11. A system for providing distributed protection switching in a communication system, comprising:
-
a first communication module configured to receive a first data stream and to measure a characteristic of the first data stream to generate a first quality measurement, the first communication module having an active state and a standby state, the first communication module being in the active state; a second communication module configured to receive a second data stream and to measure a characteristic of the second data stream to generate a second quality measurement, the second communication module having an active state and a standby state, the second communication module being in the standby state, the first and second data streams containing similar information; a first data processing unit (DPU) configured to receive the first quality measurement from the first communication module and the second quality measurement from the second communication module, the first DPU further configured to determine a switching decision based on the first quality measurement and the second quality measurement, and to provide a switching signal in response to the switching decision to switch the first communication module to the standby state and switch the second communication module to the active state; and a second DPU configured to receive the first quality measurement from the first communication module and the second quality measurement from the second communication module. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
