LOW-POWER STATES IN A MULTI-PROTOCOL TUNNELING ENVIRONMENT
First Claim
Patent Images
1. A method of controlling a communication bus, comprising:
- putting at least one native protocol data stream into a tunneled protocol data stream;
determining at least one power event transition in the at least one native protocol data stream; and
adjusting a bandwidth of the tunneled protocol data stream based on a bandwidth requirement of the at least one native protocol data stream as indicated by the at least one power event transition in the at least one native protocol data stream.

Abstract
A power circuit is added at a host that determines that a native protocol using a given lane within a tunneled environment has entered a low-power state and provides a throttle instruction to a router in the host. The router may then transmit on fewer lanes. The reduction in the number of lanes used reduces power consumption, thus preserving the value associated with the native protocol entering the low-power state.

13. A host router comprising:
-
a bus interface configured to place a tunneled data path on a communication cable; and a control system configured to; put at least one native protocol data stream into a tunneled protocol data stream; determine at least one power transition in the at least one native protocol data stream; and change a power state of a lane corresponding to the at least one native protocol data stream responsive to the at least one power transition. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
