Abstract
In a configuration wherein N individual fibers interconnect two devices, each fiber can be configured, through configuration of the packet processing devices at each end of the fiber, to carry traffic in a single direction. From the perspective of the first device, an arbitrary subset T of the N fibers can be used for transmitting signals to the second device. The packet processing devices terminating a subset R of the remaining N-T fibers can be configured so that the first device may receive signals from the second device.
Claims19
A method of operating a control system for an interconnection between a first device and a second device, the interconnection formed using a plurality of fibers, the method comprising:
- selecting a first fiber among the plurality of fibers, the first fiber for carrying transmission from the first device to the second device;
- and
- transmitting, to the first device, instructions directing configuration of a packet processing device connected, at the first device, to the first fiber, to select a mode that connects a first device transmit module to the first fiber.
A control system for an interconnection between a first device and a second device, the interconnection formed using a plurality of fibers, the control system configured to:
- select a first fiber among the plurality of fibers, the first fiber for carrying transmission from the first device to the second device;
- transmit, to the first device, instructions directing configuration of a packet processing device connected, at the first device, to the first fiber, to select a mode that connects a first device transmit module to the first fiber.
A device comprising:
- a transmitter module;
- a receiver module;
- a packet processing device connected to a fiber and configured to, in a first mode, connect the fiber to the transmitter module and in a second mode, connect the fiber to the receiver module;
- and
- a control system configured to control the packet processing device to select between the first mode and the second mode.
