Abstract: An in-vehicle computing apparatus comprises a mainboard, a heat dissipation component, and a target printed circuit board (PCB). A system on chip (SOC) and a connection component are disposed on the target PCB. A side of the mainboard is attached to the heat dissipation component. The target PCB is located on a side of the heat dissipation component that faces away from the mainboard, and is detachably connected to the heat dissipation component by using the connection component.

Abstract: A signal transmission method includes receiving, by a controller, a request signal sent by a first transmitter. The method includes establishing, by the controller according to the request signal, a second optical path that connects the first transmitter to the second receiver in the optical switching network (OSN). The method includes sending, by the controller, to the second receiver according to the request signal, a reset signal used to instruct the second receiver to be reset to an initial state. The method includes sending, by the controller, an acknowledgement signal to the first transmitter. The acknowledgment signal is used to instruct the first transmitter to send, by using the second optical path, an optical signal to the second receiver.

Abstract: An optical switch control method and an apparatus are disclosed, to reduce impact on access performance by time overheads of optical link switching. The method includes: receiving an optical link establishment request sent by a computation node; determining whether the first optical link that needs to be established conflicts with the existing optical link; and if the first optical link that needs to be established conflicts with the existing optical link, determining whether to allow establishment of the first optical link, and establishing the first optical link if the establishment of the first optical link is allowed; or establishing the first optical link if the first optical link that needs to be established does not conflict with the existing optical link.
