An autonomous driving vehicle (ADV) includes a computer network that includes at least one wireless gateway. The ADV also includes a plurality of network components coupled to the computer network, the plurality of network components including a target device. The ADV also includes a processor, configured to receive, through the at least one wireless gateway, a firmware to be installed on the target device, and to direct the firmware to the target device through a first network path of the computer network. In response to detecting a failure to update the target device with the firmware, the processor directs the firmware to the target device through a second network path of the computer network.

A video system includes a first data gathering node configured to receive a plurality of image streams from a plurality of cameras, respectively. Each of the plurality of cameras captures an environment of an autonomous driving vehicle (ADV). The first data gathering node tags the plurality of image streams with metadata that identifies each of the plurality of image streams, and combines the plurality of image streams with the metadata to form a combined image stream. A second data gathering node is communicatively coupled to the first data gathering node and is to receive the combined image stream from the first data gathering node and output the combined image stream with a second combined image stream.

In an example of the disclosed techniques, a method comprising computing, by a computing system, a distribution of symbol errors in a forward error correction (FEC) frame transmitted in an optical signal. The method further includes, in response to determining that the distribution of symbol errors indicates a burst error that satisfies a threshold, adjusting, in an optical transceiver module, one or more of a pre-cursor setting, a post-cursor setting, or a signal amplitude for the optical signal.

A distributed computing system in an autonomous driving vehicle (ADV) includes a main compute system and multiple subsystems, and a bus structure that connect the main compute system and the multiple subsystems. The bus structure provides uniform system-to-system connectivity. A host field-programmable gate array (FPGA) agent coupled to the main compute system can communicate with slave FPGA agents on the subsystems via multiple pairs of bus interface protocols of a particular type. The bus interfaces on the FPGA agents supports the uniform system-to-system connectivity.

An example cascaded optical switch includes: a fast optical switch and a slow optical switch both having input ports and output ports. A switching time of the slow switch is longer than a switching time of the fast optical switch. The cascaded optical switch includes a first pre-cabled optical fiber connecting an output port of the slow optical switch to an input ports of the fast optical switch, and a second pre-cabled optical fiber connecting an output ports of the fast optical switch to an input ports of the slow optical switch. The fast optical switch or the slow optical switch is configured to receive configuration data to modify a switching configuration to configure a fiber cross-connect in the optical switch fabric that includes at least one of the first pre-cabled optical fiber or the second pre-cabled optical fiber.

Techniques are described for providing a hybrid compensation of chromatic dispersion in optical networks to reduce power consumption by coherent receivers. In some examples, a controller may receive a chromatic dispersion value of an optical signal from a coherent receiver integrated with a receiver optical network device. The controller may compare the chromatic dispersion value with a threshold. The controller may, in response to determining that the chromatic dispersion value satisfies the threshold, perform at least one of: configure a switch connected to a dispersion compensation module (DCM) with a state to provide access to the DCM to compensate the chromatic dispersion value of the optical signal, or adjust a phase response of a filter of a coherent transmitter to compensate the chromatic dispersion value of the optical signal.
