Abstract
For security reasons, a one-way Ethernet communication link is implemented to segregate edge devices for an autonomous vehicle (AV) from the AV compute system. A non-feature rich backchannel allows very limited amounts of data to be transmitted from the edge devices side to the AV compute side. It is a challenge to query information about the edge devices when the backchannel only allows enumerated type data values to be transmitted. To address this concern, the customer-facing access point includes a relay endpoint that operates as a proxy to a web server that manages the edge devices and encodes responses as enumerated type data values to be transmitted over the backchannel.
