It has a communication protocol just as do many "networks'.

Defined in Wikipedia as:

Controller-area network (CAN or CAN-bus) is a computer network protocol and bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer.

It was designed specifically for automotive applications but is now also used in other areas.

CAN is also supported in the Linux Kernel since version 2.6.25.

The connector appears to be an RJ-45 connector. Ethernet can and usually does use RJ-45 connectors. That does not define it as an Ethernet connector.

Here is a quick definition of "Ethernet" as defined by Wikipedia.

Ethernet is a family of frame-based computer networking technologies for local area networks (LANs). The name comes from the physical concept of the ether. It defines a number of wiring and signaling standards for the physical layer, through means of network access at the Media Access Control (MAC)/Data Link Layer, and a common addressing format.

Ethernet is standardized as IEEE 802.3. The combination of the twisted pair versions of Ethernet for connecting end systems to the network, along with the fiber optic versions for site backbones, is the most widespread wired LAN technology. It has been in use from around 1980[1] to the present, largely replacing competing LAN standards such as token ring, FDDI, and ARCNET.
