Essentially it's a single board computer with two network interfaces, one on the PCIe side, one on the bracket side.
This has been done before with the likes of DSL modems that weren't actually modems but just router-on-a-card that would just have a Realtek PCI chip on the bus side, which then directly had its GMII interface hooked up to a conexant DSL modem/router package which itself then connected to the actual on-board modem.
- zelon88 5y agoSo can you add more regular NICs and then use them as router ports?
- Nextgrid 5y agoNo. The ports on this "NIC" are actually connected to the router, though they can be passed through to the host if needed. The ports on another NIC would be assigned directly to the host. While I'm sure you can theoretically redirect them to this router wit a combination of VLANs and other Linux networking magic, you will be limited by your CPU and it's unlikely you'll manage more than a few Gbps.
- oneplane 5y agoNo, but at that point you are building a router anyway, so you might as well run the router software on the host directly instead of on the SBC host inside the main host. Keep in mind that most routers are just computers too. Sometimes they are low-power computers with special hardware components to offload specific tasks so you can trade power for specialisation (which also comes with a rigidity trade-off, you can't change the hardware after the fact like for new protocols).
