Ubiquiti EdgeRouter Lite Internal Block Diagram

Because of work, I ended up having one of these routers.

Having an EdgeRouter Lite to add new features in to it seemed fun. The software that powers it is pretty well known as a fork from Vyatta Core back in the 6.3 days along with Cavium’s IP Offload module that enables it to forward packets at 1 Million per second for 64 byte packets (That’s as low as an Ethernet frame can go, by the way). It’s also well known that the SoC used in this particular model is manufactured by Cavium.

However there isn’t a block diagram out there that details how the EdgeRouter Lite’s internals are hooked into. Gleaning from public information available from Cavium’s website and looking at the circuit board, I’ve drawn a block diagram which you can look at here:

I hope this simple block diagram above gives people out there a better understanding on how things are interfaced with the SoC. Have fun!
