I was scanning my local network for ports and found 5001 tcp/commplex-link. What is it?

Apparently my home router is listening on port 5001:

Nmap scan report for 192.168.1.1 (192.168.1.1)
Host is up (0.018s latency).
Not shown: 997 closed ports
PORT STATE SERVICE
80/tcp open http
5001/tcp open commplex-link
52869/tcp open unknown

I tried googleing for port number (5001) and protocol (commplex-link) but couldn't find any clarification.

Does any body know what is that protocol or if it exists as a standard? Link to documentation would be nice.

That port is likely bound by "iperf" running on your router. iperf is used to test data throughput between two devices. If you get iperf on a computer connected to your router, you can verify this by running

iperf -c 192.168.1.1

5001 is the default port used by iperf.
