SVCHOST.EXE on CF 2.418

Hello members
I have reinstalled an “old” firewall v. 2.4.18 as I got tired of constantly having to adjusting the newer versions.
One of the details that got me wondering periodically is in the attached image.
svchost.exe is active for a considerable time going through the ports and comunicating with the router.
Would someone be able to enlighten me on that?
Thanks
