I'm fairly new to this so please excuse my lack of knowledge here, I've tried looking up this subject which makes me even more curious now as to whether I should change my setup. I currently have GPON with Telus and the setup goes like this:
Alcatel --> ActionTec
ActionTec --> Optik STB
ActionTec --> Gigabit Switch --> Optik PVR, AppleTV, etc.
ActionTec --> Linksys Router --> WiFi/Desktop
All this is wired via ethernet.
I was just looking into it and discovered something called multicast flooding, as far as I know the gigabit switch that I have does not support IGMP filtering, so the way I have my network setup, does it mean that all the traffic the Optik PVR is seeing is actually being sent to all my devices connected to the gigabit switch? Would it make more sense to use HPNA instead? Previously whenever I've had Optik installed it's always been HPNA, but this new place has Coax, Ethernet and Phone ports on one wall plate and the installer without asking just hooked it up via Ethernet.
I'm not sure if it really does have a big impact, but I'd rather not have useless packets being flooded to my other devices that's not asking for any packets. One thing I will add is that whenever I do have the HD PVR turned on, the activity light on the gigabit switch for the uplink and for the HD PVR port blinks like crazy (as expected), but the other ports are steady, which to me seems like they're not actually getting any packets, unless it just doesn't show multicast packets?
This is really complicated (and probably pointless to most people) but I'm just really curious what some of the experts on here have to say. Sorry if this is really pointless.
