To get down to it my downstairs shack, upstairs office and several other rooms will share a common GigE network. All well and good for running the radio remotely, but since I only have one "inside" subnet planned so far and there will be lots of high-bandwidth traffic on it, I'm wondering what a good strategy might be? If SmartSDR 1.4 uses a fixed port range for remote operation I could get away with setting QOS priority on those ports. If not, I'm thinking I might have to create VLAN's and assign priority to the one carrying the radio traffic.
Anyone have this worked out in their head yet? Worrying about traffic on a GigE network might sound strange, but its business as usual around here.
Have all of your high-bandwidth devices directly connected to the center switch and tether lower-use, upstream switches to other places in the house for things like Netflix, Xbox, AppleTV, etc. I haven't seen my 6700 consume more than 4-5MB/sec with all DAX and DAXIQ channels in use. The future compressed audio stream will likely be low bandwidth when compared to the currently uncompressed DAX streams.
PS, do not use ring, mesh, or fully connected topologies on home switches. You do not increase bandwidth by connecting switches together with multiple ports unless they are more advanced devices. You would need to do things like Ethernet Bonding or Teaming and enable STP (Spanning Tree Protocol) to increase the actual bandwidth between switches. When you connect devices together that aren't capable of doing that, you create a situation called "Spanning Tree Loop", where switches don't know the right port to take since there are many paths available of equal quality, and this will ultimately hurt the network.
I wondered if I could get someone to spill on whether SmartSDR would use a reasonably small fixed port range - if so, I could use QOS. My switches are smart enough to do VLAN's, but that implies work on my part and possible unintended consequences later.
In truth, I shouldn't be so lazy/cheap and should physically separate my work sandbox and "home use" networks. It's just convenient to have everything available from everywhere, with no configuration required.
VLAN sandboxing would not increase total bandwidth, only isolate the traffic from other computers. VLANs will isolate broadcast and multicast traffic, but again, that should be near zero in your home, even with your setup. Then you would have to use two different IP Subnets and setup a router somewhere, which seems way more of a PITA honestly.
I like talking network. I'm a CCIE and do a ton of high bandwidth network optimization at eBay. :)
It isn't practical to isolate the cluster and clients (between 2 and LOTS) to a single switch, but I get what you mean. It was probably a poor idea to bring the whole mess up here anyway; I was hoping to prod a response on the port range. I'll just spring for one more switch and it will all work.
If I knew for sure that cheap switches from RouterBoard (for example) would be relatively RFI-free and reliable I'd buy some with SFP's and do exactly that.
Anyone that stayed awake through this thread using RouterBoard switches?
A very good use for fiber is to eliminate much EMI from some switches. Cisco put a lot of common mode RF on the wiring and STP shield where NetGear doesn't. Many switches will take 2 fiber connections; one to the shack (see lightning above) and another to one of your more remote locations.
