QoS NooB

[cliftongr]

Hello and sorry for the long post. I'm looking for some QoS/Network setup guidance here. I don't do too much networking by trade so I hope I can find help here.
I have started out with a small network but it has ballooned over time. Now I'm starting to see issues with data being transmitted around the house. I have two major questions should I be implementing sometime of QoS? And if I need to place some smaller switches at the wallplates around my house or at my homerun will the QoS be honored by those switches? Will adding more switches to segment traffic will help or hurt?

Here is a list of the types of devices on my network:
Endpoints
Windows Media Center with with 4 extenders
One PBX with 2 phones
3 IP Cameras 2 HD 1 SD
1 wse 2012 running backups and blue iris for the cams
1 hyperV server
4 IOS devices
1 wireless printer
1 wireless clock
1 Home Automation Hub
1 wifi Thermostat
1 Xbox

Network Devices
One Fios Router wifi disabled MI424WR
One Netgear Prosafe Switch GS724T
One Ubiquiti N access point
One spare netgear JGS524 unplugged

Thanks for any help

Need more information on the existing network topology and "issues" you are having. You problem could simply be overloading link capacity.

Managed switches can implement simple ingress / egress rate limits and to 802.1p tagging. If you use tags, then all switches must support them.

From time to time (more frequently lately) I get a network trouble message while watching TV on the Media Center extenders. Also moving data large video clips from my video server seems be be moving quite slowly. I recently replaced the drives and was able to get great speed during the copy so the issue does not appear to be local.

How should I express my network topology? Is there an example I can follow so I can articulate myself a little better?

A simple drawing showing what's connected to what is sufficient.

Are your trouble devices connected via Ethernet or wireless?

I don't understand this:

Copy from where to where? What is "local"?

Since you have a smart switch you can look at port traffic and also look for high amount of dropped packets.

1)Working on the simple drawing.

2)All trouble devices are hard-wire (Media Center extenders and IP phones)

3)I checked to see if the issue was the server itself data transfer seem to be fine from disk to disk so it may be with the nic or the network.

4) I should do this when the issue pops up correct?

Network file copy is always slower than disk-to-disk. Gigabit Ethernet physical link has lower bandwidth than internal SATA and network filesystem protocols add overhead that reduces file copy throughput.

What other network or server activity is going on when you get the Media Extender messages?

You can check the switch any time for lost / retransmitted packets. If you see a port with the problem, reset statistics to start a new monitor period.

See if you can see a pattern to the problem. Is it always the same media extender(s) that throws the message? Is it a certain time of day, etc.

If all devices are plugged into the same switch, you don't need a diagram. Check the switch to see if all active ports are running at Gigabit speed.

All devices are connected to the same switch.
The media extenders are throwing a network issue dialog box.
The phones are distorting voice internally extension to extension call
The server that runs media center only runs media center nothing else.
The other server runs windows server essentials and blue iris.
One other server is running pbx in a flash.

Im starting to think it my HD cameras they are hard wired and the issue started around the time I added them to the mix. They are on 24/7

A switch isolates traffic pairs if it is working correctly. So IP cam traffic does not affect media server traffic because it is going to a different server.

If you are having VoIP call problems, that could be due to IP cams. But neither VoiP nor IP cams should affect media streaming.

Check the ports for the streamers and stream server for retransmits and dropped packets.

 

[cliftongr]

I will check the switch

On the switch log I see no errors. Transmit Packet Errors 0 for every interface

Just to check, how is the stuff passing around? If none of the links are shared, for example it is all staying on the one switch, then there shouldn't be any kind of conflicts (unless the switch itself is having problems). Is any of this traffic, other than the VOIP phones, going through the internet at any time?

What about trying to throw another switch in there and keep the media center extenders and the server feeding them on just that switch to eliminate switching issues? Any chance it is a networking issue with that server? Can you test network through put on that server and see what kind of numbers you get? Or even try attaching an extender directly to the server bypassing the switch (set static IPs) and see what the result is.

This doesn't sound like a QoS issue. It sounds like either a bad switch, or an issue with end hardware (either configuration or issues with the hardware itself). Just what KIND of servers are we talking? Scratch built newer stuff? Or is this OLD gear, like P4 era?
