As anyone who has played the LK tf2 server knows, there are big issues with lag that occur sporadically.

This leads me to wonder: how is the network set up? What is the maximum throughput for each switch? What is the maximum upload - to the LAN - that the server box can push? What is the maximum rate the server box can download/upload from a computer on the LAN we can assume has the best NIC?

TF2 server rates were 10-30kBps per player( * 32, gives us about 960 kBps max). There's no reason it should lag. What is our router? I see something like three switches, is the server box used as the router? I know it acts as the connection to the internet(I am not sure how unless it is the router).

Also, do the switches run an operating system, or is there any way to get them list the throughput to each client? Or, if it's a linux flavor, could they be ssh'd into and nettop/ifconfig to list bandwidth usage on each ethernet device?

There's got to be a better way to monitor it.

Also: is there any way to do port-based QoS on whatever our router is, or if it isn't the WS08 box monitor transfer based on destination port(to determine if it is just http downloading or what)

We usually do the following setup:

1) 24-slot Switch per table row
2) One 8 slot Switch
3) Lianri as our DHCP server and main LAN input

Tubes go from wall, to liandri. Liandri then is connected to the first 8-slot switch via a secondary LAN port. At that point the tubes are distributed via the 8-slot switch to the other 24-slot switches, which are then used to distribute LAN to the individual computers(cable bundles are hooked up to the 24-port switches).

As far as the lag goes or individual throughput of each switch, we'd need to check on that.

I know chris has some way of monitoring network rates/ip, but I think that's only on one of the switches, not all of them.

ah, maybe we've got one managed switch that is a different model than the rest.
