Re: [Primus] Which Router for Lingo?

Does your Cisco have QoS?

Yeah, 3 classes of data + one of VoIP...
Still having trouble forcing the router to fragment low priority data packets cause they can cause serialization delay in some cases, but otherwise, it's all good.

That's interesting that it's broken down by voice and data. The SonicWall allows bandwidth management for each rule you set up. So, for example, I can set up an RTP rule allowing inbound traffic on port 13456 to go to the ATA, and as part of this rule I can specify a Guaranteed Bandwidth (in kbps), a Maximum Bandwidth, and a Bandwidth Priority.

well, I assigned 72Kbps of bandwidth to Voice traffic (teamspeak server, skype and lingo). the VoIP class is using Low Latency Queuing.
The rest of bandwidth is broken down 60/30/10% with different traffic going into one of the 3 classes, and the 3 data classes are using WRED as queueing mechanism.

I also recolor the traffic within each of the data classes when it gets above the assigned bandwidth, making it more likely to get killed by the queueing engine in case congestion approaches...

I could configure one class per traffic type, but I wanted to save my brain Plus I figured I didn't really need that much control

It's practically plug-and-play, LilYoda.
