Hey all, trying to setup a traffic shaper on a home network and having trouble finding the right product.
I have a T1 with a cisco router managed by the telephone company. I have several computers connected to the T1 that often saturate the connection. Problem is, I have a wireless router on one port and a latency sensitive application on a computer on the other port. When the wireless saturates the connection, my latency jumps from 34ms to 3000ms on the latency sensitive computer.
I thought QoS port prioritization on a newly purchased "Netgear ProSafe Plus Switch, 8-Port Gigabit Ethernet (GS108E)" would fix this issue simply, but I was wrong. Apparently the aforementioned prioritization only applies to swamped switch traffic and not saturated Internet up/down thru the T1(on this switch, anyway).
So, I tried using a bandwidth limiter by port on the same switch, and limited the wireless connection to 1mbps, leaving 0.54mbps for my latency sensitive application, and while this did limit the bandwidth to the aforementioned 1mbps on the Cisco wireless router, the latency sensitive computer still have terrible latency, and was even dropping packets and disconnecting at that point. I updated the firmware on the switch to no avail.
I am sending this switch back, it isn't want I need, and I'm convinced it cannot be configured to work like I need it to.
I need something that will intelligently manage INTERNET bandwidth in real time to make sure that any requests for internet bandwidth from a certain port are given unhindered access to the full spectrum of bandwidth, while maintaining low latency on the latency dependent program. I would also like this to be easy to setup and affordable. I'm not sure if there is an affordable product on the market that can meet these requirements.
Also, any ideas on why limiting bandwidth on one port would still produce high latency on the other port(should be .54mbps left over which is more than enough to ping google.com and give low latency results, but this may not be how latency works on a T1, I'm unsure).
Finally, I would like to know if there is no solid option, is there a product that will limit internet bandwidth to one port or IP without causing high latency on the latency sensitive computer.
What I need is for someone to be downloading a large file over the wireless router, but a VOIP phone connected thru another port on a swtich, to still be able to operate at full unhindered capacity on the other, over a T1, with latency that would appear as if the connection was not in use. Any suggestions?
