Edgemarc-Bandwidth Control

Traffic Shaper

Traffic shaping is the control of network traffic in order to optimize or guarantee performance, low-latency, and/or bandwidth. Traffic shaping deals with concepts of classification, queue disciplines, enforcing policies, congestion management, quality of service (QoS), and fairness.

Given that bandwidth is a limited resource, traffic shaping allows the prioritization and management of network services. It can be used to prioritize realtime traffic over bulk traffic. For example, realtime traffic such as voice and video should be prioritized over bulk data traffic such as web and email. High priority packets can be differentiated from low priority packets by a Differentiated Services Code Point (DSCP) value in the TOS field of the IP header. This value is configurable and will automatically be applied to packets processed by the VoIP ALG.

Configure Downstream and Upstream Bandwidth

To enable traffic shaping, check the Enable Traffic Shaping check box. Then enter the Downstream and Upstream bandwidth values for your WAN connection in kilobytes per second (Kbps). By default, these values are set to 1450 Kbps for a T1 link.

By default the Edgewater from Phone Power is set with values of 6000kbps download and 600kbps upload.

You will want to configure this to match your own Internet connection speed upload and download if you are having call quality issues due to a lack of available throughput.
