4200 User Manual Edgewater Networks, Inc. Traffic Management Configuration Traffic management is required to ensure high quality voice calls when both voice and data traffic share the same WAN link. Voice traffic must be prioritized for transmission over data traffic to meet the stringent jitter, latency and packet loss requirements for toll quality voice. The 4200: Automatically prioritizes voice traffic over data traffic to ensure toll quality voice calls.
4200 User Manual Edgewater Networks, Inc. your IT administrator or service provider can usually provide these values. Some typical examples are as follows: WAN Link T1 SDSL ADSL WAN Downstream Bandwidth 1.544Kbps 768Kbps Example 1 - 768Kbps Example 2 - 512Kbps WAN Upstream Bandwidth 1.544Kpbs 768Kbps Example 1 - 256Kbps Example 2 - 128Kbps Optionally enable priority IP addresses VoIP traffic from devices that use the VoIP ALG function (phones, video stations, softphones on Pcs, etc.
4200 User Manual Edgewater Networks, Inc. Determining the maximum number of concurrent calls The maximum number of concurrent calls that can be supported by the WAN access link is calculated using the following formula: Max calls = (Maximum WAN upstream bandwidth * .85)/VoIP codec rate where, Maximum WAN upstream bandwidth = value entered in step D above (in Kbps) VoIP codec rate = 85.6Kbps for G.711 voice devices or 29.6Kbps for G.729 voice devices. The maximum WAN upstream bandwidth is multiplied by .
4200 User Manual Edgewater Networks, Inc. A Closer Look at Traffic Management in the 4200 The traffic management mechanisms provided by the 4200 are designed to ensure high priority real time voice traffic is processed before lower priority data traffic. At the same time, bandwidth not in use by voice traffic is made available so that data traffic can burst up to full line rate making efficient use of WAN bandwidth.
4200 User Manual Edgewater Networks, Inc. if necessary) when sent to the LAN interface by the 4200 appliance. Similarly data traffic sent back to the 4200 for transmission to the WAN are also delayed. This results in the end stations slowing down their transmit rate. This technique is quite effective in practice as end stations usually reduce their transmit rate before VoIP signaling has completed for new call setup.
