Configuring the V2IU 4350

Traffic shaping and priority queuing to guarantee high quality video traffic. These mechanisms protect video and data traffic from contending for the same network resources to guarantee low latency and the highest call quality possible for voice and video traffic. At the same time they ensure the best utilization of WAN bandwidth by enabling data traffic to burst up to full line rate in the absence of video calls. Precedence is automatically given to traffic coming from video endpoints and other devices using the 4350’s Application Layer Gateway function.

Video NAT/PAT translation for video endpoints and PC’s. This allows a single IP address to be used on the WAN link to represent all of the private IP addresses assigned to the LAN video endpoints and PC’s.

A video aware firewall. A full layer 7 gateway for video traffic and a stateful packet inspection firewall for data traffic

Call Admission Control (CAC). CAC uses a deterministic algorithm to decide when there are insufficient network resources available to adequately support new video calls and then return the equivalent of a “fast busy” to new call requests.
