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 4300T’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.
