The Polycom Video Border Proxy (VBP™) 4350 network appliance allows your organization to conduct video conferences clearly and securely by resolving the challenges caused by firewalls. Users of standards-based video endpoints, such as the high definition Polycom HDX 4000™ and Polycom HDX 7000™ series, can now remotely and securely communicate over video on the enterprise network. By performing video NAT at the IP address boundary, the VBP 4350 network appliance eliminates the risks of tunneling video and voice traffic from the network perimeter. With both an Ethernet WAN port and a software-selectable integrated T1 CSU/DSU interface, the VBP 4350 appliance can be utilized as a WAN access router or installed behind an existing WAN access router. The VBP 4350W model also includes 802.11 (b & g) wireless connectivity with other network devices. The VBP 4350 appliance employs a stateful packet inspection firewall, in combination with an application layer gateway, which determines when to open or close TCP and UDP ports for video and voice endpoints. To maximize video and voice quality, the VBP 4350 appliance forwards video traffic via the shortest possible path, effectively minimizing jitter, delay, and packet loss. Bandwidth unused by video or voice is made available to boost WAN bandwidth and enable data traffic to burst at full line rate. To ensure control over video and voice quality, the VBP 4350 appliance also possesses traffic management capabilities such prioritization, traffic shaping, call entry control, and diffserv marking/policing.
