Polycom VIU 4350 - Manual

Connect any way you want with an all-in-one networking
and security solution for your enterprise edge
The Polycom V 2 IU 4350 converged network appliance helps reduce costs by simplifying the deployment,
management and security of converged video, voice and data networks. To begin with, it helps resolve
NAT/firewall traversal issues by performing video and voice NAT at the public/private IP address boundary,
which eliminates the security risks of other traversal methods that tunnel or “obscure” video and voice traffic
from existing perimeter security.
The Polycom V 2 IU 4350 converged network appliance employs a stateful packet inspection firewall in
combination with an application layer gateway, providing comprehensive application-aware security. This
approach enables the Polycom V 2 IU 4350 converged network appliance to dynamically provision and close
TCP and UDP ports as needed by video and voice endpoints.
Optimizing the quality of your video and voice calls is easy, as the Polycom V 2 IU 4350 converged network
appliance routes video and voice traffic via the shortest path possible to minimize jitter, latency, and packet
loss. At the same time, bandwidth not in use by video or voice is made available so that data traffic can
burst up to full line rate, maximizing WAN bandwidth. It also maximizes access link utilization while
optimizing video and voice quality using prioritization, traffic shaping, call admission control, and diffserv
marking/policing.
For small and medium office connectivity, the Polycom V 2 IU 4350 converged network appliance provides an
Ethernet WAN port and software-selectable, integrated T1 CSU/DSU interface This allows you to use
it either as your WAN access router, or install it behind an existing WAN access router.
