Polycom Video Border Proxy (VBP) 4555

Polycom Video Border Proxy (VBP) 4555 Series

The all-in-one networking and security solution to give an edge to your enterprise

By performing video NAT at the IP address boundary, the VBP 4555 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 E1 CSU/DSU interface, the VBP 4555 appliance can be utilised as a WAN access router or installed behind an existing WAN access router.

The VBP 4555 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 4555 appliance forwards video traffic via the shortest possible
path, effectively minimising jitter, delay, and packet loss.
