Polycom VBP 5300-E10 2583-73553-005 Manual De Usuario

Polycom Video Border Proxy (VBP™) solutions allow video 
conferences to securely traverse firewalls, while retaining
complete network security.    

Users of standards-based high definition video endpoints such as the Polycom HDX series can now remotely

and securely communicate over video on enterprise or service provider networks. 

By performing video NAT at the IP address boundary, Polycom VBP solutions forward video traffic via the

shortest path possible to minimize jitter, delay, and packet loss.  Polycom VBP solutions fully protect H.323

gatekeepers, video endpoints, and multipoint conference platforms from attack, while safeguarding 

video quality. 

Polycom VBP series also optimize video conference quality through traffic management features such as 

prioritization, traffic shaping, call admission control, and diffserv marking/policing.  In addition, the Polycom

VBP series enhances network security with an H.323-aware packet inspection firewall that opens and closes

TCP and UDP ports as required.  

High-Quality, Highly Secure Video Conferencing 

Polycom VBP secure H.323 proxies enable one public IP to serve all the video communications needs, and

with availability for bandwidths from 1 Mbps to 85 Mbps, IT managers can configure the VBP series for 

centralized or decentralized dial plans. 

Polycom VBP solutions support all standards-based video endpoints and multipoint conferencing units, such

as the Polycom RMX 2000™ real-time media conferencing platform.  Models with optional H.460 support for

mobile users or remote locations without video-aware firewalls are also available. 

Solutions for All Requirements

Polycom VBP solutions provide security and firewall traversal across a wide range of enterprise and service

provider requirements, and include: 

Polycom VBP E Series – Ideal for dialing video endpoints outside the network that are not 

registered with a gatekeeper, as may be the case with a distributed dial plan. 

Polycom VBP S Series – Optimized for networks in which all endpoints are registered to a 

central gatekeeper.

Polycom VBP ST Series – The best choice when H.460-based traversal services are needed in 

conjunction with a centralized gatekeeper.
