The IPSec Voice and Video Enabled VPN (V3PN) Solution Reference Network Design (SRND) extends the Architecture for Voice, Video and Integrated Data (AVVID) by enabling voice and video applications to be transported over a site-to-site IPSec VPN. Just as Enterprise implementers expect to run these applications over a private WAN (like Frame Relay or ATM), they also expect to run voice and video across their VPN implementation with the same quality and level of service. Furthermore, the Enterprise implementer should be able to do so and have the VPN be fairly transparent to these applications.
To provide these capabilities, Cisco designed the IPSec V3PN, which integrates three core Cisco technologies:
The result is an end-to-end VPN service that can guarantee the timely delivery of latency-sensitive applications like voice and video.
