VoIP must provide the same level of quality as traditional, circuit switched telephone lines. Service availability is critical for the perceived quality of VoIP. Hence a high degree of availability is a design goal for IP telephony applications and the underlying network elements. Implementing highly available applications and the corresponding network nodes is a challenging task and needs to be supported by adequate tools and run-time environments in a standardized way. Come see examples for the type of support needed such as clustering or checkpointing, specifically Linux clusters. A number of foundational characteristics of Linux clusters are needed to support the carrier-grade levels of availability and scalability in Internet telephony. You’ll also get a look at Service Availability Forum standards like AIS and HPI.

How New VoIP Silicon Will Transform IP-PBX Architecture

Wednesday - 02/23/05,  11:15-12:00pm

Presented By: Michel Laurence, Chief Executive Officer, Otasic

Early Voice over packet (VoP) silicon enabled gateway equipment vendors to bring packet voice to network infrastructures. Now, as VoP has become a reality, next-gen System-on-Chip (SoC) silicon must be developed to push that envelope further, allowing access equipment vendors to deliver optimized architectures for both legacy voice and new services. This session will discuss VoP architecture design challenges, including space and power concerns, and how next-gen silicon can address those concerns. Get solutions to those challenges using SoC silicon that permits ease of integration, lower power and uses less space. Finally, you’ll learn how variable density SoC devices can revolutionize voice gateways by allowing equipment vendors to use a single device to develop across many gateway platforms.
