The Trend:
Many organisations are converging their separate voice and data networks into a single, powerful, highly flexible network. The reason for this convergence is the emergence and growth of IP Telephony: according to Frost & Sullivan, the total IP market grew by over 300% in revenue from 2000 to 2001. In fact, the Asia Pacific IP market is expected to record an annual compound growth rate of 65% by 2008. High performance and robust switching is at the heart of the new converged network in order to deliver the Quality of Service that users expect, and let you enjoy the cost savings associated with convergence.
Factors Driving the Trend:
There are many reasons to support this kind of technology adoption:
|
|
 |
IP Telephony leverages existing LAN/WAN infrastructure and capabilities. |
|
|
|
The Internet now supports call traffic with QoS matching that of traditional TDM networks. |
|
|
|
IP Telephony usage improves operational expenses without losing functionality. Trimble CIO Bob Denis noted, "Tomorrow (the Centrex provider) could walk in and say, 'we're hiking our prices by 20%.' We want to stabilise our expense base without sacrificing functionality" — and that means IPT. |
|
|
|
A single network to manage means significant savings in operational costs. |
|
|
|
Data and voice convergence paves the way for rich IP-based business applications, including unified messaging. |
The Solution:
Cisco has developed a complete IP Telephony infrastructure
built on Cisco AVVID (Architecture for Voice, Video and Data). AVVID includes
the ability to look deep into packets and prioritise them according to content
and application, providing the granular QoS and high reliability required
for VoIP. All Catalyst Series switches are integral to this infrastructure,
with specific IP Telephony modules enabling robust IP Telephony capabilities
in your network.
