The emergence of IP VPNs as a mainstream WAN service is inevitable, according to analysts Frost & Sullivan.
Nitin Bhat, telecomms services industry manager for the company, said that, ultimately various WAN services will co-exist with IP-based VPN services; only the "pace and degree" would vary across the Asia-Pacific region.
The analysts' recent research -- Asia Pacific IP VPN Market -- revealed staggering growth in Asia for IP VPN, reaching a compound annual growth rate of 55.5 per cent between 2001 and 2008.
The reduced total cost of ownership, rather than just the cost savings in the service tariffs on legacy WAN services will drive the sector, Bhat said.
"Enterprises will find the value offering from IP VPN services high - more so as setting up fully meshed network topologies at relatively affordable cost is now possible."
