Third graph, third sentence of release dated March 7, 2013 should read:
Additional demand for hyperscale networking datacenters will be generated over
time by CSPs like Verizon, AT&T, BT, Orange Business, NTT Com, SingTel, and
Tata Communications. (sted NTT DATA).

SOFTWARE DEFINED NETWORKS AND LARGE-SCALE NETWORK VIRTUALIZATION COMBINE TO
DRIVE CHANGE IN TELECOM NETWORKS, IDC SAYS

Software-defined network (SDN) and large-scale network virtualization are two
emerging telecom industry technologies that will combine to drive a more
software-centric and programmable telecom infrastructure and services
ecosystem. According to new research from International Data Corporation
(IDC), these complementary and transformative technologies will have a
sustained impact on today's communication service providers (CSPs) and the way
they do business.

"IDC believes that the rapid global growth of data and video traffic across
all networks, the increasing use of public and private cloud services, and the
desire from consumers and enterprises for faster, more agile service and
application delivery are driving the telecom markets toward an inevitable era
of network virtualization," said Nav Chander, Research Manager, Telecom
Services and Network Infrastructure, IDC. "SDN and large-scale network
virtualization will become a game shifter, providing important building blocks
for delivering future enterprise and hybrid, private, and public cloud
services."

CSP networking of large data centers will be the first battleground for SDN.
Networking datacenters employing SDN-based solutions will be driven by the
requirements for hyperscale networked datacenters built by specialist cloud
providers like Rackspace, Amazon, Google, and Microsoft. Additional demand for
hyperscale networking datacenters will be generated over time by CSPs like
Verizon, AT&T, BT, Orange Business, NTT Com, SingTel, and Tata Communications.
Additionally, CSPs' ability to embrace new disruptive software platforms will
enable multivendor network virtualization.

Major CSPs have recently joined forces to establish a new Network Functions
Virtualization (NFV) group to specify a set of virtualized network functional
requirements. The goal is to reduce the number of specialized and fragmented
proprietary hardware-based network appliances or network elements and the
requirement for a physical install per appliance per site. NFV is
complementary to SDN and will be a standards-based framework to leverage
standard IT virtualization technology in telecom infrastructure.

Additional findings from IDC's research include the following:

  *Time to service agility is a key driver for SDN concepts
  *Lowering OPEX spend is a bigger driver than lowering CAPEX for CSPs
  *Network Function Virtualization and SDN will emerge as key components of
    both CSPs service strategies and telecom networking vendor's product
    strategies

The IDC study, Will New SDN and Network Virtualization Technology Impact
Telecom Networks? (IDC #239399), examines the rapidly emerging
software-defined network (SDN) market, the developments in large-scale network
virtualization, and a new Network Functions Virtualization ecosystem, which
are likely to have an impact on telecom equipment vendors' and CSP customers'
plans for next-generation wireline and wireless network infrastructure.
