i.
What is IP VPN Service?
VPN is an acronym for Virtual Private
Network. An IP VPN Service offers exclusive and
private interconnectivity using Internet protocol to computers or Local
Area Networks (LANs) across the country.
ii.
How can the IP VPN service benefit businesses?
Business companies can extend their LANs
and computers at various locations across the country so as to interconnect them
over an IP VPN thereby enabling online
communication, which can enhance business efficiency.
iii.
Why do enterprises need VPN?
Some of the important reasons
why enterprises need VPN are:
· High Cost & Complexity of
Private Networks on leased line – deployment, maintenance, upgradation &
expansion. These investments divert the main focus from the core business areas
of the enterprise.
· Increasingly dispersed
mobile workforce requires constant contact with the enterprise LAN. This is
possible through Dial-VPN service, which is a small value added service over the
VPN platform.
· Flexible reconfiguration
allows instantaneous addition/deletion of connections without any major
investment.
·
Rise in Internet based
applications & continually evolving technology allows the enterprise to avail of
several value-added services that will be offered by the Service Provider in
future over the same IP network infrastructure in a cost effective manner.
Examples are bandwidth on demand, VoIP, multicasting, & interactive
applications.
iv.
What is special
about the IP VPN service?
IP VPN service provides businesses
with an opportunity to outsource their communication requirements to a Service
Provider (SP) in a cost effective
manner. The predecessor of the IP VPN service is the conventional private
network which forces businesses to make significant investments in leased lines,
communication solutions and skills that are not necessarily in line with their
core activity.
v.

vi.
How does IP
VPN service compare with the conventional leased line
network model cost-wise?
The overall cost of availing a VPN
service decreases as the number of sites in a particular VPN increases. In
general, there is a significant cost
savings in opting for IP VPN service. Our marketing team will be pleased
to present a detailed business case for deciding whether you should opt for IP
VPN service.
vii.
How reliable is the IP
VPN service vis-à-vis the Leased Line model?
The IP VPN service is implemented
over a high capacity (STM-1) dual layer robust MPLS Network that has inherent
redundancies in routing capability guaranteeing specified service levels. The
overall service levels offered with IP VPN service will be
superior to service levels
derived from the Leased Lines solution.
viii.
Can you provide
interconnectivity between two VPNs?
Yes, a VPN can be provided access
from another VPN if this additional service is required by the subscribing VPNs.
This service is called “extra-net”
service.
ix. Can
you provide interconnectivity between a VPN and dial customers?
Yes, a dial customer can be
provided access to a VPN through what is known as an L2TP tunnel.
x.
How secure is IP VPN service?
A VPN by itself is an isolated
entity and therefore has no
possibility of outside intrusion. The security in case of
interconnection with other networks will be the customer’s responsibility.
