Sify
wires up whirlpool for international MPLS services
Background
Whirlpool of India
Limited (WOIL) was planning to shift its ERP and
other application servers to their HQ at Michigan,
US, from their present position at Delhi. Their
existing set up was made up of connecting all
WOIL locations (around 40 of them nationally)
to Sify, locally (using different mediums of dedicated
last mile connectivity, viz 2 Mbps LL, 64 Kbps
LL, BB, RF - each with ISDN back ups) and accessing
their Head Office (HO) in New Delhi, centrally.
The HO was connected to SIFY NOC on 2 Mbps LL
(primary) and BB (Secondary). Besides this, 40
PSTN dial up users also accessed their HO. Applications
running at the HO included SAP, Mail main server
and a couple of small applications. The HO also
had 256 Kbps Internet access and their Pondicherry
factory had 128 Kbps Internet access. Both these
locations used a common last mile for Internet
as well as VPN.
The
key requirements were
a) High availability
for WOIL servers at USA primarily for accessing
their SAP server (hosted in HQ, from their India
Locations), Mail Server application, other Intranet
applications and proposed VOIP or Video conferencing
b) Redundancy on
Sify's proposed Trans-Atlantic and Trans-Pacific
gateways in the case of a STM-1 failure on either
of the gateway links
c) Internet access
from their Delhi and Pondicherry offices in India
Key
concern areas for WOIL
- High uptime
commitments in the network
- Highly flexible
and scalable network solution
- Network Management
and monitoring
- End-to-end
security
- Reduced latency
on the network
Solution
International MPLS
Bandwidth requirements were proposed at 3.0 Mbps.
Currently WOIL's HO in Delhi is establishing IP
Sec tunnel with their US office, using Sify's
International bandwidth routed through the primary
path of Trans Atlantic fiber gateway in Mumbai
(Hot back-up being Trans-Pacific). The proposed
solution is an overlay network for WOIL on Sify's
IP backbone. Sify's network is MPLS (Multi Protocol
Label Switching) enabled and its partner-Beyond
the Network Access (BtNA), a premium International
service provider would be providing MPLS WAN services
to WOIL in Benton Harbor, Michigan.
Sify proposed the
Layer 3 MPLS enabled VPN from WOIL co-located
and aggregated point in Mumbai to their International
office in Michigan. The key benefit offered by
MPLS WAN is that it imparts a strong security
feature to the WOIL network. MPLS VPNs use a technique
called route distinguishers to provide traffic
separation between VPNs of different customers.
These are assigned automatically when the VPN
is provisioned, and are unique for a given customer.

Schematics for WOIL MPLS WAN Connectivity
The
critical differentiators of the solution offered
by Sify
Sify's strong value
proposition for providing International MPLS connectivity
services played a critical role in WOIL adopting
its network. Sify's critical differentiators were:
- A strong
and robust domestic backbone in India for
providing MPLS Layer 2 and Layer 3 VPN services
for enterprises with full redundancies built
at all levels, which included carrier diversity
on the backbone as well as on the last mile
- Redundant
fiber bandwidth gateways for providing high
availability MPLS VPNs to any international
destination
- Co-located
Points of Presence in Hong Kong, London, New
York, and Los Angeles while peering with premier
service providers in these locations
- Millions of
man-hours of experience in building business
critical networks for corporates in India
- Wide acceptance
- Sify's services
are used by international service providers
such as Cable & Wireless, MCI and ETT as their
preferred partners in India. And most importantly
the key benefit offered by the Sify MPLS WAN
architecture was that it imparted a strong
security feature for the WOIL International
network, besides providing WOIL with a most
cost effective solution.
