Firming up the backbone really helps
Tecumseh India re-architected its campus LAN and now enjoys
better throughput, reliability, and security. by Soutiman Das Gupta
Sometimes a set of simple solutions goes a long way in helping a company save
costs, utilize the available bandwidth optimally, and exchange information in
a secure manner.
Tecumseh India's campus LANs at its two manufacturing sites were running on
legacy equipment and did not provide much by way of speed, throughput, security,
and manageability. It implemented Layer 3 switches, updated the passive components,
and thus firmed up its communication backbone. It also deployed VLANs in order
to provide security for the users in the LAN.
The company in India
Tecumseh India manufactures compressors out of two manufacturing plants in
Ballabgarh and Hyderabad. The Ballabgarh plant is spread across 25 acres and
the Hyderabad plant across 125 acres.
Tecumseh India is part of Tecumseh Inc, USA, and claims to be the largest compressor
manufacturer in the world. The company has begun exports to Middle East, USA,
Pakistan, Bangladesh, Nepal, Sri Lanka and other countries. Tecumseh's range
of compressors is used in air-conditioners, refrigerators, and commercial refrigeration
The company strives to provide prompt, accessible after-sales services, and
technological assistance. And in such a case it is critical and essential to
have a free flow of manufacturing information between its manufacturing plants
and the other offices like four regional sales offices, two branch sales offices,
nine depots, 194 registered dealers, and 600 registered assemblers nationwide.
The company's network was based on unmanaged switches and hubs using Thick
Ethernet cables. The earlier vendor did not follow the industry standards and
there was a very high rate of data collision in the LAN. This resulted in loss
of valuable data. Other than that, the backbone was subject to high latency
and frequent downtime.
Tecumseh India deployed a Gigabit LAN solution using updated hardware and passive
components. The solution design was based on Layer 3 switching technology, supported
by a fiber backbone, on a Gigabit interface for inter-departmental connectivity.
All the active components like the Layer 3 switches and the passive components
like cables were provided by D-Link and deployed by Sysware Infotech Pvt. Ltd.
A vertical VLAN in the campus buildings has been implemented for added security.
Both the locations now have managed networks and are connected through VSAT
links. An administrator can sit at any location and manage the entire network.
Rs 35 Lakh was spend to upgrade the LANs at both the sites. The applications
and database servers were centralized at the Hyderabad location. An ERP was
deployed by the company and the regional sales offices were allowed to access
the database through a VPN.
The company now enjoys the benefits of a backbone, which offers high throughput
and bandwidth, and is capable of handling increased load in future. The links
are reliable and has very little downtime. And all this has helped the company
carry out online ERP transactions with various other nationwide locations.
