Wipro Technologies-Migration to MPLS-based WAN

With growing business needs, IT companies need improved bandwidth over their
WAN links, scalability, and with scattered IT skills, they need to ensure a
high-rate of mobility for their workforce. Keeping these concerns in mind, Wipro
decided to move from the legacy TDM-based network to an MPLS-based network.
Prior to this migration, Wipro's network consisted of point-to-point lease line
connectivity across all locations. Drawbacks of this setup included fixed
bandwidth, no scalability, network complexity, too many active components to
terminate the WAN link, and high running costs with low bandwidth. So, the
company's IT decision makers decided to go for a single service provider with
clear SLAs on uptime and latency. The migration from NLD to MPLS technology gave
benefits such as bandwidth scalability, cost saving, any-to-any communication,
quality of service (QoS) and traffic isolation among multiple clients.

The
company could also reduce the lead time interconnectivity of new offices to the
main datacenter. MPLS allows a Service Provider to have complete control over
parameters that are critical to offering its customers service guarantees with
regard to bandwidth throughputs, latencies and availability. The technology
enables secure Virtual Private Networks (VPN) to be built and allows scalability
that will make it possible to offer assured growth to its customers without
having to make significant investments. In the new design, each data center
would have two STM1 last mile with Ethernet handoff from two different service
providers. BGP routing protocol was used to route Public IP address to the
Internet. This ensured that the Internet traffic load would be distributed to
two datacenters. So, even if one data center or service provider POP went down,
Internet traffic would get routed via another datacenter. The company also put
together a virtual ODC concept on this network to enable usage of skills across
more than 35 locations in India.

Project Specs Business problem:Changing business dynamics demand more bandwidth and the flexibility to share IT resources amongst all branches IT solution:MPLS-based WAN provides increased bandwidth along with redundancy and QoS. Virtual ODC concept allows sharing of skills across different locations. Impact:The bandwidth has increased by three times, with a 20 percent reduction in costs.

This allows the workforce to access the same network resources across all
locations. This helped in addressing the high lead times of resource
fulfillment, high training costs and a high turnaround time. The complete
enterprise network has been outsourced to a managed service provider. Its
enhanced design has helped Wipro achieve 99.999% uptime.
