The Client

The client is a large Japan based application service provider offering VPN services to a large number of customers. They were planning to have Web based advisory systems for the agents and clients in addition to the mainframe system in the Data Center. For this they should have an IDC with a business continuity site. Along with this, the client needed a solution for seamless connectivity of the employees, agents and customers.

The Challenge

The challenge to the solution lies in running IPSec VPN above the MPLS VPN client. There are multiple paths to two main sites. Client wanted to re-route VPN traffic via another IPSec tunnel in case the primary link fails. They wanted a smooth failover so that it will appear very transparent to the end users and there would be no connection failure.

The Solution

Initially, all the branches of the client were connected using 64K Frame Relay links. The client needed to upgrade the bandwidth from 64K. Wipro offered a MPLS VPN based solution, as it is a very cost-effective solution compared to leased or frame circuit. All that the client needed to do was to take only the local circuit to the service provider and share the Service Provider's gigabit backbone. Using multi protocol BGP, the client routes are propagated to the other sites. In addition to this, multiple IPSec tunnels have been configured for having encrypted communication among sites.

The client's Head Quarters, Branches, Internet Data Center and the business continuity sites are connected via the MPLS VPN. All the mobile users are connected using Cisco VPN concentrators. The Mobile users dial into the nearest ISP and connect via Internet to access the Intranet sites. The entire solution is based on Cisco products. Their Head Quarter is connected to other offices in Singapore, Hong Kong, UK etc via another VPN based solution from Checkpoint.
