1. Bandwidth on Demand – Not possible (Dynamic Bandwidth allocation not possible)
2. As the organization grows, number of links becomes more. Network becomes more complex and it becomes difficult to maintain the reliability.
3. As the organization grows present networking solution becomes costly since we will have to invest on Multiple links and Networking equipments.
4. Security, Maintenance of Network Elements is customer’s responsibility in present scenario.
5. Provisioning & Commissioning time is more.
Limitations of the present Limitations of the present scenarioscenario

Why MPLS based VPNs?
Why MPLS based VPNs ?
Mobile workers can dial up on a secure network to access company information.
Flexible reconfiguration (Instantaneous Addition and Deletion possible).With Growing Internet Based Applications MPLS VPN becomes a necessity.
High Cost & ComplexitySmall Offices – Minimum Links. As the sites increases – the number of links increases and thereby the Cost and Complexity of Network.

Cost comparison with other services (Leased circuits)
The cost of Connecting 9 branch offices to 1 head office at Mumbai will cost Rs. 10.33 Lakhs for 9 links and will increase proportionately till 1 Crore for node to node connectivity. The Cost of Implementing the same with MPLS Solution will be Rs. 7.3 Lakhs.Advantage: huge cost savings and additional advantages of security,reliability,scalability,flexibility and a technology which can support all IP services.

FAQs what are the benefits to the IP based customers ?
Traffic Engineering: the ability to set the path traffic will take through the network, and the ability to set performance characteristics for a class of traffic.VPNs – Using MPLS, service Providers can create IP tunnels throughout their network without the need for encryption or end user application.Layer 2 Transport: New standards being defined which will allow to carry Layer 2 service including Ethernet, FR, ATM etc.
Leading Applications for Site-to-Site VPNs
Cost-effective way to increase remote site bandwidth using DSL or cable.Extend connectivity to smaller offices.Replace high cost frame relay or private line links – international and long-haul.Increase security for frame relay or private lines.Backup network for frame relay.Service provider managed CPE services.Service provider network-based VPN services.
FAQs How is QoS controlled in a Network based VPN ? As providers towards MPLS, where will this leave the Network Based VPN Routers ?
Bandwidth Management and Traffic shaping services can be offered in Network Based VPNs.In future, MPLS Tags can be applied at the edge of the Network Based VPN & QoS parameters can be configured for the VPN.The virtual router in the IP services platform will play the role of an MPLS enabled access router.
FAQs Can I view multicast content through our VPN?
Yes MPLS VPN supports multicast
