MPLS VPN Service Design

Organization problems in network scope include the following: security issues for organization interactions, high cost of the various services and suspension in these interactions, therefore, any organization looking for a highly secure, low-cost, high bandwidth, robust networking solution for internetworking will immensely benefit from MPLS VPN. The organizations are able to integrate and optimize their networks, using this service. ERP solutions that are popular with enterprises, can easily run over the MPLS VPN network, interconnecting the various branch offices, dealers and factories with the main office being almost anywhere in the country. Being fully deployed on an optical fiber backbone, this network is secure and offers lots of bandwidth, making the network scalable. Therefore, users of this network can choose to upgrade their network to higher bandwidth when it’s required.
Our solutions for MPLS VPN service:

  • Multimedia Services: It is possible to distribute voice, video and data across the MPLS VPN network, just as it's done in a LAN environment. This service facilitates the exchange of information rapidly between the various sections of the organization.
  • VoIP: The MPLS VPN network can carry VoIP traffic, which the organizations can transit their call by using VoIP traffic.
  • Video Conferencing: The MPLS VPN network enables users to set up video conferencing with certain equipment. This service is especially popular among enterprises as it saves time and travel costs. Universities can run a virtual campus through interactive video sessions. Interconnection among universities can greatly advance the cause of research and development, as well as academic progress.
  • Data Transfer: High-speed data transfer is possible across this network. Since this is a dedicated network, the delay is non-perceptible and error free. This is an ideal solution to meet all the data transfer requirements of any organization.
  • E-mail: By setting up e-mail servers across their Internet, companies can transfer mail using the MPLS VPN network. This eliminates the need for any other type of official correspondence, while at the same time ensuring prompt delivery of information, greatly enhances the speed and efficiency of workflow within an organization.
  • ERP:. Many companies use ERP solutions for online business transactions with peer companies, dealers, customers, branch offices, factories and etc. Working online in this manner requires highly robust and congestion free networks, which is made possible by MPLS VPN networks of BSNL.
  • Intranet: There is hardly any organization, which does not have its own intranet for work flow management and for meeting their information requirements. Such intranet solutions can be run across the MPLS VPN network thus enabling integration of operations across the country.
  • Extranet: Companies may prefer to exchange information with other similar companies to speed up business transactions. The MPLS VPN network is capable of providing the extranet facility, by interconnecting the VPNs, depending on the customer's requirement.
  • Internet: Customers preferring a common infrastructure for intranet and Internet can have access to the Internet via the MPLS VPN network. However, this will be only according to the customer's preference.
  • Multicast: One of the important new features that MPLS VPN offers is multicasting. This is especially useful for applications, such as video conferencing and customer specific broadcasting.
The integration of network services is a major requirement for service providers. To establish a correct integrated network, based on MPLS VPN have lots of advantages, such as more flexibility at more cost-effective price-points than other WAN technologies, such as T1 lines. The label-switching technology offers QoS and CoS capabilities. Also, keeping your traffic on a single vendor, using MPLS VPNs give the vendor the ability to offer your company service-level agreements (SLAs) for performance evaluation, unlike the "best effort" delivery of the Internet. Fava Pars consulting firm has lots of hands-on experience in this area and can help service providers to optimize and deliver different functionality of this service.
MPLS VPN delivers value-added services, including the following:
Connectionless service: A significant technical advantage of MPLS VPNs is that they are connectionless. This means that no prior action is necessary to establish communication between hosts, making it easy for two parties to communicate. To establish privacy in a connectionless IP environment, current VPN solutions impose a connection-oriented, point-to-point overlay on the network. Even if it runs over a connectionless network, a VPN cannot take advantage of the ease of connectivity and multiple services available in connectionless networks. When you create a connectionless VPN, you do not need tunnels and encryption for network privacy, thus eliminating substantial complexity.
Centralized service: Building VPNs in Layer 3 allows delivery of targeted services to a group of users represented by a VPN. A VPN must give service providers more than a mechanism for privately connecting users to intranet services. It must also provide a way to flexibly deliver value-added services to targeted customers.
Scalability: The key deficiency of VPN service is scalability. Specifically, connection-oriented VPNs without fully meshed connections between customer sites are not optimal. Fava Pars instead use the peer model and Layer 3 connectionless architecture to leverage a highly scalable VPN solution.
Easy to create: MPLS VPN services must be easy for service providers to create new VPNs and user communities. Because MPLS VPNs are connectionless, no specific point-to-point connection maps or topologies are required. Sites can be added to intranets and extranets, which form closed user groups. When you manage VPNs in this manner, it enables membership of any given site in multiple VPNs, maximizing flexibility in building intranets and extranets.
Flexible addressing: To make a VPN service more accessible, customers of a service provider can design their own addressing plan, independent of addressing plans for customers of other service provider. Many customers use private address spaces and do not want to invest the time and expense of converting to public IP addresses to enable intranet connectivity. MPLS VPNs allow customers to continue to use their present address spaces without Network Address Translation (NAT), by providing a public and private view of the address. A NAT is required only if two VPNs with overlapping address spaces want to communicate. This enables customers to use their own unregistered private addresses, and to communicate freely across a public IP network.
Integrated Quality of Service (QoS) support: QoS is an important requirement for many IP VPN customers. It provides the ability to address two fundamental VPN requirements:
  • Predictable performance and policy implementation
  • Support for multiple levels of service in MPLS VPN
Straightforward migration: For service providers to quickly deploy VPN services, use a straightforward migration path is required. MPLS VPNs are unique because you can build them over multiple network architectures, including IP, ATM, Frame Relay, and hybrid networks. Migration for the end customer is simplified because there is no requirement to support MPLS on the CE router and no modifications are required to an intranet belonging to a customer.
