In private local area networks (LANs), IP-based intranets have fundamentally changed the way companies conduct their business. Companies are moving their business applications to their intranets to extend over a wide area network (WAN). Also businesses of all types and sizes are facing the challenge of integrating data, voice and video traffic into easily managed, scalable, economical and flexible networks.

Virtual Private Networks (VPNs) have emerged as a fundamental solution for meeting these challenges and business customers are now looking to service providers for value-added, cost-effective VPN services.  With SLT IP VPN, you will have your own private network using our islandwide coverage of fibre-based IP backbone which will be managed to agreed levels of service. This frees your organization to concentrate on strategic business areas.


Advantages of SLT IP VPN
  • Convergence

    IP VPN provides seamless integration of voice and data networks under one IP network infrastructure, with the ability to customize IP VPN services for each business customer, thereby increasing differentiation and adding value through bundled services for data, voice, video, network security and other options. 

  • Security

    Each VPN on a single physical infrastructure is treated as a logically independent routing domain, allowing end-users to use private and unregistered IP addresses to secure their data as it travels through your network.

  • Reliability

    Network redundancy and fault-tolerance ensure service availability. Sri Lanka Telecom’s highly redundant backbone ensures reliability of the IP VPNs. SLT’s MPLS core and access networks are based on a high-speed Ethernet ring architecture which gives very high redundancy for VPNs.

  • Cost effectiveness

    Previously, network connections between sites required dedicated circuits or private virtual circuits (PVCs). MPLS-based VPNs provide access to the entire IP network with any-to-any connectivity. This will reduce connectivity charges due to the sharing of infrastructure. 

  • Scalability

    MPLS-based network architecture easily adapts to growth in complexity and volume. Since the  VPN network is any-to-any by default, VPN network expansion can be achieved with minimum additional expenses.

  • Flexibility

    VPNs can be developed with different applications such as Full-Mesh topology for voice and Hub-and-Spoke for Internet access.

  • Intranet

    IP VPNs can create an intranet that links a corporate head office to remote offices over a shared network and offer a cost-effective alternative to traditional leased-line, ATM and Frame Relay technologies.
