How will IP VPN Benefit My Business
IP VPNs can create an intranet that links a corporate headquarters to remote offices over a shared network allowing users to gain access to secured corporate information
Extranets support business-to-business communications enabling an enterprise to be connected with other enterprises, customers, suppliers or business partners.
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.
IP VPN provides seamless integration of voice and data networks under one IP network infrastructure, with the ability to customize VPN services for each business customer thereby increasing differentiation and adding value through bundled services for data, voice, video, network security and other options.
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.
Network redundancy and fault-tolerance ensure service availability. Sri Lanka Telecom's highly redundant backbone ensures reliability of the IP VPNs. SLT MPLS core network based on DPT technology and access rings based on POS gives very high redundancy for VPNs.
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.
VPNs can be developed with different applications such as Full-Mesh topology for voice and Hub-and-Spoke for Internet access.
Class of service
IP VPNs incorporate the ability to provide advanced Class of Service (CoS) features that ensures network priority for mission-critical traffic, allowing businesses to choose the appropriate CoS for their specific traffic patterns and business requirements.
