A VPN (Virtual Private Network) creates a secure network for branches / mobile workers / businesses to connect across public networks such as ADSL or fibre.
This gives businesses all the benefits of local network only without the costs of having to manage, maintain or upgrade it themselves.
Staff can access centralized services like intranets, extranets, VoIP, email, Internet browsing, CRM and ERP systems.
MPLS (Multiprotocol Label Switching), which can be incorporated into a VPN, is a high performance technology that carries data from one network node to the next, enabling larger organisations to manage bandwidth in real-time at a protocol level. Existing disparate networks using voice, video or combined data can be consolidated into a single end-to-end infrastructure, for completely centralized Internet access.
Unlike other large network environments, MPLS-enabled VPNs are virtually unlimited as to the number of sites they can reach, making it quick and easy to deploy many value-added services. They also have the flexibility to divert and route traffic around link failures, congestion, and bottlenecks.
