What is VPN?
A Virtual Private Network is defined as a network whereby customer connectivity amongst multiple sites is deployed on a shared infrastructure with the same policies as a private network. The main function of a VPN is to facilitate connectivity between a remote customer's sites securely, with quality of service built in.
A Virtual Private Network is an overlay network deployed on top of another network (physical network) where the two networks are separate and never communicate. A VPN uses encryption to permit organizations to establish secure, end-to-end connections over a third party network, such as the Internet. The VPN helps preserve data confidentiality and integrity.
Technologies used to build VPNs:
Multi-Protocol Label Switch (MPLS)
Vodacom Business’ VPN service is based on an MPLS (Multi-Protocol Label Switching) platform which is the next-generation network infrastructure combining flexible any-to-any communication found on the Internet with the reliability, quality and security similar to that found in privately owned and managed networks. As a technology, the MPLS ensures that the customer’s traffic is efficiently transported over the service provider’s network infrastructure. Whilst it achieves this, it also guarantees traffic separation which occurs without any form of tunnelling or encryption, because it is built directly into the network itself.
VPN service types and costs
We offer VPN services on multiple Internet access mediums, including Leased Line, Fibre, Microwave, Satellite, ADSL and mobile.

Please note:
Traditional routing | MPLS routing |
Every packet routed independently as if it's the only packet | Combines traditional routing with label forwarding |
Each router does a look-up and forwards each packet to the next hop | The path/route through the network is established upfront and labelled by Vodacom Business. |
The path/route is established hop-by-hop for every packet | Packets belonging to that path are labelled at entry to the MPLS network. |
Traffic flow through network is determined by the routers | Forwarding decisions then made on label only – no routing table lookups |
The routers decide the path the packet will take through the network | Provides customers with managed bandwidth over service provider`s network. |
