WAN optimization is a collection of techniques for increasing data-transfer efficiencies across wide-area networks.
Diginet or leased line services are dedicated point-to-point connections providing the user with an always on service.
ADSL (Asymmetric Digital Subscriber Line) is an access medium that provides the user with a broadband connection to Telkom’s data network.
A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two.
