The Next Generation Network provides connectivity to the more than 3359 government sites across South Africa. The NGN provides government departments with better response times and a higher quality network. In addition it enables SITA to deliver customer services quicker, whilst the ability to plan capacity and profile network traffic ensures that the organisation can allocate bandwidth more efficiently.  The structure of the NGN has also translated into lower operational and equipment costs. To maximise the investment from the NGN, SITA established hi-tech Network Operations Centre (NOC) that pro-actively monitor wide area network services to guard against infiltration by malicious data and attend to incidents speedily. The SITA NOC has one of the largest installed video walls in Africa. SITA is also able to provide its clients with a multi-functional suite, focused on the different classes of virtual private networks, VIOP service and video streaming and gives government an important competitive edge.
