Secure Communication
Networks are being used in new ways: user expect excellent connectivity everywhere, all the time. MPLS technology can provide this, but standard Internet lines are often sufficient and less expensive. In addition, companies are increasingly using public cloud computing, which means network data is increasingly being transmitted over the public Internet. To cut costs, traffic offloading solutions are an increasing focus. These solutions make it possible to use free capacities from Internet backup bandwidth in regular operations. A secure Internet link is configured as an additional, permanent transmission channel and used for applications with lower communications demands, for backup cases and to smooth peak loads. This enables the cost-optimized utilization of existing resources. Therefore, we will see the increasing deployment of hybrid networks in future, consisting of MPLS (multi-protocol label switching) and Internet VPN. The rapid growth of data traffic is putting an increasing strain on conventional networks. The Cisco Visual Networking Index™ predicts that IP traffic will double between 2016 and 2019. This means annual, global IP traffic will pass the two zettabyte mark by 2019. Factors in this growth include desktop videoconferencing, IP telephony and the increasing popularity of HD video. Companies want to give their employees access to these modern communication resources, of course, but these high-bandwidth apps put a heavy load on the IP VPN infrastructure, hindering access to mission-critical applications.
