… and this is especially true for IT networks and network technology. There are mainly two drivers forcing network operators (telecoms and enterprises) to constantly think about increasing network efficiency and possibilities to lower OPEX spendings:
1 Data usage growth
High-resolution video & audio streaming services and cloud & fog computing increase the amount of data that has to be transferred over both public and private networks.
2 Device count growth
In an all-connected world, trends like 5G, the IoT or BYOD are responsible for a huge increase in connected network devices and users/subscribers.
To be able to deal with this exponential growth, networks need to be flexible in order to adapt to changed network requirements in a quick and automated manner (e. g. scaling out unneeded resources at times when network usage is low). Technological concepts like SND & NFV have the goal to provide this flexibility to network operators and to abstract the network itself from the underlying infrastructure.
Traffic Analytics enabled by DPI technology provides essential information in order to evaluate the operational network status and significantly improves SDN/NFV-based concepts such as Service Function Chaining.
