The tagline “IT meets Telecom” captures the increasing trend in building and operating of networks to separate functions from their underlying hardware. This separation allows network operators to move from specialised, proprietary hardware to general off-the-shelf computing systems, which in turn run the network functions as software on virtualised operating systems.
Technologies such as Network Function Virtualisation (NFV) as well as Software-Defined Networking (SDN) are the enablers for this transformative trend with promises ranging from decreased CAPEX and OPEX over increased fluidity in meeting demand for network services (in collaboration with application-level providers) to emulating entire systems in software only for capacity and extreme event planning as well as lowering barriers to entry in terms of new functionality being introduced in networks by virtue of merely deploying a software-realised function rather than a specialised hardware element. Such virtualisation does not come without challenges though, in particular in areas of interoperability and integration as well as in scale and dealing with extreme event scenarios.
In this SIG, we explored these potential use cases, both from a short but also long-term perspective, separating myth from reality, as well as opportunities from hype, and brought together practitioners in this space to exchange their views and meet those who wanted to understand how the future of network operations will look like.
The Virtual Networks SIG is now part of the Mobile Networks SIG.
