Future Internet and Network Planning

Future Internet

 

The Internet has become a crucial part of the infrastructure for our society and plays a role in nearly all private and commercial activities. The fundamental architecture and the basic protocols of the Internet, TCP and IP, have been designed over 30 years ago. However, more recent developments such as the proliferation of smartphones, services such as Voice over IP (VoIP) and Video on Demand (VoD) and the evolving Internet of Things, connecting billions of sensors and devices to the Internet, put requirements on the Internet it was never designed for.

 

The crucial questions is, if the Internet can satisfy future needs. Therefore we on one side address the deficiencies of the current architecture, such as mobility, high traffic demands, quality of service and security. by developing new architectures, protocols and mechanisms for the next generation Internet. On the other side we are investigating, how we would develop the Internet today with today’s technology and knowledge on applications.

 

Two major approaches are considered by us at the moment:

  1. Information Centric Networking (ICN) is a promising concept for the Future Internet based on naming content as opposed to naming hosts as in TCP/IP. Naming content enables in-network caching for efficient content distribution and simplifies multihoming. Our current work focuses on mobility and handover support as well as new routing schemes for ICN architectures such as Content Centric Networking (CCN).
  2. Network Virtualization, isolating different networks from each other, offers an opportunity to migrate from existing IPv4 based networks to new technology and approaches such as ICN based architecture.  Software Defined Networking (SDN) with Open Flow can be seen as a first step in this direction, as it reserves resources for flows. Network virtualization would go beyond this and reserve physical resources for networks – this should also include computing and caching resources

Network Planning

 

Network planning and optimization addresses all activities related to network development, operation and evolution, classified by different time-scales. Long term activities are to design or expand the network to meet the requirements for a long period of time, usually years. These include, for example, physical topology design and capacity expansion. Medium term activities include actions that need to be done weekly or monthly to achieve the convergence towards the established long term goal. Short-term activities (real-time to hours) incorporate immediate operations such as restoration upon failure or dynamic routing.

 

Network planning and optimization is an old but never outdated topic in telecommunication networks. The explosive growth of traffic volume and the rapid development of new services as well as network architectures and technologies have continuously raised new challenges for network planning and optimization. In the Institute of Communication Networks, we deal with the following (but not limited to) problems of network planning:

 

- Quality of Experience (QoE)-based network planning

- Multilayer network planning 

- Stochastic network planning

- Network planning for future networks and the Future Internet
