Mobile phones and tablets can be considered as the first incarnation of the post-PC era. Their explosive adoption rate has been driven by a number of factors, with the most significant influence being touch-screens, sensors, app markets, and better cellular technologies.

Economic forces behind the Internet evolution have diversified the types of ISP (Internet Service Provider) interconnections. In particular, settlement-free peering and paid peering proved themselves as effective means for reducing ISP costs. In this paper, we propose T4P (Transit for Peering), a new type of hybrid bilateral ISP relationships that continues the Internet trend towards more flexible interconnections at lower costs.

The future Internet needs to provide enough flexibility to allow the dynamic deployment of new network protocols, support heterogeneous end-systems, provide novel communication abstractions, and exhibit inherent security and manageability. In this talk, I present an overview of various technological drivers that shape current developments in network architecture research. I will discuss how programmable routers and network virtualization provide the basis for adaptability in the network and present some of the related research problems. I will also provide an overview on ongoing research projects that aim to provide novel network architectures that may become the core of the future Internet.

We study the detection of the provider-free AS set (PFS), i.e., the set of those Autonomous Systems (ASes) that reach the entire Internet without paying anyone for the traffic delivery. Using trustworthy but non-verifiable sources for sanity checks, we derive the PFS from public datasets of inter-AS economic relationships. Whereas a straightforward method for extracting the PFS performs poorly because the datasets are noisy, we develop a more sophisticated Temporal Cone (TC) algorithm that relies on topological statistics and exploits the temporal diversity of the datasets. The evaluation shows that our TC algorithm detects the PFS with a high accuracy.

It is common practice for network operators, usually for traffic engineering purposes, to propagate more specific prefixes (overlapping prefixes) along with shorter prefixes that cover them. On the other hand, it can be beneficial for some Autonomous Systems (ASes) to filter such overlapping prefixes.

Wireless networks importance for the Future Internet is raising at a fast pace as mobile devices increasingly become its entry point. However, today's wireless networks are unable to rapidly adapt to evolving contexts and service needs due to their rigid architectural design. We believe that the wireless Internet's ability to keep up with innovation directly stems from its reliance on the traditional layer-based Internet abstraction. Especially, the Link Layer interface appears way too abstracted from the actual wireless access and coordination needs.FLAVIA fosters a paradigm shift towards the Future Wireless Internet: from pre-designed link services to programmable link processors.

ISPs (Internet Service Providers) typically operate as commercial ASes (Autonomous Systems) and obtain revenue by delivering IP (Internet Protocol) traffic of their customers. In particular, the provider-free ASes - which reach the entire Internet without paying anyone for the traffic delivery - sell IP transit to numerous other ASes. IP prefix deaggregation gives the deaggregator some control over Internet traffic flows but increases the memory requirements of IP routers.
