Workshop on Architectures, Services, and Applications for the Next Generation Internet (WASA-NGI)


5th International Workshop on Architectures, Services and Applications
for the Next Generation Internet (WASA-NGI-V)


A rapidly changing application landscape poses new challenges to the Internet infrastructure. New Web2.0 applications like social networks allow users to interact and cooperate pervasively in business and leisure. The integration of sensors and RFIDs in objects of everyday life has enabled an intelligent interconnection of real-world objects—the Internet of Things—at the scale of billions of devices. Although these applications foster the trend towards a “Next Generation Internet”, the transition from nowadays solutions raises many important questions, which are of concern to both industry and academia.

On the one hand, new applications call for in-network support of specific communication services, e.g., publish/subscribe or group communication. Ideally, these services should meet user's non-functional requirements, e.g, in terms of security and quality-of service.

On the other hand, new and evolving Internet applications generate massive amounts of data. For instance, Web2.0 applications require transport of rich multimedia content, while applications from the Internet of Things require processing of real world sensing data collected on a global scale.

Mobility of users and devices increases due to new access networks such as LTE and WiMax and requires migration of both services and data. Upcoming exhaustion of IPv4 addresses and introduction of IPv6 increase the protocol heterogeneity for such scenarios, thus complicating connectivity for such applications.

Recent advances in network virtualization and self-organizing service overlays provide appealing solutions to trim the Internet for these requirements. However, despite of the rapid progress in both areas they only face limited deployment in real-world applications. To bridge the gap between conceptual work and real-world deployment, challenges and requirements must be revisited from the application's point of view.


The event is organized by the SpoVNet (Spontaneous Virtual Networks) project, funded by Landesstiftung Baden-Württemberg. The workshop program is composed of presentations from practitioners as well as researchers with expertise and experience with regard to the challenges of the Next Generation Internet.
