Project SENDATE-TANDEM

Abstract

TANDEM is sub-project from the CELTIC+ SENDATE project.

“TANDEM” addresses the challenge for a new network infrastructure with reference to high volatile data traffic of mobile linked up objects. A dynamic switching and a reliable transport of huge amounts of data as well as a handover of sensible, time critical application data without any interruptions must be provided between data centers.

Within the metro area, essential elements are virtualized: integrated nodes consisting of traditional DCs (RAM, processor) but also e.g. virtualized DSL- and radio access (vRAN) network elements or IP-router and optical network elements like cross-connects. Virtualization shall lead to a flexible arrangement of single modules and to a dynamic provision of resources according to application demands. Here latency and bandwidth but also QoS classes and findings from simulative traffic investigations will be considered.

Furthermore a common SDN-based control-plane will be developed for an optimized control of network elements across levels. The first underlying assumption is based upon a flexible control plane and develops an application, which is able to migrate the network from one load status to another. The second assumption goes for full flexibility from scratch within definition of control plane architecture, intending to turn today’s metro networks into a flexible platform for future services and applications.

Through a distributed infrastructure the security-related outage shall be improved, because resources of local distributed DCs are available as fallback in case of failures. Finally integrity of network elements will be investigated to protect and observe configuration data and log-files with forensic methods in a way, that in case of doubts after intrusion one can verify manipulations anyhow. The findings will be applied to a virtual communication-based Internet of Things network.
