2 Fraunhofer Institute FOKUS and TU Berlin AV AV provides education and applied research together with Fraunhofer Institute FOKUS Education & Research 2

3 FOKUS OpenEPC Platform Based on the success of the Open IMS Core, is developing a NON- OPEN SOURCE EPC platform, enabling academia and industry to integrate various network technologies and integrate various application platforms into a single local testbed, thus lowering own development costs This platform can be used to perform R&D in the fields of QoS, Mobility, Security, Management OpenEPC implemented features are aligned with 3GPP specifications: adaptable to different deployments extensible to specific research needs configurable highly performance More information: 3

4 Competence Center NGNI 4 Software solutions for network path and quality monitoring Utilizes sampling approach to keep up with increasing data rates Based on measurement standards (IPFIX) utilized in major Future Internet testbeds: Planetlab, VINI, Federica, G-Lab More information: wwww.fokus.fraunhofer.de/go/track

5 Packet Tracking and EPC? Network operators will face additional challenges with the introduction of LTE Packet tracking can offer solutions for provider challenges Multiple access technologies make debugging and network optimization difficult Packet Tracking visualizes network paths and captures bottlenecks (delay, loss) increased data rates require highend measurement devices for full traffic capture Packet tracking uses synchronized packet sampling to decrease measurement overhead Introduction of new network services with guaranteed QoS parameters require SLA validation Packet tracking enables the validation of QoS parameters on operator side 5

6 Demo Scenarios Handover Monitoring: WiFi/ UMTS Bearer Monitoring: QoS specific bearers 6

21 OpenEPC Technical Aspects OpenEPC is a software implementation of a set of standard EPC components which permits the cost efficient establishment of testbeds to prototype, measure, test and perform research developments in the area of future wireless networks. OpenEPC is both IPv4 and IPv6 compatible and its components have been developed in C under Linux for high performance. All OpenEPC components have been designed to be: configurable allowing easy modification of the behavior of components and the inclusion of optional features. customizable and extensible permitting the set-up of different environments and adapting to new requirements that may appear within standardization process reliable based on the know-how gained in previous component development like the Open IMS Core project aligned with standards implemented components can be used for testing other commercial EPC components as well OpenEPC can be deployed on standard commercial off-the-shelf hardware running Linux 21
