	abstract = {Open Source MANO is a helpful tool to manage and orchestrate the instantiation of core network setups, like Network Service (NS) instances of our SimulaMet OpenAirInterface Virtual Network Function (VNF) for Enhanced Packet Cores (EPC). We furthermore extended our NS with VNF instances of Programming Protocol-independent Packet Processors (P4) switches, in order to allow for in-band telemetry. With in-band telemetry, it is possible to flexibly add, process, and remove telemetry information to traffic within the packet core, in order to allow for fine-granular evaluation of the system performance and the users{\textquoteright} experienced quality of service. In our presentation and demo, we would like to provide an overview of our ongoing work on P4-based in-band telemetry in an OSM-orchestrated 4G core, which is used for detecting performance problems and anomalies in the network based on machine learning. We would furthermore like to demonstrate the details of our setup to the audience in a live demo.},

	abstract = {Network Function Virtualization is a key enabler to building future mobile networks in a flexible and cost-efficient way. Such a network is expected to manage and maintain itself with least human intervention. With early deployments of the fifth generation of mobile technologies {\textendash} 5G {\textendash} around the world, setting up 4G/5G experimental infrastructures is necessary to optimally design Self-Organising Networks~(SON). In this demo, we present a custom small-scale 4G/5G testbed. As a step towards self-healing, the testbed integrates four Programming Protocol-independent Packet Processors (P4) virtual switches, that are placed along interfaces between different components of transport and core network. This demo not only shows the administration and monitoring of the Evolved Packet Core (EPC) VNF components, using Open Source MANO, but also as a proof of concept for the potential of P4-based telemetry in detecting anomalous behaviour of the mobile network, such as a congestion in the transport part.},

	abstract = {5G, the fifth generation of mobile broadband networks, is going to make a large range of new applications possible. However, further research is necessary, and the basic step, i.e. setting up a 4G/5G testbed infrastructure, is a complicated and error-prone task. In this abstract and poster, we introduce our open source SimulaMet EPC Virtual Network Function (VNF), as an easy way to set up a 4G/5G testbed based on Open Source MANO and OpenAirInterface. We would like to showcase how a researcher can use our VNF as part of his own research testbed setup. Therefore, the focus is particularly on the user interface details and features of the SimulaMet EPC VNF.},

With early deployments of the fifth generation of mobile technologies - 5G - around the world, setting up 4G/5G experimental infrastructures is necessary to optimally design 5G networks. In this demo, we present a custom small-scale 4G/5G testbed based on OpenAirInterface and Open Source MANO. The testbed integrates a Cloud-RAN based on switched Ethernet Xhaul and functional splitting, with an Evolved Packet Core (EPC) deployed as a Virtual Network Function (VNF) in a cloud infrastructure. Using Open Source MANO, this demo shows the administration and monitoring of the EPC VNF components. Moreover, as proof of concept, collection and visualization of telemetry will be shown for two smart-phones connected to the network through the Cloud-RAN.},
