Demonstration of P4-Based In-Band Telemetry for OSM-Orchestrated 4G/5G Testbeds

Demonstration of P4-Based In-Band Telemetry for OSM-Orchestrated 4G/5G Testbeds
The SimulaMet OpenAirInterface VNF provides an OpenAirInterface-based Enhanced Packet Core (EPC), with separate VDUs for HSS, MME, SPGW-C and SPGW-U. To allow for advanced in-band telemetry, we have extended this VNF to add switches with Programming Protocol-independent Packet Processors (P4) to all relevant virtual links inside the EPC. P4 allows full programability of the packet forwarding behaviour, and especially allows to extend packets with additional information for in-band telemetry. This information can be read by other P4 instances to allow for fine-granular performance data collection. In this presentation and live demonstration, we would like show the solutions chosen to efficiently use OSM for handling our extended EPC, and in particular we would like to highlight the possibilities to perform P4-based in-band telemetry to evaluate the performance of the mobile network. Finally, we would also like to show the audience a live demo of our testbed setup with telemetry collection.

Integrating Cloud-RAN with Packet Core as VNF Using Open Source MANO and OpenAirInterface

Integrating Cloud-RAN with Packet Core as VNF Using Open Source MANO and OpenAirInterface
The Cloud-based Radio Access Network (Cloud-RAN) architecture and Network Function Virtualization (NFV) are key enablers to building future mobile networks in a flexible and cost-efficient way. 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.

Experimentation in Controlled and Operational LTE Settings with FLEX-MONROE
This demo paper presents FLEX-MONROE, a platform that facilitates better understanding of current LTE Mobile Broadband (MBB) networks and enables performance improvements by allowing experimentation with controllable LTE parameters. The platform enables investigating impact of low-level network parameter tweaks in LTE infrastructure on the application performance. We argue that FLEX-MONROE is crucial to provide guidelines on improving application performance both in the current and future MBB networks.

FLEX-MONROE: A Unified Platform for Experiments under Controlled and Operational LTE Settings
This paper presents FLEX-MONROE, a unique platform that facilitates achieving a thorough understanding of LTE networks, one that captures the status of current operational MBB networks and that also enables LTE performance improvements by allowing experimentation in an environment with controllable LTE parameters. Using this platform, we propose to investigate how variations in the LTE network parameters infuence the network characteristics, which, in turn, translate to application performance metrics that represent the end-user experience. We argue that the FLEX- MONROE platform is crucial to understand, validate and ultimately improve how current operational MBB networks perform, towards providing guidelines for designing future 5G architectures. Furthermore, understanding the effects of low-level tweaks in network parameters in the LTE infrastructure on the application performance is critical to provide guidelines on how to improve the application performance in the current but also future MBB networks.
