The EXTREME (EXperimental Testbed for Research Enabling Mobility Enhancements) Testbed® is a multi-purpose fully reconfigurable testbed that serves to validate networking schemes in close-to-real scenarios. Beyond the general framework, it features three specialized testbeds, one focusing on mmwave and mesh networks, another one focusing on cloud networks with SDN and NFV capabilities and the third one focusing on 4G/5G access and core networks. The EXTREME Testbed® combines the ease of management of multi-user experimental facilities with the flexibility of proof-of-concept testbeds.
Some examples of schemes developed and evaluated over the testbed are: distributed mobility management, including mobility in hetDerogeneous environments, self-organized mesh networks, cognitive networking, smart flow management, data offloading and wireless network measurements.
The EXTREME Testbed® integrates three specialized extensions. The first one is an in-building mmWave Mesh backhaul network with wireless nodes with Mobile Edge Computing (MEC) capabilities deployed in the CTTC building. The second one is a distributed cloud testbed with SDN/NFV capabilities allowing running virtual network functions (NFV) and the services of a given scenario. The third one is a 4G/5G access and core network testbed based on the LENA/ns-3 simulator/emulator.
In the recent past, the EXTREME Testbed® also integrated other specialized extensions, such as a fully operational packet switched UMTS/HSPA network with a node B and emulated RNC, SGSN, GGSN and HLR components; a deployment of a Wireless Mesh Backhaul testbed with Mobile Edge Computing (MEC) capabilities deployed in the CTTC building or an all-wireless network of femtocells (NoF) connected to a UMTS core network and using WLAN technology as the local backhaul inside the network of femtocells.
General Features
The EXTREME Testbed® provides:
- fast adoption and testing of new emerging technologies in a close-to-real environment.
- a substantial reduction of time from scenario conception to start of the evaluation phase.
- a generic framework to ease the realization and analysis of performance measurements.
- an abstraction of the underlying low-level configuration, so that users focus on concepts rather than scenario configuration details.
with an up-to-date technology especially-suited for wireless scenarios.
It is intended for
- experimental validation of theoretical results.
- rapid and seamless adoption of new emerging wireless technologies.
- implementation of different architectures through a reduced configuration time.
- full end-to-end monitoring of the experimental testbed.
- integration of commercial networking and traffic analysis equipment for interoperability testing.
