NITLAB provides highly flexible and programmable platforms that span across the networking, cloud, and edge computing domains. These infrastructures are designed to support the full lifecycle of digital experimentation — from simulation and prototyping to real-world deployment and validation. Researchers can experiment with virtualized services, programmable network functions, and data-driven applications across distributed environments. Our testbeds enable repeatable experimentation and integration with open-source tools, supporting both foundational research and industrial validation efforts. This environment empowers innovation in areas such as service orchestration, cybersecurity, network automation, and federated experimentation.
