EN The paper presents the results on experimental CARMNET system deployment in metropolitan wireless networks. The system consists of several components among which the main role is played by CARMNET Loadable Linux Module. This module is aimed at providing the delay-aware resource allocation based on Delay-Aware Network Utility Maximisation System (DANUMS). The DANUMS-specific communication, including the reports on queue levels and delays, is realized by means of the Optimized Link State Routing (OLSR) protocol extension. By assuring theoretically-grounded high throughput effectiveness (based on max-weight scheduling) and carrier-grade network reliability, the solution provides the means for enhancement of the Internet access technology for commercial Internet Service Providers. At the same time, the system is aimed at supporting the development of purely-open, society-based, noncommercially operated wireless networks that have recently gained popularity in several European agglomerations. In this paper, we describe the CARMNET application scenarios and results from first experimental deployment of the system in existing networks.
