Quality of Service (QoS) has become increasingly important in metropolitan area networks and even more important in open access networks where service providers should be able to offer their services on equal terms. This paper present a network architecture with a hierarchical star-mesh topology, which provides the scalability and redundancy required for future open access networks. To support QoS a combination of Ethernet and Multiprotocol Label Switching (MPLS) is proposed. With the use of a switch, on the highest level, based on micro electromechanical system (MEMS) technology this proposed architecture could reach aggregated bitrates above 10 Tbit/s. IPSec is proposed for solving the security issues in the network that emerges when different service providers share the same network and future applications are developed.
