In this paper we introduce a congestion control method suitable for carrier Ethernet/metro Ethernet networks. Ethernet is considered to replace ATM as provider access aggregation network technology due to its cost efficiency, but it still lacks many necessary features to provide quality of service (QoS) as required from carrier-grade networks. This(More)
The network infrastructure within the Access and Aggregation domains of provider networks are subject to significant changes, both in technology as well as in their business model. Recently, a number of research initiatives, most notably MUSE and PlaNetS, have promoted the development of a unified broadband access and aggregation network platform. It is(More)
We identify deployment trends and primary tasks a future DSL access multiplexer (DSLAM) has to offer. We reveal two corner cases: IP-based (high-end) versus Ethernet-based (cost-optimized) access networks. We derive the need for flexible hardware platforms to support fast customization and adaptation to new protocol standards. To accomplish efficiency and(More)
