Modular Reference Implementation of an IP-DSLAM

We describe a modular reference implementation of an IPbased DSL access multiplexer (DSLAM). We identify deployment trends and primary tasks a future DSLAM has to offer. The implementation is representative of applications in access networks and indicative of real-world performance. To accomplish these goals our tool flow CRACC takes a modular application description and generates code for embedded processors that can easily be ported to different platforms. The derived implementation serves as a benchmark for DSLAM systems. It therefore allows the comparison of different architectures, partitioning, and mapping decisions. In addition to a full system benchmark, our reference implementation is a functionally correct realization with defined evaluation environment, traffic sources, and load scenarios. We present evaluation results of our DSLAM implementation on several embedded processors.
