Paper Abstract

Third Generation Wireless Systems are rapidly moving towards the development after the successful completion of prototypes, demonstrating the core functionality. CDMA-2000 is a third generation mobile wireless system on which integrated voice and data applications will be supported. In an IS-634 wireless access network, the Selection Distribution Unit (SDU) performs the frame selection and distribution of traffic frames carrying voice, data, and signaling between a mobile station and the wireless network. In this paper we present architecture of a SDU based on a network processor and analyze the performance of CDMA-2000 voice traffic on it. We also include the performance results obtained on a general-purpose processor based SDU. The performance results indicate that a network processor based SDU has significant better throughput performance over the SDU unit equipped with general-purpose processors.
