Abstract

In this paper, we propose ATM switch architecture including ALL type 2 switch which can efficiently transmit low-bit rate data, even if the network has many endpoints. We simulate the architecture of ATM switch fabric that is modeled in computer program and analyze the performance according to offered loads. ATM switch proposed in this paper can support cell switching for all types of m cells which consist of ALL type 1. ALL type 2, ALL type 3/4 and ALL type 5 cells. We propose two switch fabric methods; One supports the ALL type 2 cell processing per input port, the other global ALL type 2 cell processing for every input port. The simulation results show that the latter is superior to the former. But the former has a merit for easy implementation and extensibility. In this paper, the AAL Type 2 switch module which adapts the former method is designed using VHDL language and implemented in FPGA chip. The designed AAL Type 2 switch module operates at 52MHz. The proposed ATM switch fabric is widely applicable to mobile communication, narrow band services over ATM network and wireless ATM as well as general ATM switching fabric.
