| Summary: | 碩士 === 國立臺灣大學 === 電機工程學系 === 85 === The ATM is accepted as the transport technique for the B-ISDN
and becomes one of the key techniques of current high speed
network. How to design and implement a high performance and low
cost ATM device is becoming more important for rapid development
of network services. In this thesis, we introduce a chip set
based architecture of ATM switch which has the advantages of
system expandability and controllability. An 16x16 155Mbpsports
switch controller has been implemented and its shows the
potentialof further development. A buffer management mechanism
which combines threepacket discarding schemems, including PPD,
EPD and APPD, is implementedin the APPD switch controller. In
addition, implementation of some necessaryfunctions of an ATM
switch with an external processor are also introduced in this
thesis.
