| Summary: | 碩士 === 大同工學院 === 資訊工程學系 === 84 === With the growth of multimedia service, the bandwidth of
traditional networks can not be satisfied. However, the ATM
network is the optimal solution for resolving this problem
nowadays. Therefore, the design of ATM service
environment to provide the multimedia communications and enhance
the B-ISDN services is one of the main objectives in current
computer and communication industries. But, the ATM network is
based on cell switching technique quite different to the
packet switching of the traditional networks. Thus, the
interconnection of these two kinds of networks is difficult. To
unimpede in information transmission, the study of
interconnection is an important issue.
PC-based transparent unit for interconnecting the cell-based
networks using ATM technology and frame-based networks, such
as LANs, is designed in our TTIT-ATM testbed and reported
here. The main essential of designed InterWorking
Unit (IWU) is doing its best to achieve a seamless integration
by using the address resolution protocol and connection
management. The key techniques being developed as well as the
configuration and QoS analysis beingundertaken are explored in
this article. Moreover, the implementation issue and
conformance testing are also discussed in the theme. We believe
that the deliverable unit is a very economic and efficient
solution for existing LANs which make the evolution to cell-
based networks while the IWU is still a high-price product in
the network market.
