异步转移模式（ＡＴＭ）在局域网技术方面的成功，是通过建立与现有规程和应用相兼容的ＡＴＭ局域网，开展类似于局域网的服务，消除当前建立在共享介质基础上的局域网可能成为急剧增长的业务量的“瓶颈”问题。在ＡＴＭ局域网上执行网间协议（ＩＰ），可以采用两种方案：一种ＡＴＭ按ＩＥＥＥ８０２逻辑链路控制子层（ＬＬＣ）下的介质访问控制子层（ＭＡＣ）构造，建立类似于广播方式的介质共享的传统式局域网，即局域网仿真。另一种ＡＴＭ按照独立的数据链路层规程构造，可直接在ＡＴＭ上执行ＩＰ及其它网络层协议。
Asynchronous Transfer Mode (ATM) has succeeded in LAN technology by launching LAN-like services that are compatible with existing protocols and applications and eliminating the current burgeoning LAN based on shared media Business “bottleneck” problem. There are two schemes for implementing an internetworking protocol (IP) over an ATM local area network: one ATM is constructed in a media access control sublayer (MAC) under the IEEE 802 logical link control sublayer (LLC) Media sharing traditional LAN, LAN simulation. The other type of ATM, built on a standalone data link layer protocol, performs IP and other network layer protocols directly on the ATM.
