摘要
IP over ATM的一个问题是由多个封装和ATM单元填充引起的带宽效率低下，特别是对于短数据和中等数据。ATM捷径是为IP流建立的ATM虚拟电路连接，它允许IP数据包直接由底层ATM网络路由。本文首先讨论了如何采用这种方法去除具有ATM捷径的IP流的IP数据包的IP封装，然后通过简单的分析表明，当它与AAL2复用联合使用时，可以提高带宽效率，特别是对于短数据和中等数据。
Flexible IP encapsulation for IP over ATM with ATM shortcuts
One problem for IP over ATM is the bandwidth inefficiency caused by multiple encapsulations and the ATM cell padding, especially for short and moderate data. An ATM shortcut, an ATM virtual circuit connection established for an IP flow, can allow IP packets to be routed directly by the underlaid ATM network. In this paper, we first discuss how to adopt this approach to remove the IP encapsulation for IP packets belonging to an IP flow having an ATM shortcut, then show, through simple analysis, that this effort can improve the bandwidth efficiency especially for short and moderate data when it is used jointly with the AAL2 multiplexing.
