将网络功能分解为更小的子集简化了实现并导致了开放标准。尽管如此，在诸如移动无线ATM这样资源稀缺的应用程序中，协议栈必须不影响性能。协议栈的各层逐渐增强并增加了所支持服务的可靠性。随着附加的新函数，高层经常实现误差控制算法来克服从低层逃脱的残余误差。如果大量的残留错误逃逸，就像在移动无线ATM环境中可能发生的那样，那么频繁的重传或重新初始化更高层的协议实体可能会导致吞吐量的严重损失。在本文中，我们使用显式模型来解释两层之间的交互，研究跨越协议栈两层的错误的后果。
The decomposition of networking functions into smaller subsets simplifies implementation and leads to open standards. Nonetheless, in applications such as mobile wireless ATM, where resources are scarce, protocol stacks must not compromise on performance. The layers of a protocol stack progressively enhance and add reliability to the supported services. Along with additional new functions, the higher layers frequently implement error control algorithms to overcome residual errors that escape the lower layers. If relatively large numbers of residual errors escape, as is likely in the mobile wireless ATM environment, then frequent retransmissions or reinitialization of the higher layer protocol entity could result in drastic loss of throughput. In this paper we examine the consequences of errors spanning two layers of a protocol stack using an explicit model to account for the interaction between two layers.
