在ATM主干上和各种VBR流量模式下，TCP通过ABR的性能
Performance of TCP over ABR on ATM backbone and with various VBR traffic patterns
摘要：
我们在两个方向上扩展了我们以前的研究TCP ABR的缓冲区要求。首先，我们研究了ATM骨干网中TCP在ABR上的性能。在主干上，TCP队列位于边缘路由器，而不在ATM网络内部。路由器要求缓冲区等于参与TCP连接的接收器窗口大小之和。其次，我们介绍了各种模式的VBR背景流量。VBR背景在ABR容量中引入方差，并且TCP业务在ABR需求中引入方差。一些简单的切换方案无法跟上高度变化的需求和高度变化的ABR容量的组合效果。我们提出了我们的经验，完善ERICA+开关方案，以处理这些条件。
英文摘要：
We extend our earlier studies of buffer requirements of TCP over ABR in two directions. First, we study the performance of TCP over ABR in an ATM backbone. On the backbone, the TCP queues are at the edge router and not inside the ATM network. The router requires buffer equal to the sum of the receiver window sizes of the participating TCP connections. Second, we introduce various patterns of VBR background traffic. The VBR background introduces variance in the ABR capacity and the TCP traffic introduces variance in the ABR demand. Some simple switch schemes are unable to keep up with the combined effect of highly varying demands and highly varying ABR capacity. We present our experiences with refining the ERICA+ switch scheme to handle these conditions.
