The worst case cell arrival patterns that conform to the GCRA in ATM networks

The asynchronous transfer mode (ATM) is well known technology for implementing broadband integrated services digital networks. A major issue in ATM technology is traffic control. We introduce the concepts of conservative cell loss ratio (CLR) estimation and worst case cell arrival patterns, and apply them to cell arrival patterns that conform to the generic cell rate algorithm (GCRA). We define new sets of cell arrival patterns which contain the worst case cell arrival patterns for compliant cell arrival patterns. Based on these sets, we propose a connection admission control method. A numerical example demonstrates its effectiveness
