Recently, because of the expansion of TCP/IP networks, the evaluation of IP
networks is being considered as a major task for network operators and adm
inistrators. As a result, many IP evaluation tools have appeared, but almos
t all of them can only be applied to a limited purpose. The authors have al
ready developed an IP evaluation tool, called KITS (KDD Internet Test Syste
m) [1] that can generate flexible load traffic. Based on KITS, the authors
have now developed a new IP measurement tool. This paper describes the flex
ible and general IP evaluation tool, STAGE (Simulated Traffic Analyzer/gene
rator for General Evaluation).
