消息

1969年，美国UCLA（Univ.of California，Los Angeles）以L.Kleinrock教授为中心，该校和附近的3个机构（UCSB（Univ.of California，Santa Barbara），SRI（Standaford Research Instute），在将U of U（Univ.of Utah）的计算机各连接一台的网络中。以这4台主机为源头的互联网，在2016年1月形成一个主机连接量超过10亿台的网络。当然，计算机和通信技术的发展对此做出了巨大贡献。然而，如此大规模系统的成功构建，不能忽略理论上合理的系统设计方法。Kleinrock教授在开创网络之前，曾在提交给MIT（Massachusetts Institute of Technology）的学位论文中指出了这一重要性。1975年出版的学术著作《Queueing Theory》第1卷和第2卷，成为后来互联网发展的基础理论。这本著作的日语译本为《排队理论》。即使到现在，它仍然是一本基本教科书，不仅适合网络从业人员，还适合对应用概率论感兴趣的研究人员。我在读研究生时邂逅了这本书，激发了我对基于数学的理论与网络之类真实系统之间的接点即理论与实践相结合领域的兴趣。从那时起，我一直从事与信息系统数学模型和性能评估有关的研究。

希望进入本校的各位，能够在大学院掌握今后50年受益并且能支撑自身职业生涯的学习能力与研究能力，深度参与引领下一代的核心技术。
