本系列讲座系统介绍现代电信中主要交换技术的基本原理和特点。从技术发展的角度对逐项交换技术展开分析,并着重于不同交换技术之间的有机联系。考虑到知识的系统性本讲座将包括:电路交换、分组交换、帧中继、ATM交换、IP交换、标记交换、多协议标记交换(MPLS)、光交换等几个方面的内容。但是对于电路交换、分组交换等较成熟的技术只做概括性讲述,而对于ATM、IP交换、标记交换、MPLS、光交换等交换技术将给以较充分的讨论。
This series of lectures introduces the basic principles and features of the major switching technologies in modern telecommunications. From the perspective of technology development, it analyzes the technology of item-by-item exchange and focuses on the organic connection between different exchange technologies. Taking into account the systematic knowledge of this seminar will include: circuit switching, packet switching, frame relay, ATM switching, IP exchange, label switching, multi-protocol label switching (MPLS), optical switching, and several other aspects. However, the more mature technologies such as circuit switching and packet switching are only briefly described, and the exchange technologies such as ATM, IP exchange, mark exchange, MPLS and optical exchange will be fully discussed.
