自动交换光网络技术及其标准状况

Automatically switched optical network technology and standard status

针对因特网业务迅猛发展及新型业务不断涌现的现状,为了满足用户多业务、高带宽的通信需求,自动交换光网络(ASON)应运而生,且受到学术界和产业界的广泛关注。对ASON的产业化发展现状与标准需求进行了相应的分析,介绍了ASON标准研究状况,对3个国际标准化组织ITU-T(国际电信联盟远程通信标准化组织)、IETF(互联网工程任务组)、OIF(光互联网论坛)进行横向比对,同时对现有的国内ASON标准进行阐述之后,提出了针对我国ASON技术标准及其产业推进的切实有效的相关建议。

According to the status of rapidly development of Internet services and the emergence of the new services, automatically switched optical network （ASON） emerges at the right moment in order to satisfy the customers＇multiservices and high bit rate communication requirements, and it has attracted intensive attention from the academic and industrial circles. This paper firstly analysis the industrialization status and standardization requirements of the ASON. Then the existing standards of ASON from ITU-T, IETF, and OIF are introduced. Finally, suggestions for the standardization and industrialization of ASON in China are given.
