摘要
OTN中可通过光监控通道(OSC)、电监控通道(ESC)以及外部DCN来组织数据通信网络用于网络的运行、管理、维护和保护(OAM&P),其中OSC方式应用较多。随着OTN设备的广泛应用部署,基于OTN帧中通用通信通道(GCC)字节的ESC也成为网络管理通道的主要手段。详细介绍了基于OTN帧结构中GCC的ESC技术,与OSC技术进行了分析对比,并给出了OTN中基于GCC的ESC技术的技术要求和不同应用场景的建议。
The techniques of optical supervisory channel, electronical supervisory channel and external DCN are mainly used for the net-work OAM in optical transport network, and OSC technique nowadays is mostly utilized. As the wide deployment o optical transport network equipments, ESC technique is also used more. ESC based on GCC of OUT frame was introduced firstly, after the comparison between ESC and OSC techniques, the technique specification and application scenarios of ESC based on GCC in optical transport network were analyzed and suggested.
