C-MUX2网管信息通道重构方案研究

Research of C-MUX2 Network Management Information Channel Reconfiguration Scheme

为解决原有C-MUX2网管通道因配套的马可尼SDH设备改造而中断的问题,通过对网管信息传输机制的深入分析,摒弃了原有利用SDH段开销保留字节传输网管信息的复杂方式,研究新的利用业务通道传输网管信息的方式,提出了2种解决方案,并比较其优缺点,选择简明、可靠的方式,完成了对PCM网管通信的重构。在智能电网建设对通信网络管理提出更高要求的背景下,对PCM网管通信传输问题的解决提供了一种有益的参考思路。

In order to solve the interruption issue of the original C-MUX2 network channel due to the upgrading of its matching Marconi SDH equipment, this paper deeply analyzes the transmission mechanism of network management information, discards the existing complex way of transmitting network management information through the reserved bytes in SDH SOH, studies a new way of transmitting network management information through business channels and gives two kinds of solutions and their comparison. Further, a simple and reliable way is selected to reconstruct the PCM network management communication. Under the background of the higher requirements on communication network management by the construction of smart grid, this paper provides a good reference for PCM network management information transmission.
