A specialized communication network is designed based on satellite communications link,and it has shortcoming of narrow bandwidth and large transmission delay. The network is required to monitor multiple remote Satcom stations,but traditional ground-based network monitoring protocol is unsuitable for satellite channel because it is designed based on wired network,and occupies a large bandwidth. According to the need of equipment real-time monitoring in narrow-band satellite channel situation,the transfer protocol for monitoring equipment information is designed,which includes transmission data,transmission time,equipment identification code etc. The data structure of parameter reported is optimized through making a distinction process between the"0","1"parameter and other normal parameters,thus improving the bandwidth utilization ratio effectively. Actual results prove that after using this protocol,bandwidth utilization ratio has increased by about 40%,the transmission of monitoring information is real-time and accurate,thus providing convenience for trouble shooting and problem analysis of equipment and improving system operation and management capabilities.
