With increasing demands of bandwidth and quantity on test and control network, it's necessary to find more efficient transmit ways. This article introduces construction of test and control network based on IP over SDH firstly. By analysis of transmit structure and protocol stack, several keys of information processing are pointed. After processing, the concerned information on the test and control network can be identified and picked up from the SDH frame directly. Furthermore a system module designed with FPGA is proposed.
