| Abstract: | The expressway real-time digital monitoring system based on MSTP is discussed in this paper. New generation MSTP supports shared Ethernet ring, and it can enhance data transmission efficiency. A comparison between SDH and MSTP on the efficiency of bandwidth usage for digital video transmission is made first, then, the latency of digital video transmission over MSTP is analyzed. The MSTP access methods for variety video transmitting devices are also discussed at the end of the article. The result indicated that MSTP has high efficiency bandwidth usage and little latency characteristic, it satisfies the demands of expressway networked monitoring extremely. |
