86. The structure of background network

87. The structure of background network(1/3) MP NT Server TCP/IP protocol NT Client.. NT Client 。。。 router DDN PSTN/PSPDN MP

88. The structure of background network(2/3) The network contain 3 types of nodes: Foreground active/standby MP Background servers(server) Background maintenance terminal(clients) MP (foreground ) connects with background by the Ethernet. It uses the HUB to connect each other. The communication protocol is TCP/IP. The operation system of Sever and Client is WINDOWS NT

89. The structure of background network(3/3) Each MP and the computer in background have a IP address respectively. The arrangement is as follows: 1~128 identify the active/standby Mps of the 64 modules(MP nodes) 129~133are background NT Server nodes 134~187 are background Client nodes 254 is for the specific alarm panel.
