EU tender results 40% costs down for variable part of electricity of IDM
- 01 Jan 2017
Because of IDM network consists of 167 active nodes includes 42 backbone containers, 93active distribution cabinets and 32 NGA cabinets), the network consumes much of electricity. In containers, two air conditioners maintain adequate temperature and humidity, DWDM equipment consumes max 3KW of electricity, a router consumes max 16.8 KW. In addition, each 93 active distribution cabinets also requires electricity to operate correctly which has 8.4KW router in the cabinet and 32 NGA cabinets also require electricity. Therefore, reducing the cost of electricity is a key part of the cost management in IDM operation.
Invisible WDB in the IDM network are getting visible in NOC
- 01 Mar 2017
The IDM network, which has total 3,680 km of fiber optic network, 42 backbone nodes, and 308 distribution nodes, had been suffered from no visibility of passive only distribution links and nodes(refers to WDB). Even the cable was damaged by third party, the network operation center could not monitor due to the limited architecture of the IDM network. In usual, active nodes could be monitored by checking connection status in various methods which include PING at every period. However, over the half of the distribution nodes of the IDM were passive only node which means there is no active devices to react PING, even no electricity. Therefore, the operation center could not monitor the status of the node and relations.
