Resuable Network Management Components Abstract: Every equipment manufacturer requires a solution for the element management of the equipment. Traditionally, an EMS is built custom to the requirements of the network elements that it has to manage. When the equipment manufacturer builds a new product line or upgrades the existing one, the cost to port / re-engineer the existing EMS becomes a major hurdle for the change.Reusable NM Components ( RNMC) provides an easy solution to this problem.
