Abstract
A network monitor monitors traffic on a dedicated data network passively. The data network connects network controllers which control associated network elements of an automatically switched optical transport network. The network controllers regularly advertise their locally stored network topology and status information using a predefined protocol. The monitor filters protocol frames of this predefined protocol type and extracts therefrom information about the topology and status of the transport network and displays these information graphically to a user.
