Management
System
Deployment
The TransNav management system software package contains server applications,
client workstation applications, and agent applications that reside on the node.
Figure 6 Management System Deployment
Each TransNav management system supports up to eight servers; one server is
designated as the Primary server, the remaining optional servers are designated as
Secondary servers. The Primary server actively manages the network. The Secondary
servers passively view the network but cannot perform any management operations
that would change the state of the network. Any Secondary server can be promoted to
the Primary server role in case of failure or maintenance. The switch in server roles
requires some degree of user intervention.
The server applications communicate with the nodes and maintain a database of
topology, configuration, fault, and performance data for all nodes. The client
workstation application provides the user interface for managing the network (GUI or
CLI). The agent application resides on the node control card and maintains a persistent
database of management information for the node. It also controls the flow of
information between the management server and the node itself.
TransNav
Network
Management
In addition to the management system applications, the TransNav management system
uses the following Traverse software components:
Intelligent Control Plane
An Intelligent Control Plane is a logical set of connections between TransNav-managed
network elements through which those network elements exchange control and
management information. This control and management information can be carried
either in-band or out-of-band.

description of IP quality of service routing protocol.

proxy address resolution protocol.
