In general, the term Customer Network Management (CNM) means to provide a controlled access to a service provider's management information. This access allows customers to retrieve management information which has been preprocessed according to their needs and to change the service configuration in a predefined manner.

The tool shows the network topology using a set of hierarchical topology maps. The maps contain network nodes (routers or switches) and links including status information and metrics. In the prototypical version the link utilization is the first metric which is displayed since this metric has also been available in many networks and is retrievabel by perfSONAR Round Robin Database MAs. It is not only possible to see the current situation in the network, but also to go back to a situation in the past which is enabled by a time navigation function. In addition, graphs can be opened to show the course of metrics over time using statistics on a daily, weekly, or monthly basis.

The CNM tool has the capability to customize views and to limit the access to metrics. This is done using its authentication mechanism. This functionality is useful for projects which would like to use the CNM since it can offer a view onto the network connecting the partners. In addition, this mechanisms supports storing user preferences (e.g. preferred maps, preferred metrics).

PerfsonarUI is designed and implemented as an open source, easy to use and yet powerful stand alone graphical user interface client capable of querying a range of perfSONAR services deployed around the world (currently 18 interface utilization Measurement Archives and one IP Performance Metrics Measurement Archive). The primary target user groups for perfsonarUI include NOC and PERT staff, as well as projects with demanding network performance requirements. End-users with some basic technical background also are supposed to master the tool quite easily.

The training is also available from http://cbt.geant.net/repository/gn3/perfsonarui/perfsonarui.htm.

The main goal is to:

• Implement a web-based application that enables its user, for the given specific IP path (most often the output of the traceroute command) to view the statistics for all the interfaces along the path using perfSONAR Measurement Archives (MA)
• Give the user a tool to provide the graphical representation of the path over the geographical map using geographical coordinates of the interfaces, when available.

This tool is still under development; a link will be available as soon as the tool is released.
