SPACEMAN: A SpaceWire network management tool

The recently developed SpaceWire Plug-and-Play protocol offers a number of possibilities in network management, including standard methods of discovery and verification. This paper presents a network management prototype tool which uses the Plug-and-Play mechanisms to produce a topology and configuration database with an XML representation of a SpaceWire network, using an XML profile that is currently under definition by ESA. That repository can then be used to produce a graphical visualization of the network. The mechanisms which make network discovery possible can also be used to perform active network management, where the network engineer modifies the network topology and node configuration beginning with the graphical network view. The tool is currently being developed in the SPACEMAN project. The architecture and implementation details are presented, as well as validation and demonstration setup.
