SpW Network Management

SpW Network Management

The SpaceWire protocol stack clearly specifies protocols layering from the Physical up to the Network layer. Layers over the basic SpaceWire protocol stack with a variety of Transport layer protocols, scheduling and FDIR services, connection with the Application layer do not have consistent specification. The problem of layering higher layer protocols over SpaceWire is considered.

Presentation

SpW Network Management

A number of SpaceWire network discovery scenarios have been studied in the SPACEMAN project. In the presentation the main functionalities of the SPACEMAN network management tool are introduced, then examples of network topologies are shown, both acyclic and cyclic (with cycles or loops). The algorithms used for determining the identity of the devices and discovering the network are...
