Tenth SpaceWire Working Group meeting, ESA/ESTEC

20^th and 21^st of February 2008

Room Einstein

Scope

The meeting focused on two main topics:

· The first one dealt with real time aspects and related services and protocols for SpaceWire networks, enabling Command and Control applications using SpW. On the basis of quality of service requirements and definition, constraints applicable to SpW networks when implementing applications requiring real time behaviour have been discussed. This includes the mapping of CCSDS services implying such requirements. (Convenors: Ph. Armbruster, ESA/ESTEC and S. Parkes, UoD)

· The second main focus was SpaceFibre (Convenor: M. Suess, ESA/ESTEC)

Other topics:

· SpW Test, Verification and “Certification” (Convenor Y. Sheynin, UoStPg)

· SpW Backplanes (Convenor M.Nomachi, UoO)

· SpW and Plug and Play (Convenor G.Rakow, NASA/GSFC)

· SpW Deployment and Handbook (Convenor, B. Cook, 4Links)

· SpaceWire International Conference 2008 – Osaka/Nara 4-5-6 of November 2008 - (M. Nomachi)
