Obiettivo WP3

• Il WP3 allinterno del progetto MAIS ha come
  obiettivo ultimo lo studio di una Reflexive
  architectures for context-aware services e
  limplementazione di un prototipo di
  questultima.
• Obiettivo a breve definire entro novembre 2003
  un modello architetturale riflessivo relativo al
  livello logico e focalizzato sulle astrazioni
  significative ai fini della osservazione e del
  controllo di aspetti relativi a QoS.

Lo stato dellarte (1)

• Allo stato attuale sono state svolte le seguenti
  attività
• analisi delle architetture software e degli
  approcci riflessivi computazionali,
  architetturali e temporali
• analisi dei requisiti per la modellizzazione di
  device in una architettura di un sistema adattivo
  multicanale
• prototipazione di unapplicazione Java per la
  creazione, la modifica e la gestione di un
  singolo device (pc)
• analisi del modello CIM (Common Information
  Model) del DMTF (Distributed Management Task
  Force), le cui informazioni sono disponibili al
  seguente indirizzo www.dmtf.org
• creazione di un modello UML per la
  rappresentazione di device, estrapolato dal CIM
  citato al punto precedente

Lo stato dellarte (2)

• Analisi dello stato dellarte di
• Web service reliability
• Proposta oraclesun\ibm
• Solo message persistence
• Quality object di BBN technologies
• Contratti Compile time reflection
• Design protocolli di replicazione in architetture
  a 3 livelli
