Capgemini MeSH - Messaging Framework
• Abstracts away WSE or WCF
• Simple interface
• Chained together
• Composable at Deploy Time (.config)
• Top of the 'CDAF Stack' for Services
Capgemini MeSH – Chain of Responsibility
• Implemented with the 'Chain of Responsibility' pattern
• Definition (GoF) –
• 'Avoid coupling the sender of a request to its receiver by giving
more than one object a chance to handle the request. Chain the
receiving objects and pass the request along the chain until an
object handles it.'

Capgemini MeSH – Pipes and Filters
• Based on the Pipes and Filters pattern
• See 'Enterprise Integration Patterns'
• By Gregor Hohpe & Bobby Woolf - Addison Wesley
• Definition –
• 'Use the Pipes and Filters architectural style to divide a larger
processing task into a sequence of smaller, independent
processing steps (Filters) that are connected by channels
(Pipes).'
