Color Explanation: This proposal is based on the nested service and the information model Composite / Atomic Service, all the colored parts excluding black ones are new added changes to the basic model. Blue parts excepts class "ServiceProfile" and "SliceProfile" are for the filter fuctionality, pink parts are for service configuration functionality, purple and green are needed for filter function in instance model, but for two different functions respectively. Detailed information please go through the tables below.
