The description below is a first idea to be +elaborated and discussed further. + +A NS will have defined, as part of the descriptor, different ordered scale +steps, starting from number 1. For each step different groups of VNFs and VLDs +will be required. + +For simplicity, the feature will assume that the trigger will be manual by +the network operator, using the UI. The trigger will specify to which scale step +the NS will move. + +The action will reach the SO, which will identify the incremental additions +required in the RO and in the VCA. First, the actions to be done in the RO will be +executed, and later, the ones in the VCA. + +Rollback mechanisms should be implemented E2E accross mechanisms. + +Regarding the interaction between SO and RO, the following mechanism is proposed: +- The SO will turn scaling-up of a single NS events into new RO Network Scenarios +and will orchestrate them in RO. +- The SO will turn scaling-down events into Network Scenario terminations in RO. +- The SO will keep control of the different RO Network Scenarios that belong to +a NS in the SO. + +## Demo or definition of done ## +N/A + +
