I.1 Implementation flows of on-demand provision

Figure I.1 – Implementation flows of on-demand provision

Figure I.1 shows the implementation flows of on-demand provision:

– 1: The application sends an on-demand provision request to the S-NICE orchestration functions;
– 2: According to the provision request, the S-NICE orchestration functions generate service requests;
– 3: The S-NICE orchestration functions send service requests to the S-NICE controller functions;
– 4: The S-NICE controller functions create policy rules based on the service request and the traffic
optimization result;
– 5: The S-NICE controller functions translate the policy rules into instruction requests and send them
to the S-NICE infrastructure functions;
– 6: The S-NICE infrastructure functions execute all the instructions;
– 7-9: After all instructions have been executed, the confirmation message is sent back to the
application.
