I.2 Implementation flows of resource guarantee based on network awareness

Figure I.2 – Implementation flows of resource guarantee based on network awareness

Figure I.2 shows the implementation flows of resource guarantee based on network awareness:
– 1: The S-NICE orchestration functions send resource request for special service to the S-NICE
controller functions;
– 2: The S-NICE infrastructure functions send real time traffic information (such as network
congestions) to the S-NICE controller functions;
– 3: According to the resource request, the network awareness traffic information, the S-NICE
controller functions decide if one or several resource guarantee policy rules are matched;

– 4: If yes, the S-NICE controller functions translate the policy rules into instruction requests and send
them to the S-NICE infrastructure functions;
– 5: The S-NICE infrastructure functions execute all the related instructions;

– 6-7: After all instructions have been executed, the confirmation message is sent back to the S-NICE
orchestration functions.
