Page 425 - Cloud computing: From paradigm to operation

Framework and requirements for cloud computing 1

• Carrier Ethernet Services for Cloud Use Cases:

– includes both single and multiple Ethernet cloud carrier domain cases;
– Part1: for Cloud Provider Interconnect (CP to CP);
– Part2: for Enterprise Access to CP.
• Carrier Ethernet Services for Cloud Management Interface Profile:
– identify relevant Protocol Neutral MEF 7.x objects (and attributes);
– operational use cases and information requirements for CP to ECC management interface;

– focus on reconfiguration of specific service attributes (e.g., CIR);
– Phase 1 approach: changes to service attributes occur only when EVC/OVC is inactive or during
a maintenance interval;

– explore scheduled reconfiguration and configuration durations;
– provide interface operational requirements: number of changes allowed over time (how long
change should last); lead time for request fulfilment;

– describe SLSs for management interactions (performance metrics).
