Appendix I

Mapping of inter-cloud computing functional requirements and functions
(This appendix does not form an integral part of this Recommendation.)

This appendix aims to describe the mapping of inter-cloud computing functional requirements specified in
[ITU-T Y.3511] and inter-cloud functions in clause 7 of this Recommendation.

and inter-cloud functions

Inter-cloud functions in this
Functional requirements specified in [ITU-T Y.3511]
Recommendation
– 7.3.1 Peer CSP management
The SLA and policy negotiation capability is required to
9.1 SLA and be aware of the SLA information related to the QoS and – 7.2.4 Service policy management
policy – 7.2.6 Service level management
performance aspects of the CSPs involved in the inter-
negotiation – 7.2.8 Peer service management
cloud using standard formats.
– 7.3.7 Inter-cloud capabilities adaptation
Allow describing and expressing of the resource
– 7.2.8 Peer service management
9.2 resource information (e.g., resource type, configuration and
– 7.3.2 Inter-cloud service negotiation
monitoring status) in a standard manner in order to be able to
monitor these resources across multiple CSPs. – 7.3.7 Inter-cloud capabilities adaptation
Allow updating of the resource information across – 7.2.8 Peer service management
9.2 resource multiple CSPs in synchronization with the events (e.g., – 7.2.3 Monitoring and reporting
monitoring
reserve or release of resources) involving the CSPs. – 7.3.7 Inter-cloud capabilities adaptation
– 7.2.3 Monitoring and reporting
Allow periodically, or on a request basis, collecting of
9.2 resource information about the usage and performance status of – 7.2.8 Peer service management
monitoring – 7.3.2 Inter-cloud service negotiation
the resources of multiple CSPs.
– 7.3.7 Inter-cloud capabilities adaptation
Allow periodically, or on a request basis, collecting of – 7.2.3 Monitoring and reporting
9.2 resource
information about the resource availability (e.g., dead or – 7.2.8 Peer service management
monitoring
alive status of machines) of multiple CSPs. – 7.3.7 Inter-cloud capabilities adaptation
– 7.2.3 Monitoring and reporting
9.2 resource Allow exchange of monitoring information in commonly
– 7.2.8 Peer service management
monitoring defined ways across multiple CSPs.
– 7.3.7 Inter-cloud capabilities adaptation
The resource performance estimation and selection
capability deals with the selection of resources from the
9.3 resource candidate resources that have already been reserved in – 7.2.8 Peer service management
performance peer CSPs. This capability estimates the achievable – 7.3.4 Inter-cloud service selection
estimation
performance of available reserved resources and assists – 7.3.7 Inter-cloud capabilities adaptation
and selection
the CSP in the selection of resources to be effectively
used.
9.4 resource Allow finding of available resources in the peer CSPs
discovery based on different priorities. – 7.3.2 Inter-cloud service negotiation
and Allow reservation of available resources in the peer CSPs – 7.3.7 Inter-cloud capabilities adaptation
reservation on the basis of different priorities
9.4 resource
discovery Enable discovery of resources available in the peer CSPs. – 7.3.3 Inter-cloud service discovery
and – 7.3.7 Inter-cloud capabilities adaptation
reservation
