Table III.1 – Alignment analysis with functional requirements in [ITU-T Y.3513]
Functional requirements in [ITU-T Y.3513] Test objects in this Recommendation
36 7.3.1 Network – It is recommended that the IaaS CSP – 9.1 Interoperability testing of
policy provides network policy migration along network policy migration between
migration with virtual machine migration. In this case, the CSC and CSP
the network policy of the migrated virtual
machine is the same as before the migration.
37 7.3.2 Network – It is recommended that the IaaS CSP – 9.2 Interoperability testing of
QoS provides operation handling mechanisms network QoS between the CSC and
related to the network quality of service CSP
(QoS), such as bandwidth limit, bandwidth
reservation, traffic shaping, traffic
classification, congestion avoidance, at port
level, device level and network level.
38 7.3.3 IP – It is recommended that the IaaS CSP – 9.6 Interoperability testing of IP
Address provides IP address reservation. address reservation between the
CSC and CSP
39 – It is required that the IaaS CSP allows the – 9.5 Interoperability testing of IP
CSC to apply, bind, unbind, query, release an address allocation between the CSC
IP address to processing resources or storage and CSP
resources.
40 – It is recommended that the IaaS CSP allows – 9.5 Interoperability testing of IP
the CSC to allocate IP addresses to address allocation between the CSC
provisioned processing resources or storage and CSP
resources with a dynamic or static method.
41 – The IaaS CSP can optionally provide network – 9.3 Interoperability testing of
address translation (NAT). network address translation
between the CSC and CSP
42 7.3.4 Network – It is required that the IaaS CSP provides the – 9.4 Interoperability testing of
isolation CSC with isolated tenants' networks. network isolation between the CSC
and CSP
43 – It is recommended that the IaaS CSP – 9.4 Interoperability testing of
provides the CSC with operations handling network isolation between the CSC
mechanisms related to isolated tenants' and CSP
networks, such as create, query and release.
44 7.3.5 Virtual – It is recommended that the IaaS CSP – 9.4 Interoperability testing of
Networking manages virtual networking to provide network isolation between the CSC
network connectivity amongst various and CSP
processing and storage resources.
45 7.3.6 Load – It is recommended that the IaaS CSP – 9.7 Interoperability testing of load
balance optimizes infrastructure resources utilization balance between the CSC and CSP
by providing load balance related functions,
such as throughput, response time, to avoid
overload of any one of the infrastructure
resources.
46 – The IaaS CSP can optionally provide – 9.9 Interoperability testing of
multipath routing to achieve an optimized multipath routing between the CSC
traffic management (e.g., to improve and CSP
network utilization, to guarantee QoS at
network congestion or fault).
