Shitao li (huawei)

2. tosca-nfv-profile Latest draft: tosca-nfv-v1.0-wd01-rev09
Main features updated in this draft:
Re-write the definition of tosca.nodes.nfv.VDU
Add new capability and data types:
tosca.capabilities.Compute.Container.Architecture
tosca.datatypes.compute.Container.Architecture.CPUAllocation
tosca.datatypes.compute.Container.Architecture.NUMA
Add new properity “anti_spoof_protection” for CP node type
maps to OpenStack Neutron’s port_security_enabled flag
Add VNFD examples
Delete high available related feature (requirement is not clear, the group decides to remove this feature from this version)

3. VDU definition
tosca.nodes.nfv.VDU:
derived_from: tosca.nodes.Root
capabilities:
nfv_compute:
type: tosca.capabilities.Compute.Container.Architecture
virtualbinding:
type: tosca.capabilities.nfv.VirtualBindable
monitoring_parameter:
type: tosca.capabilities.nfv.Metric requirements:
Neither Software component node type nor Compute node type can fulfill the VDU requirements as defined in ETSI NFV.
The VDU type will derived directly from tosca Root type.
Add a new capability nfv_compute to fulfill the VDU requirement for virtual resources.

properties:
mem_page_size:
type: scalar-unit.size
required: false
constraints:
- [normal, huge]
cpu_allocation:
type: tosca.datatypes.compute.Container.Architecture.CPUAllocation

Description
mem_page_size No
string
One of:
small
large
any
custom mem in MB
Default: any
Describe page size of the VM
small page size is typically 4KB
large page size is typically 2MB
any page size maps to system default
custom MB value: sets TLB size to this specific value
cpu_allocation no
CPUAllocation
Describes CPU allocation requirements like dedicated CPUs (cpu pinning), socket count, thread count, etc.
numa_nodes
map of NUMA
Granular Non-Uniform Memory Access (NUMA) topology of vCPU and Memory across CPU sockets and memory banks.
