Achievements through NFV trial
1. Software and hardware
decoupling
2. VNF on-boarding,
update and scaling
3. MANO function ,
interface test with indirect
mode
4. The IOT test of NFVO-

✓ Provide consistant VNF package format
✓ Provide consistant Mgmt procedure for VNF package
✓ Standard HW mgmt interface
✓ Resource orchestrate in a vendor’s HW pool
✓ Resource allocation with the indirect mode.
✓ FCAPS mgmt. and the VNF lifecycle mgmt.

To fully achieve the ability of NFV , we still need …
For the NS orchestration, still much work to do
• HW/SW decoupling to
HW/Hypervisor/VNF decoupling.
• Standard the VNFD
• Build an openness VNF eco-system,
design a standard G-VNFM.
• Standard the NSD based on the
standard VNFD.

Standard VNFD
VNFD: Virtual network function descriptor.
Standard VNFD ：
• Benefit the network topology analysis and the display.
• Benefit the technical to understand the NW resource to orchestrate.
• The pre-condition for G-VNFM.
• The pre-condition for standard the NSD.
Standard VNFD in ETSI:
• A plan have been published to standard the VNFD with TOSCA in the SOL001.• The plan allow vendor to expand the definition with TOSCA, differentiate will be introduced.

G-VNFM: Multi-vendor VNF orchestrate
• VNF life-cycle mgmt. for multi-vendor
VNF use Vn-Vnfm-Vn interface.
• VNF O&M for multi-vendor VNF with
EMS use Vn_Vnfm-em interface.
• Multi-vendor VNF orchestration ,
avoid vendor lock.

NSD( Network Service Descriptor)
• NSD describe the requirement of network
service, and the relationship of the required
NW resources.
• The VNF will be created follow the
requirement of the NSD.
• The standard of NSD will benefit the
automation service fulfillment.

OSS architectures must evolve along the following lines:
Evolving of the OSS
▪ Taking a holistic view of operations rather than the current piece-meal approach?
▪ Inheriting terms and definitions from standards rather than creating a separate language?
▪ Flexible architectures rather than static interface definitions?
▪ Full automation of the capacity management,optimization and reconfiguration cycle should be done by
orchestration and cloud management techniques with open and multivendor components rather than
vendor-specific management solutions.
▪ OSS focusing on portfolio management and end-to-end service management
▪ ……..

To be solved through the trial
Issues to be solved
▪ How to deal with the relationship between the legacy OSS and NFVO?
▪ How to manage the hardware FCAPS( such switches and firewalls) in NFV architecture?
▪ How to deploy the MANO (centralized or in province)?
▪ How to deploy the VAS service considering that VAS vendor can’t offer VNFM
▪ How could we operate the hybrid network (the structure of the organization and operator’s skill)
▪ ……..
