Challenges Facing Virtualized Telco Workload
Observation 4 - 30% Performance Loss on Hypervisor
Lack of Hard Real-Time Support from Hypervisor Scheduler.
We saw up to 10% Packet Loss
Non-Deterministic on Performance of Virtual Resources.
Easily Affected by Noisy Neighbors.
Lack of Coordinated Performance Management to acquire
Performance Metrics from Infrastructure
Need a Good Resource Management
Stability Worsened on Large-scale Deployment
CT Players Need Time to Learn to Communicate in the
Open Source Ways
Lack of Sufficient Training/Education Program

NFV Market Context
• Most of the Existing NFV Implementations are still Mainframe style
› Limited Benefit only from TCO saving
• NFV Ignites PC style Disruptions, both in Business Model and Technical
Architecture
› Mobile Device style will be Next
• The Market is Moving From Operator-Centric Toward User-Defined
› Focus Shifted from Operator to Operator’s Customers
• What is Amazon AWS Cloud Business Model in NFV Paradigm?
› Utility Computing vs Utility Networking
• What is the Technical Architectural Evolution that Enables Amazon
AWS Cloud like of Capabilities
› New Abstraction, Further De-composition, New Composition

• Network Hypervisor establishes an
abstraction that decouples
user/operator/dev’s goals from Host
(physical) Infrastructure
• Hypervisor Creates and Runs
“Guest Infrastructure”
• User Requirements and Policies are
Managed/Enforced via Hypervisor
• Red box dictates the scope of the
Platform
• Choices of Platform Location
• Think about Federation of
Hypervisors

OPNFV: Theory to Reality
• OPNFV will establish a carrier-grade integrated open
source reference platform to advance the evolution
of NFV
• The most important project will be a CI (Continuous
Integration) project
› Create an initial environment for development by
integrating upstream projects:
› Create automatic build and test process for
continuous integration work
› Create first OPNFV release
• Huawei is committed to the sucess of OPNFV and will
commit the resources needed.
› Contribute an integration team with up to 10 FTE.
• Huawei will also build a service orientated NFV test
lab for the community
