Case Study: China Telecom NFV Smartpipe on Intel® ONP
Problem Statement:
• Carrier Grade Service Function Chaining requires:
- Process heavy IP Edge user session
- Services provisioning, redundancy, upgrade
- Scalable Packet processing performance
- Resources pool monitoring, troubleshooting
• Current IP Edge solution landscape:
- Lack of multi levels flow table & programmable capability
- Lack of services feature, long development cycle
- Lack of flexibility and interoperability
- Single blade performance limitation

performance. Consult other sources of information to evaluate performance as you consider your purchase. For more complete information about performance and
benchmark results, visit http://www.intel.com/performance.
Cost reduction scenarios described are intended as examples of how a given Intel-based product, in the specified circumstances and configurations, may affect future
costs and provide cost savings. Circumstances will vary. Intel does not guarantee any costs or cost reduction.

number of risks and uncertainties. A detailed discussion of the factors that could affect Intel’s results and plans is included in Intel’s SEC filings, including the annual
report on Form 10-K.

Risk Factors
The above statements and any others in this document that refer to plans and expectations for the first quarter, the year and the future are forward-
looking statements that involve a number of risks and uncertainties. Words such as "anticipates," "expects," "intends," "plans," "believes," "seeks,"
"estimates," "may," "will," "should" and their variations identify forward-looking statements. Statements that refer to or are based on projections,
uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel's actual results, and variances from Intel's
current expectations regarding such factors could cause actual results to differ materially from those expressed in these forward-looking statements.
Intel presently considers the following to be important factors that could cause actual results to differ materially from the company's expectations.
Demand for Intel’s products is highly variable and could differ from expectations due to factors including changes in the business and economic
conditions; consumer confidence or income levels; customer acceptance of Intel’s and competitors’ products; competitive and pricing pressures,
including actions taken by competitors; supply constraints and other disruptions affecting customers; changes in customer order patterns including
order cancellations; and changes in the level of inventory at customers. Intel’s gross margin percentage could vary significantly from expectations based
on capacity utilization; variations in inventory valuation, including variations related to the timing of qualifying products for sale; changes in revenue
levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; excess or obsolete inventory; changes in unit
costs; defects or disruptions in the supply of materials or resources; and product manufacturing quality/yields. Variations in gross margin may also be
caused by the timing of Intel product introductions and related expenses, including marketing expenses, and Intel’s ability to respond quickly to
technological developments and to introduce new features into existing products, which may result in restructuring and asset impairment charges.
Intel's results could be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers or its
suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and fluctuations in
currency exchange rates. Results may also be affected by the formal or informal imposition by countries of new or revised export and/or import and
doing-business regulations, which could be changed without prior notice. Intel operates in highly competitive industries and its operations have high
costs that are either fixed or difficult to reduce in the short term. The amount, timing and execution of Intel’s stock repurchase program and dividend
program could be affected by changes in Intel’s priorities for the use of cash, such as operational spending, capital spending, acquisitions, and as a result
of changes to Intel’s cash flows and changes in tax laws. Product defects or errata (deviations from published specifications) may adversely impact our
expenses, revenues and reputation. Intel’s results could be affected by litigation or regulatory matters involving intellectual property, stockholder,
consumer, antitrust, disclosure and other issues. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from
manufacturing or selling one or more products, precluding particular business practices, impacting Intel’s ability to design its products, or requiring
other remedies such as compulsory licensing of intellectual property. Intel’s results may be affected by the timing of closing of acquisitions, divestitures
and other significant transactions. A detailed discussion of these and other factors that could affect Intel’s results is included in Intel’s SEC filings,
including the company’s most recent reports on Form 10-Q, Form 10-K and earnings release.
