Accounting Policies [Abstract]
Investments	The Company considers highly liquid investments with maturities of three months or less at the date of purchase to be cash equivalents. Investments with original maturities of greater than three months, but less than one year at the balance sheet date are classified as Short-term investments. The Company accumulates unrealized gains and losses on the Company's available-for-sale debt securities, net of tax, in accumulated other comprehensive income (loss) in the stockholders' equity section of its balance sheets. If the fair value of an available-for-sale debt instrument is less than its amortized cost basis, an other-than-temporary impairment is triggered in circumstances where (1) the Company intends to sell the instrument, (2) it is more likely than not that the Company will be required to sell the instrument before recovery of its amortized cost basis, or (3) the Company does not expect to recover the entire amortized cost basis of the instrument (that is, a credit loss exists). The Company determines the basis of the cost of a security sold or the amount reclassified out of accumulated other comprehensive income (loss) into earnings using the specific identification method.
Deferred Revenue	Deferred Distributors Revenue, Net of Cost of Sales to Distributors The Company records revenue from its distributors on a sell-through basis, recording deferred revenue and deferred cost of sales associated with all sales transactions to its distributors in “Deferred distributor' revenue, net of cost of sales to distributors” in the liability section of its condensed consolidated balance sheet. The amount shown as “Deferred distributors revenue, net of cost of sales to distributors” represents the deferred gross profit on sales to distributors based on contractual pricing. The Company offers for sale to its customers, renewable support arrangements that range from one to five years. Deferred support revenue is included within deferred revenue, net within the services category above. Deferred Revenue, Net Deferred revenue, net represents amounts for (i) deferred services revenue (support arrangements, professional services and training), and (ii) deferred product revenue net of the related cost of revenue when the revenue recognition criteria have not been met.
Guarantees and Product Warranties	Guarantees and Product Warranties Upon issuance of a standard product warranty, the Company discloses and recognizes a liability for the obligation it assumes under the warranty. The Company has agreed to hold the customer harmless against losses arising from a breach of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is not estimable. We have not recorded a liability related to these indemnification and guarantee provisions and our guarantee and indemnification arrangements have not had any significant impact on our consolidated financial statements to date.
Fair Value Measurements	Level 2 investment valuations are based on inputs such as quoted market prices of similar instruments, dealer quotations or valuations provided by alternative pricing sources supported by observable inputs. These generally include U.S. government and sovereign obligations, most government agency securities, investment-grade corporate bonds, and state, municipal and provincial obligations.
Earnings Per Share	Basic earnings per share is calculated by dividing net earnings by the weighted average number of common shares outstanding during the period. Dilutive earnings per share is calculated by dividing net earnings by the weighted average number of common shares used in the basic earnings per share calculation plus the dilutive effect of shares subject to repurchase, options, warrants and unvested restricted stock.

Disclosure of accounting policy for computing basic and diluted earnings or loss per share for each class of common stock and participating security. Addresses all significant policy factors, including any antidilutive items that have been excluded from the computation and takes into account stock dividends, splits and reverse splits that occur after the balance sheet date of the latest reporting period but before the issuance of the financial statements.
