Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 6, 2015, the Company acquired all of the outstanding capital stock of Codemate A/S and its wholly owned subsidiary Octoshape ApS ("Octoshape") in exchange for $107.5 million in cash, subject to post-closing adjustments. The allocation of the purchase price has not been finalized as of the date of the filing of these financial statements. The goal of acquiring Octoshape is to provide customers with the most comprehensive suite of delivery and optimization technologies for video streams of over-the-top (OTT) content and to enable Internet Protocol television (IPTV) solutions. Pro forma results of operations for the acquisition of Octoshape have not been presented because the effects are not material to the Company's consolidated financial statements.
