DA Davidson analyst Mark Kelleher compares the networking technology at Limelight Networks (LLNW) versus that of Akamai (AKAM), saying that because Limelight is more centrally organized across its 84 data centers, it can deliver information with less internet congestion. Kelleher notes that he recently discussed the contrast with Limelight CFO Sajid Malhotra, who explained that customers are willing to pay more for this type of content delivery relative to Akamai, which places its Content Delivery Network within the data centers of its ISP partners. While Akamai's CDN is more advantageous for smaller content like web pages, Kelleher says the rapid growth in video is quickly creating congestion problems for its network. The analyst has a Buy rating on Limelight Networks, nudging his price target to $7 from $6 based on the company's return to top-line growth, as well as improved operating margins, cash flow, and positive earnings.
