Vertical Systems Group today released its 2011 U.S. Business Ethernet Leaderboard, featuring the leading carriers according to Ethernet port market share. The 2011 year-end report showed fairly little change versus the mid-year 2011 report, but one notable movement was XO Communications rising from the seventh position at mid-year to the fifth position at the end of the year.
The year-end leaders in order were: AT&T (NYSE: T), Verizon (NYSE: VZ), tw telecom (Nasdaq: TWTC), Cox Communications, XO, CenturyLink (NYSE: CTL) (includes Qwest and Savvis), Time Warner Cable (NYSE: TWC) , Level 3 (NYSE: LVLT) (includes Global Crossing), and Cogent (Nasdaq: CCOI). All of those companies made the leaderboard by virtue of having at least 4 percent or more of billable port installations, according to VSG.
Besides the change with XO, Cox moved from fifth to fourth place, and CenturyLink was listed in sixth place. The top group of providers accounted for more than 75 percent of the business Ethernet ports in the market.
VSG also listed a "challenge-tier" of service providers who didn't make the 4 percent threshold. That group included: Abovenet (NYSE: ABVT), Charter Business (Nasdaq: CHTR), Comcast Business (Nasdaq: CMCSA), Optimum Lightpath, Reliance GlobalCom and Windstream (Nasdaq: WIN) (includes PAETEC).
