In order of retail port share, the companies on the leaderboard are AT&T, Level 3, Verizon, CenturyLink, Time Warner Cable, Comcast, Cox, XO and Windstream. To qualify for VSG's Leaderboard, a provider must have 4 percent or more of the U.S. Ethernet services market.
"For the full year 2015, the Ethernet market grew by more than 20 percent, however the second half of the year showed moderating growth going into 2016," said Rick Malone, principal at Vertical Systems Group, in a statement. "During this cycle, Windstream moved up to the Leaderboard from the Challenge Tier based on the strength of its Ethernet private line service and its presence in many smaller markets that others do not serve."
