fiber optic cableVertical Systems Group 2010 U.S. Business Ethernet Leader board:

Based on latest research on enterprise network installations, the top eight Ethernet service providers in 2010 are:

  1. AT&T
  2. Verizon
  3. TW Telecom
  4. Cox
  5. XO
  6. Qwest
  7. Time Warner Cable
  8. Level 3

There was higher than expected market growth as enterprise customers were more positive about purchasing Layer 2 Ethernet services for ultra high bandwidth applications.  Ethernet port base grew 34% in 2010.

AT&T, Verizon and TW Telecom accounted for half of the retail Ethernet port base.

There were some interesting omissions from the 2010 leader board.  Cogent was knocked off the list by Level 3.  Sprint, once part of the “big three”, did not make the top eight.

The top eight companies make up 80% of the total 2010 U.S. retail Ethernet port base.
