We were happy and proud to learn that Frost & Sullivan had bestowed its 2015 Business Metro Carrier Ethernet Services Market Leadership Award to AT&T.
In fact, AT&T has ranked number 1 in Frost & Sullivan’s market share analysis of the retail Ethernet market over the past 5 years. “AT&T continues to lead through a combination of deep metro network footprint, market leading Ethernet solutions and high-performance service level agreements (SLAs),” says Frost & Sullivan
AT&T and customers, old and new, are migrating from time-division multiplexing (TDM) private line technology to Ethernet service to take advantage of scalability, reliability, and cost efficient bandwidth.
“In 2014, AT&T controlled nearly 23% of the metro market share,” Frost & Sullivan points out, adding that “AT&T continues to lead through a combination of deep metro network footprint, market leading Ethernet solutions and high-performance service level agreements (SLAs).”
With a range of bandwidth and configuration options that reach gigabit speeds, AT&T Ethernet service can be adapted to meet virtually any challenge. AT&T Switched Ethernet ServiceTM can connect multiple sites with high speed and provides flexibility to grow as an enterprise evolves and new business opportunities emerge.
“Since AT&T switched Ethernet service is able to fulfill stringent performance criteria, its Layer-2 [Ethernet Virtual Private Line] service is driving market migration from dedicated traditional private lines to Ethernet,” Frost & Sullivan notes.
The market research firm also points out that AT&T Network on Demand offer, launched in September 2014, “enables business customers to order network services on-demand. Customers use a self-service portal to choose and order network capacity as needed. A high level of automation into the process reduces complexity of ordering and provisioning Ethernet circuits.”
Most important, Frost & Sullivan says, is that Network on Demand speeds delivery time – reducing bandwidth provisioning to seconds for ports and physical circuits already in place, as opposed to days. “Customers also benefit from lower cost of ownership as they only pay for what they use, instead of the fixed monthly recurring charges,” according to the firm.
Both Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL) configurations are seeing increased growth as replacements to TDM circuits and Ethernet-LAN services are a cost-effective and reliable alternative for customers migrating from ATM and Frame Relay networks.
Not giving up MPLS
When it comes to virtual private networks, however, Frost & Sullivan says most enterprises continue to prefer Layer 3 Multiprotocol Label Switching (MPLS) VPNs over Ethernet Virtual Private LAN Services for multi-site connectivity.
VPLS may not meet the needs of networks that are not meshed, where Ethernet connectivity is not needed, in cases where a large number of sites need to communicate within a network, or when an enterprise wishes to advertise IP Routes. In addition, due to some geographic coverage limitations, MPLS VPN with IP addressing may be a better fit for larger networks requiring many routes. However, with SDN, universal ports can be provisioned that enable enterprises to provision Ethernet or VPN WAN service in real-time.
