Bharatbook.com is proud to announce the report "Carrier Ethernet Services" to their offering.

PRLog (Press Release) – May 27, 2008 – Ethernet, the protocol that is ubiquitous in enterprise local area networks, is now being offered by service providers as a metro or wide area service. These publicly available Ethernet services have been among the communications market’s fastest growing segments, with carriers enjoying revenue growth in the range of 30 percent annually as enterprises large and small opt for these new services that are being offered in an array of speeds and reach.

Carrier Ethernet offers the chance to tie customer locations together in what appear to be virtual LANs that can stretch across a metropolitan area, a region, the nation, or the world. Carrier Ethernet offers significant advantages in cost and simplicity and in facilitating convergence—and is often touted as a replacement for legacy data solutions like private line and frame relay. This Insight study projects market size, growth, and revenue, including segmented breakdowns of point-to-point and any-to-any services as well as by interface levels ranging from 10Mbit/s to the emerging 10Gigabit standard. This report provides insight into this emerging arena that will fundamentally shape the communications market of the future.

Report Excerpt

1.1 Carrier Ethernet

Ethernet is the world’s dominant machine-to-machine (computer-to-computer) interface protocol, with interfaces on more than 300 million computers worldwide—and it is fast becoming a potent force in metro and wide-area communications.

Carrier Ethernet is still in an early growth stage. Second only to IP in terms of growth potential and influence on the communications market, Ethernet has become an increasingly prominent feature of the national data networking landscape in the US. As of late 2006, Ethernet services are available from virtually all major data service providers, including incumbents, second-tier carriers, and smaller specialized players differentiating themselves by price, technology, and flexibility.

Until recently, Carrier Ethernet services have generally earned the label “metro Ethernet.” The large majority of Ethernet service has been, and still is, between points within a metropolitan area. It is only relatively recently that Carrier Ethernet has become a more widely accepted service available into the long-haul, though this has not been marketed in any significant way. This may change in 2007 as major incumbents—particularly AT&T and Verizon—plan to introduce long-haul Layer 2 virtual private networks (VPNs) in 2007.

INSIGHT’s use of the term “Carrier Ethernet” refers to any Layer 2 public network service that extends Ethernet beyond the local area network (LAN) and connects to customers through Ethernet interfaces. Carrier Ethernet may be marketed as transparent or native LAN, Ethernet, Gigabit Ethernet, GigE, metro Ethernet, Ethernet private line (EPL), Ethernet virtual private line (EVPL), Layer 2 virtual private network (VPN), Ethernet access, virtual private LAN service (VPLS), or a variety of other names. INSIGHT’s definition does not, however, include routed Layer 3 IP-VPN services, which also carry IP over Ethernet. Carrier Ethernet services include relatively longstanding legacy transparent or native LAN services, whether asynchronous transfer mode (ATM)-based within the network core or using an Ethernet over fiber (or SONET) architecture. Our definition also includes newer services from small and large carriers that variously deliver end-to-end Ethernet directly over optic fiber, encapsulate Ethernet packets in SONET, or transmit it over dense wavelength division multiplexing (DWDM) wavelengths or as Ethernet over multi protocol label switching (MPLS).

Ethernet can be segmented by its speed (10Mbit/s-100Mbit/s; 100Mbit/s-1Gbit/s; >1Gbit/s), by the nature of its sale (retail vs. wholesale), by the region the service covers, and by topology, which refers to whether the service delivery can be characterized as E-line or E-LAN.

E-line is an Ethernet service structurally similar to a private line. E-line point-to-point service provides a Layer 2 private line or virtual private line (VPL) on Ethernet between two locations.

E-LAN service, by contrast, structurally resembles a LAN. It provides the potential for multipoint-to-multipoint Layer 2 service. Each user network interface (UNI) in an E-LAN service connects to a multipoint Ethernet virtual connection (EVC)…
