Carrier Ethernet refers basically to the endeavour to make Ethernet a carriergrade technology, as opposed to limited to a single companyâ€™s LAN. Carrier Ethernet has been much talked about in recent years, in particular thanks to the MEF (Metro Ethernet Forum). Many industry analysts have touted carrier Ethernet as a major source of growth for carriers and as basically meaning the end of traditional technologies such as PDH (Plesiochronous Digital Hierarchy: E1/E3 â€“ T1/T3 in the US), SDH (Synchronous Digital Hierarchy â€“ SONET in the US) and ATM (Asynchronous Transfer Mode) or Frame Relay. While there is indeed little doubt about the long term prospects for carrier Ethernet, we will argue in this article that the growth may be rather steady and gradual, and that the traditional technologies, directly or as an underlying technology, still have a few good years before them.
This article is based on a recent study completed by InfoCom, looking at market drivers and obstacles in general for carrier Ethernet while analysing in more details the current landscape in Germany as regards carrier Ethernet providers and offers.
Providers and offers overview: EoMPLS dominant
EoSDH v. EoMPLS
EoDWDM: for high bandwidth
VPN v. P2MP: P2MP so far most often sold
Market drivers and obstacles
Outlook - steady strong growth
