Even though Carrier Ethernet is designed to offer
bandwidth anywhere from 1 Mbps in fine increments of 1M or even less (in fact, this
is considered one of its big advantages as noted in Chapter 1), less than 10 M is not
in reality being offered. This speaks to enforcing the Carrier Ethernet defined UNI to
leverage the market opportunity.
Economics One big advantage of carrier Ethernet services is the economics for both the
Service Providers and enterprise end users. However, as these services are currently being
delivered over numerous underlying technologies (refer to Part II for a discussion on
these), the economics may be less attractive (as opposed to delivering native Ethernet).
Further, because pricing of Carrier Ethernet services is combined with other application
services such as Internet access, the true cost of Carrier Ethernet is hard to discern.
Interoperability In a LAN Ethernet, enterprise customers have come to expect that
any device, from any manufacturer with a standard Ethernet port, can be easily deployed
in their LAN. A similar expectation is assumed by Service Providers when it
comes to Carrier Ethernet; after all, their networks are akin to a LAN and any Carrier
Ethernet equipment from multiple vendors deployed over these networks should inter-
work and provide consistent services and, of course, offer the features and tools to
provision and manage these services.
