The three most important ones were identified to be
Ubiquitous Connectivity, Five-Nines availability, and End-to-End SLAs. However, all
the capabilities identified collectively in the figure inexorably allow Service Providers
to offer the entire gamut of carrier-class services, with the attendant QoS assurances
for mission-critical applications.
It is fair to assume, of course, that these feature capabilities, especially the ones
deemed most important (i.e., ubiquity, five-nines, SLAs) are not widely present/
available in the Service Providers??™ Carrier Ethernet offerings todays. In the next year
or so, the focus will invariably be on incorporating this set of features as completely as
possible in Carrier Ethernet (delivery) solutions.
Key Conclusions on the Current State of Carrier Ethernet Solutions
The current state of Carrier Ethernet delivery solutions is summarized next and characterizes
the transition underway from essentially delivering marginally carrier-oriented
Ethernet services to the Carrier Ethernet services as defined in Chapter 2.
8 It is fair to assume, of course, that these requirements are being driven by the (enterprise) end users.
