In this case, a Service Provider with a different access infrastructure (SONET, TDM, fiber, copper) at different locations within its footprint is serving a medium-sized enterprise with offices at each of these locations and a couple outside Requiring a standardized (and consistent) Ethernet service across these customer locations (albeit with the bandwidth varying between 10 and 100M) is an increasingly common scenario The Service Provider may consider introducing a simple Ethernet Demarcation Device (EDD) based solution (see 2 for some details on EDD) with the corresponding network links (OC-n, T1, Ethernet-over fiber/copper) This is shown in Figure 164 and provides a cost-effective solution that enables offering a standardized Ethernet handoff rapidly, irrespective of the last/first mile infrastructure and without disrupting this infrastructure By employing an EDD, it can also extend this standardized offering over the leased facility (from another operator) to support out-of-region customer locations These fairly straightforward scenarios depict that often more than a single solution is feasible in a particular environment and also that multiple solutions frequently coexist in the same Service Provider network Obviously, more complex offerings would make the underpinning delivery solutions more involved It bears repitition that the solutions described in each of the above scenarios are not necessarily the only feasible options

Ethernet Service Provider requirements for competitive advantage (Source: Heavy Reading,
competitive advantage8 These are shown in Figure 165 and note the key features that were deemed important As should be evident, they align very closely with the feature attributes of Carrier Ethernet 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 (ie, 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 2
It is fair to assume, of course, that these requirements are being driven by the (enterprise) end users

Several Solutions Exist There are numerous solutions (most of them are described in Part II) currently used to deliver Carrier Ethernet services; multiple solutions exist because multiple incumbent solutions were being used in Service Provider networks to deliver services (not necessarily Ethernet), and these solutions evolved to incorporate delivery of Carrier Ethernet (to some extent) The Solutions Are Usually Fundamentally Different Most of the solutions are very different from each other, from the type of physical infrastructure they support to the functionality, manageability, and provisioning as evidenced by the comparison earlier in the chapter The Solutions Have Different Focuses Most solutions today are primarily focused on bridging the chasm in metro access between the customer premise location and the Service Provider s first Point Of Presence (POP) Several, however, are focused on delivering Carrier Ethernet in the metro and beyond, in to the WAN It must be noted that realistically, even if a solution can be deployed across the metro and the core, it is likely these solutions will be packaged in different commercial offerings (ie, two different models), each addressing a different segment Differing price sensitivities in the various segments make it unrealistic to have a one box solution across segments (without being economically unattractive) Carrier Ethernet Is Still Evolving and So Are the Solutions A fundamental challenge to Carrier Ethernet solutions is that Carrier Ethernet is still very much in its infancy and in the process of standardizing and evolving to support the next generation of applications Within such a dynamic context, the solutions are also invariably evolving to align with these developments; albeit it must be noted that solution vendors, in an attempt to competitively differentiate, often offer new features that may still not be ratified by standards bodies However, as shown in Figure 165, there appears to be a long way to go even with regards to making available most of the fairly well-defined Carrier Ethernet attributes There Is No One All Encompassing Solution There is no one solution that is both economical and has adequate features to support the delivery of Carrier Ethernet from simple point-to-point E-Line connectivity in the access to a multipoint solution in the core of the Service Provider network Therefore, it is not uncommon for Service Providers to employ multiple solutions in their networks, perhaps one in the access and another, deeper in the metro
