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.
