However, the transport layer remains a large
and integral component of service delivery. Standardized services depend on a predictable
transport layer??”one that operates consistently over different portions of the
network and different vendors??™ implementations and transparently under a variety of
packet-level implementations and a range of standardized service types. EoS solutions
excel at providing predictable transport for standardized Carrier Ethernet services.
Moreover, EoS solutions allow service providers to use the enormous installed based
of SONET equipment, which helps make those services more ubiquitous??”another key
factor in the delivery of standardized Carrier Ethernet services.
While EoS networks can also meet the other two key attributes, scalability and service
management, these attributes tend to depend almost exclusively on the functions at the
packet layer, and very little on the functions of the underlying transport network.
When Does This Solution Fit?
At a high level, EoS enables service providers to leverage the strengths of SONET
technology and its massive installed base to cost-effectively deliver Ethernet services.
