However, this need not be the case if networks are operated correctly. As
discussed already, the EoMPLS architecture constrains service provisioning to the PE
devices at the edges of the network, freeing the operator from the burden of having to
provision connections through core elements (as is often the case in Layer 2 Ethernet
networks or on SDH/SONET networks, though such networks often automate the provisioning
process using network management tools). Network management tools may
also be added to MPLS to simplify configuration and fault management, and, in fact, it
is sometimes observed that the service layer of an EoMPLS network should be operated
from a service management platform in a similar fashion to a Frame Relay network,
but the network layer should be operated using IP/MPLS tools.
Vendors Promoting This Solution
Because the Ethernet over MPLS solution is based on publicly available IETF standards,
any vendor who chooses to implement it may do so. Thus, any list of vendors is
necessarily incomplete. However, the table below summarises some of the key vendors
and products implementing Ethernet over MPLS.
