?– Equipment (both customer and network) needs to incorporate configuration management
as defined in the E-LMI specification (MEF 16). This would enable such
equipment to automate, and hence simplify configuring the increasingly sophisticated
services.
?– Timing synchronization specifications have gained some urgency as carriers are
beginning to migrate TDM services to converged Ethernet networks. (MEF has
begun addressing in the mobile backhaul project).
Scalability
?– A standard Carrier to Carrier interconnection specification is required (The E-NNI
effort has commenced by the MEF)
?– A standardized access interconnection for emerging access methods is required
(MEF has begun developing the Service Node Interface, SNI)
?– A dynamic control plane solution is required to enable automated provisioning.
?– Overcome the VLAN/MAC limitations (actively being addressed by the PBB, MPLS
etc as noted previously in the chapter)
?– Efficiently forcing customer specific traffic only on some backbone links (Multiple
Registration Protocol, MRP, per IEEE 802.1ak has begun focusing on this capability).
Reliability
?– Standardized SNI required to provide an efficient method of introducing resilient
access solutions in the metro.
