• In general transport platforms, a service has to be configured on every
network element via operational points. The management system has to know the topology.
• Goal is to minimize the number of operational points and increase scale • With the introduction of MPLS within the aggregation, some static per
service configuration is avoided. • Converged infrastructure delivers unified operational model for unicast and
multicast services 10

• The IP/MPLS Access Network adapts intelligently to
the Microwave Capacity drops • Microwave Adaptive Code Modulation changes due
to fading events are signaled through an Y.1731 VSM to the MPLS Access Node Aggregation Node
• The MPLS Access Node adapts the IGP metric of
the link to the new capacity, triggering optimized SPFs that account for the capacity drops
Aggregation Node
IP/MPLS interface
Policy Logic that updates the IGP metric on the IP/ MPLS interface
Degraded Link Cost = [n +1- n*CB/NB] * Original Link Cost Where: CB = Current BW, NB = Nominal BW, n = nodes in the ring
• In addition the Access Node can change the
