Benefits
-
The IP/MPLS access network adapts intelligently to the microwave capacity change by:
-
optimizing routing
-
controlling congestion
-
enabling loss protection.
-
-
Microwave ACM changes are signaled through a Y.1731 VSM/G.8031/Y.1731 (ETH-BNM) to the IP/MPLS access node.
-
The IP/MPLS access node adapts the IGP metric of the link to the new capacity.
-
The IP/MPLS access node can change the H-QOS policy on the interface with the microwave system allowing EF traffic to survive.
-
The IP/MPLS access node can remove a degraded link from SPF triggering a loss protection.
