Multi-Carrier ABC Overview
Multi-Carrier Adaptive Bandwidth Control (ABC) enables multiple separate
radio carriers to be shared by a single Ethernet port. This provides an
Ethernet link over the radio with the total sum of the capacity of all the radios
in the group, while still behaving as a single Ethernet interface. In
Multi-Carrier ABC mode, traffic is dynamically divided among the carriers, at
the Layer 1 level, without requiring Ethernet Link Aggregation.
Load balancing is performed regardless of the number of MAC addresses or
the number of traffic flows. During fading events which cause ACM modulation
changes, each carrier fluctuates independently with hitless switchovers
between modulations, increasing capacity over a given bandwidth and
maximizing spectrum utilization. The result is 100% utilization of radio
resources in which traffic load is balanced based on instantaneous radio
capacity per carrier.
One Multi-Carrier ABC group that includes both radio interfaces can be
configured per unit.
