In a Mobile backhauling scenario, network scalability is limided by the number of services which can be managed by a single FlexiPacket device at Edge site on a UNI interface (where all services are collected)
More devices can be stacked at Edge site to increase network scalability
In the depicted example network scalability is doubled. Half a services go through violet path, half a services go through blue path.
