Whether there are restrictions on the number of TE links on an optical-layer ASON network or an electrical-layer ASON network

On an optical-layer ASON network, a TE link can only be created between FIU boards. The quantity of TE links is determined by the NE scale of the network. Generally, only a few TE links are configured on the network.
On an electrical-layer ASON network, ODUk links of different levels can be created based on line board types. Generally, a large number of TE links are configured on the network. An electrical-layer ASON network has far more TE links than an optical-layer ASON network.
More links on a network will consume more network resources. Therefore, it is required that an electrical-layer ASON network be smaller than an optical-layer ASON network.
