new entity, called the QoS controller. The QoS controller’s role is to assign channel |
| |
access to the different networks. The QoS controller acts at the same time as the |
| |
AP of one of the networks. In the presence of several networks, the coexistence | 33 | |
protocol automatically selects one of the APs as the QoS controller. | ||

4.2.2.1 Two Networks on Different Circuits |
| |
If two |
| |
the adapters belonging to different networks, then these two networks will behave |
| |
as two independent networks. Both APs will act as QoS controllers. |
| |
4.2.2.2 Two Networks on the Same Circuit |
| |
Different networks are defined by different network IDs. |
| |
If two |
| |
protocol will act as if there were only one network. The network ID is transmitted |
| |
by every adapter to communicate the existence of its network. If an adapter with |
| |
network ID A receives network ID B, then it knows that there are at least two |
| |
networks sharing the channel. |
| |
For example, one |
| |
network is configured and becomes active. Then the second network will notify |
| |
the first network of its existence in some specified access slots, and both networks |
| |
will automatically be reconfigured and will share the channel. If both networks are |
| |
configured at the same time, the QoS controller will be selected from all available |
| |
APs. |
