1. A method for adjusting modulation on a network, the method comprising:

setting a first modulation profile of a network node on the network at a first density;

monitoring a plurality of messages received at the network node;

updating the first modulation profile of the network node based on the monitored messages;

determining that a predetermined class of messages is received by the network node at an error rate that is greater than a predetermined error rate;

disconnecting the network node from the network based on the error rate of the received predetermined class of messages; and

reconnecting the network node to the network to re-initiate the network node on the network.

2. The method of claim 1 , wherein updating the first modulation profile includes updating the first modulation profile to a second density higher than the first density.

3. The method of claim 2 , wherein reconnecting the network node to initiate the network node on the network includes reconnecting the network node with a second modulation profile having a third density less than the second density.

4. The method of claim 3 , wherein the third density equals the first density.

5. The method of claim 1 , wherein the predetermined class of messages comprises modulation reports.

6. The method of claim 1 , wherein determining that the specified class of messages is being received incorrectly includes detecting that a predetermined number of messages of the specified class is not received in a predetermined time interval.

7. The method of claim 6 , wherein the predetermined number is four and the predetermined time interval is about ten seconds.

8. The method of claim 1 , wherein determining that a predetermined class of messages is being received incorrectly includes determining that dynamic interference is causing the predetermined class of messages to be received incorrectly.

9. A network node comprising:

a receiver that receives a plurality of messages;

a processor coupled to the receiver, the processor programmed to:

set a first modulation profile of the network node at a first density;

monitor the received messages on an ongoing basis;

update the first modulation profile of the network node continually based on the monitored messages;

determine that a predetermined class of messages is received incorrectly at the network node;

disconnect the network node from the network based on the incorrectly received predetermined class of messages; and

reconnect the network node to the network to initiate the network node on the network; and

a transmitter coupled to the processor, the transmitter transmitting data during initiation of the network node on the network.

10. The network node of claim 9 , wherein the processor programmed to update the first modulation profile to a second density higher than the first density.

11. The network node of claim 10 , wherein the processor programmed to reconnect the network node to initiate the network node on the network with a second modulation profile having a third density less than the second density.

12. The network node of claim 9 , wherein the predetermined class of messages comprises modulation reports.

13. The network node of claim 9 , wherein determining that the specified class of messages is being received incorrectly includes detecting that a predetermined number of messages of the specified class is not received in a predetermined time interval.

14. A network controller comprising:

a receiver that receives messages in support of a link maintenance operation (LMO) on a network;

a processor coupled to the receiver, the processor programmed to:

monitor the messages on an ongoing basis;

determine that a predetermined class of messages is not received correctly;

disconnect an LMO network node from the network based on the incorrectly received predetermined class of messages; and

reconnect the LMO network node to the network to initiate the LMO network node on the network; and

a transmitter coupled to the processor, the transmitter transmitting the messages in support of the LMO on the network.

15. A non-transitory computer readable storage medium having instructions stored thereon, the instructions when executed by a processor causing the processor to perform the operations of:

setting a first modulation profile of a network node on the network at a first density;

monitoring, on an ongoing basis, a plurality of messages received at the network node;

updating a first modulation profile of the network node continually based on the monitored messages;

determining that a predetermined class of messages is received incorrectly at the network node;

disconnecting the network node from the network based on the incorrectly received messages; and

reconnecting the network node to the network to initiate the network node on the network.

16. The non-transitory computer readable storage medium of claim 15 , wherein updating the first modulation profile includes updating the first modulation profile to a second density higher than the first density.

17. The non-transitory computer readable storage medium of claim 16 , wherein reconnecting the network node to initiate the network node on the network includes reconnecting the network node with a second modulation profile having a third density less than the second density.

18. The non-transitory computer readable storage medium of claim 15 , wherein the predetermined class of messages comprises modulation reports.

19. The non-transitory computer readable storage medium of claim 15 , wherein determining that the specified class of messages is being received incorrectly includes detecting that a predetermined number of messages of the specified class is not received in a predetermined time interval.

20. The non-transitory computer readable storage medium of claim 15 , wherein determining that a predetermined class of messages is being received incorrectly includes determining that dynamic interference is causing the predetermined class of messages to be received incorrectly.
