Probing network nodes for optimization
View Patent ↗A method is disclosed for optimizing a network that is formed from a plurality of nodes. The NC node of the network compiles an order that the plurality of nodes perform a probing operation. The order is typically round robin. The NC node receives a request from a client that identifies a next node to perform the probing operation. Based on the request, the NC node changes the order so that the next node performs the probing operation after the current node that is performing the probing operation has completed the operation.
1. A method of optimizing a network that comprises a plurality of nodes, the method comprising:
determining an order in which the plurality of nodes perform a bitloading operation to determine a proper bitloading on the paths between the nodes of the network;
receiving a request from a first node, wherein the request identifies a next node to perform the bitloading operation; and
changing the order so that the next node performs the bitloading operation after a current node that is performing the bitloading operation.
2. The method of claim 1 , wherein the bitloading operation comprises the next node initiating a message to the other nodes within the plurality of nodes of the network.
3. The method of claim 2 , wherein the message comprises a predetermined bit sequence.
4. The method of claim 2 , wherein the message is processed by a receiving node to estimate a channel characteristic between the next node and the receiving node.
5. The method of claim 1 , wherein the bitloading operation is a link maintenance operation.
6. The method of claim 1 , wherein the next node is the first node.
7. The method of claim 1 , wherein the next node is one of the plurality of nodes other than the first node.
8. The method of claim 1 , wherein the order is a round robin order.
9. The method of claim 1 , wherein changing the order comprises tracking for each of the nodes when the node last performed a bitloading operation.
10. A device for optimizing a network having a plurality of nodes, the device comprising:
means for determining an order that the plurality of nodes perform a bitloading operation to determine a proper bitloading on the paths between the nodes of the network;
means for receiving a request from a first node, wherein the request identifies a next node to perform the bitloading operation; and
means for changing the order so that the next node performs the bitloading operation after a current node that is performing the bitloading operation.
