Abstract
Method and nodes are provided for propagating between the nodes information about processing capacity of peer nodes. Two types of signals are sent from propagating nodes towards their peer nodes. A propagating node sends first signal type at a constant rate and a second signal type at a variable rate. A ratio of the rates calculated at a peer node represents the processing capacity available a propagating node. Sequence numbers may be added to signals of the first and second type in order to assist peer nodes in detecting capacity issues.
Claims25
A method of obtaining information about a processing capacity of a node, the method comprising the steps of:
- receiving from the node a first signal at a first rate;
- receiving from the node a second signal at a second rate;
- calculating a ratio between the second rate and the first rate;
- and
- determining the processing capacity of the node based on a comparison of the ratio with a preset value.
A method of propagating information about a processing capacity of a node, the method comprising the steps of:
- determining an offered capacity value, the offered capacity value being equal to or less than a preset value indicative of a normal processing capacity of the node;
- sending from the node a first signal periodically at a base rate;
- and
- sending from the node a second signal periodically at a second rate indicative of the offered capacity value.
A node for propagating information about its processing capacity, comprising:
- a processor;
- a load indicator adapted to indicate a load level of the processor;
- one or more interfaces adapted to send signals towards peer nodes;
- and
- a control logic adapted to:
- read the load level of the processor;
- request the one or more interfaces to send a first signal at a first rate;
- calculate a second rate based on a comparison of the load level and of a maximum amount of processing capacity of the node;
- and
- request the one or more interfaces to send a second signal at the second rate.
A node for obtaining information about a processing capacity of a peer node, comprising:
- one or more interfaces adapted to receive signals from the peer node;
- and
- a control logic adapted to:
- receive from the one or more interfaces a first signal multiple times;
- determine a first rate of the first signal;
- receive from the one or more interfaces a second signal multiple times;
- determine a second rate of the second signal;
- calculate a ratio between the second and first rates;
- and
- store in a peer table a processing capacity of the peer node based on the ratio.
