Abstract
In one embodiment, a processor receives observed node characteristics of a node in a network. The node characteristics include a link cost metric for a network link associated with the node. The processor uses a Bayesian learning model to estimate a virtual link cost metric based on the observed node characteristics. The model uses statistics regarding the observed link cost metric as background belief measures. The processor forms a routing path in the network that includes the network link in part based on an objective function that uses the virtual link cost metric as a parameter.
Claims20
A method comprising:
- receiving, at a processor, observed node characteristics of a node in a network, wherein the node characteristics include a link cost metric for a network link associated with the node;
- using, by the processor, a Bayesian learning model to estimate a virtual link cost metric based on the observed node characteristics, wherein the model uses statistics regarding the observed link cost metric as background belief measures;
- and
- forming, by the processor, a routing path in the network that includes the network link in part based on an objective function that uses the virtual link cost metric as a parameter.
An apparatus, comprising:
- one or more network interfaces to communicate with a network;
- a processor coupled to the network interfaces and configured to execute one or more processes;
- and
- a memory configured to store a process executable by the processor, the process when executed configured to:
- receive observed node characteristics of a node in a network, wherein the node characteristics include a link cost metric for a network link associated with the node;
- use a Bayesian learning model to estimate a virtual link cost metric based on the observed node characteristics, wherein the model uses statistics regarding the observed link cost metric as background belief measures;
- and
- form a routing path in the network that includes the network link in part based on an objective function that uses the virtual link cost metric as a parameter.
A tangible, non-transitory, computer-readable medium storing program instructions that cause a processor of a device to execute a process comprising:
- receiving, at the processor, observed node characteristics of a node in a network, wherein the node characteristics include a link cost metric for a network link associated with the node;
- using, by the processor, a Bayesian learning model to estimate a virtual link cost metric based on the observed node characteristics, wherein the model uses statistics regarding the observed link cost metric as background belief measures;
- and
- forming, by the processor, a routing path in the network that includes the network link in part based on an objective function that uses the virtual link cost metric as a parameter.
