Method Summary

Methods

Modifier and Type	Method and Description
Set<Path>	getPaths(NodeId src, NodeId dst) Returns the set of shortest path between the specified source and destination nodes, measuring link edge weight using hop count.
Set<Path>	getPaths(NodeId src, NodeId dst, LinkWeight weight) Returns the set of shortest paths between the specified source and destination nodes using the supplied link edge weight function.

Method Detail

getPaths

Set<Path> getPaths(NodeId src,
                 NodeId dst)

Returns the set of shortest path between the specified source and destination nodes, measuring link edge weight using hop count.

Parameters:

src - id of the source node

dst - if of the destination node

Returns:

set of paths

getPaths

Set<Path> getPaths(NodeId src,
                 NodeId dst,
                 LinkWeight weight)

Returns the set of shortest paths between the specified source and destination nodes using the supplied link edge weight function.

The LinkWeight.weight(com.hp.sdn.model.Link) may return a negative number to indicate that any path traversing that link should be considered as not viable.

Parameters:

src - id of the source node

dst - if of the destination node

weight - link edge weight function

Returns:

path or null if the path does not exist
