Field Detail

orbPort

private int orbPort

The port of the ORB daemon on the PlanetLab nodes. The orbd is listening on this port for incoming RMI calls. PlanetLabClient is executing these RPC calls. Note that you need to bootstrap a node to make a change take effect.

sshPort

private int sshPort

The port on which the launched sshd of the PlanetLab nodes should listen for incoming connections. Note that you need to bootstrap a node to make a change take effect.

testFilePath

private java.lang.String testFilePath

This path defines the file which is transferred to a node to measure the bandwidth to this node.

testFileSize

private int testFileSize

the size of the testFile in Bytes

bwLimitForSingleNodeGroup

private double bwLimitForSingleNodeGroup

The minimum required bandwidth to the nodes of a group to form a group with them
