Constructor & Destructor Documentation

◆ PointToPointStarHelper()

ns3::PointToPointStarHelper::PointToPointStarHelper	(	uint32_t	numSpokes,
		PointToPointHelper	p2pHelper
	)

Create a PointToPointStarHelper in order to easily create star topologies using p2p links.

Parameters

numSpokes	the number of links attached to the hub node, creating a total of numSpokes + 1 nodes
p2pHelper	the link helper for p2p links, used to link nodes together
