AddOrigins()

void ns3::ndn::GlobalRoutingHelper::AddOrigins	(	const std::string &	prefix,
		const NodeContainer &	nodes
	)

Add `prefix' as origin on all `nodes'.

Parameters

prefix	Prefix that is originated by nodes
nodes	NodeContainer

AddOrigin() [2/2]

void ns3::ndn::GlobalRoutingHelper::AddOrigin	(	const std::string &	prefix,
		const std::string &	nodeName
	)

Add `prefix' as origin on node `nodeName'.

Parameters

prefix	Prefix that is originated by node, e.g., node is a producer for this prefix
nodeName	Name of the node that is associated with Ptr<Node> using ns3::Names

CalculateRoutes()

void ns3::ndn::GlobalRoutingHelper::CalculateRoutes ( )

static

Calculate for every node shortest path trees and install routes to all prefix origins.

Definition at line 218 of file ndn-global-routing-helper.cpp.

References ns3::ndn::FibHelper::AddRoute(), and ns3::ndn::L3Protocol::getForwarder().

CalculateLfidRoutes()

void ns3::ndn::GlobalRoutingHelper::CalculateLfidRoutes ( )

static

Calculates a set of loop-free multipath routes.

CalculateAllPossibleRoutes()

void ns3::ndn::GlobalRoutingHelper::CalculateAllPossibleRoutes ( )

static

Calculate all possible next-hop independent alternative routes.
