◆ Install() [2/2]

void ns3::ndn::GlobalRoutingHelper::Install ( const NodeContainer &  nodes)

Install GlobalRouter interface on nodes.

Note that GlobalRouter will also be installed on all connected nodes and channels

Parameters
nodesNodeContainer to install GlobalRouter interface

◆ AddOrigin() [1/2]

void ns3::ndn::GlobalRoutingHelper::AddOrigin ( const std::string &  prefix,
Ptr< Node >  node 
)

Add ‘prefix’ as origin on ‘node’.

Parameters
prefixPrefix that is originated by node, e.g., node is a producer for this prefix
nodePointer to a node

◆ AddOrigins()

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

Add ‘prefix’ as origin on all ‘nodes’.

Parameters
prefixPrefix that is originated by nodes
nodesNodeContainer

References AddOrigin().

◆ AddOrigin() [2/2]

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

Add ‘prefix’ as origin on node ‘nodeName’.

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

References AddOrigin().

◆ 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.

Refer to the implementation for more details.

Note that this method is highly experimental and should be used with caution (very time consuming).
