Member Function Documentation

◆ CheckPath()

void GlobalRoutingProtocolTestCase::CheckPath	(	std::vector< Ptr< Node > >	pathNodes,
		std::vector< Ipv4Address >	path )

private

Checks the Path taken by packets by calling RouteInput() and RouteOutput() APIs of GlobalRoutingProtocol.

This mimics how Ipv4L3Protocol calls these APIs.

Parameters

pathNodes	Vector of nodes in the path. This includes the source node,Intermediate nextHop nodes and the destination node.
path	Vector of Ipv4Addresses in the path. This includes the source egress IpAddress, destination ingress IpAddress and intermediate nextHop Node's ingress Ipaddress that we need to check.It does not include the egress addresses for intermediate nodes.

Here is the call graph for this function:

◆ DoSetup()

void GlobalRoutingProtocolTestCase::DoSetup ( )

overrideprivatevirtual

Implementation to do any local setup required for this TestCase.

Subclasses should override this method to perform any costly per-test setup before DoRun is invoked.

This test case is designed to test the overall functionality of the GlobalRoutingProtocol. It tests the calls to the GlobalRoutingProtocol's RouteOutput() and RouteInput() APIs. It mimics how Ipv4L3Protocol calls these APIs. The topology covers most of the cases that are expected to be handled by the GlobalRoutingProtocol.

Reimplemented from ns3::TestCase.
