Detailed Description

The RouteManager provides a unified interface to adding and deleting routes between nodes in the simulated topology.

The class is essentially an implementation of a simple heirarchical database of all routes between a node and other possible destinations. Output from a routing process can store the computed routes in this database.

Member Function Documentation

void sim::RouteManager::addRoute (  u_int  src, u_int  dest, u_int  rtSize, int *  rt )

Add a route to the specified node's database. Parameters: src  The specified source node to which the route will be added dest  The destination node rtSize  The size of routes in terms of the number of nodes involved and not the number of hops. Hence rtSize = hop_count + 1 rt  The route

int* sim::RouteManager::getRoute (  u_int  src, u_int  dest )

Search the route tables for any existing route between the source and destination. Parameters: src  The source node dest  The destination node Returns: A valid route. NULL in case of no route or error.

u_int sim::RouteManager::getRouteSize (  u_int  src, u_int  dest )

Get the route size for the existing route between the source and destination. Parameters: src  The source node dest  The destination node Returns: The route size in the number of hops. (0 if no route exists)

void sim::RouteManager::parseRouteFile (  RouteManager *  rm, std::string  filename )  [static]

Parse an input route file and populate the route manager. An example format of the route file is as follows (For example, a route between 0 and 8 between 5 and 3 0 8 4 4 0 5 3 8 Parameters: rm  A pointer an already created RouteManager object filename  THe input route file
