Application-layer routing program

Virtual-Routing

Application-layer routing program, using UDP

Introduction

• self-organized routing

  • Select a virtual topo for members’ computers
  • Build virtual connection between computers according to the virtual topo;
  • Each computer acts as both client and router.
  • Each computer exchanges and updates routing table periodically.
  • A computer can send message to other computers

• centralized routing

  • Like the above self-organized routing
  • Controller determines and distributes routing policy (routing table) to each member

• can choose different topo(the 2 above) & different routing algorithms

  • LS
  • DV

Coding Doc [Un-completed]

All PC Nodes will run as a Node. Before a Node.Start(), the RouteAlgoType and ActionMode MUST be specified. OR it will panic out and exit.

Node n;
n.SetRouteAlgoType(RouteAlgoType::LS);
n.SetActionMode(ActionMode::NORMAL);
n.Start();

Classes Hierarchy

• Args [Singleton] : store the args
• Node : Abstract of the Nodes in routing
• RouteAlgo : virtual base class for the Routing-Algorithm
  • RouteLS : Link-State Algorithm
  • RouteDV : Distance-Vector Algorithm

The RouteLS or RouteDV class will be initialized automatically inside a Node as soon as SetRouteAlgoType() is called. So DON'T init a RouteAlgo manually.
