A Case for Stateful Forwarding Plane

In Named Data Networking (NDN), packets carry data names instead of source or destination addresses. This change of paradigm leads to a new network forwarding plane: data consumers send Interest packets, routers forward them and maintain the state of all pending Interests, which is then used to guide Data packets back to the consumers. Maintaining the pending Interest state, together with the two-way Interest and Data exchange, enables NDN routers' forwarding process to quickly detect network problems and retry multiple alternative paths.
