A core mechanism in every forwarding strategy is the decision of whether to retransmit an
unsatisfied Interest or to wait for an application retransmission. While some applications
request control of all retransmissions, others rely on the assumption that the strategy will
retransmit an Interest when it is not satisfied. Although an application can select the
forwarding strategy used in the local host, it cannot guarantee that the same strategy will be
selected in other nodes in the network, especially in shared resource environments. In this …

The strategy layer is an important architectural component in both Content-Centric
Networking (CCN) and Named Data Networking (NDN). This component introduces a new
forwarding model that allows an application to configure its namespace with a forwarding
strategy. A core mechanism in every forwarding strategy is the decision of whether to
retransmit an unsatisfied Interest or to wait for an application retransmission. While some
applications request control of all retransmissions, others rely on the assumption that the …
