In an information-centric networking (ICN) environment, an interest may be dropped by a network for any number of reasons. However, if an interest is lost then the corresponding data cannot be received, thereby reducing the performance of a network. Techniques are presented herein that make ICN interests more resilient to potential losses by adding certain state information into an interest payload. That state information may be used to keep track of the previous interests that have been sent by a forwarder face for a specific name. To encode the sequence numbers of the interests that have been previously sent, a first aspect of the presented techniques employs a list of sequence numbers while a second aspect of the presented techniques employs a bitmap. The presented techniques may be used to reduce the possibility that interests are not dropped during transit when using ICN.
