Abstract
One embodiment provides a system that facilitates a content requesting device to handle a potential timeout event. During operation, the system receives, by a content producing device, a packet that corresponds to a first Interest message from a content requesting device, where the first Interest includes a name. Responsive to determining that additional time is required to generate a matching Content Object for the first Interest, the system generates a notification message which indicates a time period after which a second Interest is to be sent out by the content requesting device. The name for the second Interest can be the same as the name for the first Interest or a new name as indicated in the notification message. The system transmits the notification message to the content requesting device, thereby facilitating the content requesting device to handle a potential timeout event.
