Abstract
In one embodiment, a device in a network receives an interest request for one or more pieces of content data available in the network. The interest request specifies the one or more pieces of content data via one or more bits sets in a content request bitmap of the interest request, each bit of the content request bitmap being associated with a different piece of content data. The device compares the content request bitmap to a content availability bitmap in a forwarding information base (FIB) of the device that is associated with a particular interface of the device and each bit of the content availability bitmap indicates whether a particular piece of content data is available via the particular interface. The device forwards the interest request via the particular interface, based on the comparison between the content request bitmap and the content availability bitmap in the FIB of the device.
