A packet-forwarding network node can process a programmable packet based on a reputation value for a name prefix to perform a customized operation on a local resource. The programmable packet can include a name prefix, and a header comprising reputation criteria for the packet's name prefix and one or more resource fields. A resource field can include instructions that perform an operation on a corresponding resource of the network node. When the network node receives the programmable packet, the node determines a reputation value for the name prefix at the local node, and compares this reputation value to the packet's reputation criteria. If the reputation value for the name prefix at the local node satisfies the reputation criteria, the node proceeds to execute the one or more instructions of the respective resource field to perform the operation on the corresponding resource.
