Abstract
A device includes a security process unit (SPU) associated with a logical ring of SPUs. The SPU receives a packet with an address associated with a malicious source, and creates, based on the packet, an entry in a data structure associated with the SPU. The entry includes information associated with the packet. The SPU provides an install message to a next SPU in the logical ring. The install message instructs the next SPU to create the entry in another data structure, and forward the install message to another SPU. The SPU receives the install message from a last SPU, and sets a state of the entry to active in the data structure based on receiving the install message from the last SPU. The SPU performs a particular action on another packet, associated with the malicious source, based on the setting the state of the entry to active.
