Abstract
Methods, systems, and computer program products are provided for efficient packet replication. In an embodiment, a packet is stored as a linked list of at least one page. Replicating the packet comprises creating a new header page and linking it to the first page of the linked list. Each replica packet may be transmitted independently and concurrently. In an embodiment where packets are stored in queues, each replica packet may be dequeued for transmission independently and concurrently. After all references to a page have been transmitted (or dequeued), the page may be freed.
