Abstract
A method, system, and/or computer program product steers Internet Protocol (IP) packet fragments. A switch receives a first IP packet fragment that contains a 3-tuple in its header. In response to determining that the first IP packet fragment is not a lead packet fragment in the series of IP packet fragments, the first IP packet fragment is pushed onto a data stack. The switch subsequently receives a second IP packet fragment that contains a 5-tuple, which includes the 3-tuple from the first IP packet fragment plus a source port and destination port used by the second IP packet fragment. The 3-tuple is mapped to the 5-tuple in a fragmentation table, thus enabling both the first IP packet fragment and the second IP packet fragment to be steered to the destination port to which the second IP packet fragment is being sent.
