Abstract
In a cluster environment, nodes participating in the cluster may generate packets with the same source IP to the same destination IP. If those packets get fragmented down stream, then reassembling this packets depends on the source IP, destination IP, protocol and the IP identifier field (IPID) of the IP packet. As the source IP, destination IP and protocol may be fixed, the IPID generation is coordinated across the nodes to support reassembly down stream and avoid tuple collision. The IPID space may be equally split among the nodes in the cluster. Each node generates IPID within its range to avoid a collision with an IPID generated from another node.
