Abstract
The present application is directed towards systems and methods for handling fragmented packets in a cluster environment. Fragments received by the cluster may be hashed based on a tuple of network layer information, such as source and destination IP addresses. The tuple of network layer information may be used to identify a device of the cluster as a 'fragment owner' or node responsible for assembling the fragments of the packet. The fragment may be transmitted or steered to the fragment owner for accumulation and assembly. Once all fragments of the packet have been received by the fragment owner, the packet may be assembled and a second hash may be calculated based on a four-tuple of network and transport layer information, such as source and destination IP addresses and port numbers. The packet may then be steered or transmitted to the 'packet owner' or node responsible for processing the packet.
