Abstract
While each node in a cluster of nodes sources connections with the same IP if each node allocates a port on this IP independently, there may be port clashes. Also, the return traffic is not guaranteed to hit the originating node. These issues are addressed by allocating a port in such a way that the response traffic hashes back to the originating node. A good hash is chosen such that the ports are equally divided among the nodes. When a node leaves, the other nodes take over the port range used by this node. When a node joins, the node takes back its share of ports.
