Query: HyperNAT: Scaling Up Network AddressTranslation with SmartNICs for
  Clouds   Network address translation (NAT) is a basic functionality in cloud gateways.
With the increasing traffic volume and number of flows introduced by the cloud
tenants, the NAT gateway needs to be implemented on a cluster of servers. We
propose to scale up the gateway servers, which could reduce the number of
servers so as to reduce the capital expense and operation expense. We design
HyperNAT, which leverages smartNICs to improve the server's processing
capacity. In HyperNAT, the NAT functionality is distributed on multiple NICs,
and the flow space is divided and assigned accordingly. HyperNAT overcomes the
challenge that the packets in two directions of one connection need to be
processed by the same NAT rule (named two-direction consistency, TDC) by
cloning the rule to both data paths of the two directions. Our implementation
and evaluation of HyperNAT show that HyperNAT could scale up cloud gateway
effectively with low overhead.
