1 Introduction
1.1 Functional Description
Mellanox Ethernet adapters utilizing IBTA RoCE technology provide efficient RDMA services,
delivering high performance to bandwidth and latency sensitive applications. Applications utiliz-
ing TCP/UDP/IP transport can achieve industry-leading throughput over 10 or 40GbE. The hard-
ware-based stateless offload and flow steering engines in Mellanox adapters reduce the CPU
overhead of IP packet transport, freeing more processor cycles to work on the application. Sock-
ets acceleration software further increases performance for latency sensitive applications. This
