Today’s data centers depend on the mul-
tiprocessing, high performance capability
of servers to increase system throughput,
responsiveness, and reliability through
the introduction of additional hardware
threads, CPUs, or cores. But in a multi-
processing environment, it is essential to
ensure a coordinated affinity of protocol
processing and network applications
on the same target cores. This affinity
significantly reduces contention for shared
resources, minimizes software synchro-
nization overheads between cores, and
enhances cache efficiency.

Receive Side Scaling (RSS) resolves the
single-processor bottleneck by enabling
the receive side network load from a net-
work adapter to be shared across multiple
cores. RSS enables packet receive-pro-
cessing to scale with the number of avail-
able cores. However, RSS has a limitation.
