TCP segmentation offload
Abbreviated as TSO, TCP segmentation offload
is used to reduce the CPU
overhead of TCP/IP
on fast networks. TSO breaks down large groups of data
sent over a network
into smaller segments
that pass through all the network elements between the source and destination. This type of offload relies on the network interface controller
(NIC) to segment the data and then add the TCP, IP and data link layer protocol headers to each segment. The NIC must support TSO. TSO is also called large segment offload (LSO).
