TCP segmentation Offload

When abbreviated it is written as TSO, TCP segmentation is adopted in reducing the CPU overhead of TCP/IP on the fast networks. This protocol breaks down the large groups of data into smaller parts which passes via all the network elements between the source and destination.
This kind of offload depends upon the network interface controller to divide the data and then add the TCP, IP and data link layer protocol headers to every part.
The TSO is also known as LSO (large segment offload).
