Where to Split Header and Data

The following are the only valid places where a header-data split provider can split an Ethernet frame:

• Beginning of upper-layer-protocol header.

• Beginning of UDP payload.

• Beginning of TCP payload.

Note  These requirements apply only to header-data split providers. For more information about splitting frames in cases where header-data split is not used, see Cases Where Header-Data Split Is Not Used.

The following figure shows the major parts of the Ethernet frame and the valid split locations.
