Detailed Description

Dispatch header helper.

This class only purpose is to interpret the Dispatch header into its correct type.

The dispatch type is defined by a zero bit as the first bit and a one bit as the second bit.

◆ NhcDispatch_e

enum ns3::SixLowPanDispatch::NhcDispatch_e

Dispatch values for Next Header compression.

The dispatch values reflect the dispatch use, since some dispatch bits carry actual header compression bits.
