start | an iterator which points to where the header should read from. |
This method is used by Packet::RemoveHeader to re-create a header from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this header in real networks.
Note that data is not actually removed from the buffer to which the iterator points. Both Packet::RemoveHeader() and Packet::PeekHeader() call Deserialize(), but only the RemoveHeader() has additional statements to remove the header bytes from the underlying buffer and associated metadata.

Get the most derived TypeId for this Object.
This method is typically implemented by ns3::Object::GetInstanceTypeId but some classes which derive from ns3::ObjectBase directly have to implement it themselves.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. This method should return the number of bytes which are needed to store the full header data by Serialize.

os | output stream This method is used by Packet::Print to print the content of a header as ascii data to a c++ output stream. Although the header is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace. i.e.: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5 |
