Is the data part also send in Network Byte Order?

[M K Saravanan <mksarav@xxxxxxxxxxxxxxxxx>]

hi,

While sending integers in the header like IP addr, etc.., we are sending it in
Network Byte Order.  What about data?  Do we have to send data - also in  NBO?
If not, how the other end will know whether it is small/big endian?
