It's a way to encode a piece of information with a type, a length followed by the information itself. Two points must be known : * The '''Value''' part may contents other '''TLVs'''. One can see '''TLVs''' as C structures, that can contain sub-structures. * The '''Length''' part may not give the '''Value''' length : it is called an indefinite '''Length'''. Whatever, in this - not so frequent - case, the '''Value''' must end with a specfic terminator. === Exemple === Lest's begin with a simple example, without too many explainations : [[Icon(TLVs.png)]]
