Mario, I'm not a technical expert (or any other kind), but I can take a stab at this. If one were to look at the construct of certain header records (IP, TCP, ICMP, etc), there are fields which can contain certain values. Some of these fields define the set of permissible values from which the appropriate value is selected/chosen. Many protocol header records include a space for the inclusion of options, each of which is assigned a particular value for uniqueness. For example, in the IP header, there is a IP Version field. There are also such things as Type of Service fields, option fields, protocol fields, traffic class fields (in IPv6), etc. I hope this helps.
