2.4.2 IPE HEADER ENUMERATIONS AND MAPPINGS
Thcre oftcn are many IP data types that require encapsulation. The exact number of protocols depends on the mission and its requirements. These protocols are fully defined in other data standards. Thus the inlent here is to identify only auxiliary PDU tbrmats that are often used in support of IP. As a comparison, serial links between routers often carry the 16-bit Point- to-Point Protocol (PPP) protocol field, and the Ethernet PDUs carry a 16-bit Ethernet type field. In these cases, the enumerations of the protocols are defined by the Internet Assigned Numbers Authority (lANA) and the Institute of Electrical and Electronics Engineers (IEEE), respectively. The tables containing the enumerations then point to the standards that define the protocols themselves.
The alternative approach would have been to encapsulate a conventional link layer, such as Multiprotocol over Frame Relay, and use its method.s for identifying the auxiliary PDU formats.
Auxiliary protocols nominally identified at the Data Link Layer in support of IP include lPv4, lPv6, IP compressed header formats, the address resolution protocol for multi-access link layers, link layer control protocols including link metrics exchange and link health monitoring, various Data Link and Network Layer configuration protocols, and authentication protocols.
