Internet Protocol (IP) Transport Interface Specifications

The Internet Protocol (IP) Transport stack uses the same set of interface specifications which are used by OSI. This permits Internet Protocol (IP) Transport components and ISO components to be used interchangeably for transport.

Following is a table listing the pertinent Internet Protocol (IP) Transport interfaces and the primary reference, specifications document and header files at each level:
