3. LINK LAYER

Although [INTRO:1] covers Link Layer standards (IP over various link layers, ARP, etc.), this document anticipates that Link-Layer material will be covered in a separate Link Layer Requirements document. A Link-Layer Requirements document would be applicable to both hosts and routers. Thus, this document will not obsolete the parts of [INTRO:1] that deal with link-layer issues.
