Technical Summary This document provides advice to the designers of digital communication equipment, link-layer protocols and packet-switched subnetworks (collectively referred to as subnetworks) who wish to support the Internet protocols but who may be unfamiliar with the Internet architecture and the implications of their design choices on the performance and efficiency of the Internet. The document includes among its topics: recommendations about maximum transmission units and their tradeoffs for slow subnetwork types; issues with connection-oriented subnetwork designs; recommendations for multicast capabilities for links; recommendations for reliability, error control, and their interactions with TCP, as the major reliable transport protocol in the Internet; recommendations about use of compression; recommendations about avoidance of significant packet reordering; and recommendations that both link-level and end-to-end security be used for their particular benefits. This document represents a consensus of the members of the IETF Performance Implications of Link Characteristics (PILC) working group. Working Group Summary The working group strongly supported advancement of this document. Protocol Quality The document was reviewed for the IESG by Mark Allman and Allison Mankin.
