  Compact Alternate Marking Methods for Passive Performance Monitoring
          draft-mizrahi-ippm-multiplexed-alternate-marking-02

Abstract

   This memo introduces new alternate marking methods that require a
   compact overhead of either a single bit per packet, or zero bits per
   packet.  This memo also presents a summary of alternate marking
   methods, and discusses the tradeoffs among them.  The target audience
   of this document is network protocol designers; this document is
   intended to help protocol designers choose the best alternate marking
   method(s) based on the protocol's constraints and requirements.

Status of This Memo
