Compact Alternate Marking Methods for Passive and Hybrid Performance
Monitoring
draft-mizrahi-ippm-compact-alternate-marking-05
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.
