Network Working Group S. Baillargeon INTERNET-DRAFT C. Flinta Intended Status: Informational A. Johnsson Expires: December 31, 2012 S. Ekelin Ericsson June 29, 2012 Ericsson TWAMP Value-Added Octets draft-ietf-ippm-twamp-value-added-octets-04.txt Abstract This memo describes an extension to the TWAMP test protocol for identifying and managing packet trains, which enables measuring capacity metrics like the available path capacity, tight section capacity and UDP delivery rate in the forward and reverse path directions. This memo contains the description of a working prototype. It does not represent a consensus of the IETF community. The IETF community is currently working on the problem statement and has not reached consensus on the preferred method for measuring capacity metrics. Status of this Memo This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF). Note that other groups may also distribute working documents as Internet-Drafts. The list of current Internet- Drafts is at http://datatracker.ietf.org/drafts/current/. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." This Internet-Draft will expire on December 31, 2012. Baillargeon, et al.
