A One-Path Congestion Metric for IPPM
draft-dang-ippm-congestion-03
Abstract
This memo defines a metric for one path congestion across Internet
paths. The traditional mode evaluates network congestion based on
the bandwidth utilization of the link. However, there is a lack of
E2E path congestion that is truly service oriented. So A Path
Congestion Metric is required.

1. Introduction
As we know, the current network has been already being in load
balancing mode, however it is partially congested. To solve the
problem of unbalanced network load[draft-liu-ican], Congestion of
paths requires an assessment metric. The traditional mode evaluates
network congestion based on the bandwidth utilization of the link.
However, there is a lack of E2E path congestion that is truly service
oriented.
So this memo defines a metric for a path congestion across Internet
