Networks extensively use link aggregation groups (LAGs) [802.1AX] and equal-cost multipaths (ECMPs) [RFC2991] as techniques for capacity scaling. For the problems addressed by this document, network traffic can be predominantly categorized into two traffic types: long-lived large flows and other flows. These other flows, which include long-lived small flows, short-lived small flows, and short- lived large flows, are referred to as "small flows" in this document. Long-lived large flows are simply referred to as "large flows".

Mechanisms for Optimizing Link Aggregation Group (LAG) and Equal-Cost Multipath (ECMP) Component Link Utilization in Networks
Demands on networking infrastructure are growing exponentially due to bandwidth-hungry applications such as rich media applications and inter-data-center communications. In this context, it is important to optimally use the bandwidth in wired networks that extensively use link aggregation groups and equal-cost multipaths as techniques for bandwidth scaling. This document explores some of the mechanisms useful for achieving this.
