Abstract

In certain networks, such as, but not limited to, financial information networks (e.g., stock market data providers), network performance information (e.g., link propagation delay) is becoming as critical to data path selection as other metrics.

             OSPF Traffic Engineering (TE) Metric Extensions

Abstract

   In certain networks, such as, but not limited to, financial    information networks (e.g., stock market data providers), network    performance information (e.g., link propagation delay) is becoming    critical to data path selection.

   This document describes common extensions to RFC 3630 "Traffic    Engineering (TE) Extensions to OSPF Version 2" and RFC 5329 "Traffic    Engineering Extensions to OSPF Version 3" to enable network    performance information to be distributed in a scalable fashion.  The    information distributed using OSPF TE Metric Extensions can then be    used to make path selection decisions based on network performance.

   Note that this document only covers the mechanisms by which network    performance information is distributed.  The mechanisms for measuring    network performance information or using that information, once    distributed, are outside the scope of this document.
