Performance management techniques have been gaining traction with those looking for OAM capabilities on par with the legacy networks that Ethernet replaces. Along with Delay and Loss measurement, throughput measurements have become an important component of the Performance management toolkit.

The slides provide Ethernet performance management in detail, beginning with an overview of the technology, a comparison with what else is available today followed by a discussion of the latest Ethernet performance management features planned for the various Cisco IOS XR and Cisco IOS XE platforms.
