- A Technical Overview
- Juniper Networks
As Ethernet emerged from being a LAN technology into a carrier-class technology, Ethernet OAM has been developed to ease the operations, administration, and maintenance of complex Ethernet service provider networks and lower their operational expenditures. This paper gives a technical overview of Ethernet OAM. It discusses link fault management, connectivity fault management, and performance monitoring. In the use case section, it discusses cases in which Ethernet OAM is deployed and how Ethernet OAM adds value to the deployment of related technologies. The technologies discussed are MPLS fast reroute, bidirectional detection forwarding, Layer 2 VPNs, virtual private LAN service, and Ethernet ring protection switching.

I really, really like this paper.
As Ethernet has become an integral part of WAN services instead of just the LAN infrastructure, the ability to offer effective OA&M is critical to network reliability. And it's important to both of our major communities. For service providers, it provides a guide to maintaining Ethernet services on the WAN. For some enterprises, it likewise provides a "what to look for" guide for your own network. But more importantly for all enterprises, it gives you a view of the type of architecture that you should be expecting from your service provider(s).
A "must read" that truly appeals to my "inner geek" in the extreme level of detail.
