RE: [EFM] OAM loop back / echo server function


If the management is "in band" then I can not use this technology for 
anything other than "best effort" type services.  As a service provider, I 
am in need of something that I can support "Private Line" type services for 
businesses.  "Private Line" is still the dominant data communications 
service  requested by business customers of many service providers, to 
build the secure enterprise networks.  Business "Private Line" is the 
highest margin service in the suite of services that can be provided.

I am hoping that with EFM, edge link infrastructure can be built that will 
provide remote physical layer operations support that will allow legacy as 
well as legacy free service providers the ability to support Ethernet 
service customers.  Without EFM, service providers are having to put 
expensive multi-layer systems with separate management communications 
directly on each customer primese.  While this may not be very expensive 
today, it will not scale very well, and continuing competition and economic 
pressures will soon make that unprofitable.

Thank you,
Roy Bynum
