Best source for the information on Multi-CoS is the specifications themselves, which you can find published here “http://metroethernetforum.org/page_loader.php?p_id=29″.

I assume you are referring to Carrier Ethernet 2.0 (CE 2.0) which was launched earlier this year by the Metro Ethernet Forum. CE 2.0 is essentially a branding of related specifications over the course of the last number of years to help the industry understand how Ethernet as a carrier service has evolved. One of those evolutions is the support for multiple classes of service which is critical for business services (aka, bronze, silver, gold) as well as making better use of any data service link such as those used in mobile backhaul where you have a combination of voice traffic, management and synchronization traffic, data and high-value video content. The implementation agreement within MEF 23.1 is really about defining a standard way for operators to align their CoS to promote interoperability in support of off-net access, wholesale mobile backhaul and other multi-operator services so that they can get to market faster. It also helps the Ethernet exchange market on a similar basis. An operator would merely have to use the defined labels (or potentially a subset/superset with appropriate mapping) knowing that on the other side of the ENNI – the labeling would be managed and understood the same way.

The other items of note are the new performance metrics (Mean Delay and Delay Range) along with the 4 performance tiers with CoS performance objectives and that’s where InfoVista’s composite KPIs help by enabling high-level KQIs based on the CPO, which can then be used to drill down to the individual metrics, associated metrics such as traffic usage and resource health and finally manage adherence to the CPO.

I hope that addresses your comment sufficiently.

In addition, if you’d like to learn more about how application-aware premium reporting can help service providers offer differentiated IP-VPN services, gain new customers and fight the IP-VPN revenue crunch, be sure to read more about InfoVista’s solutions . This downloadable PDF delves into how service providers can develop a multi-tiered VPN reporting service portfolio as a mechanism to generate new revenue streams and differentiate service offerings.
All the best!

I have been reading/expericing about the operator’s focus on Service Assurance based on the collection ,correlation,Analysis of data but from what i understand one also needs to understand that what kind of device/application/OS is being used to access the network which could be a considerable factor when it comes of QOE. So i believe end-to-end view must include what device is being used …
