Hi Myagaa,
Customer Facing Service(CFS) Spec describes the Service as understood by the customer.
<o:p></o:p>CFS Spec characteristics comproises of:<o:p></o:p>
· Product characteristics needed to establish what needs to be delivered/fulfilled. e.g., Bandwidth of Internet Service, number of Static IP.<o:p></o:p>
· Resources assigned to Customer. e.g., Static IPs assigned to Customer. <o:p></o:p>Configurations the customer might be able to do to use the Service per their needs. e.g., BGP
CFS is made up of one or more RFS.
Resource Facing Service(RFS) Spec describes the Service as in the network. RFS Spec abstracts/hides the technology details that are not relevant to customer. Reuse of the model and processes is also one of the consideration while modelling the RFS Spec, with-out compromising on the RFS Spec still depicting a Service.<o:p></o:p>
RFS Spec characteristics comprises:<o:p></o:p>
· CFS characteristics to be provisioned/configured in the network. e.g., Bandwidth of Internet Service, Static IPs to be provisioned in the network, and BGP configuration. Any technical attributes needed to manage the resources and services in the network. e.g., Circuit ID<o:p></o:p>

Subject: CFS vs RFS
Hi,
I have read some marerials like gb922 product, service, and ig1228 use cases. So, what I understood about CFS, it is just abstraction layer that covers multiple RFSs in order to give intangible products. So, I need to confirm my understanding about it. RFSs are real service applications, cfs is just abstract expression to be given to customer. Is it right? Or can cfs be real service?
