Hi Hui and all, When I went through the documents of IETF#96,I noticed that this draft has raised a interesting requirement in China Mobile of E2E deployment interface to a multiple VPNs composed infrastructure, such as L2+L3 network. So the interface could make the service fulfillment and management more easy. Is my understanding right?
I do believe this interface and its model are indeed helpful for operators to simplify operations and management. And I still have some questions need to be discussed and aligned with you and experts in email thread. 1.While referring to another draft at same meeting <<service model explained>> (https://tools.ietf.org/id/draft-wu-opsawg-service-model-explained-03.txt), I believe the above E2E deployment interface should be position between service orchestration and network orchestration(Figure 3). That mean it’s a internal interface in one operator and it acts not only to implement the customer facing model (i.e. L3SM),but also to maintain, monitor and diagnose the end to end PE-based VPN services crossing multiple technologies deployed network. Is it right? and should this interface need to support VPN service which maybe cross multiple operators? 2.Actually I’m new guy in IETF, so I’m not sure if there are existing works in IETF which could instruct or modeling the interface/E2E-view to manage a multiple technologies composed network, which I believe very common in operator’s deployment while still need to provide simple E2E service experience to their customers. Maybe we can improve something here. So if experts here have more background, please help me. Thanks. 3.As I understand this interface/model should be internal in operators, so I’m not sure if there any other operators are interested it and need a IETF RFC? Thanks.
