¿µ¹®³»¿ë¿ä¾à | An Operator Ethernet Service is an Ethernet service provided by an Operator to another Operator or to an Ethernet Service Provider in a Carrier Ethernet Network (CEN) of multiple operators. These Service Attributes in this standard include: Operator Virtual Connection (OVC) Service Attributes, OVC End Point Service Attributes, External Network Network Interface (ENNI) Service Attributes and Operator User Network Interface (UNI) Service Attributes. Three General Operator Ethernet Services are defined as O-Line Service, O-LAN Service and O-Tree Service that are differentiated by the OVC Type. In addition, four specific Operator Ethernet Services are defined as Access E-Line Service, Access E-LAN Service, Transit E-Line Service, and Transit E-LAN service. The following provisions describe the changes in this revision as compared to TTAE.OT-03.0033.
- Two requirements related to the OVC Available MEG Level were deleted - [R4] and [D5] of TTAE.OT-03.0033. - Appendix A of TTAE.OT-03.0033 (Relationship of EVC and OVC Services) was deleted since Appendix H of MEF 26.2 (Comparison of Service Attribute Values) now addresses this relationship in more detail. - Appendix A in this document was changed from Appendix B of TTAE.OT-03.0033 (Practical Examples of Ethernet Services). - Appendix D in this document was updated from Appendix C of TTAE.OT-03.0033 (Comparing Access Service Attributes). - The SOAM Use Case in Appendix B of this document is significantly changed from Appendix D of TTAE.OT-03.0033. - MEF 26.2 introduced 13 new service attributes, etc. |
