Subscriber Ethernet Service Attributes
This document describes Service Attributes for Subscriber Ethernet Services provided to an Ethernet Subscriber by an Ethernet Service Provider. The Service Attributes describe behaviors observable at an Ethernet User Network Interface and from Ethernet User Network Interface to Ethernet User Network Interface. In addition, a framework for defining specific instances of Subscriber Ethernet Services is described. Finally, extensive examples and explanatory material is included in appendices.
Layer 2 Control Protocols in Ethernet Services
This document specifies the Service Attributes and requirements for handling Layer 2 Control Protocol (L2CP) Frames for Ethernet Services and replaces MEF 45.
Operator Ethernet Service Definition
51.1 specifies Operator Ethernet Services based on the Service Attributes defined in MEF 26.2. The key service constructs are the Operator Virtual Connection (OVC) and the OVC End Points at the External Interfaces (EIs) – the External Network Network Interface (ENNI) and the User Network Interface (UNI).
MEF 57.1 - Ethernet Ordering Technical Standard - Business Requirements and Use Cases
This document represents the cumulative work between MEF and ATIS Ordering and Billing Forum (OBF) to identify the common ordering attributes and processes needed to support inter-carrier Product Ordering of Ethernet Services worldwide. This document supports the requirements defined in the MEF Lifecycle Service Orchestration (LSO) Reference Architecture and Framework (MEF 55, “LSO RA”) requirements for Ordering over the Sonata interface (Service Provider <-> Partner interactions). Information contained within this document will be utilized by both Buyer and Seller ordering systems for the development of automated API systems.
Implementation Agreement – Transport Services for Mobile Networks
This document specifies the Service Attributes that need to be agreed between a Service Provider and a Subscriber for IP Services, including IP VPNs, cloud access and Internet access. It further specifies the Service Attributes that need to be agreed between a Service Provider and an Operator when part of an end-to-end IP Service needs to be implemented by a partner Operator. Some key concepts are introduced, including IP UNIs, IP ENNIs, IP Virtual Connections, IP Virtual Connection End Points, IP UNI Access Links and IP ENNI Links. Specific Service Attributes and corresponding behavioral requirements are defined for each of these entities. These include support for assured services, e.g. multiple Classes of Service, performance objectives specified in a Service Level Specification, and Bandwidth Profiles.
Operator Ethernet Service Definitions
This document specifies Operator Ethernet Services based on the Service Attributes defined in MEF 26.2. The key service constructs are the Operator Virtual Connection (OVC) and the OVC End Points at the External Interfaces (EIs) – the External Network Network Interface (ENNI) and the User Network Interface (UNI). Per MEF 26.2, at least one OVC End Point is at an ENNI. Three General Operator Ethernet Services are defined, based on OVC Type. In addition, two E-Access and two E-Transit services are defined, based on OVC Type and the EIs involved. This document supersedes and replaces MEF 51, which is based on MEF 26.1 Service Attributes, and MEF 33.
Subscriber Layer 1 Service Attributes
The attributes of a Subscriber Layer 1 Service observable at a Layer 1 User Network Interface (L1 UNI) and from a L1 UNI to a L1 UNI are defined. In addition, a framework for defining specific instances of a Subscriber Layer 1 Service is described.
Commercial Affecting Attributes
MEF 74 specifies the Commercial Affecting Attributes that need to be agreed between a Service Provider and a Subscriber and between a Service Provider and a Partner for Commercial activity related to MEF Defined Services.
MEFCore Model (MCM)
MEF 78 defines the MEF Core Information Model (MCM), which is an information model describing the base set of object definitions and relationships supporting the concepts defined in the MEF Lifecycle Service Orchestration (LSO) Reference Architecture (RA).
