Subscriber Layer 1 Service Attributes

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.

Managed Access E-Line Service Implementation Agreement

Managed Access E-Line Service Implementation Agreement

This document defines a MAEL Service to allow a SP/SO to monitor services by utilizing a standard set of management capabilities, including SOAM FM, SOAM PM, and Latching Loop-back, in the MAEL Operator’s network. By leveraging management capabilities in the MAEL Operator’s network, a MAEL Service is intended to eliminate the need for the SP/SO to deploy hardware at the Subscriber’s location.

IP Service Attributes for Subscriber IP Services

IP Service Attributes for Subscriber IP Services

This document is the first MEF IP Services specification. It specifies Service Attributes for de-scribing Subscriber IP Services and is consistent with IETF STD 5 [77]. MEF Subscriber IP Services are IP Services described using the Service Attributes and includes private cloud access, Internet access, and managed VPN services. The specification does not discuss Internet peering between ISPs, it focuses on services for unicast traffic. Multicast traffic may covered in future revision. IPv4, IPv6 and “dual stack” services are supported.

Implementation Agreement – Transport Services for Mobile Networks

Implementation Agreement – Transport Services for Mobile Networks

This document identifies the requirements for MEF Ethernet Services and MEF External Interfaces (EIs such as User-Network Interface (UNI)s) for use in Mobile Backhaul networks based on MEF specifications. In addition, new interface and service attributes have been specified where needed. The services and requirements in this Implementation Agreement (IA) are based on the services defined in MEF 6.2 [3], MEF 33[27] and MEF 51 [30] as well as the attributes in MEF 10.3 [7], MEF 26.2 [24] and this IA. The aim is to be flexible to support a wide range of Ethernet service based mobile network deployments.

Network Resource Provisioning Interface Profile Specification

Network Resource Provisioning Interface Profile Specification

The Interface Profile Specification defines the requirements, use cases, realized classes, network resource interfaces and associated operations/parameters, state machines, and sequence diagrams that describe the behavior of the Presto NRP interface.

Network Resource Management - Information Model: Connectivity

Network Resource Management - Information Model: Connectivity

This specification describes the MEF Network Resource Management Information Model (NRM IM). Lifecycle Service Orchestration Reference Architecture (LSO RA, MEF 55 [10]) extends the tra-ditional MEF scope concerning Service Modeling, from a pure view “from outside the network” to cover a range of Operational, Orchestration, and Network Management behaviors, including SDN and NFV paradigms.
