MEF is closer to connecting any network to any network with the publication of standards that ensure different network components can talk easily to each other.
MEF published two new specifications advancing the orchestration of MEF 3.0 connectivity services over multiple network technology domains. The new standards – the Network Resource Management: Information Model (MEF 59) and Network Resource Provisioning (NRP): Interface Profile Specification (MEF 60) – were developed within MEF’s LSO (lifecycle service orchestration) reference architecture. The specifications are important steps toward accelerating the delivery of agile, assured, and orchestrated services over automated networks powered by LSO, SDN, and NFV.
“MEF members have been working diligently to develop and demonstrate model-driven ‘north-south’ intra-provider LSO APIs and ‘east-west’ inter-provider LSO APIs that are required to orchestrate MEF 3.0 services*,” said Nan Chen, President, MEF.
“The new specifications enable us to define the critical LSO Presto NRP API for orchestrating services over a mix of underlying network technologies. We thank the LSO project teams for their diligent work and look forward to also sharing more good news related to interprovider orchestration in the coming months.”
MEF’s LSO reference architecture guides agile development of the models, processes, tools, and APIs that will enable orchestration of MEF 3.0 services (e.g., Layer 1, Carrier Ethernet, IP, and SD-WAN) across multiple providers and over multiple network technology domains. The LSO reference architecture extends the traditional MEF scope concerning service modelling to cover a range of operational, orchestration, and network management behaviours, including SDN and NFV paradigms.
In support of the LSO reference architecture, MEF 59 defines the information model to facilitate the orchestration of Carrier Ethernet connectivity services through WAN SDN controllers, optical transport network (OTN) subnetwork managers, and legacy network management systems. The MEF NRM model is specified in the Papyrus unified modelling language (UML) and is based on current and developing best network management solutions by the ITU Telecommunication Standardization Sector (ITU-T), Open Networking Foundation (ONF), and TM Forum to allow wider interoperability across multivendor and multi-technology platforms. This approach also facilitates upcoming work on operations, administration and maintenance (OAM) and OTN.
Along with the LSO reference architecture, the MEF network resource management (NRM) serves as a basis for the new MEF 60 specification and thus supports the LSO Presto interface.
“MEF is playing a leading role to deliver the seamless management of services and resources in a multi-carrier, multivendor, multi-technology environment,” said Andrea Mazzini, Editor of MEF 59 and Senior Systems Engineer, Nokia. “Interoperable network management models are a fundamental part of the picture and play a key role in the standardisation of agile, assured, and orchestrated end-to-end connectivity.”
CenturyLink, Ciena, Cisco, Coriant, Ericsson, Huawei, Infinera, NEC, and RAD joined Nokia in contributing to MEF 59.
MEF members have also been working to create a suite of standardised LSO Presto APIs defined in MEF Interface Profile Specifications (IPSs) dealing with network resource provisioning, performance monitoring, and other functions over various technology domains. MEF 60 is an LSO Presto NRP IPS.
MEF 60 provides an abstracted, intent-based solution for activation of and the topology retrieval of network resources in support of MEF-defined services. The specification is complemented by an enhanced LSO Presto software development kit (SDK) that has been made available to the MEF developer community on the MEF GitHub.
"The CenturyLink-led MEF 60 provides an essential solution in the overall development of the MEF LSO portfolio of APIs,” said Jack Pugaczewski, Editor of MEF 60 and Distinguished Architect, CenturyLink.
“This development effort is a great example of a traditional standards development and open source hybrid, which resulted in a quality, expedited specification alongside the release of a corresponding API and SDK."
“MEF 60 is an excellent illustration of standards collaboration between industry organisations,” said Pascal Menezes, CTO, MEF. “Specifically, MEF 60 leverages ONF’s TAPI model for network resource activation and topology. The LSO Presto NRP API already is integrated into an OpenDaylight SDN controller plug-in, created by the MEF developer community working alongside the ODL UNI Manager project. And LSO Presto NRP service provisioning scenarios will be tested as part of the OIF 2018 SDN Transport API Interop demo**.”
CenturyLink, Amartus, Ciena, Cisco, Coriant, Ericsson, Huawei, Infinera, Iometrix, NEC, Nokia, and RAD contributed to MEF 60.
An industry association of 200+ member companies, MEF recently introduced the MEF 3.0 transformational global services framework for defining, delivering, and certifying agile, assured, and orchestrated services over a global ecosystem of automated networks. MEF 3.0 services are designed to provide an on-demand, cloud-centric experience with user- and application-directed control over network resources and service capabilities.
MEF 3.0 services are delivered over automated, virtualised, and interconnected networks powered by LSO, SDN, and NFV. MEF produces service specifications, LSO frameworks, open LSO APIs, software-driven reference implementations, and certification programs. MEF 3.0 work will enable automated delivery of standardised Layer 1, Carrier Ethernet, IP, SD-WAN, and Layer 4-7 services across multiple provider networks.
*North-south networking refers to network traffic from a data centre to elsewhere in the network while east-west networking refers to traffic within a data centre.

**In collaboration with MEF, the Optical Internetworking Forum (OIF) announced that the 2018 Joint-Network Operator, Multi-Vendor SDN Transport API (T-API) Interoperability Demonstration will bring new dynamic behaviour use cases and deployment scenarios into network operator labs around the world to test and validate the T-API 2.0 northbound interface (NBI) from the Open Networking Foundation (ONF).
The 2018 event builds on the OIF’s previous 2016 interoperability test and demonstration which addressed multilayer and multi-domain environments as well as on the 2014 demo which prototyped the use of northbound APIs and helped advance transport SDN standardisation. The event will also incorporate service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile specification (MEF 60), which defines T-API extensions in support of MEF Carrier Ethernet services.
