The standard for delivery of managed IP services.

IP Services

Why standardize IP services? Automation. Once an IP service needs to go off-net, you enter the complex and time-consuming world of bilateral agreements between service providers. With standard terminology and attributes, the conversation not only becomes easier but one can introduce standard APIs and dramatically accelerate the responsiveness to the subscriber.

The MEF IP Services and API Portfolio

The MEF IP Services and API Portfolio is a comprehensive suite of services designed to empower service providers to seamlessly offer NaaS services and capitalize on the rapidly growing Internet Access services market.

MEF IP Services Portfolio advantages:

  • IP service standards, including the new Carrier Ethernet over Broadband standard.
  • Standardized IP schemas, including new IP services product payload, service schemas, and developer guides.
  • Open standard LSO business APIs and LSO operational APIs.
  • The MEF LSO API Onboarding & Interop Test (OIT) Service and LSO API Certification program.
  • LSO Community.

Defining a Standard IP Service

An IP Service is formed of an IP Virtual Connection (IPVC) that links together IPVC End Points at External Interfaces (EIs). EIs are what MEF calls the boundary between what is the responsibility of the service provider and what isn’t. The interface itself may connect to the end user of the network service, such as an enterprise customer, or it could be another service provider (e.g. access provider). In the case of a Subscriber IP Service, which means it’s a service for an end user, or a retail service, the IPVC End Points are specifically at User Network Interfaces (UNIs). MEF has defined Internet Access Services as its first services’ definition, and is currently working on Private IP VPN Services, to be followed by Operator Services.

MEF 61.1 IP Service Attributes — 2019 May

Amends: MEF 61

Amendments: MEF 61.1.1

Product Portfolio: IP

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.

What Can I Achieve with MEF 3.0 Managed IP Services?

Most managed IP services provided today use non-standard methods and are typically vendor and OS version specific. These bespoke methods become challenging when services need to be delivered across multiple platforms operated by two or more service providers. The result is a proliferation of manual processes or partner-specific, bilateral agreements, automation and API development. Ultimately the subscriber, that is, the enterprise suffers and growth is inhibited. MEF 3.0 IP is your standard for success.

MEF 3.0 Managed IP advantages:

  • Inter-provider service automation.
  • Accelerated interconnection process.
  • IP Service OAM.
  • End-to-end service visibility both on- and off-net.
  • Enhanced user experience.
