Purpose: For information

Body: Following the previous liaisons between our organizations, we would like to provide an update on the status of the active projects in MEF that relate to IP Services. There are four active projects:

IP Service Attributes. This project is defining the generic Service Attributes that are agreed between the provider and user of an IP Service, to describe the service being provided. MEF 61, covering Service Attributes for Subscriber IP Services (for end users), was published in April 2018. We have since been working on a revision to this standard, to add support for wholesale IP Services between Operators. An Approved Draft of the revision was included in an earlier liaison, and a Letter Ballot (final approval) has now been initiated. Publication of the revision is expected in Q2 2019.

IP Service Definitions. This project is defining a number of specific IP Services, based on the Service Attributes defined in MEF 61. The initial phase is focusing on two forms of Internet Access Service: Consumer-grade Internet Access, and Commercial-grade Internet Access. A later phase will also define one or more IP-VPN Services. A Letter Ballot (final approval) on the first phase is expected to be initiated in April 2019, with publication to follow in the Summer.

Service OAM for IP Services. This project is defining how Fault Management and Performance Monitoring can be performed for IP Services (based on techniques and protocols defined in IETF). Fault Management is based on ping, traceroute, and BFD. Performance Monitoring is based on TWAMP, TWAMP-light and STAMP. The initial phase is focusing on Subscriber IP Services, and a Draft Standard release of this document is available on the MEF public web site (see below). We would welcome any comments you have on this Draft Standard. A Letter Ballot (final approval) is expected to be initiated in April 2019, therefore we would request that you send any comments by the end of March 2019.

Service Activation Testing for IP Services. This project is defining a methodology for Service Activation Testing of IP Services. The initial phase again focuses on Subscriber IP Services, based on the Service Attributes in MEF 61. A later phase will cover IP Services between Operators. A Draft Standard for review is expected to be available in Spring 2019.

Note that MEF has replaced our previous mechanism of "Approved Drafts", which were shared only with liaison partners and could be accessed using a username and password, with a mechanism of Draft Standards, which are published on the MEF web site. Current Draft Standards can be found at Published MEF Standards can be found, as always, at

The forthcoming MEF meetings are:
29 April - 2 May, 2019 - Dubrovnik, Croatia
29 July - 1 August, 2019 - North America
