Liaison statement
Liaison Statement to IETF regarding Comments on ANIMA WG charter from ETSI NTECH AFI and suggested synergies and collaboration

We hereby propose ideas on IETF related work that could be carried out par
ANIMA WG to complement the work in ETSI NTECH/AFI WG on Evolution of Management
towards Autonomic Future Internet (AFI) to prevent duplication of work and
effort already undertaken by ETSI NTECH AFI for years. Supplementary details
can be found in the Annexes. This input may be vital to IETF groups that are
working on topics that are closely related to the work of ETSI NTECH/AFI WG.

1. Overall description: Comments on the ANIMA WG Charter

The ETSI NTECH AFI working group is aware that IETF recently created a new
working group on autonomic networking named “ANIMA”. We reviewed the draft
charter description for ANIMA and would like to provide a set of comments and
suggestions on how the two groups could collaborate and complement each other.

2. Actions: Suggested synergies

2.1. IETF related work that could be carried out in IETF/ANIMA WG  to
complement the work in ETSI NTECH/AFI WG

We think at least the following collaboration topics should be of high interest
to both parties:

• The process of analysis of requirements for autonomic behaviors in networks,
in management tasks and in network automation (in general) in order to design
autonomic functions and associated communications on the basis of instantiation
of the GANA model [1] onto target reference architecture, requires answers to
questions such as: • What protocols (could be IETF protocols) can be used by
the instantiated of GANA Functional Blocks (FBs) on the reference points of the
FBs to communicate and to convey data/information • In the target environment,
are there protocols that already exist and could be used as the vehicles • to
communicate the FBs messages and data/information on the reference points, or
should new IETF protocol(s) be designed for that? • What messages, data format
and control semantics should the FBs communicate to implement the requirements
for autonomic behavior and/or automation in general • Are special IETF
protocols required to be introduced?

Those questions imply that IETF protocols and solutions can be introduced to
address them. This may lead to a number of ANIMA WG drafts being introduced.
The requirements analysis is an ongoing process in ETSI NTECH/AFI, and the
outcome can feed input to such ANIMA WG related activities.

• ETSI NTECH/AFI has produced a Technical Specification (recently published)
[2] [3] on Scenarios, Use Cases and Requirements for Autonomic/Self-Managing
Future Internet. ANIMA WG experts can also perform analysis of those scenarios,
use cases and related requirements for autonomic behaviors, in order to derive
ANIMA WG  based solutions to addressing such requirements.

 2.2. Workshops and Tutorials

ETSI NTECH/AFI welcomes the idea of co-organizing workshops or can be invited
to meetings where they can give a tutorial on  AFI work on Autonomic Networking
related Specifications, such as the AFI GANA Reference Model for Autonomic
Networking, Cognitive Networking and Self-Management, and its instantiations
onto various reference architectures toward autonomics-enabled networks, e.g.
during IETF events. For example, ETSI NTECH/AFI does co-organize workshops with
ITU-T SG13, SG2 and SG15, and also with other Multi-SDOs/Fora.

Thank you,
Looking forward to progressing to the next level of our collaboration,

ETSI NTECH AFI Working Group
