This draft is a work item of the Network Management Research Group Working Group of the IETF. Title : Gap Analysis for Autonomic Networking Authors : Michael H. Behringer Brian Carpenter Sheng Jiang Filename : draft-irtf-nmrg-an-gap-analysis-00.txt Pages : 13 Date : 2014-04-02 Abstract: This document summarises a problem statement for an IP-based autonomic network that is mainly based on distributed network devices. The document reviews the history and current status of autonomic aspects of IP networks. It then reviews the current network management style, which is still heavily depending on human administrators. Finally the document describes the general gaps between the ideal autonomic network concept and the current network abilities.

Shortly, I'll be posting a first draft of a use case. First though, here are a few comments on what Michael proposed for use cases. I have trimmed the text of the proposal: > Problem Statement: Yes, we certainly need this. > Intended user / administrator experience: Yes > Intent: Strictly speaking intent is part of the administrator experience, but should probably explained explicitly with a high-level view Yes, but I'm not so sure it's part of the user experience. At least for my use case, as you'll see, it's probably a vendor default. > Local knowledge: What the function needs to know about the capabilities of the node itself, and which local resources need to be accessed. I found this a bit abstract. Concretely, it's a matter of which parameters each device can decide for itself, without external information. Logically, therefore, it comes before intent (as far as the device is concerned). > Communication requirements: The requirements for message exchange, discovery, negotiation, etc with other autonomic nodes. Firstly, the communication might be with non-autonomic nodes too! Secondly, I found this a bit closer to the solution than the problem. So in my version, this topic is about the information needed from neighbor devices, not about messages. Also, I found that I needed to say something about monitoring (which affects each device, so can't just be described as part of the user experience, although it affects that too). Finally, it seems useful to compare the AN use case with current solutions. If we can't describe benefits, we are a bit stuck. > Use cases are not required to outline a solution in detail Understood. But it's a matter of taste and judgment where the problem statement stops and hints of the solution begin... Anyway - the best test for all this is an example use case, which will come very soon.

However, they are largely independent, and each has its own methods and protocols to communicate, discover, define and distribute policy, etc. > The goal of the work on autonomic networking in the IETF is therefore not just to create autonomic functions, but to define a common infrastructure that autonomic functions can use. This autonomic networking infrastructure may contain common control and management functions such as messaging, service discovery, negotiation, intent distribution, etc. A common approach to define and manage intent is also required. > Refer to the reference model below: All the components around the "autonomic service agents" should be common components, such that the autonomic service agents do not have to replicate common tasks individually. >

This section explains how case studies should be outlined and what they should describe: > > Title > Problem Statement: An explanation which problem is being addressed, with information about existing solutions and their shortcomings. > Intended user / administrator experience: The goal of autonomic networking is to simplify network administration and usage. Use cases should point out how their experience differs from current solutions. If a use case depends on configuration, it may include configuration samples, although obviously the goal is to reduce or eliminate configuration. > Intent: Strictly speaking intent is part of the administrator experience, but should probably explained explicitly with a high-level view on how the autonomic function could be defined in intent (if required). > Local knowledge: What the function needs to know about the capabilities of the node itself, and which local resources need to be accessed. > Communication requirements: The requirements for message exchange, discovery, negotiation, etc with other autonomic nodes. > > > Use cases are not required to outline a solution in detail, nor to specify precise protocol or intent details. They are used at this point to determine a consolidated approach to developping an autonomic networking infrastructure. >
