Network Management Research Group Report
November 2005:

[1] The 19th NMRG meeting is under preparation. We are planning a two
   day meeting focusing on (a) promise theory and (b) P2P approaches
   for network management. The meeting is tentatively scheduled for
   January 2006 and will be hosted by the KTH in Stockholm (Sweden)
   or the University College Oslo (Norway).

   Promise theory has been proposed by a group working at the UC Oslo
   (Norway) as a new way to describe how policy-based systems or
   self-organizing systems are organized. Traditional policy-based
   systems are based on policy rules sets where each rule is made up
   of conditions (expressions) and actions.  Sometimes, rules can be
   explicitly bound to event (on <event> if <condition> then <action>
   rules). This rule-based approach ultimately requires logics for
   the analysis of such rule-based policy systems (e.g., for conflict
   detection).  Promise theory, on the other hand, takes a graph
   theoretic approach which puts promise relationships between nodes
   into the main focus. Promise theory therefore leads to
   graph-theoretic approaches for analysis and reasoning.

   P2P approaches to network management are being researched by a
   group at the KTH Stockholm (Sweden). Their goal is to establish
   management overlays that organize the distribution of management
   information and distributed automatic aggregation of data in the
   management overlay network. The purpose is to find out in which
   areas P2P approaches can be used for management and whether such
   technologies allow to overcome the classic hierarchical network
   management model.

[2] Work is (slowly) making progress on network management traffic
   measurements on production networks. The goal is to obtain hard
   data how management protocols are used in practice in order to
   better understand the protocols strengths and shortcomings and
   the requirements for alternate new management mechanisms. The
   measurement and data analysis tool-set is currently being worked
   on and first results are expected to be available in the Summer
   2006.
