On the Impact of Management Instrumentation Models on Web Server Performance: A JMX Case Study
Abdelkader Lahmadi; Anca Ghitescu; Laurent Andrey; Olivier Festor
JMX (Java Management eXtension) is a Java framework that allows any Java technology-based application or accessible resource to become easily manageable. This standard begins to be widely used within different managed systems which vary from large mainframes to small mobile devices, limited in both resource and computing capacity. Today, little is known about the costs associated with the manageability of a system. In this paper, we analyse the impact of various instrumentation models on the behavior of both the functional and the management plane. We show on a JMX instrumented web server that the service is highly affected by the management activity in driver and component models while a daemon approach limits the management impact on the functional service.

RAQNet: A Topology-Aware Overlay Network
Seyed Iman Mirrezaei; Javad Shahparian; Mohammad Ghodsi
Peer-to-peer overlay networks provide a useful infrastructure for building distributed applications. These networks provide efficient and fault-tolerant routing and object locating within a self-organizing overlay network. This paper presents a multi-dimensional overlay network called RAQNet which is based on RAQ. RAQ supports exact match queries and range queries over multi-dimensional data efficiently. Moreover, its routing cost does not depend on the dimension of the search space. In RAQNet, we have improved its original routing algorithms and extended it to have topology awareness property. In RAQNet, nodes are connected to each other if their labels are “close” to each other with respect to the topology of its underlying network. A topology match between the overlay and underlying network results in reduced routing delay and network link traffic. In comparison with RAQ, we will describe different node-join algorithms and routing table maintenance in order to provide the topology awareness. We present the experimental results through a prototype implementation of two emulated networks.

IBGP Confederation Provisioning
M. Nassar; R. State; O. Festor
This paper proposes an optimization method for the design of large scale confederation based BGP networks. We propose a graph based model and an associated metric to evaluate the reliability of large scale autonomous systems. We propose and validate an effective methodology to find the optimal design for a given physical topology. According to our experiments, we consider that replacing the traditional IBGP topology by an appropriate confederation design could increase at the same time the scalability and the reliability into the domain. Our work might be a step further towards a large scale confederation deployment.

Ontology-Based Management for Context Integration in Pervasive Services Operations
J. Martín Serrano; Joan Serrat; Sven van der Meer; Mícheál Ó Foghlú
Next generation networks require information and communications systems able to support pervasive services and especially context-aware applications. This paper presents research challenges in self-management, autonomic communications and integration requirements of context information for supporting management operations of such services in next generation networks. The research focuses on a framework of information systems and their interoperability. Management techniques using information and data models for context information are discussed and studied and then the novel system architecture for context handling and delivery using ontology-based models is presented. In this paper, ontology-based management and modelling techniques are used and referenced in the framework of a distributed context handling and delivery system. Following this, the representative ontology-based information management system within an application scenario is presented. The flexibility of the introduced approach allows for end-user scenarios, which are briefly described at the end of the paper.

A Terminology for Control Models at Optical Exchanges
Freek Dijkstra; Bas van Oudenaarde; Bert Andree; Leon Gommans; Paola Grosso; Jeroen van der Ham; Karst Koymans; Cees de Laat
Optical or lambda exchanges have emerged to interconnect networks, providing dynamic switching capabilities on OSI layer 1 and layer 2. So far, the only inter-domain dynamics have occurred on layer 3, the IP layer. This new functionality in the data plane has consequences on the control plane. We explain this by comparing optical exchanges with current Internet exchanges.
Descriptions of optical exchanges have appeared in the literature, but discussions about these exchanges have been hampered by a lack of common terminology. This paper defines a common terminology for exchanges. Discussion in the community revealed four different meaning for the term “open exchange”. We list them in this paper.
We classify the different kind of exchanges based on the interactions between the domains at the control plane. We use these control models to distinguish between different types of interconnection points.

Self-forming Network Management Topologies in the Madeira Management System
Liam Fallon; Daryl Parker; Martin Zach; Markus Leitner; Sandra Collins
This paper describes a novel approach to network management topologies where multiple customized topologies are self-configured, self-optimized, and maintained automatically by the underlying network of elements. An implementation of these self-forming management topologies as developed in the Celtic European research project Madeira is described. The self-forming topologies use peer-to-peer communication facilities provided by the Madeira platform running on each network element and give a view of the complete network topology, with customization optimised for individual management functionality. Finally, experiences in utilising these topologies are described, highlighting the benefits of this novel approach.

Activity-Based Scheduling of IT Changes
David Trastour; Maher Rahmouni; Claudio Bartolini
Change management is a disciplined process for introducing required changes onto the IT environment, with the underlying objective of minimizing disruptions to the business services as a result of performing IT changes. Currently, one of the most pressing problems in change management is the scheduling and planning of changes. Building on an earlier mathematical formulation of the change scheduling problem, in this paper we take the formulation of the problem one step further by breaking down the changes into the activities that compose them. We illustrate the theoretical viability of the approach, discuss the limit of its applicability to real life scenarios, describe heuristic techniques that promise to bridge the scalability gap and provide experimental validation for them.

Estimating Reliability of Conditional Promises
Alva L. Couch; Hengky Susanto; Marc Chiarini
Using conditional promises, the reliability of promises can be measured without reference to the reliability of the issuing agent, by defining notions of when conditions operate and when promises are expected to be fulfilled. This inspires an analytical method that attributes promise failures to incomplete knowledge rather than agent unreliability. This analysis allows agents to choose between conditional offers of service based upon statistical measures of the completeness of stated conditions.

Modeling Change Without Breaking Promises
Alva L. Couch; Hengky Susanto; Marc Chiarini
Promise theory defines a method by which static service bindings are made in a network, but little work has been done on handling the dynamic case in which bindings must change over time due to both contingencies and changes in policy. We define two new kinds of promises that provide temporal scope for a conditional promise. We show that simple temporally-scoped promises can describe common network behaviors such as leasing and failover, and allow an agent to completely control the sequence of sets of promises to which it commits with another agent, over time. This allows agents to adapt to changing conditions by making short-term bilateral agreements rather than the long-term unilateral agreements provided by previous promise constructions.

Norms and Swarms
Mark Burgess; Siri Fagernes
This paper describes a position for work in progress. We offer a definition of a “swarm” using the management concepts of promises and information rather than the programmed rules commonly used to mimick swarm behaviour. We look for a general and underlying meaning to swarms as a form of organization. Noting that swarms lead to an autonomous reduction of total information of the ensemble of agents, we propose that our definition of swarming suggests criteria for achieving fully decentralized, ad hoc network management without dedicated specialist controllers.
