With the emergence of new applications and requirements it became necessary to create new monitoring and reactive configuration mechanisms to try to meet the SLAs (Service Level Agreements). In WDM (Wavelength Division Multiplexing) optical networks, one way of trying to fulfill these agreements is by using pre-established protection paths. However, despite guaranteeing that traffic will be rapidly routed to its protection path in case of failure, there is no guarantee that the latter will be capable of meeting the contracted SLA in accordance with the bit error rate of its links. In this article we propose a scheme for monitoring and selecting the SRLG (Shared Risk Link Group) protection path disjointed from the main path using Genetic Algorithms, Fuzzy Logic in a PBM (Policy Based Management) platform denominated GAFUDI.
随着新应用程序和需求的出现，有必要创建新的监视和响应式配置机制，以尝试满足sla(服务水平协议)。在WDM(波分复用)光网络中，尝试实现这些协议的一种方法是使用预先建立的保护路径。然而，尽管保证在发生故障时将流量快速路由到其保护路径，但不能保证后者能够按照其链路的误码率满足合同SLA。在本文中，我们提出了一种在PBM (Policy Based Management)平台GAFUDI中使用遗传算法和模糊逻辑来监测和选择与主路径脱节的SRLG (Shared Risk Link Group)保护路径的方案。

The efficiency and the performance of management systems is becoming a hot research topic within the networks and services management community. This concern is due to the new challenges of large scale managed systems, where the management plane is integrated within the functional plane and where management activities have to carry accurate and up-to-date information.

Firewalls remain the main perimeter security protection for corporate networks. However, network size and complexity make firewall configuration and maintenance notoriously difficult. Tools are needed to analyse firewall configurations for errors, to verify that they correctly implement security requirements and to generate configurations from higher-level requirements. In this paper we extend our previous work on the use of formal argumentation and preference reasoning for firewall policy analysis and develop means to automatically generate firewall policies from higher-level requirements. This permits both analysis and generation to be done within the same framework, thus accommodating a wide variety of scenarios for authoring and maintaining firewall configurations. We validate our approach by applying it to both examples from the literature and real firewall configurations of moderate size (≈ 150 rules).

Providing inter-domain QoS guaranteed services is a huge challenge for operators and will bring new revenues to them. But, establishing end-to-end services requires a level of resource management that does not exist yet, even locally to an operator. Due to confidentiality and independence reasons, operators are afraid to cooperate which can not be avoided in the inter-domain context. We consider the existence of an alliance framework wherein operators would agree to cooperate. In this article, we address the issues of negotiating inter-domain services and propose efficient algorithms to determine the end-to-end QoS contract that will satisfy the QoS demand for a service.

SIP-based networks are becoming the de-facto standard for voice, video and instant messaging services. Being exposed to many threats while playing an major role in the operation of essential services, the need for dedicated security management approaches is rapidly increasing. In this paper we present an original security management approach based on a specific vulnerability aware SIP stateful firewall. Through known attack descriptions, we illustrate the power of the configuration language of the firewall which uses the capability to specify stateful objects that track data from multiple SIP elements within their lifetime. We demonstrate through measurements on a real implementation of the firewall its efficiency and performance.

As wireless mesh networks become more popular, there exists a need to provide centralized management solutions, which facilitate network administrators to control, troubleshoot and collect statistics from their networks. Managing wireless mesh networks poses unique challenges due to limited bandwidth resources and dynamic channel quality. A robust management solution should function despite network layer failure. In this paper, we propose MeshMan, a network layer agnostic, low overhead solution to network management to cope with unreliable wireless channels, link and network level dynamics in wireless mesh networks. It combines the concepts of source routing with hierarchical addressing, and provides a native efficient query interface. A prototype of MeshMan has been implemented as a user space daemon on Linux and evaluated using a 12-node wireless mesh network testbed. Experimental studies demonstrate that MeshMan has comparable or better performance than the Simple Network Management Protocol (SNMP) in management overhead and response times when the network is stable while having much better performance in presence network dynamics.

Enabling the automated deployment and maintenance of current and future services over the Internet is a difficult task and requires self-aware functions that can adapt the services offered by the network to changing customer demand, business goals, and/or environmental conditions using policies. This paper describes a process to realise static and dynamic service deployment, given an understanding of available resources that exist in a communications network to build services . This process contributes to the realisation of the AutoI autonomic management architecture for the Internet, which aims to develop a self-managing virtual resource overlay that can span across heterogeneous networks and supports service mobility, security, quality of service and reliability. The core of the process is to take advantage of the substantial DEN-ng information model that decouples the definition and design of services from the resources available in the network. In this way, the creation and modification of services within a network can be planned, deployed, and even dynamically composed to meet context-aware demands. Providing such a service-aware process is central to the architecture being defined in the AutoI project and information modelling is seen as a major facilitator to this task.

Traditional networks are surprisingly fragile and difficult to manage. The problem can partly be attributed to the exposition of too many details of the controlled objects leading to the deluge of complexity in control plane, and the absence of network-wide views leading to the blindness of network management. With these problems, this paper decomposes the necessary network management information into three parts: the basic information, the cross-layer association, and global information. And a new controlled object description model is presented in the trustworthy and controllable network control architecture which separates the functionality of control and management of network form the data plane of IP network, and constructs the formal control and management plane of IP network. The new model identifies and abstracts the controlled objects with object-oriented approach. Based on this model, a cross-layer database is built to store the different layer control objects and to present cross-layer association view, a processing mechanism to process the original information is presented for global network state view, and a control plane is constructed to realize network control. The control information description model restricts the complexity of the controlled objects to their own implementation by abstraction, and alleviates the difficulty of network management. The cross-layer association view and the global network state view composes the network-wide views. The network-wide views realize the visibility and improve the manageability of network. Finally, we present 3 examples to indicate that the model alleviates the complexity of configuration management.

Massively Online Virtual Environments (MOVEs) have been gaining popularity for several years. Today, these complex networked applications are serving thousands of clients simultaneously. However, these MOVEs are typically hosted on specialized server clusters and rely on internal knowledge of the services to optimize the load balancing. This makes running MOVEs an expensive undertaking as it cannot be outsourced to third party hosting providers. This paper details two Integer Linear Programming approaches to optimize the MOVE deployment through load balancing and minimizing the delay experienced by the end-users. Optimization includes assigning MOVE components to resources and replication of components to increase the scalability. One approach assuming full application knowledge of a dedicated MOVE and one with no internal knowledge and geared toward a generic MOVE hosting platform. For both cases an optimizing heuristic is evaluated and the obtained results are compared.

Monitoring the end-to-end Quality-of-Service (QoS) is an important work for service providers' Operation Support System (OSS), because it is the fundamental requirement for QoS provisioning. However, it is in fact a challenging work, and there are few efficient approaches to address it. In this paper, for Multi-Protocol Label Switching (MPLS) Virtual Private Networks (VPNs), we propose a queuing model based end-to-end performance evaluation scheme for OSS to monitor the end-to-end delay, which is one of the important QoS metrics. By means of a queuing model, we deduce the relationship between the end-to-end delay and the information available in the Management Information Base (MIB) of routers, and then we present the evaluation scheme which avoids the costly per-packet measurement. The complexity of the proposed scheme is much lower than existing schemes. Extensive simulation results show that the proposed scheme can efficiently evaluate the end-to-end performance metrics (the estimation error is nearly 10%).
