To demonstrate the usefulness of WSOL for the management of Web services and their compositions, we have developed a corresponding management infrastructure, the Web Service Offerings Infrastructure (WSOI). WSOI enables monitoring and accounting of WSOL service offerings and their dynamic manipulation. To support monitoring of WSOL service offerings, we have extended the Apache Axis open-source SOAP engine with WSOI-specific modules, data structures, and management ports. To support dynamic manipulation of WSOL service offerings, we have developed appropriate algorithms, protocols, and management port types and built into WSOI modules and data structures for their implementation. Apart from provisioning of WSOL-enabled Web services, we are using WSOI to perform experiments comparing dynamic manipulation of WSOL service offerings and alternatives.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

It provides representation, computation and reasoning mechanisms for semantic description and matching of required and offered capabilities and status which are required by a particular service system. It employs CIM and recently developed languages for the semantic Web in order to provide a mechanism for human-readable and machine-comprehensible descriptions of status, capabilities, system (re)configuration plans as well as exchanging messages. It also exploits XML declarative description (XDD) theory to unify such various languages seamlessly into a single uniform formalism. It permits formal definitions of application-specific configuration requirements and constraints as well as reconfiguration policies. Reasoning about these definitions and the available capabilities/status of nodes in the system yields appropriate (re)configuration plans for the composition of new services and for adaptation of current services.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

Assessing the real-time performance of the application flows is an essential requirement for network operations and service management, as well as for identifying how the different traffic types and transports interact and behave, when they are carried over the end-to-end Internet infrastructure. This paper introduces a novel measurement technique for assessing the performance of IPv6 network flows. By exploiting IPv6 extension headers, measurement triggers and the instantaneous measurement indications are carried in the same packets as the payload data itself. providing a high level of probability that the behaviour of the real user traffic flows is being observed. The measurement mechanism is applied at the network layer and provides for a generic technique able to measure any type of traffic without depending on particular transports or on specific measurement architectures. A prototype implementation of this technique is also described and evaluated by measuring performance properties of application flows over different-capacity IPv6 environments. End-to-end delay and jitter of video streams have been measured, as well as the goodput for services operating on top of reliable transport. This measurement technique can be the basis for low-overhead, scalable, transparent and reliable measurement of individual and aggregate network flows, and can be dynamically deployed where and when required in a multi-service IP environment.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

This tutorial presents a view of the IP network management problem from the perspective of the network itself. It focuses on how to address enhanced manageability requirements in the network infrastructure. This includes what can and should be instrumented inside a network element, and what can and should be instrumented with a scope that goes beyond the individual network element to result in more general \"manageability services\" provided by the network. We discuss the relevance of manageability as a business driver and provide an in-depth analysis of the various factors that contribute to manageability. After this, techniques are presented that can be applied to enhance manageability, also in light of increased focus on applications such as on-demand services, managed services, and plug-n-play networking. We also discuss the role of certain technologies such as XML and Netflow in the emergence of a new generation of management interfaces. Finally, scenarios are used to illustrate how the resulting advances in manageability facilitate not only the development of management applications, but ultimately result in networks that are more autonomous and \"self managing\", and less complex and costly to operate than the norm today.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

On building the minimum number of tunnels: an ordered-split approach to manage IPSec/VPN policies 关于建立最小数量的隧道:一种管理IPSec/VPN策略的有序分割方法

However, it has been shown (Fu et al. (2001)) that the local correctness of IPSec policies in every box individually does not necessarily guarantee global correctness. Therefore, it is critical to have a systematic way to analyze the security requirements globally and to generate, automatically and correctly, a set of IPSec policies to ensure the security for all the end-to-end connections. Previously (Fu et al. (2001)), two different algorithms (i.e. bundle and direct) were introduced to solve the policy generation problem in an \"offline\" fashion. While these two algorithms are efficient in producing globally correct policy rules, the number of output policy rules (i.e., the results themselves) is much greater than necessary. In other words, while the existing approaches can produce a solution quickly, the quality of the solution is far from optimal. In practice, this is undesirable for several reasons. For instance, \"more IPSec policy rules\" implies \"more complicated virtual network topology\". Therefore, in this paper, we focus on \"how to produce a minimum set of IPSec/VPN tunnels\". We formulate this problem as a special type of task-scheduling problem and develop a new method, the ordered-split approach, to produce a provably minimum set of globally correct policy rules. We have also compared the new approach with existing methods in simulation, and our results clearly demonstrate that the ordered-split approach performs significantly better.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

The deployment of operations support systems (OSS), according to the design of an overall target systems architecture, and the reengineering of management processes supporting NIM are the core issues of the proposed solution. Common information and data models are key enabling factors for NIM processes and systems. Information modelling is also the core of standardization efforts for network and service management. Within the operating environments of telecommunication companies (telcos), running either wireline or wireless networks, NIM and the centrality of data have appeared to be key factors for enabling automation of network and service management and deploying effective OSS solutions. The theories and the results discussed have been demonstrated practically and successfully in the operating companies of the Telecom Italia Group. Software solutions for the automation of NIM processes have been deployed since the early 1980s, using early software technologies for database management and building bespoke systems, until some more recent implementations that exploit best-in-class commercial products and successful Web technologies. A practical case study is presented of a successful implementation of an OSS solution for NIM in a mobile company of the Telecom Italia Group.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

Particular attention is given to three areas where most research and development work has focused: natural interfaces (displays, speech, input devices), context awareness, and automated capture and access of live experiences. In addition, we explore a number of systems issues common in the development of pervasive applications, such as networking techniques for creating a pervasive communications infrastructure (especially in the presence of intermittent connectivity), middleware and operating system support, security and privacy. The second part provides an overview of the still nascent field of management of pervasive environments.
