The network service provider (NSP) must manage network resources and multiple protocol label switching can be used to control logical path allocation. This paper proposes a scheme that maximizes NSP profit by controlling the service-list and path-allocation under the constraint of available network resources. We introduce a model in which the users' class choice from among the multiple classes is influenced not by the price and QoS of one class, but the prices and QoS levels of all classes, the service-list. To model the users' class choice, we adopt discrete choice analysis. We propose a functional framework that consists of user choice model function, original demand forecast function, and service-list and path-allocation determination function. We evaluate the effectiveness of the proposed method using a multiple service-class example.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

We apply our method to a real network topology with various types of network faults. Experimental results show that our approach can detect and localize the faults in a timely manner, yet without disrupting normal network operations.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

The host service time distribution is exploited to locate caches in the SAN, detect and isolate contention in the communication channels and backend disk drives. We define essential metrics and measure I/O workloads over extended periods to define baseline behavior. We have implemented architecture to acquire configuration and performance data from agents on the host and SAN elements. In addition to performance management this data is the basis of management functions such as capacity planning, and sizing host and SAN resources required for application rollout and expansion. The static dependency map (SAN topology or 'wiring' diagram), provided by current SAN management tools, is extended into the host server. We then attempt to develop a corresponding dynamic dependency view showing how performance metrics at the application and host level, such as I/O queuing levels and service times, relate to response times in the SAN. The dynamic view is also an important complement to the static dependency graph because the actual traffic flow may be difficult to deduce from the topology.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

This paper presents a series of comparative performance tests on two common platforms used for network management: SNMP and CORBA. In terms of network performance, the two platforms are used to achieve the same network management tasks. The bandwidth consumed and the time taken to complete the tasks is compared. Both systems were tested by manipulating different types of management objects (single or tabular) in different network environments. The results highlight the bottlenecks in each system and the reasons for them. The paper compares both systems and identifies their respective advantages and disadvantages. The work shows that their different features will decide what kind of application they are most suited to.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

These require modifications to current business processes in the OSS. Alternatively, they could require new systems. We have faced difficulties in adopting new data or Internet services in time to market because of complex system structures, inter-operations, etc. To address market needs, we have been promoting the NeOSS (new operations support systems) project since 2001. We have just completed its design level, and are currently implementing it. In these processes, we are still facing many problems and difficulties. We focus on \"service assurance\", and describe what the problems in the KT OSS are, and how we are approaching them from the point of view of the architectures and technologies and of inter-operations with legacy systems.

Patterns for routing and self-stabilization 路由和自稳定模式

We propose the use of navigation patterns, which define how information for state updates is disseminated in the system, as fundamental building blocks for self-stabilizing systems. We present two navigation patterns for self-stabilization: the progressive wave pattern and the stationary wave pattern. The progressive wave pattern defines the update dissemination in Internet routing systems running the DUAL and OSPF (open shortest path first) protocols. Similarly, the stationary wave pattern defines the interactions of peer nodes in structured peer-to-peer systems, including Chord, Pastry, Tapestry, and CAN. It turns out that the two patterns are related. They both disseminate information in the form of waves, i.e, sets of messages that originate from single events. Patterns can be instrumented to obtain wave statistics, which enables monitoring the process of self-stabilization in a system. We focus on Internet routing and peer-to-peer systems, since we believe that studying these (existing) systems can lead to engineering principles for self-stabilizing systems in various application areas.","PeriodicalId":260367,"journal":{"name":"2004 IEEE/IFIP Network Operations and Management Symposium (IEEE Cat.

To provide a method of meeting this requirement, we applied semantic Web and ontology technology to achieve information integration between enterprises.
