In this paper, as a forecasting method, the market survey for forecasting demand is introduced for the estimation of subscriber line demand in the optical access networks. The market survey method for the new multimedia services is attempted to collect information directly from customers using the questionnaires for home-users and business-users in local loops. Analysis rationale of questionnaires is suggested to estimate the number of subscriber lines. Also, two measures are presented to quantify the credibility on survey responses; one is the probability that the customer will use the multimedia services and the other is the rate that the subscriber line demand will be actually realized. The former measure is calculated based on the information on customers and the Logit analysis. The latter is obtained by the degree of customer's knowledge about specific services and the customer's willingness to use the services. Based on the values of two measures, the number of subscriber line demand can be developed for installing the optical access networks.

This study examined the current practices of Research Data Management (RDM) services recently built and implemented at research university libraries in the U.S. by analyzing the components of the services and the contents presented in their web sites. The study then analyzed the content of web pages describing the services provided by 31 Research Universities/Very High research activity determined based on the Carnegie Classification. The analysis was based on 9 components of the services suggested by previous studies, including (1) DMP support; (2) File organization; (3) Data description; (4) Data storage; (5) Data sharing and access; (6) Data preservation; (7) Data citation; (8) Data management training; (9) Intellectual property of data. As a result, the vast majority of the universities offered the service of DMP support. More than half of the universities provided the services for describing and preserving data, as well as data management training. Specifically, RDM services focused on offering the guidance to disciplinary metadata and repositories of relevance, or training via individual consulting services. More research and discussion is necessary to better understand an intra- or inter-institutional collaboration for implementing the services and knowledge and competency of librarians in charge of the services.

Seamless end-to-end Internet Quality of Service (QoS) management is very only because Internet Management is not well understood and practiced in the real world but because the nature of the Internet is hard to predict and manage. Secure transmission, transport reliability, ability to differentiate service qualities, QoS-based intelligent routing, QoS monitoring, and customer-oriented service management are essential technical huddles to be coped with. Despite of these difficulties, the Internet becomes the platform of choice for the next generation applications and services. without a solid management solution, it is not easy to deploy high quality commercial services. In this paper, we propose an architecture of seamless end-to-end Internet QoS Management System and describe the design principles and system components of our developing prototype system.

In recent years, a life phenomenon using a workflow management tool in bioinformatics has been actively researched. Workflow management tool is the base which enables researchers to collaborate through the re-use and sharing of service, and a variety of workflow management tools including MyGrid project's Taverna, Kepler and BioWMS have been developed and used as the open source. This workflow management tool can model and automate different services in spatially-distant area in one working space based on the web service technology. Many tools and databases used in the bioinformatics are provided in the web services form and are used in the workflow management tool. In such the situation, the web services development and stable service offering for a sequence similarity search which is basically used in the bioinformatics can be essential in the bioinformatics field. In this paper, the similarity retrieval speed of biology sequence data was improved based on a Linux cluster, and the sequence similarity retrieval could be done for a short time by linking with the workflow management tool through developing it in the web services.

Differentiated services (DiffServ) architecture defines a new framework for the support of quality of service (QoS) in IP-based networks. RIO has received the most attention among all the active queue management mechanisms proposed for assured service in DiffServ environment. The paper proposed the enhanced RIO which could alleviate the impact of flow's packet sire on the realized throughput. The simulation results indicate that this mechanism, when combined with TSW as traffic conditioner, provide better throughput assurance and fair distribution of excess bandwidth independent of packet size of flows in case of well-provisioned network environment.

The network management becomes more complicated due to the growth of network technology and introduction of a large number of new multimedia services. TINA has appeared as a concept for the advanced network management system platform using the information technology such as distributed processing and object oriented modeling. Since TINA is on the basis of DPE (Distributed Processing Environment), it can manage networks and services for open telecommunications. In this paper, we propose an implementation strategy of the MIB/MIT to federate various CORBA objects in CORBA based network management system implementing TINA DPE. The proposed strategy is novel in the sense that it can support the distribution of MIB/MIT that is well matched with the distributed component architecture of TINA DPE, and it can also support the scoping and filtering services on the MIT using CORBA Naming Service.
