Active Technologies for Network and Service Management: Report on DSOM'99
DSOM’99, the Tenth IFIP/ IEEE International Workshop on Distributed Systems: Operations and Management followed a series of annual meetings, the latest of which took place in Delaware, (DSOM’98) [1], Sydney, Australia (DSOM’97) [2], and L’Aquila, Italy (DSOM’96) [3]. DSOM is a single-track workshop of the management research community. The workshop traditionally stresses interaction and encourages active participation. DSOM’99 was hosted by the Computer Engineering and Networks Laboratory (TIK) of the Swiss Federal Institute of Technology ETH Zürich from October 11–13 in Zürich, Switzerland. Ninety participants attended the event. DSOM’99 was supported by Ascom, BT, IBM, GTE, Lucent, and Swisscom. For technical paper sessions, 55 submissions had been received, out of which 20 were selected for presentation and are published in the workshop proceedings [4]. Ten papers in the program came from Europe, eight papers from the Americas, and two papers from Asia. About half of the contributions originated from industry labs, the other half from academia. The program was structured into seven paper sessions, with a panel at the end of each day. A keynote speech opened up the program.
Emerging Management Technologies and Directions Debated at DSOM 96
The 7th IFIP/ IEEE Distributed Systems Operation and Management (DSOM 96) Workshop was held during October 28± 30th. 1996 in l’Aquila, right in the center of Italy under the towering peaks of the Italian Appennine range. Getting there was not probably easy for a number of the 80 participants who came from 17 countries, but it was worth the trip. On the other hand a conference that deals with managing distributed systems has to be distributed all over the world. Distributed systems, as was remarked in the introductory address by the DSOM chair Roberto Saracco, are a reality: the thousands of computers making up a telecommunication network or the hundreds at the core of an enterprise network are there as witness. They are no longer clusters of stand-alone machines, but they are interconnected to one another through a variety of systems and networks. There were three major themes during the three-day workshop. The ® rst theme was the advanced research on different aspects of distributed technology. This included intelligent and mobile agent technology, policy-based agents, delegated agents, and programmable networks. Mobility, delegation, and programmability have been identi® ed as key attributes for future networks. Also, it was recognized during the sessions that there is a need in the research community to put more emphasis on service management and information sharing rather than physical layer management and protocols. The second theme, which generated a lot of hot discussions during the workshop, dealt with the Internet applications and Web-based management technologies. Future networks will witness more customer participation and migra-
DESIGN CONCEPT OF THE SOIL IMPROVEMENT FOR ROAD CONSTRUCION ON SOFT CLAY
This paper presents an innovative use of soil-cement mixing method using jet grouting technique to improve the bearing capacity of subbase foundation for road construction in Thailand. The construction sequences and the basic design example of jet grouting for embankment works on soft clay are also given in this paper. The design concept and method of analysis of jet grouting work using finite element technique, results of finite element analysis, the installation adopted and effectiveness of soil improvement system are given and discussed. It was found that the total settlement is reduced by the jet grouting. A case history at Pak Phanang Diversion Dam project, Nakornsrithamarat, Thailand is presented describing the engineering design and construction aspects of a successful project, which demonstrated the advantage of soil-cement mixing method over conventional pile driving for this site.
