The TISDAG (Technical Infrastructure for Swedish Directory Access Gateway) project provided valuable insight into the current reality of deploying a wide-scale directory service. This document catalogues some of the experiences gained in developing the necessary infrastructure for a national (i.e., multi-organizational) directory service and pilot deployment of the service in an environment wit...

The last decades have seen the emergence of the sea of objects paradigm for structuring complex distributed systems on workstations and local area networks. In this approach, applications and system services are composed of and communicate among themselves through reliable and transparently accessible object interfaces, leading to the interaction of hundred or thousands of unstructured objects....

Sharing global remote data over large networks poses two major problems: rstly, the data must be discovered; and secondly, the data must be made accessible to the application. Our aim is to provide a single uniied interface to both local and remote data, removing location dependence and improving performance. Our solution incorporates shared memory and caching techniques. A location server prov...

Recent development of distributed cloud environments requires advanced network infrastructure in order to facilitate network automation, virtualization, high performance data transfer, and secured access of end-to-end resources across regional boundaries. In order to meet these innovative cloud networking requirements, software-defined wide area network (SD-WAN) is primarily demanded to converg...

A wide area quantum key distribution (QKD) network deployed on communication infrastructures provided by China Mobile Ltd. is demonstrated. Three cities and two metropolitan area QKD networks were linked up to form the Hefei-Chaohu-Wuhu wide area QKD network with over 150 kilometers coverage area, in which Hefei metropolitan area QKD network was a typical full-mesh core network to offer all-to-...

Grid Computing is a wide-area computing infrastructure viewed by many as a promising next generation platform for solving large-scale problems. Most of the current research projects concentrate on constructing middleware to provide pervasive, dependable, and consistent access to geographically distributed computational resources connected by a wide-area network. As an alternative, we are studyi...

| The Terminode project follows a system approach to investigate wide area, large, totally wireless networks that we call mobile ad-hoc wide area networks. A network of terminodes is an autonomous, self-organized, wireless multimedia network, independent of any infrastructure. In this paper we present the main challenges and certain initial technical directions.

Recent developments in networking technology cause a growing interest in connecting local-area clusters of workstations over wide-area links, creating multilevel clusters. Often, latency and bandwidth differences between local-area and wide-area network links are two orders of magnitude or more. With such a large difference, one would expect only very coarse grain applications to achieve good p...
