Web‐based Communication and Information System tools Information and knowledge management are increasingly recognized as important features in effective and efficient work in the water sector (Dondeynaz et al. 2009). (...) Figure 55 – The Brisbane City Web based Flood Map Source: http://www.sweetmaps.com/blog/wp‐content/uploads/2011/01/BCC_esri_flood_map.jpg Web‐based servers offer access to integrated information from heterogeneous data sources, as well as the innovative tools for analysis and assessment of a broad area such as climate change, water scarcity, human health, sanitation and urbanization necessary for proper urban water management. Integration of such web based communication tools using open communication standards allow a range of stakeholders to connect to the system, to use or add to its resources.

Web‐based communication and information system tools Information and knowledge management are increasingly recognized as an 32 important features for the effectiveness of the water sector . A key problem faced within the sector is the existence of a large body of complex, unstructured and fragmented data. Web‐based interfaces and online platforms provide a solution to enable the effective management, display, and retrieval of relevant information required by water managers/operators, urban planners, governments and the public. Figure 11 provides an example of the role played by web‐based technologies in city‐based flood maps.

Preconditions Three service function entities are deployed by the operator, which are uniform resource locator (URL) filter, protocol optimization and video optimization. Policies are defined such that the flow of a hypertext transport protocol (HTTP) video service should go to the URL filter and video optimization, and the flow of the web browsing service should go to the URL filter and protocol optimization. Operational flows Figure I.1 – Flexible traffic steering scenario 1) There are two groups of flows initiated by users: HTTP video; web browsing. 2) The flows of each group are identified and separated by mobile core network. 3) The HTTP video flow goes through URL filter and video optimization. The web browsing flow goes through URL filter and protocol optimization.

Tutorial on Fast Web Services
Tutorial on Fast Web Services
This document provides tutorial material on Fast Web Services (it is equivalent to Annex C of X.892 | ISO/IEC 24824-2). Some of the advantages of using Fast Web Services are described. The differences between the conceptual and optimized processing of SOAP messages are highlighted, followed by an example. (...) This provides the main advantage (fast computer processing and low message bandwidth) of Fast Web Services, but a number of further optimizations of XML SOAP are discussed below.
