Signaling System No. 7 SS7/C7): Protocol, Architecture, and Services Networking Technology

Signaling process No. 7 (SS7) is a signaling community and protocol that's used globally to deliver telecommunications networks, either fixed-line and mobile, to existence. SS7 has a number of functions and is on the very center of telecommunications. developing cell calls, supplying mobile roaming and messaging, and providing converged voice and information companies are just a number of the ways in which SS7 is utilized in the communications community.

Service Quality of Cloud-Based Applications

This e-book explains why purposes operating on cloud would possibly not bring an analogous carrier reliability, availability, latency and total caliber to finish clients as they do whilst the purposes are operating on conventional (non-virtualized, non-cloud) configurations, and explains what may be performed to mitigate that danger.

Protocols for secure electronic commerce

Protocols for safe digital trade, 3rd version offers a compendium of protocols for securing digital trade, or e-commerce, in patron- and business-to-business functions. getting to numerous digital check structures at the moment in use world wide, this variation: Updates all chapters to mirror the most recent technical advances and advancements in components equivalent to cellular trade provides a brand new bankruptcy on Bitcoin and different cryptocurrencies that didn't exist on the time of the former variations book raises the assurance of PayPal in line with PayPal’s amplified function for shoppers and companies Expands the dialogue of credit cards, dedicating an entire bankruptcy to magnetic stripe playing cards and an entire bankruptcy to chip-and-PIN know-how Protocols for safe digital trade, 3rd variation deals a state of the art evaluation of top practices for the safety of e-commerce, whole with end-of-chapter overview questions and an intensive bibliography of specialised references.

Network reliability: measures and evaluation

In Engineering idea and purposes, we predict and function when it comes to logics and versions with a few appropriate and moderate assumptions. the current textual content is geared toward offering modelling and research concepts for the assessment of reliability measures (2-terminal, all-terminal, k-terminal reliability) for platforms whose constitution may be defined within the kind of a probabilistic graph.

8 Summary and Future Development.......................................................... 36 References................................................................................................................ 37 17 18 Cloud Computing with e-Science Applications Summary This chapter discusses the challenges that are imposed by big data on the modern and future e-scientific data infrastructure (SDI). The chapter discusses the nature and definition of big data, including such characteristics as volume, velocity, variety, value, and veracity.

Published data that support one or another scientific hypothesis, research result, or statement. These data are typically linked to scientific publications as supplemental materials; they may be located on the publisher’s platform or authors’ institution platform and have open or licensed access. • Data linked and embedded into publications to support wide research consolidation, integration, and openness. Once the data are published, it is essential to allow other scientists to be able to validate and reproduce the data in which they are interested and possibly contribute new results.

3 Research Infrastructures and Infrastructure Requirements This section refers to and provides a short overview of different scientific communities, in particular as defined by the European Research Area (ERA) [21], to define requirements for the infrastructure facility, data-processing and management functionalities, user management, access control, and security. 1 Paradigm Change in Modern e-Science Modern e-science is moving to the data-intensive technologies that are becoming a new technology driver and require rethinking a number of infrastructure architecture and operational models, components, solutions, and processes to address the following general challenges [2, 4]: Cloud-Based Infrastructure for Data-Intensive e-Science Applications 25 • Exponential growth of data volume produced by different research instruments or collected from sensors • Need to consolidate e-infrastructures as persistent research platforms to ensure research continuity and cross-disciplinary collaboration, deliver/offer persistent services, with an adequate governance model The recent advancements in the general computer and big data technologies facilitate the paradigm change in modern e-science that is characterized by the following features: • Automation of all e-science processes, including data collection, ­storing, classification, indexing, and other components of the general data curation and provenance • Transformation of all processes, events, and products into digital form by means of multidimensional, multifaceted measurements, monitoring, and control; digitizing existing artifacts and other content • Possibility of reusing the initial and published research data with possible data repurposing for secondary research • Global data availability and access over the network for a cooperative group of researchers, including wide public access to scientific data • Existence of necessary infrastructure components and management tools that allow fast infrastructures and services composition, adaptation and provisioning on demand for specific research projects and tasks • Advanced security and access control technologies that ensure secure operation of the complex research infrastructures and scientific instruments and allow creating a trusted secure environment for cooperating groups and individual researchers The future SDI should support the whole data life cycle and explore the benefit of data storage/preservation, aggregation, and provenance on a large scale and during long or unlimited periods of time.
