DWDM-RAM: An Architecture for Data Intensive Service Enabled by Next Generati...Tal Lavian Ph.D.
Ā
An architecture is proposed for data-intensive services enabled by next generation dynamic optical networks. The architecture supports new data communication services that allow for coordinating extremely large sets of distributed data. The architecture allows for novel features including algorithms for optimizing and scheduling data transfers,methods for allocating and scheduling network resources, and an intelligent middleware platform that is capable of interfacing application level services to the underlying optical technologies. The significance of the architecture is twofold: 1) it encapsulates āoptical network resourcesā into a service framework to support dynamically provisioned and advance scheduled data-intensive transport services, and 2) it establishes a generalized enabling framework for intelligent services and applications over next generation networks, not necessarily optical end-to-end. DWDM-RAM1 is an implementation version of the architecture, which is conceptual as well as experimental. This architecture has been implemented in prototype on OMNInet, which is an advanced experimental metro area optical testbed that is based on novel architecture, protocols, control plane services (Optical Dynamic Intelligent Network-ODIN2), and advanced photonic components. This paper presents the concepts behind the DWDM-RAM architecture and its design. The paper also describes an application scenario using the architectureās data transfer service and network resource services over the agile OMNInet testbed.
DWDM-RAM: a data intensive Grid service architecture enabled by dynamic optic...Tal Lavian Ph.D.
Ā
The DWDM-RAM project develops an architecture for data-intensive grid services enabled by dynamic optical networks. It encapsulates optical network resources like wavelengths and lightpaths as grid services. This allows applications to schedule large data transfers using these network resources. The architecture consists of application and resource middleware layers. It is being implemented on the OMNInet photonic testbed to demonstrate on-demand and scheduled data retrieval using a dynamically switched DWDM network. In summary, DWDM-RAM schedules high-bandwidth network resources through dynamic lightpath provisioning and makes large-scale data services accessible via a grid service interface.
Localization as a service in an Intelligent Transport SystemSaber Ferjani
Ā
The problem of localization is a challenging task, and yet extremely crucial for many applications. While GNSS (such as GPS, or Galileo) solves the problem of localization for wide area of applications, the problem persists in many other cases like if satellite coverage is not available (skyscraper, tunnel), or the accuracy level is not sufficient. In such case, Invoking other devices and combining information from multiple sources may be considered as a potential solution.
Efficient IOT Based Sensor Data Analysis in Wireless Sensor Networks with Cloudiosrjce
Ā
This summary provides the key details from the document in 3 sentences:
The document proposes an efficient IoT-based sensor data analysis system in wireless sensor networks using cloud computing. It utilizes the Greedy Perimeter Stateless Routing (GPSR) algorithm to route sensor data to cloud storage. The system is evaluated through simulations analyzing parameters like packet delivery ratio, energy consumption, and delay.
In this presentation we review some of the research problems we address at EPFL in the area of sensor data management. At the level of infrastructure we have developed a middleware to seamlessly integrate, aggregate and analyze heterogeneous sensor data streams in real-time, a WIKI based repository supporting the cooperative management of the metadata associated with sensor deployments and cloud-based storage infrastructure. An important problem in managing sensor data is their efficient storage and transmission using compression techniques. To that end we apply model-based compression methods. For analyzing sensor data, we have developed methods to dynamically estimate the variability, which can be readily used for outlier detection, and to extract semantic features from GPS sensor data streams. We also investigate techniques for trading off between the accuracy of the sensor data obtained and the degree of privacy preservation that can be maintained.
The Sensor Data Management presentation was presented by Karl Aberer (Ecole Polytechnique Federale de Lausanne) at the PlanetData project Meeting on February 28 - March 4, 2011 in Innsbruck, Austria.

A NEW ALGORITHM FOR CONSTRUCTION OF A P2P MULTICAST HYBRID OVERLAY TREE BASED...csandit
Ā
In the last decade Peer to Peer technology has been thoroughly explored, because it overcomes many limitations compared to the traditional client server paradigm. Despite its advantages over a traditional approach, the ubiquitous availability of high speed, high bandwidth and low latency networks has supported the traditional client-server paradigm. Recently, however, the surge of streaming services has spawned renewed interest in Peer to Peer technologies. In addition, services like geolocation databases and browser technologies like Web-RTC make a hybrid approach attractive.

New approaches with chord in efficient p2p grid resource discoveryijgca
Ā
Grid computing is a type of distributed computing which allows sharing of computer resources through
Internet. It not only allows us to share files but also most of the software and hardware resources. An
efficient resource discovery mechanism is the fundamental requirements for grid computing systems, as it
supports resource management and scheduling of applications. Among various discovery mechanisms,
Peer-to-Peer (P2P) technology witnessed rapid development and the key component for this success is
efficient lookup applications of P2P. Chord is a P2P structural model widely used as a routing protocol to
find resources in grid environment. Plenty of ideas are implemented by researchers to improve the lookup
performance of chord protocol in Grid environment. In this paper, we discuss the recent researches made
on Chord Structured P2P protocol and present our proposed methods in which we use the address of
Recently Visited Node (RVN) and fuzzy technique to locate the grid resources to reduce message and time
complexity.
The document surveys real-time data management techniques for wireless sensor networks. It discusses the challenges of managing large amounts of real-time data in wireless sensor networks due to hardware constraints and limited resources. It describes two main approaches to data storage and querying: the warehousing approach where data is sent to a central database, and the distributed approach where sensor devices act as local databases. It then reviews several existing solutions that use each approach, including indexing techniques for centralized databases and distributed architectures using clustering or layers.
CONTENT BASED DATA TRANSFER MECHANISM FOR EFFICIENT BULK DATA TRANSFER IN GRI...ijgca
Ā
A new class of Data Grid infrastructure is needed to support management, transport, distributed access, and analysis of terabyte and peta byte of data collections by thousands of users. Even though some of the existing data management systems (DMS) of Grid computing infrastructures provides methodologies to handle bulk data transfer. These technologies are not usable in addressing some kind of simultaneous data
access requirements. Often, in most of the scientific computing environments, a common data will be needed to access from different locations. Further, most of such computing entities will wait for a common scientific data (such as a data belonging to an astronomical phenomenon) which will be published only
when it is available. These kinds of data access needs were not yet addressed in the design of data component Grid Access to Secondary Storage (GASS) or GridFTP. In this paper, we address an application layer content based data transfer scheme for grid computing environments. By using the
proposed scheme in a grid computing environment, we can simultaneously move bulk data in an efficient way using simple subscribe and publish mechanism.
New generations of applications call for new demands
that are totally different from previous uses of the Internet (e.g.,
cross-layer and network function virtualization), and the existing
networks are not optimized for these new demands due to being
overwhelmed by enormous numbers of external network
protocols. Overlay network technologies aim to respond to such
future network demands. Systems on overlay networks mitigate
this protocol overload by exploiting the unlimited
programmability of the overlay nodes comprising the system.
This paper proposes an overlay node that works as a transparent
proxy server and router for encrypted communication over
overlay networks. This overlay node acts as a virtual switch over
multiple layers of the OSI reference model (the datalink, network, transport, and session layers) using general-purpose components (a personal computer, physical network interface card, and
virtual network interface card, developed using the C language).
The ideas behind this proposal derive from the effectiveness of
software-defined networks and network function virtualization.
Finally, we examine the performance of the overlay node
experimentally and suggest possible designs for future overlay
networks.
Analysis of Link State Resource Reservation Protocol for Congestion Managemen...ijgca
Ā
With the wide spread of WiFi hotspots, concentrated traffic workload on Smart Web (SW) can slow down
the network performance. This paper presents a congestion management strategy considering real time
activities in todayās smart web. With the SW context, cooperative packet recovery using resource
reservation procedure for TCP flows was adapted for mitigating packet losses. This is to maintain data
consistency between various access points of smart web hotspot. Using a real world scenario, it was
confirmed that generic TCP cannot handle traffic congestion in a SW hotspot network. With TCP in
scalable workload environments, continuous packet drops at the event of congestion remains obvious. This
is unacceptable for mission critical domains. An enhanced Link State Resource Reservation Protocol (LSRSVP)
which serves as dynamic feedback mechanism in smart web hotspots is presented. The contextual
behaviour was contrasted with the generic TCP model. For the LS-RSVP, a simulation experiment for TCP
connection between servers at the remote core layer and the access layer was carried out while using
selected benchmark metrics. From the results, under realistic workloads, a steady-state throughput
response was achieved by TCP LS-RSVP to about 3650Bits/secs compared with generic TCP plots in a
previous study. Considering network service availability, this was found to be dependent on fault-tolerance
of the hotspot network. From study, a high peak threshold of 0.009 (i.e. 90%) was observed. This shows
fairly acceptable service availability behaviour compared with the existing TCP schemes. For packet drop
effects, an analysis on the network behaviour with respect to the LS-RSVP yielded a drop response of about
0.000106 bits/sec which is much lower compared with the case with generic TCP with over 0.38 bits/sec.
The latency profile of average FTP download response was found to be 0.030secs, but with that of FTP
upload response, this yielded about 0.028 sec. The results from the study demonstrate efficiency and
optimality for realistic loads in Smart web contexts.
This document summarizes a research paper that proposes CafRep, an adaptive congestion control protocol for delay-tolerant networks (DTNs). CafRep uses implicit heuristics based on contact and resource congestion to offload traffic from congested parts of the network to less congested areas. It also adaptively replicates messages at lower rates in different parts of the network with non-uniform congestion levels. The paper evaluates CafRep across three real mobility traces and shows it outperforms state-of-the-art DTN forwarding algorithms in maintaining high delivery rates while keeping low delays and packet loss, especially in congested networks.
Survey on Synchronizing File Operations Along with Storage Scalable MechanismIRJET Journal
Ā
The document summarizes research on efficient file operations and storage scalability mechanisms. It discusses how data is divided into chunks and distributed to nodes for transmission in peer-to-peer networks. The proposed system aims to provide efficient load balancing, eliminate single points of failure, and ensure synchronization and security during data transmission. It uses synchronization algorithms and a hybrid distribution model combining features of peer-to-peer and client-server networks. The system is designed to securely handle insertions, deletions, splits, and concatenations of file chunks in a distributed storage system.

The past decade has seen increasingly ambitious and successful methods for outsourcing computing. Approaches such as utility computing, on-demand computing, grid computing, software as a service, and cloud computing all seek to free computer applications from the limiting confines of a single computer. Software that thus runs "outside the box" can be more powerful (think Google, TeraGrid), dynamic (think Animoto, caBIG), and collaborative (think FaceBook, myExperiment). It can also be cheaper, due to economies of scale in hardware and software. The combination of new functionality and new economics inspires new applications, reduces barriers to entry for application providers, and in general disrupts the computing ecosystem. I discuss the new applications that outside-the-box computing enables, in both business and science, and the hardware and software architectures that make these new applications possible.
The document discusses grid computing and the development of computational grids. Key points:
- Grids allow for sharing of computing power and resources across geographic locations through networked supercomputers, databases, and instruments.

From Natural Language to Structured Solr Queries using LLMsSease
Ā
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or ācognitiveā gap) remains between the data user needs and the data producer constraints.
That is where AI ā and most importantly, Natural Language Processing and Large Language Model techniques ā could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr indexās metadata.
This approach leverages the LLMās ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

6. Triana environment is used for problem solving and
orchestrating flows of operations/services
=> fine-grained dataflow applications
=> course-grained distributed workflow system
Workflow is implicit in scientific algorithms that specify:
ļ§ a series of inter-dependent operations to be executed,
ļ§ connecting such algorithms in a series of derivations,
=> when aggregated perform some higher-level task
eLiberatica 2007
May 18-19, 2007 Brasov, Romania
7. Workflows can be:
ā¢ simple => contain a few components
ā¢ complex => logic-based support can be integrated to
make intelligent decisions about the dynamic evolution of
the particular workflow
Tasks with inter-dependencies expressed and handled by a
computation flow
ā the chain of elementary tasks are not necessarily linear
ā request a graph of interconnected tasks
Workflow management is data driven:
ļ§ the scientific experiments need to process large datasets
ļ§ the scheduler responsible for distributing the
computational load should take into account the
input dataset as well as the workflow graph topology

three years and many projects have used this combination to
specify their distributed course-grained service workflows
http://www.wspeer.org/
WSPeer - existing middleware which provides:
ā¢ a SOAP messaging layer (using Web Services / WS-RF)
ā¢ within a P2P network that supports a super-peer topology of
rendezvous or advert caching peers
=>to support the scalability of the discovery & access to information
=>to cache application-specific data, scientific data & metadata
(not just discovery information)
ļµ P2PS has been used as the underlying P2P environment
during this time
http://www.trianacode.org/p2ps/

14. Triana Focus
ļµ Two core underlying focuses:
ā¢ Interactive graphical programming of the
distributed tasks - complex editing
ļµ Intuitive drag/drop flexible editing - copy/paste services,
wizards for creating tools/toolboxes, user interfaces,
adding nodes and multi-level grouping.
ļµ Has been used as a āgraphical editorā for other languages,
e.g. DAG, VDLx (DAX in progress).
ā¢ Heterogeneous workflows - Bridge the gap between
different distributed environments
ļµ Use cross-environment interfaces
ļµ led to integration with GAT (pre SAGA), GAP

15. Triana allows to spontaneously create and run data analysis
algorithms on the data at its source.
ļ± Such a component-based object-oriented approach allows
scientists to easily create new algorithms that conform to an
agreed and defined set of data types and can adapt to
different internal parameters
ļ± Makes it easy to create individual user interfaces for each
component to allow the modification of its internal parameters
ļ± Graphical approach
=> REUSABILITY of existing units
=> Allows simple type-safe orchestration of data analysis
pipelines on-the-fly without the need for code-level
reconfiguration.
Triana enables project scientists to design and create systems
than connect together a number of software components.

25. Alchemist Workflows
and Data Discovery
for
Biomedical Research
eLiberatica 2007
May 18-19, 2007 Brasov, Romania
26. ļµ Alchemist infrastructure provides an innovative
mechanism for biomedical image data search and
spectral data discovery
ā¢ metadata generated from user and automatic
annotations is fused
ā¢ semantics can be included as part of the query
ļµ Triana - as a scientific workflow environment -
has been used in Bioinformatics projects as the
Grid-based problem-solving environment for collaborative
exploration and analysis of global biodiversity patterns
eLiberatica 2007
May 18-19, 2007 Brasov, Romania
27. Within the context of Biomedical sciences, the Alchemist
has a significant potential to support:
(i) distributed biomedical communities focused on a specific
disease process
(ii) disease-oriented collaborative studies which share large
datasets
(iii) integrative biology projects that need to analyse inter-
related information at different levels
(e.g. clinical, cellular, molecular and genomic)
(iv) population-based studies (e.g. clinical trials in diabetes or
cancer)
eLiberatica 2007
May 18-19, 2007 Brasov, Romania
28. For biomedical images, current practice usually involves searching
databases containing:
(i) patient data repositories
(ii) case-oriented reference atlases (i.e. dynamic information across
spatial and temporal scales of abstraction)
(iii) training collections (documented biomedical images, either
anonymised individual or averaged data and training datasets)
Biomedical audio-visual content and associated metadata can be
discovered and retrieved, allowing also the visualization of
particular regions of interest within the images, or anomalies in
the patterns of spectral data.
While content-based retrieval is an active field of research, multiple
modality search (using data from multiple sources and media,
and data from different levels of biological organisation) can give
deeper insights into the nature of biological entities and the
processes they are involved in.
eLiberatica 2007
May 18-19, 2007 Brasov, Romania
29. By using the Alchemist for disease-oriented studies,
P2P caching could support the search, selection and aggregation
of similar biomedical and spectral datasets.
=> Caching, using rendezvous peers (as in WSPeer), can be
adapted to cache similar requests for resources
=> store hits on nodes which are within closer proximity to
the particular group of researchers interested in the file
eLiberatica 2007
May 18-19, 2007 Brasov, Romania
30. Mobile support is also provided for the Alchemist
infrastructure
ļ§ Clinicians can benefit greatly from the possibility of using a
mobile device to initiate search operations, retrieve medical
audio/visual data and associated records, or operate data
transfer between different static repositories, in a controlled
and secure way.
ļ§ We also address the possibility of using mobile devices for
workflow management by the remote control of the
enactment engine from a mobile user interface, for the data
fusion of different kinds of data and metadata and the
integration of algorithms designed under a common problem-
solving environment
