The PEPPOL project aims to enable EU-wide public eProcurement by establishing an infrastructure for businesses to communicate electronically with any European contracting authority. It involves 18 beneficiaries from 12 countries working on 8 work packages over 4 years with a budget of 30.8 million euros. The PEPPOL vision is for any supplier in the EU, including SMEs, to be able to communicate electronically with any European contracting authority for all procurement processes. A 5-stage progress plan outlines building the PEPPOL community from basic components in 2010 to universal adoption after 2012. The PEPPOL infrastructure uses specifications for components like registries and transport protocols to allow participants to locate and exchange messages with each other across Europe in a standardized way.

IMPACT OF CONTENTION WINDOW ON CONGESTION CONTROL ALGORITHMS FOR WIRELESS ADH...cscpconf
TCP congestion control mechanism is highly dependent on MAC layer Backoff algorithms that
predict the optimal Contention Window size to increase the TCP performance in wireless adhoc
network. This paper critically examines the impact of Contention Window in TCP congestion
control approaches. The modified TCP congestion control method gives the stability of
congestion window which provides higher throughput and shorter delay than the traditional TCP. Various Backoff algorithms that are used to adjust Contention Window are simulatedusing NS2 along with modified TCP and their performance are analyzed to depict the influence of Contention Window in TCP performance considering the metrics such as throughput, delay, packet loss and end-to-end delay
Network Policy Abstractions in OpenStack NeutronSumit Naiksatam
A new set of application centric network abstractions are being developed in the form of the Neutron Group Policy extension. In this model, networking requirements of applications are expressed as network policies. On the other hand, there have been significant work on defining network services (*aaS), service insertion and service chaining in the Neutron community. More recently work on Network Function Virtualization and a framework for advanced services in virtual machines have been getting attention.
In this talk, we first discuss the state of the work in implementing the Neutron Group Policy extension and show how a more application-centric view of networking resources can be used to specify and deploy applications. In particular, we demonstrate the use of network policies as defined in a Heat template to specify and deploy an application. We then explore how the Neutron Group Policy extension can take advantage of advances in defining network services and functions and bring about a truly application centric view of networking resources. We show how this view impacts different layers of the stack from end to end and discuss the future directions of the Neutron Group Policy extension.

In the growing trend of technology, it is important to keep up with user expectation and his level of satisfaction. Thus, there is high demand for Quality of Experience (QoE) in the research domain. The Quality of Experience is defined as the degree of delight or annoyance of the user of an application or service. It results from the fulfillment of his or her expectations with respect to the utility and/or enjoyment of the application or service in the light of the user’s personality and current state. In the context of communication services, it is influenced by content, network, device, application, user expectations and context of use.QoE is a subjective measure whereas QoS is objective. Thus, it is interesting to analyze the behavior of QoE rather than QoS.
Capacity charging mechanism for shared CO2 transportation and storage infrast...Global CCS Institute
While technical and legal barriers to CCS are diminishing, the difficulty in building a sound commercial case for the development and operation of CCS infrastructure remains a serious obstacle. One way to significantly reduce the cost of CCS is to realise economies of scale by sharing a single CO2 transportation and storage infrastructure system among several operators of CO2 capture plants.
This webinar, presented by Calum Hughes, Director - CCS at Yellow Wood Energy and Dave Bevan, Commercial Developer at National Grid Carbon (UK), will provide insight into the commercial charging mechanism developed by National Grid for a shared CCS infrastructure system. In particular, various options for allocating system development and operational costs between members of an infrastructure network will be explored.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. The PEPPOL project The PEPPOL project is the result of the European Competitiveness and Innovation Programme (CIP) ICT Policy Support Programme (ICTPSP) 2007 and 2009 Call for Proposals Pilot A objective: Enabling EU-wide public eProcurement 50% EU contribution for achieving interoperability Coordinated by the Norwegian Agency for Public Management and eGovernment (Difi) Consortium and scope: 18 beneficiaries from 12 countries Total budget 30,8 M€ 8 work packages, <1.600 person months and 10 M€ on sub-contractors Project start up: 1 May 2008, duration 48 months* *Current project duration is 42 months (+6 months extension subject to European Commission's approval)
3. Any supplier (incl. SMEs) in the EU can communicateelectronically with any European contracting authority for all procurement processes. The PEPPOL Vision 3
5. Progress plan for building the PEPPOL community READY: Since May 2010, basic PEPPOL components and services are in place for a limited number of invited test pilot participants. PROVEN: From now until mid 2011, a growing number of production pilots create an integrated community between PEPPOL consortium members, using PEPPOL to perform real business. Recruitment of non-PEPPOL consortium members as pilot participants evolves. IN USE: By the end of 2011, we will have a substantial number of pilots performing real business through PEPPOL among both PEPPOL and non-PEPPOL consortium members. ESTABLISHED: By mid 2012, the PEPPOL Community expands beyond those recruited by PEPPOL to recruitment by commercial market driven adoption. UNIVERSAL: After mid 2012, a critical mass of adoption sees PEPPOL used by a majority of eProcurement communities across Europe. Page 5

9. BusDox – the specifications behind the PEPPOL infrastructure SMP (registry) – Describes how a registry should be accessed and what infromation needed to be exposed. The SMP is a service registry, not a traditional partner capability registry. SML(registry/service locator) – Describes how the interface against the DNS works. The SML is used to add/update/delete information about the registry in where a particular participant is located START(transport protocol) – Describes how the message exchange is performed in a reliable and secure way using web services. LIME(transport protocol) – Describes how a accounting system/E-invoicing system connects to a service provider. A bit like the POP3 protocol for emails (look for a list of document, download received documents, upload documents)

19. The PEPPOL Governance Model The basis for PEPPOL is that national infrastructures exist and will continue to exist also in the future (In addition, privately operated e-procurement communities exist within and across borders) The objective of PEPPOL is to provide interoperability between existing solutions so that “any supplier (incl. SMEs) in the EU can communicate electronically with any European contracting authority for all procurement processes”. The specifications and technology used by PEPPOL may be candidate solutions for domestic adoption/recommendation The proposed governance model for the PEPPOL transport infrastructure respects this basis and is thus built around two levels of coordination: The European wide coordination providing governance over all common components of the transport infrastructure. The regional coordination providing governance over the implementation and use of the transport infrastructure within a domain.
20. Regional domain Regional domain AP AP Contracting Authority Economic Operator SMP SMP SML Coordinating Authority Regional Authority Two levels of governance Provides European wide governance for: the PEPPOL Technical Standards the PEPPOL Service Specifications the PEPPOL SML the PEPPOL Agreements Provides regional governance for: the implementation and use of the transport infrastructure the legal framework for specific AP and SMP agreements specific requirements applicable within a domain
21. Page 18 The PEPPOL Transport Infrastructure Agreements
22. PEPPOL Transport Infrastructure Agreements The aim of the PEPPOL Transport Infrastructure Agreements is to regulate the roles and responsibilities of the actors involved in the governance and operation of the PEPPOL transport infrastructure. Three separate agreements with a common set of annexes. Contact points Definitions Service and Service Levels Technical Standards Regional domain and its specific services and service levels Change Procedures The PEPPOL Governance Model and model agreements
23. Key principles Inspired by other initiatives, but reflects the uniqueness of the PEPPOL initiative: An open community where interoperability is achieved through common specification and not point-to-point agreements. The PEPPOL Transport Infrastructure Agreements provides governance for the PEPPOL Transport Infrastructure based on: a European wide coordination over all common components of the transport infrastructure; a regional coordination and supervision of the implementation and use of the transport infrastructure within a domain; and open and transparent provision of SML, SMP and AP services based on a common set of agreements as well as common definition of services and service levels.
24. PEPPOL Transport Infrastructure Agreements PEPPOL Community Agreement “… terms and conditions under which the Parties shall provide governance for the PEPPOL Transport Infrastructure.” A model agreement regulating the “… terms and conditions under which: the PEPPOL AP Provider shall provide the required PEPPOL AP Services; the PEPPOL Regional Authority shall ensure that the services provided by the PEPPOL AP Provider are provided and maintained in a reliable, professional and state of the art manner, in compliance with all applicable laws and all relevant technical specifications, to ensure consistency across the full PEPPOL Transport Infrastructure .” A model agreement regulating the “… terms and conditions under which: the PEPPOL SMP Provider shall provide the required PEPPOL SMP Services; the PEPPOL Regional Authority shall ensure that the services provided by the PEPPOL SMP Provider are provided and maintained in a reliable, professional and state of the art manner, in compliance with all applicable laws and all relevant technical specifications, to ensure consistency across the full PEPPOL Transport Infrastructure.” PEPPOL AP Provider Agreement Coordinating Authority I.e.
