Foreword This Technical Report (TR) has been
34、produced by ETSI Technical Committee GRID (GRID). The present document is part 2 of a multi-part deliverable covering the study of ICT GRID interoperability gaps, as identified below: Part 1: “Inventory of ICT Stakeholders“; Part 2: “Interoperability Gaps and proposed solutions“. ETSI ETSI TR 102 65
35、9-2 V1.2.1 (2009-10)81 Scope The present document selects and proposes solutions to the identified interoperability gaps in existing and emerging Grid standards. It identifies shortcomings, overlaps and loopholes in current, proposed, and de facto Grid standards at all levels of the middleware/proto
36、col stack (network to application interfaces), with specific consideration for large-scale commercialization and interoperability of standards/systems relevant to the ICT sector (i.e. the ETSI constituency), such as NGN and proposes solutions. The present document is part two of a multi-part deliver
37、able providing a study of ICT Grid interoperability gaps. The present document provides gap analysis and proposes solutions to the identified gaps. The gaps have been identified through analysis of a series of scenarios, a summary of which can be found in the appendices. By selecting common themes a
38、cross those scenarios it has been possible to identify specific requirements. These have directed the analysis of specific Grid standards. Standards identified may be Grid specific standards or other standards which support an integrated Grid NGN environment. The present document addresses: Interope
39、rability gaps in Grid Standards. Interoperability gaps between Grid and NGN standards in an integrated environment. The present document does not address: Interoperability gaps between different Grid infrastructures due to custom software packages. Interoperability gaps between two implementations o
40、f the same standard (e.g. shortcomings and lack of precision). TR 102 659-1 i.21 captures the current state of Grid technologies and identifies the key stakeholders, including standards making bodies, research projects, production Grids and other initiatives. Additionally, it identifies a recommende
41、d base of standards and de facto standards in the form of a Grid ICT Profile, taking into account the requirements for interoperability in the ICT domain. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
