Common use of Update for D6 Clause in Contracts

Update for D6. 2bis At the time of writing this update, the first two entries in the above table have become of less relevance to the COSIGN consortium. The first, ETSI Grid and Cloud Computing has stopped to be active publishing new developments and goals. The second, ETSI Next-Generation Network has stabilized on its focus on evolution towards 5G and is not currently impacting the DCN developments. The ETSI NFV ISG and all of its WGs are very active and of great relevance to COSIGN. Although the driving use cases and the majority of ETSI NFV focus are in Telco networks, data centre, and thus COSIGN, the relation is obvious. The COSIGN consortium will therefore continue to follow the activities of this ISG and its publications, looking for opportunities to present COSIGN ideas and outcomes to the ISG members and influencers. The IBM team participating in COSIGN follows the group and its results – documentation, white papers, proofs of concepts. Due to team’s Data Centre focus, it cannot commit to attending the meetings and/or giving presentations there. NXW is participant and observing member - non voting - in ETSI NFV ISG and, as such, the team involved in COSIGN is following the latest NFV outcomes about architectural specifications of the Virtual Infrastructure Management and Orchestration components. Their impact on DC requirements and functionalities will be continuously analysed and taken into account in COSIGN architectural choices for network control and cloud orchestration. The updated ETSI liaisons plan is summarised in Table 3: ETSI Standardization element Type of Interaction Schedule Priority Partners NFV ISG; Architecture of the Virtualisation Infrastructure Defining architectural role of virtual network functions as part of overall data centre IT and network resources.

Update for D6. 2bis At The IETF I2RS WG has been defining an interface towards the time routing system with the objective of writing enabling unified mechanisms for the distribution of information about network topology and network status. In this updateframework, the first two entries WG has continued to be very active with recently updated Internet Drafts defining YANG models for the description of a generalized network topology [28], as well as X0 [00] and X0 [00] network topologies. Moreover, a novel individual Internet Draft, published in March 2015, is also addressing the YANG model for a L1 network topology [31]. NXW is following these activities to ensure the standard alignment of the topology services developed as OpenDaylight plugins in WP3. If needed, NXW will participate in the above table have become of less relevance WG mailing list discussions in order to contribute with the COSIGN results to the standardization work in this area, with particular focus on the modelling of optical network topologies, evaluating the possibility of submitting contributions to the related Internet Draft. The applicability of PCE concepts to SDN environments is currently investigated in the IETF PCE WG, through an Internet Draft which discusses the usage of PCE as a Central Controller [32]. This concept is strongly related to the path computation functions which will be implemented in the COSIGN SDN controller, so NXW and UPC teams will follow up on the WG results in order to guarantee the consistency of COSIGN path computation components with the related standard in terms of architectural splitting, interfaces and information models. The main relevance of the IETF NETMOD WG for COSIGN is related to the definition of YANG models for a variety of network aspects, including management or control services. The COSIGN consortium, and in particular the WP3 team, will monitor the WG results in order to identify YANG models (or part of them) which can be integrated or used as starting point in the OpenDaylight plugins developed to implement the COSIGN SDN controller functions. The firstteam will also consider proposing the standardization of COSIGN-specific augmentations of existing YANG models (e.g. dealing with optical resources or optical connection constraints), ETSI Grid where relevant for the whole WG scope. IETF work related to overlay network virtualization – IETF NVO3 and Cloud Computing has stopped to be active publishing new developments and goals. The second, ETSI Next-Generation Network has stabilized on its focus on evolution towards 5G and SFC WGs – is not currently impacting the DCN developments. The ETSI NFV ISG and all of its WGs are very active and of great relevance continues to be relevant to COSIGN. Although This year IETF SFC WG has finalized the driving problem statement document (RFC 7498) and is actively progressing towards finalizing the use cases and architectural approaches. Specifically, IETF community works together with IESG to finalize the majority of ETSI NFV focus are in Telco networks, data centreService Function Chaining (SFC) Architecture, and thus COSIGNa draft has been updated very recently which describes an architecture for the specification, creation, and ongoing maintenance of SFC in a network, as well as components used in the relation is obviousconstruction of composite services through deployment of SFCs. The COSIGN consortium will therefore IBM and UNIVBRIS continue to follow up on the activities of this ISG developments by periodically reviewing the published and its publicationsupdated RFCs. The IETF NVO3 WG is more advanced and is currently exploring the solution space, looking for opportunities to present COSIGN ideas after publishing the problem statement (RFC 7364) in July 2013 and outcomes to the ISG members and influencersframework program (RFC 7365) one year later. The IBM team participating in COSIGN follows continues to follow up on the group WG’s mailing list. The COSIGN WP6 team continues to monitor the broader scope of IETF/IRTF activities watching for developments relevant to our work. In this area the following new liaison candidates have been identified: • IETF Bmwg WG – Benchmarking Methodology – is developing a document investigating benchmarking related to network functions virtualization and its results infrastructures where these virtual functions are deployed (draft-ietf-bmwg-virtual-net) • IETF Xxxx XX – documentation, white papers, proofs BGP Enabled Services – is actively exploring the possibility of conceptsemploying eVPN technology in the control plane of tunneling-based overlays (e.g. draft-ietf-xxxx-evpn- overlay). Due to team’s Data Centre focus, it cannot commit to attending the meetings and/or giving presentations there. NXW is participant • Network Function Virtualization Research Group (NFVRG) was charted on 2015-1-20 and observing member - non voting - in ETSI NFV ISG and, as such, the team involved in COSIGN is following the latest NFV outcomes about architectural specifications of the Virtual Infrastructure Management and Orchestration components.

The COSIGN dissemination activities target a wide audience of the academic and the industrial communities in areas of optical communications, data centres, and clouds, spanning from individual researchers and developers to providers and users. The project consortium will be active in publishing the major scientific results in international journals and conferences. In addition, the project will be present in key events like workshops and special sessions or panels at international conferences. Dedicated workshops may be considered, potentially in cooperation with other related EU projects and research initiatives. The involvement in standardization activities in the SDN technical area (e.g. in IETF or ONF), led by partners already active in these SDOs, will be a key point to increase the visibility of the COSIGN concepts and the impact of the project outcomes. A plan with potential contributions for target SDOs has been defined and presented in this document.
