Two meanings are associated with this state: 1. All child NSAs have acknowledged receipt of the provision command 2. All child NSAs have confirmed provisioning complete Discussion of Issue: Should we refine the state-machine to disambiguate these two different understandings of 'Provisioned'. A proposal has been made to add a new message 'Connection-State up'. Resolution of Issue:

Status: Accepted Owner: jmacau...(a)gmail.com Labels: Type-Defect Priority-Medium FoundInVersion-1.0 FixedInVersion-1.1 New issue 63 by jmacau...(a)gmail.com: Query: Need to include requester NSA information associated with a connection reservation. http://code.google.com/p/ogf-nsi-project/issues/detail?id=63 Description of Issue: When using the Query operation there is no way to determine within the QueryConfirmed the requester NSA associated with a connection reservation. This means there is no way to determine the direct parent NSA associated with a reservation. Discussion of Issue: It was agreed in the week meeting that the requesterNSA should be returned with the query result for both summary and detailed results. Resolution of Issue: RequesterNSA should be returned with the query result for both summary and detailed results.

Comment #2 on issue 39 by jmacau...(a)gmail.com: STP syntax http://code.google.com/p/ogf-nsi-project/issues/detail?id=39 I am confused by this agreement. An STP is defined as a OGF URN that is composed of the NSnetwork and localId already. Is this asking me to break out the STP into two discrete elements?

CFP: NetCloud2012 - The 2nd workshop on Network Infrastructure Services as part of Cloud Computing (3-6 December 2012, Taipei, Taiwan)
by Yuri Demchenko 31 Jul '12

31 Jul '12

Apologies for cross-posting. Submission website is open > https://www.easychair.org/conferences/?conf=netcloud2012 CFP link > http://www.geysers.eu/index.php/newsandevents/49-events/139-netcloud2012-wo… The CloudCom2012 conference (http://2012.cloudcom.org/) features a number of workshop with majority of AP regional participants. P.S. The Organising Committee is considering deadline extension for 2 weeks but this will be confirmed later. ----------- CFP NetCloud2012 -------------- The 2nd workshop on Network Infrastructure Services as part of Cloud Computing (NetCloud 2012) http://www.geysers.eu/index.php/newsandevents/49-events/139-netcloud2012-wo… In conjunction with the 4th IEEE International Conference on Cloud Computing Technology and Science (CloudCom2012) http://2012.cloudcom.org 3-6 December 2012, Taipei, Taiwan Introduction The workshop is a follow-up of the first successful workshop in 2011, where a number of enthusiasts of cloud computing and future networking exchanged ideas and presented results of research projects dealing with clouds and network integration. The Cloud computing emerges as a new computing paradigm which aims to provide secure and reliable, on demand QoS guaranteed computing environments for the end-users. Cloud computing services usage in both academia and industry, changed the way of thinking on how users’ needs can be satisfied by computational infrastructures. However, with the increase of data transferred among different places, it became critical how to support distributed computing resources with advanced network infrastructure services. It is envisioned that network infrastructure services provisioned on-demand could be managed and reconfigured dynamically by Cloud operators and user applications to achieve optimal usage criteria. Such dynamic infrastructures reveal new aspects in network virtualisation, service delivery automation and general infrastructure resources management that should be supported by well-defined information models and related middleware. New components of the required network infrastructure for Cloud services and applications should create an integrated self-management environment that can react to changes in workloads and other events with minimal human interference. Security issues should addressed as a part of the general service delivery framework/workflow and support both infrastructure provisioning process and secure virtualised services/infrastructures operation. The workshop will address issues of network virtualisation to create an ecosystem for cloud computing applications. In particular, the workshop will discuss the progress of development of advanced tools and mechanisms for seamless and efficient integration of network and IT worlds, not well interconnected so far. The workshop will consist of a number of sessions, where recent results of on-going and just-finished research projects will be demonstrated. The workshop will present also some future research considerations on the future of cloud computing and networking and expose views from different perspectives: research projects and industry. The workshop will be followed by a panel discussion, to allow free exchange of thoughts and ideas between the workshop speakers and audience. Objectives NetCloud 2012, collocated with IEEE CloudCom 2012, attempts to address the problem of how the underlying network infrastructure is capable of supporting advanced cloud computing cases. The workshop is intended to bring together network research community, commercial network operators and industry with the major cloud computing players, including IT specialists, researchers and commercial providers. Topics of Interest * Definition and architectures for the Network as a Service (NaaS) cloud service model and Cloud Carrier operational model * Heterogeneous network architectures and frameworks for distributed and high performance computing * Cloud and Intercloud architecture frameworks and required on-demand network infrastructure provisioning * Unified and converged IT and optical resources description languages and frameworks for cloud oriented infrastructures * General Infrastructure services provisioning in clouds, new architecture developments, service delivery and on-demand provisioning frameworks * Isolation and flexibility of the cloud oriented virtualised optical networks * Network infrastructure optimization for intra- and inter- datacenter communication and resources virtualisation * Standardization of optical network service provisioning interfaces for cloud based platforms and services * Co-advertisement, co-planning, composition and co-provisioning of any type of optical network resource and IT services (i.e. connectivity + IT resources at the end-points coordinated in a single, optimal procedure) * Performance and reliability issues, Service Level Agreement and QoS guarantees in the network layer * Dynamically provisioned security infrastructure and its integration with provider and customer legacy services and service provisioning workflow, security policy definition, security context management * End-to-end techniques for autonomic management of cloud resources * Policy based infrastructure services management * Experimental platforms that support network management in cloud computing * Experimentation test-beds and measurement studies Call for papers: Papers describing original research on both theoretical and practical aspects of dynamic network services for cloud computing are solicited.

Security discussion - document summarizing the state
by Inder Monga 25 Jul '12

25 Jul '12

Please continue the text only discussion on Skype. If anyone wants to be on the skype session, and is not, please let me know. The attached document captures the new compromised proposal - what Chin described on the call this morning, along with the background on the main disagreements so far. What we really need is for folks to check with their security officers and get a sanity check on the new proposal to ensure we do not make a security profile that will not stand the test of production level security. Thanks, Inder
