CFP: NetCloud2012 - The 2nd workshop on Network Infrastructure Services as part of Cloud Computing (3-6 December 2012, Taipei, Taiwan)
by Yuri Demchenko 09 Jul '12

09 Jul '12

Apologies for cross-posting. This is a good chance to expose our work to the AP region. The CloudCom2012 conference (http://2012.cloudcom.org/) features a number of workshop with majority of regional participants. ----------- CFP NetCloud2012 -------------- The 2nd workshop on Network Infrastructure Services as part of Cloud Computing (NetCloud 2012) 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. Important Dates: Paper Submissions: August 10, 2012 Notification: September 7, 2012 Camera-ready: September 28, 2012 Paper submission instructions This workshop will only accept for review original papers that have not been previously published. Papers should be formatted based on the IEEE Transactions journals and conferences style; maximum allowed camera-ready paper length is six (6) pages. Submissions must be in Adobe PDF format, including text, figures and references. Accepted papers will be published in the CloudCom2012 proceedings, for further information see IEEE CloudCom 2012 web page http://2012.cloudcom.org/. Review procedure All submitted paper will be reviewed by international program committee. Workshop Organizers The workshop is organized by the partners of the GEYSERS, the EC-funded FP7 project.

Determining the Network of an STP
by Freek Dijkstra 06 Jul '12

06 Jul '12

During today's call, Jerry brought up the following issue: (Jerry, please correct me if I'm wrong, and sorry if I mixed up the NSI with the NML terminology). A path computation engine needs to know in which domain a STP lies. There are solutions to this: 1. The domain can be inferred by parsing the URN identifier of the STP. 2. Each domain announces a full list of it's STPs, and the path computation engine keeps a table of all STP-Domain relations. 3. Each connection request must not only list the URN of the STP, but the URN of the domain as well. The current solution is (1), but that conflicts with the choice in NML that a URN may not contain the domain identifier and should not be interpreted/parsed. Solution (2) or (3) do not have this drawback. Solution (2) seems less scalable compared to solution (3). Regards, Freek

Re: [Nsi-wg] NSI Paper
by Jeroen van der Ham 01 Jul '12

01 Jul '12

Hi all, I don't have a fully crystalized version of the ToC yet, but my general idea was to use the journal paper to summarize the Terena paper as an introduction and general description of the NSI work. Then I'd like to spend a bit more space to the testbed, and results from the test-bed so far. And finally I hope to get a bit more specific about NSI v2.0 to discuss as conclusion and future plans.
