minutes from today's NSI conference call
by Guy Roberts 12 May '10

12 May '10

The minutes from today's conference call are available here: http://forge.gridforum.org/sf/go/doc15975?nav=1 The main issues that I would like to get general agreement on is the use of unidirectional vs. bidirectional connection requests. In the discussion we have proposed that NSI version 1.0 will support both uni and bi directional connection requests. Any comments on this proposal should be directed to the mailing list or discussed on next week's call.

describing segmentation function as use cas
by John Vollbrecht 12 May '10

12 May '10

Attached is a first cut at a doc that breaks segmentation into a use case for the NSI. I talked briefly with Guy about this and he suggested I send it to the group so we could talk about it this morning if we have time. John

11 May '10

*GRIDNETS 2010* 4th International ICST Conference on Networks for Grid Applications 13-15 September 2010, Chicago, USA www.gridnets.org <http://gridnets.org> *CALL FOR PAPERS *** DEADLINE EXTENDED*** * *SPONSORS* Sponsored by ICST <http://www.icst.org> Technically co-sponsored by CREATE-NET <http://www.create-net.org> *** *SCOPE* GRIDNETS 2010 provides a focused and highly interactive forum where researchers and technologists have the opportunity to present and discuss leading research, developments, and future directions in the Grid Networking area. The goal of this event is to serve as both the premier conference presenting best Grid Networking research and a forum where new concepts can be introduced and explored. *** ***TOPICS* **Topics of interest include but are not limited to the following focus areas:** ** * Network architectures and technologies for grids * Integration of advanced optical networking technologies into the grid environment * The network as a first class grid resource: network resource information publication, brokering, and co-scheduling with other resources * Interaction of the network with distributed data management systems * Network monitoring, traffic characterisation, and performance analysis * Inter-layer interactions: optical layer with higher layer protocols, integration among layers * Experience with pre-production optical network infrastructures and exchange points * Peer-to-peer network enhancements applied to the grid * Network support for wireless and ad hoc grids * Data replication and multicasting strategies and novel data transport protocols * Cluster and high performance networks * Networks for data centers * Networks & cloud computing issues * Fault-tolerance, self healing networks * Security and scalability issues when connecting a large number of sites within a virtual organization VPN * Cloud networking and Grid Networking intersection * Grid Networking and petascale computing * Grid Networking for e-Science * Terabit Grid Networking * Digital media and Grid Networks * Energy awareness and power consumption in grids * Virtual networks * Digital media networks * Ad hoc networks The organizers of GRIDNETS 2010 encourage submissions related to the results of future network research activities. Currently, many large scale advanced networking research projects have been established to create new types of experimental research environments, such as the US National Science Foundation's Global Environment for Network Innovations (GENI), those being created in Europe through the EIFFEL (Evolved Internet Future for European Leadership) and FIREworks (Future Internet Research and Experimentation - Strategy Works) initiatives, in Japan through the New Generation Internet program, and in many other countries. In addition, various related initiatives, such as the NSF's Future Internet Design (FIND), have been established to support research using advanced network research testbeds. GridNets has been designed as a forum in which the results of such activities can be presented and discussed. *** *PUBLICATION* Accepted papers will be published by Springer in the Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering <http://www.springer.com/computer?SGWID=0-146-6-564009-0> (LNICST) series. *** *SUBMISSION* Detailed submission and formatting instructions are available at http://gridnets.org/submission.shtml *** *IMPORTANT DATES* Papers submission deadline:*** 31 May 2010 (extended, firm deadline)* **Notification of paper acceptance:** *5 July 2010* **Camera-ready deadline:** *2 August 2010 ****** *ORGANIZING COMMITTEE* *General Chairs *Chair: Joe Mambretti, Northwestern University, USA Co-chair: Gigi Karmous-Edwards, North Carolina State University, USA* TPC Co-Chairs *Robert Grossman, University of Illinois, Chicago, USA Dimitra Simeonidou, University of Essex, UK For a complete list of committee and board members, please visit http://gridnets.org/committees.shtml *** *DISCLAIMER* ICST will only send e-mail of an informative character towards its carefully selected users based on their predefined areas of interest. ICST does not use volume-based mailing systems.

Hi All, Please find the minutes for this week's NSI conference call here: http://forge.gridforum.org/sf/go/doc15974?nav=1 A summary of agreed features for rel 1.0 advance reservation is attached below. Guy Issue v1.0 status Comments Synchronization of Provider/requester timers? Required agreed NTP should be ok, but not mandated 1 or 2 phase commit? 1PC agreed 2PC is considered unnecessary for v1.0 Is automatic provisioning (initiated by timer) required? Yes agreed Is explicit provisioning (initiated by requester message) required? Yes agreed Is advance reservation required? Yes agreed Is immediate reservation required? Yes agreed May need to update architecture text Allow ASAP as start-time for immediate reservation? Yes agreed How is advance distinguished from immediate reservation? Immediate uses 'ASAP' in the start-time field agreed What does start-time mean as used in protocol for auto mode? In-service begin time agreed It is the responsibility of the provider NSA to make sure that this in-service start time is met What does start-time mean as used in protocol for explicit mode? Time at which the provider is able to accept a provision signal agreed It is now the requestor's responsibility to advance the explicit signal to ensure good in-service time. What does end-time mean as used in protocol for explicit mode? End of reservation agreed What does end-time mean as used in protocol for advance reservation? In-service end time. This is the same as beginning of de-provisioning time agreed Is a tear-down signal required? Yes agreed Is connection duration required? May be required for ASAP start time Duration would replace end time. Is unspecified end-time allowed? No agreement on this point Provider validation of start time ? Validated agreed This is a constraint in path finding Is a flag necessary to indicate immediate vs. advance reservation No agreed Not necessary, immediate is indicated with 'ASAP' start-time. See flag below. Is a flag needed to indicate whether start-time later than specified guard is allowed? Yes agreed These start times are treated as 'now' and warning may be sent back to the Requester NSA. Does each Connection request need a flag to indicate how to expect provisioning to be initiated? Yes, flag indicating provisioning method is required agreed Does a reservation request require a pass/fail response from the Provider NSA? Response sent once reservation process completed. agreed Notification of provisioning? Notification of provisioning completion is required. agreed ------------------------------------------------------------------------------------------------------------------ Guy Roberts, Ph.D Network Engineering & Planning DANTE - www.dante.net<http://www.dante.net/> Tel: +44 (0)1223 371 316 City House, 126-130 Hills Road Cambridge, CB2 1PQ, UK ------------------------------------------------------------------------------------------------------------------
