Fwd: [Fwd: Re: Architecture strawman]
by John Vollbrecht 10 Apr '09

10 Apr '09

Attached is revise strawman doc. If Joe and Chin and others can edit it further and send it back to me that would be good. I would like to discuss it further on Wed at our call. I suggest that everyone look at it and if they have edits or suggestions send them to me or to the list. I will try to update the doc as soon as possible. I have been out a lot for the last week, my father in law died on wed after a couple weeks of fairly intense events and issues that I have been mostly supporting my wife with. The interment will be next Thursday, so there will be a couple more days then. That is why I haven't been more active in dealing with the edits. I look forward to the discussion next wed.

by Guy Roberts 06 Apr '09

06 Apr '09

Hello All, OGF26 is now only 6 weeks away, in preparation I have booked two 90 minutes sessions for OGF26. You will recall that the target for this meeting is to prepare a draft version of the Architecture deliverable. Please let me know if you wish to add any specific items to the agenda, or have a presentation that you would like to make. Regards, Guy -- _____________________________________________________________________ ** Guy Roberts, PhD Network Engineering & Planning * * Tel: +44 (0)1223 371300 * * City House Direct: +44 (0)1223 371316 * 126-130 Hills Road Fax: +44 (0)1223 371371 * Cambridge * CB2 1PQ E-mail: guy.roberts(a)dante.org.uk D A N T E United Kingdom WWW: http://www.dante.net _____________________________________________________________________

additional call notes
by John Vollbrecht 01 Apr '09

01 Apr '09

A couple additional notes from the call this morning We had a lot of discussion about parameters and the difference between abstract and technology specific parameters. We had a list of parameters in the issues doc, and Guy will edit these into the strawman doc. Discussion about the parameters - abstract parameters seem to imply a range - e.g. a 100mb depends on what exactly what technology and network are used, whereas a 10GE interface is specific about what is provided at least at the interface - Tomohiro made the distinction between quality parameters for the connection as a whole and parameters at the edge point. Edge point parameters are things like VLAN or slot numbers, quality parameters are things like jitter or drops. Edge parameters are required, some quality parameters are optional (some may be required). --- We talked about whether Waves and fiber bundles were alternative connection topologies. We had discussion about whether waves were appropriate as raw input or if waves always started as bits. If waves start as bits, then it seems to me there is an adaptation to carry them on waves, but the underlying "type" of connection is bits. Joe pointed out that waves were being switched in labs and that standards should handle the future where possible. Also fiber bundles are less problematic and can be switched, and their characteristics are not bits. So a question I have is whether NSI should be interested in data (bits) connections or also in generic connections like waves or fiber bundles. This is to be determined - I would be interested in comments. There is also a need to describe L3 and perhaps L4 connections if we want to do that. It might be possible to say these are possible but concentrate on L2 for first pass of the document. --- A discussion about different services that are used by and perhaps provide by a NS included the suggestion by Chin (which seems right to me) that Topology sharing be described basically for inter NS but allow it to be used by others. I think the intent is that we should include this as needed to support inter NS capability and assume that will be sufficient for other users. --\ Please comment or add to any of these - John

call notes - Internet2 SMM meeting
by John Vollbrecht 01 Apr '09

01 Apr '09

We had a good call today. I edited the strawman doc based on comments as I understood them. I agreed to put details of NSI ad hoc meeting at Internet2 SMM. The meeting is from 4-6 pm Monday April 27 in Washington DC. The agenda depends on who will be able to attend. There is also an ad hoc meeting to discuss dynamic GOLE earlier Monday afternoon of people are interested. Some changes in the attached doc - to clarify distinction between connection oriented and IP net. - to section describing NS, to make clear that a NS is provided by Link, Network or set of Links and Nets - to Functional requirements intro section to descibe additional services that are part of NS - to Functional requirements sections to put some notes on what might be in different sections Guy, Joe, Tomohiro and others will edit doc. Tomohiro will add Reservation section. Guy will add parameter section. Joe will send and edit pass. I will try to get input from NML folks for the naming section We will have next call in 2 weeks - April 15. John

First cut at NSI arch strawman/call info
by John Vollbrecht 31 Mar '09

31 Mar '09

We will have a call next wed at 9 ET call info is Call: +1-734-615-7474 (PSTN CALL-OUT DOES NOT WORK) or +1-866-411-0013 (toll free US/Canada Only) Enter access code: 0155180 Attached is a first cut at a document that might be a strawman architecture doc for end of May. It has some initial sections and a set of proposed sections. I attempted to describe the architecture in some detail, and included a Glossary of terms (which might be better moved to a different location - any suggestions?). I would like to review the doc and especially the headings and glossary next Wed to see if we can come up with an agreed outline. If we agree then we need to have editors for each section. I propose the following from the group that has been participating - it is a starting place for discussion. Please suggest changes and also please comment on whether any seems unreasonable and/or would work for you. 1. Doc Overview [ Guy, Tomohiro, John] 2. NSI arc overview [ John, Tomohiro, Guy, Pascale, Chin, Joe, Jerry ] 3. Connections - Network and User View [ John, Joe,Tomohiro, Radek, Pascale, Aaron, Eduard] 4. NSI environments [ Radek, Joe, Guy, Joan, Jerry] 5. Reservations, resources and instantiation [Tomohiro, Chin, Evangelos, Andy Lake] 6. Negotiation [Jerry, Chin] 7. Naming [Jeroen, Aaron, Freek, John, Chin] 8. Policy, Authentication and Trust, Prioritzation, Job Control [tbd] 9. Interface description details [Radek, Andy, Joan, Chin, Evangelos, Fred] other?

Re: [Nsi-wg] Call for Participation: OFC/NFOEC Workshop on Grid vs Cloud/Utility Computing and Optical Networks
by Simeonidou, Dimitra 19 Mar '09

19 Mar '09

Dear Colleagues, This is invite you to attend the upcoming workshop at OFC/NFOEC (see http://www.ofcnfoec.org/conference_program/Workshops_and_Panels.aspx) Here's the latest info on the workshop. Feel free to dsitribute to your colleagues and hope to see you there. ------------- Workshop Title: Grid vs Cloud Computing and Why This Should Concern the Optical Networking Community Time and Place: Monday March 23, 2009, 8 to 11am, Room 6E at the San Diego Convention Center Organizers: Chunming Qiao¹, Dimitra Simeonidou², Bill St. Arnaud³, Peter Tomsu4; ¹SUNY at Buffalo, USA, ²Univ. of Essex, UK, ³Canarie Inc., Canada, 4Cisco Systems Ltd., USA. Descriprtion: Recently, there has been a lot of interests in Cloud, Grid and Utility computing and their influence in shaping the future network infrastructure. While Grid Computing is geared mainly towards scientific users and Grids, both Cloud and Utility computing are for enterprises. The common point for both approaches is their reliance on high speed optical networks to provide advanced and flexibly reconfigurable infrastructure. Optical network researchers are facing big challenges in delivering the necessary technologies for supporting Cloud, Grid and Utility computing services. Such technologies and services will change the Internet in much the same way as distributed and parallel computing has changed the computation and cyber-infrastructure today. The workshop will discuss various Cloud, Grid and Utility Computing approaches and will present the challenges (research and implementation) for our community. Schedule: Welcome/Introduction Clouds and Optical Networks, Bill St. Arnaud, CANARIE Inc., Canada Challenges in Enabling Cloud Computing over Optical Networks, Piero Castoldi, Barbara, Martini, Fabio Baroncelli, Scuola Superiore Sant'Anna Univ. Italy Challenges in Enabling Grid Computing over Optical Networks, Cees de Laat, Univ. of Amsterdam, Netherlands Virtualizing and scheduling network resource for emerging IT services: the CARRIOCAS approach, Pascale Vicat-Blanc Primet (INRIA) & Dominique Verchère (Alcatel Lucent BellLabs) Energy / cost beneifts of cloud computing, Rodney Tucker, U. Melbourne, Australia Opportunities in Optical Grid and Clouding Computing, Chunming Qiao, SUNY Buffalo, USA Panel discussion and Q&A
