[Sorry for duplicate notifications] FYI only. OSCARS NSI Bridge is r117 compatible now and is available for download. Please talk with Vangelis if you need more information or details. Thanks Inder ---------- Forwarded message ---------- From: Vangelis Chaniotakis <haniotak(a)gmail.com> Date: Tue, Mar 11, 2014 at 1:23 PM Subject: OSCARS: new NSI bridge RPM released To: "noc(a)manlan.iu.edu" <noc(a)manlan.iu.edu>, "noc(a)net.internet2.edu Operations Center" <noc(a)net.internet2.edu> Cc: Chin Guok <chin(a)es.net>, Dale Finkelson <dmf(a)internet2.edu> All, The new NSI bridge RPM has been released with support for NSI 2.0 r117 (as opposed to the previous protocol version, r99). The main change in the protocol involves the STP format. The upgrade procedure is to run: yum update oscars-nsibridge There is also a slight configuration change. The affected file is: /etc/oscars/NsiBridgeService/conf/nsa.json the "networkId" will need to change from its old format to a simpler new format: previous format example: "urn:ogf:network:es.net" new format: "es.net", Do let me know if you encounter any issues. Thank you!

NSI implementation call cancelled
by John MacAuley 19 Mar '14

19 Mar '14

Peoples, I have decided to cancel this Wednesday's NSI implementation call. I do not believe the call would be productive and we should all be preparing for the face-to-face in Atlanta in less than two weeks. We have had some good discussions since the meetings in Oxford, but I am not completely happy with the overall progress. To quote Scrum terminology: we have very few pigs and a whole lot of chickens. We need more pigs. I know we are a very opinionated group with a lot of good feedback; however, we need to make progress on key issues before production implementations can be deployed. For this reason we need people with ideas and constructive feedback on the key topics to get it down in contributions with clearly defined solutions that meet the requirements and fit into the NSI Service Framework. We do not want contributions that redefine the existing NSI architecture and throw out 5 years worth of requirements, so please keep it focused and on track. Here are the items that need to be addressed in the Atlanta meetings. It is long and I know we do not have a lot of time. I will discuss with Guy to determine in which time slots the topics are best discussed. · NSI identifier format (STP, et al.) · NSA Discovery Document (John to present overview and next steps) · NSI Discovery Service (John to present overview of his solution, ?) · NSI Topology Service (if distinct from Discovery Service) · Verification of topology information (Chin) · User security (Hans to present SURFnet solution) · Ethernet extensions (John and Freek) · NML Adaptation (John and Freek) · NSI-EXT document (John) Are there additional topics to discuss? If you are planning on contributing a presentation or formal document please let me know so we can allocate you a time slot. This is your chance to shed those feathers and be a resplendent pig. John

Stepping down as NSI co-chair
by Inder Monga 17 Mar '14

17 Mar '14

Dear All, Since the Barcelona meeting at OGF where the concept of NSI was formalized and the name chosen, it has been a long and fruitful journey producing concepts and abstractions, encapsulating them in a protocol that we believe will stand the test of time. As NSI 2.0 reaches fruition (Public comments end April 2014), I am stepping down as the NSI co-chair. The reason is my work commitments are dwarfing the amount of time I have available to continue being an effective NSI co-chair. In the past few years, I really appreciate the teamwork of my co-chairs - Guy and Kudoh-san, who have worked tirelessly and in an unbiased manner with me to promote the protocol, gather community requirements, and smooth ruffled ego's - so common in a standards process - towards a productive, collaborative development of a protocol driven by real requirements. In addition, I appreciate all the members of the NSI community that have attended calls every week and contributed so much of their technical knowledge and understanding. These interactions are priceless and I will be stepping down with great memories. Thanks for all your support!!! I will continue to be involved with the NSI community - so this is not a farewell, but will only take a less active role in driving its evolution. The interaction and welcome that GENI gave to the NSI group today is heart-warming, and I believe we have a lot to learn from each other. Guy will follow-up in email with the nomination process for a replacement co-chair. Live long and prosper, Inder Inder Monga | imonga(a)es.net Chief Technologist and Area Lead | http://www.es.net/inder Energy Sciences Network (ESnet) <http://www.es.net>

Input for GLIF meeting
by Freek Dijkstra 17 Mar '14

17 Mar '14

Hi all, Unfortunately, I will not be able to attend the NSI and GLIF meeting coming week. Here is our (SURFsara) stand with regards to the current service discovery and topology distribution proposals. Summarizing John's proposal: - recursively flood discovery services info to neighbours - recursively flood topology files to neighbours We think that this is a major improvement over the current bootstrap document on Github used by AutoGOLE. We don't think it's perfect. Our main critique is: - there is no aggregation of topology - it requires full topology knowledge Our minor critique is: - scalability: long distribution path. Our preference would be that topology docs would be publicly available at each domain. (though we are aware that some organizations are reluctant to publish this information). - security: poor PKI. (none to speak of?) - flexibility: no distinction between identifiers and addresses We like to see a better infrastructure in the future, but will not pursue that for now (at least not before fall 2014). The reason is that we think it is better to gain more experience with (1) PKI and security aspects of non-central topology distribution; (2) experience how NSI interacts with other technologies, like OpenFlow (3) understanding the trade-offs of hierarchical addresses, and the distinction between identifiers and addresses. Concluding, we support John's proposal for discovery services and topology distribution as a solution that is good with the current scale and requirements of the NSI community, and hope to work with you on a better solution for the future. I wish you a fruitful meeting!
