NDN Community Meeting (NDNComm) is an annual event that brings together a community of researchers from academia, industry, and government, as well as users and other parties interested in the development of Named Data Networking (NDN) technology. NIST hosted 2019 NDNcomm September 5-6, 2019 in DC. One can find the agenda and the meeting video recording on the NIST website.
Long overdue, we finally put together An Overview of Security Support in Named Data Networking, appeared in November 2018 issue of IEEE Communications.
One question that comes up again and again about how NDN could ever get rolled out, given the existing investment into TCP/IP infrastructure: this reminded me a
;Login interview KC and I did early 2016. Quoted below is the ending paragraph of that interview article, if we can learn something from history:
Our ACM ICN 2018 paper “KITE: Producer Mobility Support in Named Data Networking” represents a promising solution to NDN protocol mobility problem.

We released a ns-3 based NDN simulator in June. Please try it out and let us know your comments/bug reports/new feature suggestions! Interested users are welcome to joint ndnSIM mailing list.
If March was a busy month, then June has been twice as busy. I hit the ground running right after my last lecture of spring quarter. I attended the annual Hong Kong Research Grant Review Panel and was invited to half dozen universities and institutions around China to talk about NDN. More and more people become interested and excited about the named data networking direction!
March was a busy month. As soon as winter quarter teaching ended, Jim, Van and myself attended AsiaFI NDN Hands-on Workshop held at Seoul National University March 19-21; I went to Paris for IETF83 afterwards; then three of us met again at INFOCOM NOMEN Workshop on March 30th.

Here is what I put out on 1/1/2010:
1/1/2010: The new decade seems to need a new acronym--the thing we used to call "cellphone" is no longer a phone; it has become a general-purpose computer and making calls is merely one of its many app's (e.g. look at your iPhone). At the same time a number of new types of hand-held "devices" (for lack of a better word) have shown up, e.g. Amazon's Kindle, iPod, or this forever coming Apple tablet.
Here is a suggestion for a new acronym for them all: HHDs, for Hand-Held Devices.
I believe people would generally agree with me that the last year is a year marked with leaps and bounces in technology advances and usages of hand-held devices, even though I do not know whether people liked the acronym HHDs :-)
October 2010: We have set up a website for our new project Named Data Networking.
One of our ongoing projects is to measure the prevalence and persistency of the usage of unallocated IP address blocks. This got me to reread 2 technical reports from 2003 that never got published, they still look rather relevant today:
Our joint proposal with PARC and eight other universities, "Named Data Networking (NDN)" which is based on Van Jacobson's vision of CCN, has been funded under NSF's Future Internet Architectures (FIA) program (see NSF's press release).
Our paper on "Investigating occurrence of duplicate updates in BGP announcements" received PAM 2010 Best Paper Award.
Today is the first day at IETF77. Accidentally, or not accidentally, several people talked to me about how to secure today's global routing or DNS systems, given that not only solution developments take time but the adoption is also uncertain and slow. My answer: adding a monitoring system can be an effective and readily deployable first step towards securing your system. See our Cyclops global routing monitoring system, and SecSpider DNSSEC monitoring system.

As the end of 2009 approaches, we received a nice email (a nice Chritmas gift:) from the editors of Computer Networks commenting our paper submitted to a special issue on Interdisciplinary Paradigms for Networking:
"... In stark contrast, your paper is simply beautiful. It is well organized, clearly presented in fine English with obvious effort made to effectively communicate. I thoroughly enjoyed reading it and am sure that our readers will, too. I can imagine that it will inspire researchers to attack networking problem along the lines you indicate. May it be cited at the high rate that it deserves!
Sorry for so many words but I do want to thank you for a lovely paper!
Here is that paper (and Michael deverses the major credit!):A Taxonomy of Biologically Inspired Research in Computer Networking
Michael Meisel, Vasilis Pappas, Lixia Zhang
two of our recent papers may look interesting to people:
Inter-Administrative Challenges in Managing DNSKEYs
Eric Osterweil, Lixia Zhang

Supporting Mobility in the Global Internet
Lixia Zhang, Ryuji Wakikawa, Zhenkai Zhu
ACM MOBICOM MICNET Workshop, September 2009.
I attended IETF75 held in Stockholm 7/26-31/09.
Our project team gave 2 talks at the Routing Research Group meeting on July 31.
In preparing for IETF75 we made several Internet draft submissions.
We presented 2 papers at The Workshop on Trust and Security in the Future Internet (FIST '09):
IETF74 was held in San Francisco. Our project team gave a few talks at the Routing Research Group meeting:
After couple of years of hard work on design, development, collecting feedback from operators and revising again, Cyclops is finally getting into a good shape! Ricardo is still busy with further tunings but an annoucement to NANOG will probably show up soon.
I am teaching 2 courses during winter 2009, CS118 (Introduction to Networking) and CS217A (Internet Architecture & Protocols). This will keep me extremely busy for next 3 months.
It is commonly recognized that the Internet AS-level topology inferred from publically available BGP data is incomplete, however there has been no quantitative estimate on exactly how incomplete the inferred topology might be. We addressed this question in a recent technical report, "Quantifying the Completeness of the Observed Internet AS-level Structure".
Several things to report this month.
I happened to cross my very first published paper "Why TCP Timers Don't Work Well" (SIGCOMM 1986 Best Student Paper Award), and was a bit amazed by how well it reads 22 years later :-)
My paper "A Retrospective View of NAT" will appear in IEEE Network Special Issue on Middleboxes, September 2008 (Time flies! 9 years have passed since I coined the word middlebox back in 1999).
Summer internship seems the fashion this summer: Jonathan Park went to Intel Labs; Ricardo Oliveira went to Juniper; and Eric Osterweil went to PARC to work on a project led by Van Jacobson.
Ricardo had a busy month, he attended SIGMETRICS 2008 to present our paper on "In Search of the elusive Ground Truth: The Internet's AS-level Connectivity Structure", as well as NANOG 43 and presented "Cyclops: An Internet AS-level Observatory"(slides)
Dan Jen and Michael Meisel gave a presentation at the IRTF Routing Research Group meeting held in Vancouver, Canada on "APT: A Practical Transit Mapping Service".
I wrote an article for IETF Journal on "A Retrospective View of NAT".
I missed NANOG-40, but 3 IRLers made it, each gave a talk: Mohit chaired the BGP Tools BoF and presented Link-Rank, Eric presented BGP-Origins, and Ricardo presented a lightning talk on Cyclops.
BGP-Origins goes live and is eager for community participation and feedback.
Recently there have been lots discussions on "separating locators from identifiers". However different communities using this phrase to mean different things. To clarify the terminology, I gave a short talk at recent HIP Research Group meeting(slides).
I was appointed to co-chair the IRTF Routing Research Group with Tony Li of cisco.
The Internet routing scalability has been a focus of recent discussions in the IETF community (see mailing lists architecture-discuss@ietf.org, ram@iab.org). IAB held a workshop on Routing and Addressing in October 2006. Here is the latest draft of the workshop report.
IAB held a workshop on "Unwanted Internet Traffic" during March 2006. Here is the rworkshop report. We welcome your comments!
I wrote a short article for IETF Journal on multihoming impact on routing scalability and GSE analysis.
The Internet Engineering Task Force (IETF) celebrated its 20th Anniversary. As one of the 21 attendees for the first IETF meeting held in January 1986, I was interviewed by the IETF Journal.
Here is my interview.
