August 2011: Zhenkai Zhu attended SIGCOMM and presented his work "ACT: Audio Conference Tool Over Named Data Networks" at SIGCOMM ICN Workshop.

May 2011: Lucas Wang, a graduate student in IRL, made a public release of EyeP, an IPv4 address allocation and usage visualization tool.

May 2011: The NDN project held a retreat at PARC May 23-24; we also attended the NSF FIA program PI meeting May 25-26. Here is the NDN team's presentation at the PI meeting.

1/1/2011: 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.

• TR030046: An Analysis of BGP Routing Table Evolution

December 2009: 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

September 2009: two of our recent papers may look interesting to people:

Inter-Administrative Challenges in Managing DNSKEYs
Eric Osterweil, Lixia Zhang
IEEE Security and Privacy: Securing the Domain Name System 7(5), September 2009.

Supporting Mobility in the Global Internet
Lixia Zhang, Ryuji Wakikawa, Zhenkai Zhu
ACM MOBICOM MICNET Workshop, September 2009.

• Evolution towards Global Routing Scalability
• Understanding Mapping.

• Managing Trusted Keys in Internet-Scale Systems, July 2009.
• Understanding the Challenges in Securing Internet Routing, July 2009.

March 2009: IETF74 was held in San Francisco. Our project team gave a few talks at the Routing Research Group meeting:

• "Scaling FIBs with Virtual Aggregation: How Much Stretch? How Much FIB Savings?" by Dan Jen.
• "Evolution Towards Global Routing Scalability" by Varun Khare
• "Terminology Discussion" led by Lixia

Janurary 2009: 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.

November 2008: 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".

October 2008: Several things to report this month.

• My paper "A Retrospective View of Network Address Translation" appeared in September/October issue of IEEE Network. This is one of my own "look-back" thought exercise. I welcome your comments!

• Our paper "Cyclops: An AS-level Connectivity Observatory" appeared in October issue of CCR. Ricardo gave a talk on Cyclops at NANOG-43 back in June; here is his presentation slides.

• Eric Osterweil attended IMC 2008 to present our paper on "Quantifying the Operational Status of the DNSSEC Deployment".

• Dan Jen attended HotNets 2008 to present our paper "Towards A Future Internet Architecture: Arguments for Separating Edges from Transit Core".

• A discussion with colleagues on IP mobility reminded me a talk I gave at Dutch Telecom Lab a couple years back, "What Are the Fundamental Challenges in supporting Mobile Routing? -- from an Internet person's view". This was right after I served on the INFOCOM 2006 panel "Design Principles for Enhanced Mobile Networks and Services" (hence the reference to that panel; PHTYMY=potentially harmful to your mental health :)

August 2008: 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 :-)

July 2008: 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).

June 2008: 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.

June 2008: 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)

December 2007: 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".

October 2007: I wrote an article for IETF Journal on "A Retrospective View of NAT".

June 2007: 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.

June 2007: BGP-Origins goes live and is eager for community participation and feedback.

March 2007: 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).

February 2007: I was appointed to co-chair the IRTF Routing Research Group with Tony Li of cisco.

February 2007: 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.

January 2007: IAB held a workshop on "Unwanted Internet Traffic" during March 2006. Here is the rworkshop report. We welcome your comments!

September 2006:
