IETF in Maastricht
|
Before and during the IETF in Maastricht, July 25-30 2010 a new slew of I-Ds happened, from the quills of Hipercom@LIX:
NHDP was updated after AD review, and IESG evaluation started - hopefully, this is the second-to-last document in the core OLSRv2 protocol suite.
The OLSRv2 mib document also was updated as was the NHDP mib document and the the PacketBB-SEC document -- the latter of which now is a working group document (yay!).
A new I-D, YAAP was published, detailing one current ad hoc address autoconfiguration protocol.
In the Wireless Sensor Networking area, two new documents were published: a p2p (sensor-to-sensor) extension to RPL and a performance study hereof. |

|
Ulrich will present the paper he's written with Ian Taylor, entitled "Development Framework for Supporting Java NS2 Routing Protocols" -- for those in the know, this is all about the AgentJ-for-routing-protocols work: take a routing protocol implementation, written in Java, add AgentJ (without modifying code) and it "just works" with NS2 - neat!

Yep, that's right: the next IETF is approaching, and this time in the city of love: San Francisco.
Three new I-Ds have seen the day of light, from the pens of Hipercom@LIX: updates to NHDP and OLSRv2, of course, and a brand new document on MANET Router Configuration Recommendations.
So, Hipercom@LIX will let our beards grow, have found our sandals and the tie-dye shirts, packed our laptops in our patchwork bags and....ohh...we'll try to rent an old VW bus to get around.

New Std. Track RFC Published - PacketBB (RFC5444)

It was a while coming, but finally it's here: the "Generalized MANET Packet/Message Format" has been published as RFC5444 with status "Proposed Standard". This document is authored by T.Clausen (Hipercom@LIX), C. Dearlove (BAE Systems), J. Dean (NRL) and C.Adjih (Hipercom@INRIA)
Pretty much all MANET wg documents (incl., TimeTLV, NHDP and OLSRv2) have normative references to this document -- and so this publication means that the MANET wg is able to progress also these other documents. YAY! |

Interoperability tools for packetbb
|
For those of you who have implemented packetbb, or who plan to do so, Ulrich has put some online interoperability tools here: OLSRv2 Protocol Suite Interop Tools
These tools have been used at the 4th OLSR Interop Workshop, and since then updated to the new version of the packetbb draft.
Further interoperability tests for NHDP and OLSRv2 will follow soon. |

A slew of new I-Ds
|
Alright, so before and during IETF'73, a slew of new I-Ds happened.
Besides updates, including TimeTLV, PacketBB and MPR-OSPF, a couple of new I-Ds have seen the light of day.
First, together with Rob Cole, a MIB document for OLSRv2 has been published OLSRv2-MIB.
A piece of commissioned work on a view on the MANET Link Type also happened -- although what will happen to this document is unknown.
And, finally, with Yannick Lacharite from CRC and Pascale Minet from Hipercom@Rocq, a scalability extension to OLSRv2 saw the light of day: Hierarchical OLSR.
At least a couple of new I-Ds are in the works, so stay tuned.... |

4th OLSR Interop/Workshop a success
|
The 4th OLSR Interop/Workshop is over, and man was that fun. We were about 24 people in the beautiful city of Ottawa, where CRC and Yannick Lacharite were hosting this event in the best way possible.
4 complete OLSRv2 / NHDP / PACKETBB implementations were present, and an additional 4 PACKETBB implementations were represented -- all individual code-bases, of course.
Funkfeuer.at, NRL, TNO.nl, Hitachi, Niigata University and our own Ulrich with the jOLSRv2 code, all brought code, and we had a blast at testing.
As a teaser, the next Interop/Workshop in 2009 will be held in Vienna in september. Stay tuned for an announcement with more details, but this event promises to expose us to probably the biggest MANET in the world..... |

Readying for IETF'72 - Updated I-Ds.
|
Only about 2 weeks left before the next IETF in Dublin, and we're racing to ready our documents in time. A brief update on where we are.....
draft-ietf-ospf-manet-mpr has gotten a major overhaul for this IETF, aiming to get ready for a WGLC. This document is aiming for Exp..
draft-ietf-manet-packetbb and draft-ietf-manet-timetlv have both been revised as per IESG review requests. This document is aiming for Std. Track.
draft-ietf-manet-nhdp and draft-ietf-manet-olsrv2 have both been updated to correspond with the changes to draft-ietf-manet-packetbb and draft-ietf-manet-timetlv, with, draft-ietf-manet-nhdp having been updated with some motivational text and a couple of other nits. Both of these documents are aiming for Std. Track.
draft-dearlove-olsrv2-metrics has been reissued, updating our reflections on how to integrate additive link metrics into OLSRv2.

jOLSRv2 extension for NS2
|
After having announced a Java implementation of OLSRv2, named jOLSRv2, we have completed an extension of jOLSRv2, to allow it to run within the NS2 simulator.
The extension bases on the AgentJ-library by the Naval Research Laboratory (NRL - USA). This library uses Java Native Interface (JNI) to access Java programs from C++ and vice versa. As the library uses bytecode rewriting, no change of the jOLSRv2 source code had to be made, it runs "as is" on NS-2.
For simulations under realistic conditions, we have modified AgentJ in several ways, for example to use IPv6 addresses instead of the NS2 addresses.
The source code (together with the jOLSRv2 source code) will be released soon on this page, so have a look on our news page regularly - or better yet: subscribe to our RSS-feed.

The IETF activities of Hipercom@LIX got mention in today's daily updates at defensesystems.com, where the I-Ds on the "neighborhood discovery protocol" (NHDP), and packet format (packetbb) were mentioned, as was our recent RFC5148.
Finally, defensesystems.com gave mention to our recently announced jOLSRv2 implementation thus:
"....Researchers at the Working Group meeting also unveiled some MANET test cases and prototype implementations
.......
described implementations of MANET's Optimized Link State Routing, a protocol for building link tables for ad-hoc networks, including those built at France's Laboratoire d'Informatique de l'Ecole Polytechnique....." |

RFC5148 "Jitter Considerations in Mobile Ad Hoc Networks (MANETs)" has been published. Authored by T. Clausen (Hipercom@LIX), C. Dearlove (BAE Systems) and B. Adamson (NRL), this marks the first document to be "set in stone" through publication as an RFC in the current generation of IETF MANET specifications.
Others are bound to follow, and we'll try to make it asap.... |

jOLSRv2
|
We are happy to announce a new implementation of OLSRv2 called "jOLSRv2". One of our PhD students, Ulrich Herberg, implemented it in Java according to the newest versions of the I-Ds currently available:
http://tools.ietf.org/html/draft-ietf-manet-olsrv2
http://tools.ietf.org/html/draft-ietf-manet-nhdp
http://tools.ietf.org/html/draft-ietf-manet-packetbb
The java implementation allows easy deployment on all kind of platforms without recompilation. The software is split up into a command-line server and a completely independent Swing client which can connect to the server using Java RMI. Acoording to the modular structure of the drafts, the NHDP and packetbb part of the implementation can be used independently as stand-alone solutions. In addition, the completely documented and commented code allows to add extensions easily. We will announce some interesting extensions and a downloadable version of this software to play with on this website soon. |

New WG I-D accepted: draft-ietf-ospf-manet-mpr-00.txt
|
After existing as an individual submission for a while, the Hipercom proposal for a MANET extension to OSPF has been accepted as an OSPF working group document.
This entails that the OSPF WG has accepted to see this document through to publication as experimental RFC - obviously, we hope this process will succeed sooner rather than later.
This I-D is authored by Emmanuel Baccelli (Hipercom@LIX), Philippe Jacquet and Dang Nguyen (Hipercom@Rocquencourt) and Thomas Heide Clausen (Hipercom@LIX) |

Vancouver is cold, wet and windy -- fortunately, an IETF leaves little time to go outdoors....
|
So the 70th IETF in Vancouver is over, and as usual a lot of things have elapsed (despite the weather doing its best to keep the IETFers from arriving). Here's a brief update of the main news items:
* draft-ietf-autoconf-manetarch has been submitted in an updated version, subsequent reviews from Jari Arkko and Dave Thaler
* draft-ietf-manet-nhdp has been updated, is thought to be "done" and is now moving forward -- with SECDIR review being the next step
* draft-ietf-manet-olsrv2 has also been updated, and is now also considered "done". Pending a final review, a new version will apear.
Some "new things" were promised, and were launched too. These will be announced shortly, so stay tuned (i.e. subscribe to the RSS feed....) for more shortly. |
|
|
|
And so, another document from Hipercom@LIX approved as RFC....
|
The document recently known as draft-ietf-manet-jitter-04 has just now been approved by the IESG.
IESG approval means, that the document has passed all technical reviews necessary, and that the next step is the RFC Editor, who'll ensure that formatting and other such formal issues are a-ok, attribute an RFC number and a new RFC will be born....
Obviously, we're very excited about this news.
This I-D (well, soon-to-be-RFC) is written by T.Clausen (Hipercom@LIX), C.Dearlove (BAE Systems, UK) and B.Adamson (NRL, USA). |

WGLC for TimeTLV
|
A WGLC (Working Group Last Call) has been issued for the I-D draft-ietf-manet-timetlv, developed jointly by Christoper Dearlove (BAE Systems) and Thomas Clausen (Hipercom@LIX). The WGLC of this I-D closes on Nov. 30, i.e. before the next IETF. The content of this I-D should be rather straight-forward, so we are hoping for smooth progress during and after WGLC. This I-D is scheduled for publication as a Proposed Standard RFC.

OLSR Implementation Survey
|
Philippe Jacquet has done some counting, and come up with a nice map of where OLSR - the predominant MANET routing protocol, developed by Hipercom - has been developed and deployed.
This brief survey includes only PUBLIC OLSR and OLSRv2 implementations, i.e. those that one could otherwise find via google....
After having borrowed fingers and toes from the rest of Hipercom@LIX, the result was that there are 6 publicly known OLSRv2 implementations, and 35 publicly known OLSR (RFC3626) implementation.
Of course, such numbers are rather boring -- but take a look at the image above (or click on the URL for a larger version). Can we safely say that OLSR has gone World Wide? :) |
