Yes, you have read the title right. :D Hopefully, my first big conference is going to be CoNEXT’08 instead of IM’09, where I will be presenting a paper. This has come as a pleasant surprise !!! While I tried to make my case to the award committee as strongly as possible, the probability of really winning one is always very low due to the presence of a lot of applicants in such large conferences.
I would like to thank the award committee to give me the opportunity and the sponsors of the conference (Silver supporter Microsoft Research, Bronze supporters CISCO, Thomson, Nokia, CONTENT NoE and Patron IBM Corp.) for making it possible.
Aside from the conference, I am also excited about my first trip to Europe. I will try to cover some more cities apart from Madrid, since a schengen visa allows free movement between a whole bunch of countries.

Our paper “iMark: An Identity Management Framework for Network Virtualization Environment” has been accepted at IM’2009. Hopefully, I will be presenting my first paper at a major conference in New York next June :-D . The abstract of the paper is given below:
In recent years, network virtualization has been propounded as an open and flexible future internetworking paradigm that allows multiple virtual networks (VNs) to coexist on a shared physical substrate. Each VN in a network virtualization environment (NVE) is free to implement its own naming, addressing, routing, and transport mechanisms. While such flexibility allows fast and easy deployment of diversified applications and services, ensuring end-to-end communication and universal connectivity poses a daunting challenge.
This paper advocates that effective and efficient management of heterogeneous identifier spaces is the key to solving the problem of end-to-end connectivity in an NVE. We propose iMark, an identity management framework based on a global identity space, which enables end hosts to communicate with each other within and outside of their own networks through a set of controllers, adapters, and well-placed mappings without sacrificing the autonomy of the concerned VNs. We describe the procedures that manipulate these mappings between different identifier spaces and provide performance evaluation of the proposed framework.
If you are interested, head to my publications page to get the full paper.
The acceptance rate of IM’2009 is approximately 32%.

Update: This technical report has been superseded by an article that is to appear in the Computer Networks journal sometime in 2010 [LINK].
Finally, our survey on network virtualization is available as a technical report. If the abstract seems interesting (given below), you can download the report from here.
Due to the existence of multiple stakeholders with conflicting goals and policies, alterations to the existing Internet are now limited to simple incremental updates; deployment of any new, radically different technology is next to impossible. To fend off this ossification once and for all, network virtualization has been propounded as a diversifying attribute of the future inter-networking paradigm. By allowing multiple heterogeneous network architectures to cohabit on a shared physical substrate, network virtualization provides flexibility, promotes diversity, and promises security and increased manageability. In this paper, we present a network virtualization model with a set of quintessential design goals, survey the past and the state-of-the-art of network virtualization, and discuss the future challenges that must be addressed to realize a viable network virtualization model.
Since it is quite long (29 pages), here goes a brief summary. This article
- puts network virtualization into a historical perspective,
- presents a model network virtualization environment,
- surveys existing projects that are directly or indirectly related to network virtualization,
- summarizes key directions for future exploration.
We have tried our best it to make it informative and useful for the network virtualization research community. But any comment or critique from you will enrich it for sure. Don’t hesitate to grill or greet me. :-D
You should also check out my two presentations based on this survey: “An Introduction to Network Virtualization” and “Network Virtualization: Present and Future”.
On personal level, I have one chapter for my Master’s thesis. w00t !!!
