CFP: International Conference on Networked Systems 2017

International Conference on Networked Systems 2017

March 13-17, 2017 – Göttingen, Germany

CALL FOR PAPERS [PDF]

The Conference on Networked Systems (NetSys 2017) provides an international forum for engineers and
scientists in academia, industry, and government to discuss recent innovations in the realm of
networked systems – including aspects of networking, distributed systems, communications,
middleware, and applications. NetSys conference proceedings will be published in IEEE Xplore®.

NetSys is a biennial event that originates from the key scientific conference on networked systems in
German-speaking countries KiVS (Kommunikation in Verteilten Systemen) – which was initiated 37
years ago and has international orientation since 2013. NetSys is organized by the special interest
group “Communication and Distributed Systems” (KUVS), which is anchored both in the German
Computer Science society (Gesellschaft für Informatik (GI)) and in the Information Technology
society (Informationstechnische Gesellschaft im VDE (ITG)).

NetSys solicits submission of high-quality, original scientific papers presenting novel research on
the wide range of networked systems, including but not limited to:

Network architectures and protocols
Smart grid
Transport- and application-layer protocols
Information-centric networking, content distribution and retrieval
Peer-to-peer and overlay networks
SoA, web services, and mobile services
Software-defined networking andnetwork/functionality virtualization
Consistency, reliability, availability, and programming support
Mobile, ad-hoc, opportunistic, vehicular and sensor networks

Re: [tcpm] Question on RFC6298, Managing the RTO Timer and additional lost pakets in Recovery state

Hi Yuchung, thanks for the help

I seem to have gotten the RFC6937 (PRR) behavior in place.  Currently I don't see much gain with PRR, one
possible reasons is that AQMs in LTE are typically a bit on the "bufferbloated" side as too low drop
thresholds easily causes links be underutilized. The effect of this is that when  a loss event occurs,
there will be enough data in the RLC queue to transmit even though the congestion window is cut in half
immediately. There could still be benefits with PRR in terms of less RTO.

I believe then that I am getting closer to a good Linux TCP model in our simulator. 
I still have one particular behavior that I don't really understand, I am almost 100% sure that the error is
on my side

Thanks for the ref to the sigcomm paper, I seem to have missed it.

Question on RFC6298, Managing the RTO Timer and additional lost pakets in Recovery state

Hi

I am trying to understand the Linux TCP stack and how it rearms the RTO timer, in the process I  read section 5 in RFC6298.
It says quote "(5.3) When an ACK is received that acknowledges new data, restart the retransmission timer
so that it will expire after RTO seconds (for the current value of RTO)."
What is the definition of new data ?. The strict interpretation is when SND.UNA advances, but it can also be
that the highest SACKed sequence number increases. The former case it is more likely that RTO happens.

The second question is Linux related. Given that a lost packet puts the stack in Recovery state, the
congestion window reduces one step as an effect on this. What happens if additional packets are lost when
in Recovery state. I guess the congestion window should decrease more or ?.

I am currently porting the Linux TCP stack to fit our Java based system simulator, most things seem to be
working but the above leaves me wondering.

IEEE Internet Computing special issue


Folks-

In case anyone is has some cool measurement work that needs a home,
I wanted to mention that papers will soon be due for a special issue
of IEEE Internet Computing on the topic of 'Measuring the Internet'.
Papers are due Oct 30.  All the info is at the following URL:

DOE Network 2025 Challenges - Call for Position Papers


                     DOE Network 2025 Challenges

                       Call for Position Papers

The US Department of Energy Office of Science - Advanced Scientific
Computing Research (DOE/SC - ASCR) program office is pleased to
announce the Network 2025 Challenges workshop. This workshop will be
held Feb 1-2, 2016 in the Washington, DC area. DOE/SC operates a large
collection of unique experimental and computing facilities, which
generate and consume petabytes of data on a monthly basis
(http://science.energy.gov/user-facilities/user-facilities-at-a-glance/). The
goal of this workshop is to engage and coordinate the computer
communications research community with the DOE/SC science communities
to articulate the network and transport layer research challenges for
the next decade.

The workshop is intended to foster discussions that will generate a
roadmap which is expected to guide a multi-program, decade-long
network and transport layer research effort as part of a larger,
comprehensive network research program to support DOE's science
missions. Other workshops will address other layers of the network
stack. Of particular interest are medium-term (5-year) challenges,
long-term (10-year) challenges, and non-traditional challenges ("what
if...") that present unique opportunities for DOE's scientific
networking needs.

Attendance at this workshop will be limited and informed by position
papers submitted by interested researchers. These papers will be
circulated to initiate pre-meeting discussions. Invited participants

PAM 2016 - Call for Papers


Passive and Active Measurement Conference 2016 (PAM 2016)
31 March - 1 April 2016
Heraklion, Crete, Greece
http://www.ics.forth.gr/pam2016/ <http://www.ics.forth.gr/pam2016/>

Call for Papers

PAM seeks to bring together both the network research and operations communities to consider network
measurement and analysis techniques, particularly those in the earlier stages of research.

PAM has in the past focused on research and practical applications of network measurement at Layer-3.
However, over the last years PAM broadened its scope to encompass measurements of networked
applications, content distribution networks, online social networks, overlay networks, and more.
Measurement technology is needed at all layers of the stack: for power profiling of hardware components;
at the MAC/network/transport layers; as well as up the stack for application profiling and even to
collect user feedback. Measurement technologies are being designed for the digital home, residential
access networks, wireless and mobile access, enterprise, ISP and data center networks.

Although PAM traditionally attracts work that is at an early stage, works that are a reappraisal or
independent validation of previous results, or which enhance the reproducibility of network
measurement research, for instance by publishing new datasets on an existing topic, are explicitly
included in PAM's ambit.

Original papers are invited, but not limited to, the following topics:
Tools and infrastructure:
Passive and active measurement tools: techniques, design and experience
Management and operation of measurement infrastructures
Management and visualization of measurement data
Measurements across the stack:
