[aims-announce] [Mycolleagues] Open postdoc position at Troyes University of Technology (France)

[Guillaume Doyen]

Open  Postdoc position  at Troyes  University of  Technology (Institut
Charles Delaunay – UMR CNRS 6281)

* Title:
Implementation of a NDN testbed based on virtual network functions for
long-term measurement campaigns

* Funding: 
- ANR  DOCTOR (DeplOyment  and  seCurisaTion of  new  functiOnalities 
in   virtualized    networking   enviRonments) - ANR-14-CE28-0001
- Champagne Ardenne Region Excellence program - A2101-03


* Context: 
According to  the Cisco Visual  Networking Index, the  global Internet
traffic  will still  increase over  next years,  mainly due  to mobile
devices while the  current network investments are  very limited. This
has led  to the  point where solutions  enabling network  operators to
invest, and  at the same  time deploy new impacting  technologies, are
crucial. The  virtualization of network  functions now brings  such an
opportunity and  NFV (Network Virtualization Function),  as defined by
the ETSI, is  the key technology that leverages this  concept.  With a
similar  objective   of  network   efficiency  and   operational  cost
reduction, Information-Centric Networking (ICN)  is a novel networking
paradigm,  which proposes  an  Internet data  plane  that shifts  from
host-based network mechanisms to content-based ones. However promising
the prospect  may seem,  network operators  are reluctant  to globally
deploy  such  a  novel  data plane  architecture,  for  the  following
reasons: (1) the  huge initial investment costs it  requires; and, (2)
the risk  involved in  introducing such  a technical  breakthrough and
migrating  from IP  to ICN  in a  single step.  Therefore, progressive
deployments  have  to be  considered,  in  terms of  topology  (access
networks,  core  networks, etc.)   or  services  (data, voice,  video,
etc.).

The  ANR DOCTOR  project  takes  part in  this  effort and  especially
advocates the use  of virtualized network equipment,  which could ease
the deployment  of novel  networking architectures, thus  enabling the
co-existence of IP and emerging  stacks (e.g. ICN) and the progressive
migration of traffic from one stack to the other. Novel services could
then be  deployed in the same  network equipment, each having  its own
virtualized   environment  and   each  operating   the  services   and
communications they  are configured  for. The  first and  main induced
challenge deals  with the  deployment issues  related to  new emerging
networks functions and whole architectures (i.e. protocol stacks) in a
virtualized networking environment. Different strategies (e.g. type of
traffic, topological models, restricted  domains) can be considered by
network operators  to achieve such  a progressive deployment  and they
are studied, implemented and evaluated in the DOCTOR project.

* Missions:
In the context  of the Doctor project, the research  work addressed by
the postdoc candidate will consist  in leading the design, deployment,
and management  of a  testbed that  will enable  long-term measurement
campaigns of  a NDN-based  telco network  deployed as  virtual network
functions. The testbed  will carry real traffic (e.g.  HTTP) issued by
students from both  Troyes University of Technology  and Telecom Nancy
toward existing  internet hosts.  The measurements performed  over the
testbed  will target  both Quality  of Service  and Security  and will
especially feed further research work on the production of a long-term
feedback  on   the  deployment  of   ICN  technologies  and   (2)  the
identification  of new  vulnerabilities  and threats  induced by  this
novel overall infrastructure.

* Skills and expertise:
The candidate is expected to present a strong expertise in Information
Centric Networking technologies (especially Named Data Networking). He
must  also be  familiar  with experimentation  studies and  especially
present  acknowledged   technical  skills,   regarding  virtualization
techniques, system administration and software development.

Salary: 1 896.58 euros per month, net salary 
Duration: 18 months
