Networking
Virtualization: Next generation router
Duration:
half day
Outline
This
presentation provides an introduction to the discipline of
networking virtualization (NV). Previously, Network Virtualization
has consisted in deploying network services (VLAN, VPN, etc). One of
the emerging concepts is the OS level of virtualization which
consists in injecting multiple instances of routers on the same
network infrastructure. Network Virtualization is one of the main
concepts on which the next generation network will be based. Many
large research projects (GENI, 4ward, Federica, Onelab ) are built
on network virtualization.
The
participants will be able to differentiate between the different
virtualization techniques (para-virtualization, OS-virtualization,
application virtualization, service virtualization, etc.), and the
different levels of virtualization. They will be able to understand
the importance of virtualization and associate the type of
virtualisation with the isolation levels. They will also be able to
evaluate the tradeoffs between performance (latency and bandwidth),
security (isolation) and migration strategy.
One
of the main research issues is the sharing of firmware resources
between the different slice routers: processing, memory, I/O and
bandwidth sharing, There are many important management issues such
as configuration, performance and security (isolation) operations in
this new virtualized environment. The configuration process needs to
be enhanced to include the creation of the virtual routers instances
and the allocation of the appropriate resources for each instance.
We will demonstrate the need for a new performance model over cross-
virtualized network. In terms of security, the need for new secure
operations over this virtualized environment will be
explained.
Biography
Omar
Cherkaoui received his M.Sc. (1981) and Ph.D. (1988) from the
University of Montreal (Canada). He is a Professor of Computer
Science at University of Quebec in Montreal (Canada). He has (co)authored
more than 50 peer-reviewed technical publications, multiple invited,
keynote, and tutorial presentations, technical reports, and two
patent disclosures. He worked during four years as a researcher at
Cisco where he developed configuration and automatic test case
generation solutions for the 12000 series. He created the research
laboratory in computer networks (Lab Téléinformatique) where he
supervised more than ten projects in the domain of hi-speed network
management, Web services platform and new multimedia software (UCLP,
Validmaker, Articiel, BIOGRID,..) His research interests include
network management (standardization, protocols, configuration,
validation, modelling, testing), optical networks, etc. Omar is a
member of the technical program committees of a dozen network
management conferences.
