Network virtualization provides a possible path to overcome the
increasing ossification of the Internet by enabling the introduction
of new technologies not only at the edge of the network but right down
to the core of the network. As there may be multiple virtual networks
(VNets) running different architectures and services in parallel, end
users usually want to attach to multiple VNets concurrently in order
to access all accustomed services. For instance, a user may want to
access his home TV service, his closed company network as well as his
home network even while he is abroad, staying in a hotel. This
scenario motivates the following objectives: a) The end user
wants to securely access multiple VNets from his current physical
network access, b) connections to the various VNets should be
set up automatically while also taking authentication and
authorization into account, c) the solution should not depend
on globally available IP connectivity as future networks may use
different protocols.
In this paper we briefly present the VNet framework, the end user
attachment process, and a first approach towards secure end user attachment.
