In the current innovative network, to cope with the increased require-
ments of customers, there is a rapid increase in the development of dierent
protocols and applications. With such increase in networking technology,
the security constraints are becoming more and more severe, reducing the
accessibility to the actual network for implementing new protocols. This
scenario forced for an urgent need of a technology, which can help the re-
searchers to implement their developed protocols in the network without
inuencing the production trac. This need resulted in a concept called
network isolation. This is achieved by VLAN or SDN technologies.
In this study, we investigate the performance of VLAN and an API
of SDN in the context of establishing dynamic link, in switching setup. For
such a link creation, dynamic VLAN (dVLAN) is used in the former case
and OpenFLow protocol is used in the later scenario. The main focus in this
study is to compare the dynamic behavior of both the protocols in layer-2
context by measuring network level performance metrics of each protocol.
Some of the features like, vendor independency and software independency
is taken into account while measuring the performance metrics.
In order to evaluate the performance, an experimental testbed is
implemented. The network level performance metric called protocol setup
time is measured. It is the time taken by each protocol to setup an active
link between two end-hosts. A two-tire network architecture is implemented
with the mentioned features.
From the analytical and statistical results obtained, OpenFlow re-
sulted in performing relatively better when compared to dynamic VLANs.
By carefully examining the protocol setup time of OpenFlow against dVLAN,
OpenFlow took less time when compared to dVLAN resulting in faster exe-
cution in enabling connectivity. On the other hand, the analytical study on
the two protocols reects the simplicity exhibited by dVLAN over Open-
