Abstract
n
to day's
network,
network
op erator
uses
different
middleb oxes
to
achieve
performance
and
security
challenges
in
the
network.
Some
of
the
commonly
used
examples
are
NAT
to
solve
IPv4
address
depletion
and
firewall
to
deal
the
security
attacks.
These
middleb oxes
comes
with
new
challenges.
Service
chaining
is
one
of
the
challenges,
where
a
sequence
of
middleb oxes
apply
their
service
to
particular
traffic.
Due
to
the
lack
of
available
protocols
to
route
traffic
through
middle boxes,
operators
still
rely
on
error prone
and
complex
low-level
configurations
to
steer
the
traffic
through
the
desired
sequence
of
middle boxes.
With
recent
software
defined
networking
(SDN)
architecture
and
Open Flow
protocol,
it
is
possible
to
steer
the
traffic
through
any
sequence
of
middle boxes.
