Abstract
In this year of the project, we developed
a new hose-model VPNs provisioning
algorithm called MTRA. The motivation for
developing MTRA is stated as follow:
Virtual private networks (VPNs) provide
customers with secure and low-cost
communication environment. One of the
popular research issues in the field of
communication networks is that how to
achieve the bandwidth requirement
specifying by customers. A new VPN
resource provisioning model called “Hose
model” has been developed. It provides
customers with flexible and convenient ways
for specifying bandwidth requirement of a
VPN. Up to now, several hose-model VPNs
provisioning algorithms have been proposed,
however these algorithms focus only on
achieving bandwidth allocation efficiency in
the case of establishing single hose-mode
VPN while meeting bandwidth requirement
specifying by customers. But in the case
where (1) the links of the network backbone
have capacity constraints and (2) the service provider needs to establish numerous
hose-model VPNs on the network backbone,
these provisioning algorithms are unable to
provide satisfied rejection ratio Therefore,
we propose a new hose-model VPNs
provisioning algorithm called MTRA in this
project. MTRA can not only deal with
numerous VPN setup requests rapidly, but
also according to the results of experimental
simulations, can reduce rejection ratio
effectively.
