Abstract:
In models of Single-AS and inter-provider Multi- Protocol Label
Switching (MPLS) based Virtual Private Networks (VPNs) Lawful
Intercept is a key requirement. For example, MPLS-based Layer 3 VPN
models do not have any provider provisioned methods of lawful
intercept that are comprehensive, quick and easy to provision from
one single point. More particularly the auto-provisioning of lawful
intercept for all sets of streams travelling between VPN sites and
consequent re-direction of these streams to the appropriate
government network has not been covered without multiple instances of
having to configure the intercept at various points in the network
both in the Single-AS case and the Inter-Provider VPN case.
In this paper, we propose a technique which uses a set of pre-defined
labels called Lawful Intercept labels and a method for provisioning
lawful intercept amongst the various PE devices using these labels
both in the Single-AS and the inter-provider VPN cases. A single
point of action is the key to this idea. The intercepted traffic is
mirrored on a PE or a whole set of PEs or on all the PEs
participating in the VPN. A technique called the Domino-effect
provisioning of these Label-based Provider Provisioned Lawful
Intercept mechanism is also outlined.
