In the last two posts I discussed the role of FECs in MPLS networks, and implicit and explicit null labels. In this brief post I’d like to discuss MPLS label stacking, as a preliminary to a couple of ...

In certain models of inter-provider Multi-Protocol Label Switching (MPLS) based Virtual Private Networks (VPNs) spoofing attack against VPN sites is a key concern. For example, MPLS-based VPN ...

There hasn’t been much differentiation among the services available from providers with Multi-protocol Label Switching networks yet. One reason is that the operations, administration and maintenance ...

Multi Protocol Label Switching (MPLS) brings several benefits to Internet Protocol networks, including increased packet forwarding performance, traffic engineering mechanisms to maximize resource ...

Multi-protocol label switching (MPLS) deployments to date have been focused on providing traffic engineering and network-based IP virtual private network (VPN) capabilities to IP core networks, and to ...

MPLS also offered a way to “cap-and-grow” legacy network technology, in particular, Frame Relay, ATM and SONET. This allowed some SPs to upsell an enterprise offering of point-to-point Frame Relay ...
