MPLS Vs Point to Point

What are the advantage of using MPLS Vs. Point to Point circuits? I know MPLS offers a Mesh. Are there any other major advantages of using MPLS.


Is QoS better on a MPLS vs Point to Point? It appears to be no difference to me because QoS would just be configured on the router interfaces of a point to point circuit.



All responses are greatly appreciated. Thank You

Hi,


The answer depends on your requirements.

QoS (here: queueing) is a per interface feature and the encapsulation does not change much. The methods will also be the same (LLQ/CBWFQ).

A MPLS VPN solution offers some advantages, when connectivity between many sites is required AND many customers with overlapping IP addresses are present.

It allows a SP to setup a shared backbone resulting in lower costs per customer.

Depending on your requirements either solution could be best for your network.
