It can be used for a number of things such as: *Provide multi-protocol local networks over a single-protocol backbone *Provide workarounds for limited hop counts networks. A [ Read More ]

In this post, we will talk about MPLS (Multiprotocol Label Switching) which is an open standard base protocol capable of transporting different type of either L2 or L3 payloads. We will look at facts in terms of the origin of the protocol, some of the different design options we have available today and how to [ Read More ]
