An MPLS Engineer configures and troubleshoots Multiprotocol Label Switching (MPLS) in a telecom network. MPLS enables a consistent flow of data traffic in high-performance telecommunications networks. In this technology, data is directed from one node to another along predetermined routes as opposed to a flexible routing table. These highly-trained professionals ensure the efficiency of massive and complex networks.

In the Telecom field, the engineer provides clients with information on how to use MPLS-TE and associated features to maximize their network bandwidth. Traffic Engineering (MPLS-TE) remains essential for backbone service providers such as internet service providers (ISP).

MPLS integrates traffic engineering (TE) capabilities into Layer two and three services. The routing of IP traffic is optimized at this layer. MPLS can compress packets of several network protocols. This is why engineers and administrators describe it as multi-protocol. MPLS supports a range of access technologies, including T1/E1, ATM (Asynchronous Transfer Mode), frame relay and DSL
