IPMPLSbaserte

IPMPLSbaserte describes networks that are built around the combination of IP routing and Multiprotocol Label Switching (MPLS). In such networks, traditional IP forwarding is augmented by MPLS label switching to direct traffic along precomputed paths, known as label switched paths (LSPs). The goal is to improve scalability, traffic engineering, and the delivery of advanced services over large or complex networks.

Key components include label edge routers (LERs) at the network boundary that add or remove labels and label switch routers (LSRs) in the core that forward packets based on their labels. Labels are distributed using protocols such as the Label Distribution Protocol (LDP) or RSVP-TE, which enables explicit path setup and bandwidth guarantees. Forwarding decisions are made by combining IP routing with label switching, allowing efficient core transport and flexible service provisioning.

Common services available over IPMPLSbaserte networks include MPLS VPNs (Layer 3 VPNs), VPWS (virtual private wire service), and VPLS (virtual private LAN service), enabling customer isolation and scalable WAN connectivity. Traffic engineering capabilities allow operators to steer traffic, apply quality of service (QoS) policies, and protect critical paths with mechanisms like fast reroute. MPLS also supports multicast and integrated security considerations through network design choices.

Modern developments in this area include Segment Routing with MPLS (SR-MPLS) and Ethernet VPN approaches (EVPN), which simplify control planes and improve scalability, often in conjunction with software-defined networking (SDN) paradigms. IPMPLSbaserte remains a foundational approach for carrier networks and large enterprises seeking reliable, scalable WAN services with flexible traffic management.
