The Architectural Blueprint of SRv6 Mobile User Plane (MUP)

Traditional 5G user plane networks are held back by the heavy, legacy GPRS Tunneling Protocol (GTP). GTP creates intense encapsulation overhead, isolates the mobile core from the transport core, and restricts service scaling.

🛠️ The Structural Blueprint: SRv6 Mobile User Plane (MUP) flattens this multi-layered bottleneck by mapping 5G Session Management rules directly into standard IPv6 Segment Routing attributes.

How SRv6 MUP re-engineers mobile operator topologies:

➡ GTP Decapsulation at the Edge: Translates standard GTP-U packets from legacy gNodeBs straight into stateless SRv6 SIDs at the cellular edge.

➡ Unified Segment Routing Fabric: Merges 3GPP mobile core functionalities natively with the underlying transport layer.

➡ Line-Rate Session Processing: Core routers forward mobile user traffic using hardware-accelerated routing tables rather than processing deep, nested tunnel layers.

Eliminate the legacy GTP tax and turn your mobile infrastructure into a high-performance, programmable network asset.
