Network Slicing with Multi-Topology Routing

The deployment of 5G networks is paving the road to custom network services. It is now possible to envision the automatic decomposition of a physical network into several virtual networks to serve a wide range of user needs. This technology is also referred to as network slicing. To guarantee the strict isolation of virtual networks, it is possible to rely on underlay technologies such as Flex Ethernet (FlexE). In this demo, we present a slicing solution based on Multi-Topology-Routing (MTR). We will demonstrate how IGP weights can be designed for the embedding of a slice, described by a traffic matrix and end-to-end latency requirements, to minimize the cost of underlay bandwidth reservations.
