Scalable and Resilient Network Traffic Engineering Using Erlang-based Path Computation Element

Scalability and resiliency are two significant requirements for upcoming beyond 5G networks. As network resource usage is expected to increase, scalability of the control plane handling the required amount of network resources is also necessary. Moreover, resiliency of cloudified control plane software mechanisms is also a requirement. This demonstration presents an Erlang-based Path Computation Element (PCE) able to perform traffic engineering for Segment Routing. Specific scalability and resiliency properties are provided in order to support transport connectivity in beyond 5G networks.
