Integrated Backhaul Transport for 5Gs

Abstract

A mechanism is disclosed operating a transport network function (TNF) as part of a fifth generation wireless (5G) virtualized control plane. The mechanism includes receiving a request to compute a traffic engineering (TE) path in a 5G transport network for a packet data unit (PDU) session, the request received from a 5G virtualized control plane function via a service based interface (SBI) bus. Network topology information for the 5G transport network is obtained via a northbound interface (Nn). A TE path across the 5G transport network is computed for the PDU session based on the network topology information. A TE path identifier for the TE path computed for the PDU session is returned via the SBI bus.

1 . A method implemented in a network, the method comprising:
 operating, by one or more processors, a transport network function (TNF) as part of a fifth generation wireless (5G) network;   receiving, by the processors, a request to compute a traffic engineering (TE) path in a 5G transport network for a packet data unit (PDU) session, the request received from a 5G control plane function via a service based interface (SBI) bus;   obtaining, by the processors, network topology information for the 5G transport network;   computing, by the processors, a TE path across the 5G transport network for the PDU session based on the network topology information; and   returning, by the processors, a TE path identifier for the TE path computed for the PDU session, the TE path identifier returned via the SBI bus.
