Internet Draft Dave Allan, Ericsson ed. Intended status: Informational Donald Eastlake, Futurewei Expires: August 2021 David Woolley, Telstra February 2021 5G Wireless Wireline Convergence User Plane Encapsulation (5WE) draft-allan-5g-fmc-encapsulation-08 Abstract As part of providing wireline access to the 5G Core (5GC), deployed wireline networks carry user data between 5G residential gateways and the 5G Access Gateway Function (AGF). The encapsulation method specified in this document supports the multiplexing of traffic for multiple PDU sessions within a VLAN delineated access circuit, permits legacy equipment in the data path to inspect certain packet fields, carries 5G QoS information associated with the packet data, and provides efficient encoding. It achieves this by specific points of similarity with the RFC 2516 PPPoE data packet encapsulation.

Introduction Converged 5G ("fifth generation") wireline networks carry user data between 5G residential gateways (5G-RG) and the 5G Access Gateway Function (identified as a Wireline-AGF (W-AGF) by 3GPP in [TS23316]) across deployed access networks based on Broadband Forum [TR101] and [TR178]. This form of wireline access is considered to be trusted non-3GPP access by the 5G system. The transport encapsulation used needs to meet a variety of requirements including the following: - The ability to multiplex multiple logical connections (Protocol Data Unit (PDU) Sessions as defined by 3GPP) within a VLAN identified point to point logical circuit between a 5G-RG and a W- AGF. - To allow unmodified legacy equipment in the data path to identify the encapsulation and inspect specific fields in the payload. Some access nodes in the data path between the 5G-RG and the W- AGF (Such as digital subscriber loop access multiplexers (DSLAMs) and optical line terminations (OLTs)) currently inspect packets identified by specific Ethertypes to identify protocols such asShow full document text
