1 SDN-Enabled Broadband Access (SEBA) SEBA RD Team Thomas Moore (AT&T) December 4, 2018

2 SEBA Rationale, Assumptions & Architecture Operator-Driven Deploy in 2018 Common infrastructure Containers run in Kubernetes as cloud underlayer Edge cloud orchestration option for convergence to Akraino EdgeStack (Linux Foundation) Enable any Northbound CAP - Legacy OSS and new systems like ONAP Integrate to existing networks as well as greenfield Aggregation and Service Gateway (ASG) enables Wireline Broadband Network Gateway (BNG) or Wireless PDN Gateway (PGW) 2

4 High Level SEBA AT&T Workflow A high level overview of the AT&T workflow for SEBA and look at the ongoing AT&T field trials Michael Gasser (AT&T) December 4, 2018 Reference: SEBA AT&T Workflow Link: 4

5 AT&T SEBA Workflow POD consists of: 3 Compute nodes 1 AGG Switch Up to 16 x 16 XGS PON s Software Stack 5

6 Slot 1 Edge Core SN: xxxxxxxxxxxx Abstract OLT Name: PLANOTX3400OLT1 Agg Switch 1 Uplink: 20 Slot 1: 1 Slot 2: 2 Slot 3: 3 Slot 2 Edge Core SN: yyyyyyyyyyy Slot 3 Edge Core SN: zzzzzzzzzzz Builds a representation of the POD hardware as an OLT with uplinks, slots, and ports. Each port supports a split of ONTs Provides a consistent model to OSS/BSS with various hardware configurations Support provided for 1 port, 16 port, 24 port, etc. OLTs For AT&T the model will provide 16 ports per slot and up to 16 slots. ONT split ratio can be 1 of 2 models 32 ports with coexistence of GPON + XGS-PON 64 port greenfield 6

9 AT&T vaccess Field Trial AT&T has deployed the ONF s Software-Enabled Broadband Access (SEBA) open source software solution in two geographic locations enabling more than 120 living units. vaccess Trial POD This strategic open source architecture is deployed using common Compute servers as used in a Data center, and an Open Compute Platform (OCP) based virtualized OLT (volt). The vaccess project helps realize the D2.0 architecture enabling us to support multiple wireline, wireless access technologies at the edge of the network which strategically minimizes latency for customer applications. CO Trial Details: Our first application is 10G XGS-PON which will provide Multi-Gbps services for residential and business customers on the shared fiber 9
