Edgecore ASFvOLT16

• Possible deployment scenarios• Similar to Edgecore OF-DPA• Pre-built binary package from Edgecore,

ONF or SI (system integrator)

12

Edgecore ASFvOLT16

• Future work• C++ based voltha_bal_driver• Use C++ based GRPC• In-band management support• OLT auto discovery• Expose more Maple features though BAL• Expanded use of syslog by voltha_bal_driver

19

• Accton/Edgecore• Reliable ASFvOLT16 hardware• Porting Broadcom BAL/Maple/Qumran SDK to ONL kernel for

x86_64 arch• BAL patch and patch versioning/build documentation• Redfish server support from OCP design

• Broadcom• Provided the open-source API for the BAL framework• Distributing the ASFvOLT16 BAL patch via CSP• Supporting PoC demos and driver development


20

• ONF• Edgecore adapter project kickoff• Proposal for GRPC device simulator w/Juniper C-GRPC• BAL API .proto files• Asfvolt16_olt.py adapter initial framework and adapter class

• AT&T• Use case and feature set required from BAL API

• ALTEN Calsoft Labs/Ciena• Proposal for OLT device management using Redfish client/server• Redfish client in asfvolt16_olt adapter using REST APIs• Data models for management and configuration


21

• Radisys• Leading community asfvolt16_olt adapter and in-OLT driver initiative• Developing in-OLT BAL API control driver (voltha_bal_driver)• Worked directly with Broadcom to:

• Develop understanding of VOLTHA community need for open BAL API• Negotiate required BAL API feature set• Define BAL package and patch distribution model suitable for SLA

• Worked directly with Edgecore/Accton to:• Transfer PoC result on Broadcom reference OLT to ASFvOLT16• Develop BAL acceptance test to ensure voltha_bal_driver foundation• Define BAL patch components and versioning method
