Three Chinese Carriers in OpenDaylight City Tour

On Dec. 12-16, the ODL city tour workshop was sponsored by OpenDaylight,  China Open SDN Committee (COS), ZTE, Huawei, H3C, Cisco, VCMY and Raysystem, and hosted by Baidu, Tencent, Tethrnet and SDNLAB. It was held in four cities of China: Nanjing, Beijing, Shenzhen and Shanghai, all are within a week.

People from many technology companies joined and shared their experience in using ODL, the following slide is from Neela’s keynote, Neela listed top three companies for Internet, Telco and ICT vendors in China.  Internet companies, a.k.a BAT in China, are all members of COS and members of OpenDaylight, Tencent and Baidu are two of the four city hosts. All three Telco companies participated in ODL city tour and gave presentations. All the three ICT vendors were sponsors for this event. This shows a big enthusiasm for OpenDaylight in China.

Let’s take a closer look at the three Telco’s  approaches of SDN controller.

China Mobile

According to China Mobile, after deploy SDN, the network is expected to be more open, more flexible and more efficient , it is true for the latter two, however, compare to traditional network, to many people’s surprise,  today’s SDN deployment makes network less open.

In traditional networking, following IP standards, gateway, switch, firewall can come from different vendors, but for today’s SDN to work properly,  equipment needs to be from the same vendor as SDN controller. China Mobile’s solution to prevent vendor lock in is to develop SDN controller by themselves.  The best way to build a SDN controller is based on open source,  China Mobile selected OpenDaylight platform to develop their own SDN controller – AERO.

It is hard to ignore the gap between open source community release and commercial product release, China Mobile summarized three key areas for open source SDN controller:

  1. Clustering: high performance, high available and flexible clustering is the key.
  2. Model: common abstract model for apps and network equipment
  3. Exception handling: how to make sure data consistence during exception handling.

China Telecom

China Telecom gave a couple of use cases of how they leveraged OpenDaylight in their SDN controller; IP SDN & NFV on WAN and unified control/management for cloud/WAN.

While China Mobile is emphasized on southbound, China Telecom concentrates on northbound service plugin and Yang model, they would like northbound to be more abstracted, and they would like to have Yang model to be standardized and more mature in ODL. Their expectations of OpenDaylight are not very different than most of others, enhance core, cluster and performance.

China Unicom

Fast and automatic deployment is the main motivation for China Unicom to adapt SDN/NFV. At Shanghai, China Unicom gave an presentation of  SDN requirements from China Unicom and Practice of ODL through A-Network.

China unicom divided the controller into two layers, one is very like domain controller, it is vendor specific, the other is like super controller, it is ODL based and controls domain controllers.

The controller in red box is Huawei controller and in blue box is Cisco controller, both controllers connects to their own equipment as well as other vendors equipment through Netconf/PCE/BGP-LS protocols. On top of vendor specific controllers, there is one control system, which controls controllers.

Summary

Clustering, YANG modeling, performance and stability are the common interests of almost everyone who participated the ODL city tour, we should combine the strength of community and members, to build a robust HA open source SDN platform that can be leveraged by many many companies and people.

At last, thanks again for organizers and sponsors for this ODL city tour event, it has been a huge success and we keep the momentum for fast SDN deployment.

OpenDaylight Project Expands in China with Baidu

Chinese tech giant to adopt OpenDaylight’s open SDN platform and rapidly deliver new AI services as mobile adoption continues to grow in China

SAN FRANCISCO, December 8, 2016–The OpenDaylight Project, the leading open source platform for programmable, software-defined networks (SDN), today announced that Baidu, the leading Chinese language Internet search provider, has joined the project at the Silver level. This follows a recent announcement by Baidu to open source one of its key machine learning tools, PaddlePaddle, and demonstrates the company’s continued commitment to open source.

Growing mobile markets in China over the past several years have connected more people to the Internet and opened up tremendous opportunities and venues for new business platforms and channel strategies in the region. Baidu is advancing Artificial Intelligence (AI) as the next stage of the Internet and is using deep learning to enable new technologies for autonomous driving and e-health services. The OpenDaylight platform will enable Baidu to optimize and automate their network.

“Leveraging an open SDN platform enables us to be a more nimble organization and rapidly deliver new services that meet the changing needs and diverse interests of our users and customers,” said Liu Ning, System Department Deputy Director at Baidu. “We are pleased to join the OpenDaylight community and support OpenDaylight as the de facto standard for SDN.”

Additionally, Baidu’s Liu Ning joins the OpenDaylight Advisory Group to provide technical and strategic guidance to the OpenDaylight Technical Steering Committee and OpenDaylight developer community based on the challenges of running a real-world network.

China’s three biggest internet companies – Baidu, Alibaba and Tencent – have all joined the OpenDaylight project. By leveraging the OpenDaylight platform to manage network agility and interoperability via SDN, these organizations will be better equipped to capture new revenue opportunities and handle the increasing demands their networks are facing.

“Baidu’s contributions will be very beneficial for the OpenDaylight community as well as the industry as a whole,” said Neela Jacques, Executive Director of the OpenDaylight Project. “China is quickly becoming a hub for open source leadership and innovation. Baidu’s adoption of OpenDaylight will build on that momentum and inspire other Chinese companies to leverage open source technologies to drive rapid development, increased agility and cost savings.”

Baidu will be hosting an OpenDaylight Workshop in Beijing on Tuesday, Dec. 13. The event is part of OpenDaylight Days, a series of workshops that will be taking place in various cities across China from Dec. 12-16, 2016. Additional information including registration is available here.

Baidu, Inc. is more than just a leading Chinese-language Internet search provider; its Baidu.com domain is the largest website in China and the fourth largest website globally while the “Baidu” brand is one of the highest-ranking and most valuable brands in China. The company is taking AI to the next stage through its deep learning technology and research in image recognition, speech recognition, natural language processing, robotics and big data. The company also serves as a media platform for online marketing customers.
