China's first 25G test verification test bed officially launched!

With the gradual arrival of various technologies such as big data and the Internet of Things, business complexity has been on the increase. The future of a variety of cluster services, the network bandwidth, low latency, the demand is higher and higher. 25G's technical features to meet the current CPU and NVMe and other network needs, and build 25G test verification test bed, to solve the compatibility and stability of related equipment and other issues, the perfect and development of the 25G industry chain is imminent.

In 2014, IEEE formally set up a special research group to promote the creation of 25Gbps Ethernet standard. In June 2016, the 25G standard achievement "IEEE Std 802.3by?" Was released. In September 2016, ODCC released the Technical Specification for 25G TOR Switches. In May 2017, ODCC released the 25G AOC Technical Specifications. Over the same period, ODCC initiated the joint co-operation of users and vendors in Baidu, Alibaba, Tencent, China Telecom, Telecom, Mobile, Intel, Cisco, Melacca, Delta, Finisar, Lenovo, Construction, the first 25G test verification test bed officially started!

Since the founding of ODCC Network Working Group, under the leadership of the team leader and Yang Zhihua, senior technical manager of Alibaba, Baidu, Tencent, mobile and telecom have been set up to date. Since the founding of ODCC Network Working Group, 10G AOC, 25G TOR, 25G AOC, 40G optical module and a series of technical specifications for the development of Internet technology network has played a very good lead role.

25G is a common need of Internet companies, for which ODCC held a 25G theme salon, chaired by Dr. Li Jie ODCC policy committee.

Lu Rui, an architect from Alibaba, shared Ali's application in 25G. Ali started a long time ago to evaluate the 25G program, but has been exploring for various reasons. The test is particularly important for the development of 25G, through the test can find many problems, is conducive to the subsequent large-scale deployment. It is recommended that the ODCC focus on integration testing such as the effect of long-term business operations, performance under different ambient temperatures, and related alarm functions and plug-in effects.

Chen Hua, a senior systems engineer from Baidu, introduced the case of Baidu self-study 25G switch. Compared with the traditional TOR, Baidu self-study 25G using the x86 architecture, hoping to achieve future unified management with the server part, to improve efficiency. In addition to the introduction of BMC out of band management system on TOR, this will be conducive to the further analysis and processing of the fault. For the moment, testing accounts for nearly half of the workload in the development of new products. Baidu is willing to share the relevant test specifications, together with the industry to establish and perfect the 25G industry chain, but also help to speed up the deployment of Baidu in the 25G speed.

Li Xiang, network architect from Tencent exchanged Tencent's 25G development ideas and plans, hoping the industry can work together to promote the development of 25G industry, with particular hope to promote cost reduction in order to promote the large-scale deployment of 25G.

ODCC testing and certification team leader, Guo letter senior manager of Guo Liang and test bed project manager, Baidu *** Cheng Chuan-sheng introduced the overall planning of the project. From the actual deployment, due to differences in the understanding of the standard manufacturers, resulting in 25G compatibility there are still some problems. According to the 802.3by standard issued by the IEEE, it hopes to conduct comprehensive testing research on 25G related products from various aspects including physical layer, 2/3 layer and 4/7 layer through ODCC's 25G test bed. After the perfect testing, related products can be exposed before the official deployment and solve many potential problems, including compatibility, and promote 25G commercial and large-scale process.

From the 25G industry chain, Intel, Arista, Melath, Ruijie Networks, Cisco, Ixia, Delta Electronics, Inventec, Huawei, Lenovo, IBM, Finisar, Suzhou Xuchuang, Wuhan Optical Motion, Hong Teng Precision, Pacific Technical experts such as manufacturers provide a lot of meaningful development proposals for the 25G test bed project.
