Creating a "cloud high-speed" for the future network data center

people's life has gradually entered the cloud era. In the future, more than 80% of the business will be deployed on the cloud. Cloud DC (data center, data center) is becoming a new network traffic center. With the rapid growth of 4K video, VR and various interconnected application traffic, the network between DCs is facing great challenges; Similarly, the digital transformation of the industry is also accelerating the cloud process of enterprise DC. As the undisputed protagonist in the cloud era, digital enterprises, due to the high cost of traditional leased lines and slow network response, also choose to build or operate their own DC interconnection networks. How to build future oriented DC center interconnection has become the focus

Data migration and interconnection between

require cloud high-speed

enterprises now have more and more network traffic and data, making cloud data centers develop rapidly towards a super large capacity and distributed pattern. At the same time, the massive optical fiber and network traffic that is prone to burst require a wider pipeline for traffic buffer. In the existing large-scale data centers, it is very difficult to maintain nearly 10000 pairs of optical fibers, Moreover, it is prone to single point of failure and power consumption. For example, a supermarket has more than 10 data centers across the country, and the distance between data centers can reach more than 1000 kilometers at most. Data interaction between DCs requires highly reliable high-speed backbone between clouds. The future oriented DCI solution proposed by Huawei, 400g end-to-end DCI interconnection, systematic expansion of interconnection network bandwidth, elimination of bandwidth bottleneck between DCs, reduction of 50% of the number of optical fibers, support 2000km long-distance lossless transmission, support smooth annual bandwidth evolution, and protect investment

cloud services with low latency and sudden traffic require intelligent and flat DC interconnection networks

large enterprises usually have branches in various regions to further strengthen the implementation of certification. Different branches have their own data centers. Cross data center businesses such as large-scale games, stock trading consumes a lot of bandwidth and has very strict requirements on latency. Taking the financial industry as an example, the advantage of 1ms delay is equivalent to a US $100million increase in revenue. At the same time, businesses such as DC synchronous computing, virtual machine hot migration, disaster recovery backup and so on require network delay less than 10ms. Huawei can create a flat and fully interconnected network architecture to support one hop direct service. At the same time, the physical isolation bandwidth guarantee of the hard pipe and the three-layer to edge flat network design can meet the ultra-low delay requirements of the DC to DC bearing network

The traffic between

is sudden and unbalanced, so SDN technology needs to be used for real-time traffic optimization. Random data migration between DCs is easy to cause traffic uncertainty. For example, internet hotspot services such as 11.11 are also sudden, which will cause traffic imbalance, local link congestion, and low average utilization of the whole link. At the same time, traditional traffic engineering can not solve the problem of sudden congestion based on network traffic prediction. Huawei's traffic tuning technology can monitor and adjust the whole traffic in real time, so as to achieve load balancing between links. In addition to automatically stopping heating from 25% to 50% when the bandwidth utilization temperature reaches the upper limit, it can also adjust the traffic based on time delay and other factors to ensure the user experience

in addition, Huawei's unified agile controller can manage the entire DCI network. The end-to-end service issuance time is shortened from January to 30 minutes. It supports various northbound interfaces (cli/snmp/netconf/Yang), which facilitates the rapid integration of enterprise customers into the IT system and flexibly cope with the rapid change of DCI services

security and green energy saving are unchanging network topics

security in the cloud age is unchanging for enterprises. No matter whether enterprises build their own private cloud or adopt public cloud services, they will worry that the interconnection of cloud data centers is safer than the Great Wall built by enterprises, such as unified application, data isolation, authorization risk after agile application, etc. DCI's cloud high-speed bearer scheme provides a highly secure and highly encrypted industrial security pipeline, For example, encrypted transmission, San authentication, multi-dimensional anti attack mechanism, complex authorization, dedicated physical hard pipes, etc. make cloud data secure

cloud DC needs massive power computing and storage resources that can provide more power for China's lithium battery industry in the future. It has the characteristics of wide computer room area and high energy demand. Therefore, it is usually built in areas that are easy to expand capacity, such as low rent and rich energy. For example, Facebook chooses to build a data center in Lulea, northern Sweden near the Arctic circle. Therefore, the requirements for DCI equipment tend to be high-density ports, large capacity and high integration, So as to reduce the room rental and maintenance costs. The intelligent DCI bearing equipment provided by Huawei is highly integrated, and its ultra-low power consumption of 0.4w/gbit is only half of the industry, which can greatly save customers' operating costs

to get rich, we should first build roads. The simple slogan has pointed out the key engine of the industry's digital transformation. In the cloud era, it has gradually become a trend to build a future oriented smart cloud interconnection with cloud collaboration, super capacity, flat intelligence, security and energy conservation. At this year's Pan Asia Pacific ISP summit, Huawei released the new generation DCI product 400g osn902, which is the first similar product in the industry to support the super large capacity of 400g single board, effectively solving the challenges and operation and maintenance problems caused by the rapid growth of data center business, and helping enterprises achieve business success

as a leading Internet service provider in the world, Huawei has been constantly exploring the road of Internet development with its continuous innovation ability. It is committed to building a healthy and sustainable industrial ecosystem, working with partners to create greater value for global customers and build a better world of connections
