Cloud computing creates network architecture change: China triggers next wave of data center construction

The "massive data" attack is impacting the traditional network architecture, the need for greater bandwidth, higher speeds, and more capacity drives the network architecture to change, especially with the deployment of cloud computing scale, and how data centers respond to and adapt to the new network environment as new research topics.

With the rapid development of mobile Internet, the popularity of intelligent terminals, as well as social networks, video entertainment and other emerging business forms of more and more rich, so that the data flow exponentially climb. Expanding the size of the data center and strengthening the capacity of business is beyond doubt.

Bo Tong Company Infrastructure and Network division of Product Marketing Director Sujal Das, currently, the world is vigorously promoting the construction of data centers, the United States, China, Japan has become the world's largest market. In his view, China will become a major place for massive construction of data centers following the United States.

However, constrained by the circuit board space, system costs and power consumption, the expansion of the data center into a dilemma, especially the development of cloud computing and Web2.0, the data Center network infrastructure and exchange design changes fundamentally. Sujal Das believes that the network design to rapid, flat and high-capacity direction of the trend of development.

Cloud computing brings traditional network architecture changes

The surge in data traffic has put a huge strain on traditional networks, more users and business access requirements require the data center to have higher capacity and higher bandwidth, in this process, the data traffic patterns are also changing dramatically, from the server to the switch to the user's "vertical traffic" mode to more from the server to the server, A "horizontal flow" shift to storage.

In the case of Bo Tong, the change of the data traffic pattern is due to the rapid development of cloud computing, virtualization technology and Web2.0 in recent years. Data show that from 2012 to 2015 Cloud IP (note: Cloud IP refers to mobile terminals, intelligent Terminal Network generated traffic) data volume by 66% of the annual composite growth rate, in the data center overall flow accounted for 34%. Meanwhile, in the next 3 years, the public cloud workload will increase by 50% annual compound growth rate.

Sujal Das said that this is an unstoppable trend, market development and demand and new workloads will enable the network design to rapid, flat, and high-capacity direction. The construction of the data center infrastructure will be shifted from the traditional large modular switch with multiple chip components to a single chip and a fixed size switch.

He pointed out that the changes in the level of data center construction has been fully reflected in the United States Data Center construction, the construction of China's data center is expected to take the corresponding structure.

40GE Deployment Springtime 100GE time

Currently, bandwidth is considered to be an important indicator of network performance, and Ethernet will play an increasingly important role. Sujal das says that for the time being, Ethernet has been widely used in the data center and has become a mainstream location, most servers, storage devices are interconnected through Ethernet, in the United States, such as Amazon and Google and other mainstream data centers have been large-scale use of Ethernet data Center for deployment. "As data centers migrate from 10GE to 100GE, only Ethernet can better meet the high bandwidth and scalability requirements." ”

In fact, supporting greater bandwidth has become the main direction of data center development. From the initial hundred trillion to gigabit to million, Ethernet continues to meet people's fast growing needs. With the advent of the cloud computing era, enterprise-class applications and personal business gradually migrated to the network, people's demand for bandwidth is rapidly increasing, hundred trillion access, gigabit backbone of the network structure has been outdated, gigabit access, million trillion backbone will be universal.
