It is reported that Google has covered the network solutions of data centers, servers, switches, and software infrastructure, and realized the interconnection of traffic with the world's metropolises to occupy the entire Internet traffic. Google pointed out that Italian espresso can not only bring higher performance to consumers, but also benefit the cloud service companies of Italian espresso.
Google researcher Amin. Valda and engineers. In a blog post, he said, "The existing Internet protocol cannot be provided by all connected partners, so it is impossible to provide the best usability and user experience for end users."
It is understood that Italian espresso will improve the user experience from two aspects. The first is to select the best data center based on the real-time performance indicators of automation. The second is to separate and control the flow with a single hardware router, and make a single routing decision for the aggregation of network information in the distributed system.
In fact, in the past two years, Italian espresso has been running in Google's internal production environment, handling about traffic and all new traffic. In the process of using Italian espresso, the connection point can be dynamically selected and can be rebalanced according to the actual performance data and flow. At the same time, it can also handle failure and congestion of the network or the public Internet.
As the four directions of Google's strategy, Italian espresso seems to face the biggest challenge. The other three directions are data center interconnection system (Jupiter), software definition WAN (), and network virtualization architecture (Fairy).
