Data Center Networking is a cliche, but the pandemic has forever changed the nature of our work. However, it has certainly turned the spotlight on technologies, processes, and practices that have been out of date for some time.
Also, the network has become a pivotal part of computing and data centers and cloud networks, which were overwhelmed by newly home-based workers and students.
Our network setup and debugging procedures. These things became increasingly important. As a result, we did not have the option of doing a truck roll or replacing a switch, says Bruce Wallis (Nokia senior director).
Data Center Networking
New types of services have been created by cloud computing. There are new types of delivery infrastructure and new types of data center demands. Currently, they have difficulty delivering reliable connectivity on demand. We now have the consumable network design for data centers.

As a result, data centers become even more vital. There is a much greater impact now. Through the lack of resources, it makes it more difficult for them to react to it. Engineers on the ground are the key resource. However, how the industry views the operation and care of data center networking has not changed significantly in the last two decades.
Some traditional network vendors have continued to market proprietary data centre operating systems and black boxes that may expose some data. Their workings are limited. The management tools that customers can use are limited, however.
There is an argument that suggests slow-moving policies are simply a reflection of stability. On the other hand, it prevents more innovative or daring organizations from choosing other protocols or building their own. If a proprietary stack is attempted to be replaced, customers will most likely be penalized by their vendors.
Black Magic Box No Longer Exists
Large parts of many hyperscalers‘ operations have been automated, including Facebook. Who are the others affected by this? Their innovation is beneficial to you. The company must move to its cloud platform. Ultimately, none of their solutions has been rushed to be exposed to mainstream enterprises, according to Wallis. The company has to run its own data centre.
The Nokia response has been to build an open-source network operating system. Nokia’s Data Center Switching Fabric uses Service Router Linux, which is part of the Service Router Linux. In addition, Nokia has designed switching hardware for their Fabric Services System.
In addition to being open, Linux is also known for its moniker. Customers can also buy or create specific elements from third parties.
In some instances, it may be required. A managed element that represents a group of functions is unquestionably beneficial. However, the network is made up of services. Defining protocols and instances of networks.
So they conform to the system-wide northbound schema. So, the functions must be modular and decomposable as the software allows. Furthermore, the plan could be to follow the type of patterns opened by DevOps.
In CI/CD, things are broken down into modules, and the changes are driven through CI/CD. It involves deploying to production and running a canary or a staggered rollout. Wallis predicts that you will start to notice all this good stuff in networking.
The Automation Of The Network People
Microservices would allow me to have ten endpoints, even if two are offline. In this case, your racks will still be offline until your switches are repaired. Whenever something goes wrong during an upgrade or when working on CI/CD, you’re being screamed at.
The network engineer says, however, that Python used to produce applications to improve their workflows. In this project, we’re trying to help people imagine creative ways to automate. They are given all the tools they need to make life easier, and it helps them drive change in their environment. Each time that individual thinks about something, they have to make a decision.
Telemetry can be opened up, and operators can choose what tooling to use. Operations are going to start identifying patterns in network outages more and more as time goes on. The remediation pipelines will soon be used.

Using this solution, the vendor will receive a better perception of what is acceptable and an actual serious problem. In addition, all errors checked automatically instead of manually. Wallis says that you can’t accomplish any of that without an underpinning infrastructure. What that means is I am receiving information at the pace I require for making decisions.
Increasing Flexibility
SR Linux provides all of this with its foundation.
- A high-speed telemetry system is needed,
- Extensions are required
- Modules are needed, not monoliths.
- Providing flexibility to customers is essential
- The user needs to add what he or she wants.
Nokia’s customers are already implementing the principles, he says. He pointed out that one of his initial customers had produced five changes to its Linux-based SR platform.
Let me give you a simple example. One of the little applications sits there monitoring telemetry for a config change. When that happens, it just adds, commits, and pushes a Git repository. He explains that it uses Git to manage the configuration on the box.
Whenever the application successfully pushes the configuration to Git, it produces a publish. GNMI can be used to verify all of the agent’s functions. The scale is different from what people are used to. There is a remediated fix applied to avoid someone getting a phone call at midnight.
