Networks of Modern Data Centers with CLOS Architecture

In recent years, we have witnessed a rapid increase in the use of applications and services that are primarily accessible through the public cloud. Similarly, interest in the availability of services within individual organizations hosted in private or hybrid clouds is also growing.

This trend brings numerous advantages, such as increased agility, scalability, elasticity, and access to data and services from anywhere, at any time. However, it requires an appropriate and robust data center infrastructure to ensure the smooth operation and security of these services.

This thesis is dedicated to describing modern concepts, individual components, and the architecture of networks in modern data centers. The thesis focuses initially on modern trends and the impact of cloud computing on the development of data center network architecture, as well as a historical overview of various architectural concepts.

Following this, there is a description of suitable protocols and technologies necessary for ensuring the efficient operation of cloud services, requiring a modern data center architecture such as the CLOS architecture.

This architecture enables high performance, reliability, and scalability of networks, which is crucial for supporting heavy workloads and the rapidly changing needs of service users. Additionally, it allows for easy network management and improved security, which is essential for data protection and ensuring compliance with various standards and regulations.

The establishment and maintenance of modern network infrastructure in data centers are becoming increasingly important. This includes the use of advanced technologies such as virtual environments, automation, and monitoring tools that enable efficient management and resource optimization.

This ensures the reliability, security, and high availability of services, which is crucial for end users’ satisfaction. The theoretical foundations and possibilities of using artificial intelligence in network management and monitoring are also presented.

In the final section of this thesis, an example of such a network from practice is presented, encompassing all the features of modern data center architecture.
