**More than an irrational number or a delicious treat**

## The Exponential Power of Pi

What do network routing algorithms, data center design, and internet security protocols have in common? They all rely on the power of π! Pi is an irrational number that has fascinated mathematicians for centuries. It plays a role in many aspects of technology, due to its unique properties. Today, let’s explore some of the ways π is used in technology and how it’s applied to network infrastructure, data centers, and internet security.

**Six Flavors of Pi Powering the Network Infrastructure**

When it comes to technology solutions, partners say their customers want Pi. The TD SYNNEX Technology Ecosystem Benchmark Report uncovered that security, networking and data center modernization are among the most frequently requested technology solutions.

**Data center design:** Pi is used in data center design to optimize the placement of servers and reduce latency. By calculating the distance between servers using Pi, engineers can determine the optimal layout for a data center to minimize the time it takes for data to travel between servers.

**Network routing algorithms:** Pi is used to calculate the shortest path between two points on a network. This is important for routing traffic efficiently and reducing latency. By using Pi in the calculations, network engineers can accurately determine the distance between nodes and calculate the shortest path.

**Internet security protocols:** Pi is used in various internet security protocols, including cryptographic algorithms, such as RSA and elliptic curve cryptography. Pi is applied in algorithms to generate the random numbers that make up cryptographic keys. These keys are used to encrypt and decrypt data transmitted over the internet, providing secure communication.

**Load balancing algorithms: **Load balancing algorithms distribute incoming network traffic across multiple servers to prevent any one server from being overloaded. Pi is used in algorithms to generate a random value used to select the server to handle each incoming request. By using Pi-generated values, the load balancing algorithm ensures requests are evenly distributed across all available servers.

**Bandwidth allocation: **Pi is used to calculate the maximum throughput of a communication channel. Maximum throughput is calculated by dividing the bandwidth of the channel by the signal-to-noise ratio. This is determined by using Pi in the formula for Shannon’s Channel Capacity Theorem. This calculation helps engineers determine the maximum amount of data that can be transmitted over a communication channel.

**Network monitoring:** Pi is used to calculate the frequency and period of network traffic patterns. This information identifies potential network issues, like network congestion or security threats. By analyzing network traffic patterns using Pi, network administrators can identify patterns of activity that could indicate a problem and take corrective action.

Pi is fascinating mathematical concept with many practical applications, from solving complex equations to powering the internet. Really Pi is part of the fabric of our lives and taking a day to celebrate its contributions to science and technology.

Pi makes a lot possible. If you plan to celebrate 3/14 with an apple, cherry or lemon meringue pie, as you search for the perfect recipe, pause and give thanks to the irrational number and its contribution to the internet.

## Other kinds of PI

In your hunt for the perfect pie recipe to celebrate Pi Day, your curiosity might lead you to search for other applications of the irrational number in technology. And while the ratio of the circumference of a circle to its diameter is pervasive, so are acronyms for P.I.
