Reflections of Programmers About Local Networks

While the local area networks (LAN) are one of the basic stones of today’s software architecture, many developers are making critical mistakes on this. The article released by Dreamstation Systems reveals the points that the programmers are often burned about LAN and shows how these misunderstandings can lead to problems.

Common illusions of programmers can be listed as follows:

• **The assumption of the network availability is always guaranteed, if the voters and delays are real.
• belief that all devices can transfer data at the same speed; protocol and hardware differences affect it.
• The thought that communication on LAN with Localhost will show the same behavior; there are different from security and performance angles.
• To believe that DNS resolution will always be consistent; it can change according to network configuration.
• The blood of delay and bandwidth problems will be resolved at the software level; physical infrastructure plays a critical role.

These misunderstandings are especially important when designing distributed systems** The developer may not see real network problems that may occur in the production environment in the test environment and may eventually encounter scalability and reliability problems.

The article highlights that programmers understand LAN structures better, build more robust and error-tolerant systems. This information consists of valuable warnings for both system architects and backend improvements.
