Grid networking involves creating a high-speed data network that connects multiple sites, typically for applications requiring significant bandwidth. It is not tied to specific software but rather encompasses various applications that may require adjustments for optimal performance, especially when transitioning from LAN to WAN environments. For learning purposes, free software options are available, but the effectiveness of grid networking depends on the specific application and its requirements. Understanding the nuances of network transport design, such as SONET and gigabit Ethernet, is crucial for implementing grid networking effectively. Resources for further information include specialized articles and forums that delve into the technical aspects of grid networking.
