# Network GLB

Network Global Load Balancer (NGLB) is a networking solution that distributes Internet traffic across multiple servers located in different geographic regions. NGLB acts as a “traffic coordinator” on the Internet, ensuring that user requests are routed to the most appropriate server. This helps improve access speed, enhance reliability, and increase the scalability of applications.

#### Key Features of Network GLB:

* **Global Traffic Distribution:** NGLB distributes traffic across servers in multiple geographic locations, reducing latency and improving access speed for users worldwide.
* **Load Balancing:** NGLB evenly distributes incoming traffic among servers, preventing server overload and ensuring stable performance.
* **Geolocation routing:** NGLB identifies the geographic location of users and routes traffic to the nearest server to minimize latency.
* **Health check:** NGLB continuously monitors server health and automatically removes unhealthy servers from the traffic distribution process.
* **Failover:** If a server becomes unavailable, NGLB automatically redirects traffic to the remaining healthy servers, ensuring service availability.
* **Flexibility:** NGLB supports various load balancing algorithms (such as Round Robin and Least Connections), customizable routing policies, and multiple network protocols.
* **DNS Integration:** NGLB typically works closely with DNS systems to route requests to the appropriate server IP addresses.
