Description: The Gateway Load Balancing Protocol (GLBP) is a network protocol designed to distribute traffic among multiple gateways in a network. Its main goal is to enhance the availability and efficiency of data traffic, allowing multiple routers to act as a single logical gateway. GLBP enables network devices to share the traffic load, reducing the risk of overload on a single router and improving network resilience. This protocol assigns a unique virtual router ID to a set of routers, where one becomes the ‘active virtual gateway’ and the others are ‘standby virtual gateways’. Through a load balancing algorithm, GLBP distributes traffic requests among available routers, optimizing resource usage and ensuring faster responses to user requests. Additionally, GLBP provides automatic failover, meaning that if the active virtual gateway fails, one of the standby virtual gateways can take over its function without service interruptions. This approach not only enhances traffic efficiency but also increases network reliability, making it a valuable solution for enterprise environments that require high availability and performance.
