Dynamic GRE Tunnel Setup via Aggregation Gateway Group Addressing

The patent transforms the static IP configuration approach into a dynamic one by introducing address assignment mechanisms (such as DHCP or address allocation from address pools) that automatically assign IP addresses to GRE tunnel interfaces based on the selected access network. This allows the tunnel configuration to adapt dynamically to different access networks without manual reconfiguration, resolving the contradiction between adaptability and configuration complexity.

The system implements self-service through automatic address assignment and tunnel configuration. When an access network is selected, the device automatically obtains or assigns IP addresses for the GRE tunnel interface and configures the tunnel parameters without requiring manual intervention. This self-configuration capability enhances adaptability to multiple access networks while keeping the operation simple for users.

The patent enables dynamic selection of network resources by allowing the GRE tunnel configuration to change based on the selected access network. The system can dynamically assign IP addresses from different address pools, select different routing paths, and adjust tunnel parameters according to the characteristics of the active access network, thereby improving network resource utilization efficiency while maintaining simple operation through automated processes.

The system changes key parameters of the GRE tunnel configuration (such as source and destination IP addresses, tunnel interface parameters) based on the selected access network. This parameter adaptation allows the tunnel to optimize its performance and resource utilization for different network conditions while the automation of parameter changes keeps the operation simple for users.

The patent implements dynamic address configuration for aggregation by assigning IP addresses to the aggregation interface based on the selected access network rather than configuring multiple static addresses. The system can dynamically select and assign appropriate IP addresses from address pools associated with different access networks, providing flexibility in accessing different networks while simplifying the configuration process through automation.

The aggregation interface is designed with multi-functionality to handle multiple access networks through a single interface configuration. Instead of requiring separate static configurations for each network, the universal aggregation interface can adaptively assign addresses and routes based on the active access network, providing flexibility across different networks while maintaining simple configuration.
