Innovation Solution
The system includes a relay server with a relay group information sharing unit, routing information creation unit, and inter-relay server connection processing unit, enabling dynamic creation of virtual networks by sharing relay group, server, and routing information, and establishing routing sessions through routing control points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If relay servers share identification information of client terminals across the entire network, then communication among client terminals is enabled, but the system lacks dynamic virtual network creation capability
Solution Approach 1:
The patent segments the network into multiple virtual networks (relay groups), where identification information is shared only within each virtual network rather than across the entire network. This is achieved by creating separate relay group information tables for different virtual networks, allowing dynamic creation and isolation of virtual networks while reducing unnecessary information sharing complexity.
Solution Approach 2:
The patent implements dynamic virtual network creation by allowing relay servers to join or leave relay groups at runtime. When a relay server joins a relay group, it dynamically receives relevant identification information for that virtual network. This dynamic approach enables flexible virtual network creation without requiring pre-configured static information sharing across all servers.
2Reliability
If relay servers share all relay server information including activation status, then routing decisions can be made accurately, but information transmission overhead increases
Solution Approach 1:
The patent applies local quality by having each relay server maintain and share only the specific activation information relevant to its local relay group context. Instead of broadcasting all activation information network-wide, each server shares activation status only with members of its relay group, reducing transmission overhead while maintaining routing accuracy within each virtual network.
Solution Approach 2:
The patent performs preliminary action by pre-organizing relay servers into relay groups with predefined routing relationships. This allows routing decisions to be made based on pre-established group information, reducing the need for continuous extensive information exchange and lowering transmission overhead while maintaining accurate routing within groups.
3Adaptability or versatility
If routing information is shared among all relay servers, then routing sessions can be established across the network, but network expandability is limited
Solution Approach 1:
The patent segments routing information management by creating separate relay group information tables for different virtual networks. Each relay server maintains routing information specific to its relay group, allowing independent management and expansion of each virtual network without affecting others, thus improving network expandability while managing complexity through segmentation.
Solution Approach 2:
The patent implements universality by designing a relay server that can belong to multiple relay groups simultaneously. This multi-functionality allows a single relay server to participate in multiple virtual networks, enabling network expansion without requiring dedicated servers for each virtual network, thereby reducing overall system complexity while improving expandability.

AI summary
In a relay server, a routing group information sharing unit shares routing group information, which is formed by grouping routing control points comprising two or more among a first relay server in a relay group, a second relay server in the relay group, a client terminal connected to the first relay server, and a client terminal connected to the second relay server, among the first relay server, the second relay server, the client terminal connected to the first relay server, and the client terminal connected to the second relay server. A routing session establishment unit establishes a routing session, which enables a communication packet to be routed via the routing control points, for each group indicated in the routing group information while referring to relay server information.
