Cloud Headend Access Designations for Leaner Routing Tables

The patent segments the network access permissions by creating hierarchical groups (enterprise-level, location-level, and endpoint-level groups) with defined access policies. Instead of managing individual endpoint-to-endpoint routing rules, the system organizes endpoints into structured groups with inheritance hierarchies, where parent groups contain child groups and policies cascade down the hierarchy. This segmentation reduces routing table complexity while maintaining comprehensive network connectivity.

The patent introduces a hierarchical dimension to access control by organizing endpoints into multi-level groups with inheritance relationships. Rather than flat, pairwise access control, the system adds hierarchical layers (enterprise → location → endpoint groups) that enable scalable access management. This dimensional change allows the routing tables to scale efficiently as the network grows.

The patent implements preliminary action by pre-configuring hierarchical access policies at group levels before endpoints need to communicate. Access permissions are established at the enterprise and location group levels in advance, and these policies are automatically inherited by child groups and endpoints. When endpoints need to communicate, the routing decision is made by checking hierarchical group memberships rather than evaluating extensive individual access rules, significantly reducing processing overhead.

The patent creates universal access policies at hierarchical group levels that apply to multiple endpoints simultaneously. A single access policy configured at an enterprise group level automatically applies to all location groups and endpoints within that enterprise, eliminating the need to configure and process individual access rules for each endpoint pair. This multi-functionality reduces network resource usage while maintaining comprehensive access control.

The patent segments the scaling burden by organizing endpoints into hierarchical groups that can be independently managed. As the network scales, new endpoints are added to existing groups or new groups are created within the hierarchical structure, rather than requiring individual routing entries for each new endpoint. This segmentation allows network coverage to expand while routing table entries grow linearly rather than exponentially.

The patent adds hierarchical grouping as a new dimension to endpoint organization, transforming the scaling problem from managing individual endpoint relationships to managing group relationships. The hierarchical structure (enterprise groups containing location groups containing endpoint groups) allows the system to scale to thousands of endpoints by managing only the group hierarchy and inheritance relationships, dramatically reducing the number of routing table entries needed.
