Hybrid Overlay Management for Real-Time Access-Controlled Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overlay networks struggle with real-time data transmission capabilities, scalability, and user access control, particularly in hybrid environments combining mesh-based and tree-based networks.
Innovation Solution
A hybrid overlay management server (HOMS) manages a hybrid overlay network (HON) by creating and modifying services, controlling access rights, and managing peer-to-peer data exchange, allowing flexible service type changes and data transmission rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mesh-based overlay network is used, then reliability and scalability are improved, but real-time data transmission capability deteriorates
Solution Approach 1:
The network is segmented into multiple types of peers with different functions: data peers for storage, indexing peers for metadata management, and anchor peers for coordination. This segmentation allows each segment to optimize for its specific function, with anchor peers handling real-time routing decisions to maintain speed while data peers ensure reliability through redundancy.
Solution Approach 2:
Anchor peers act as intermediaries between data peers and service peers, coordinating data transmission and maintaining network structure. This intermediary layer enables real-time transmission by pre-establishing routes and handling routing decisions, while the underlying mesh structure of data peers maintains reliability through multiple paths.
2Speed
If a tree-based overlay network is used, then real-time data transmission speed is improved, but network reliability and scalability deteriorate
Solution Approach 1:
The patent merges tree-based and mesh-based overlay network structures into a hybrid architecture. The tree structure provides fast real-time transmission paths from anchor peers to service peers, while the mesh structure among data peers provides reliability through multiple redundant paths and distributed storage.
3Reliability
If access control is implemented in hybrid overlay networks, then security is improved, but service flexibility and ease of operation deteriorate
Solution Approach 1:
The access control system is designed with universal permissions that can be applied across different service types and data categories. Service owners can set broad access policies that automatically apply to multiple resources, reducing the complexity of managing individual access controls while maintaining security through consistent permission enforcement across the hybrid network.
Data Source
AI summary
Hybrid overlay management server (HOMS) that manages a service of hybrid overlay network (HON) and a method of operating the HOMS are disclosed. The method includes: receiving a creation request for creating an HON and a service from a peer of a service owner; creating the HON and creating service information of the service; transmitting the service information to the peer of the service owner; receiving a join request for joining the HON and the service from a peer of a service user who intends to use the service; and verifying an access right of the service user, allowing the join request, and transmitting the service information to the peer of the service user, wherein the HON is a peer-to-peer overlay network over which joined peers exchange data, and the service is provided to the peer of the joined service user through the HON.
