Content Centric Network Node Operation Identifier Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Internet Protocol (IP) based network layer faces issues such as traffic congestion due to the rapid spread of the Internet, as it relies on destination addresses, leading to inefficient data routing and network usage.
Innovation Solution
A Content Centric Network (CCN) uses operation identifiers (OIDs) in content request and delivery packets to control operations like storing, deleting, copying, updating, and forwarding content, allowing intermediate nodes to manage and route content based on content names, reducing the average transmission path and improving network efficiency.

Engineering Contradiction Analysis
1Productivity
If IP-based destination address routing is used, then data can be routed to destination nodes, but traffic congestion occurs due to large number of users concentrating on nodes having popular content
Solution Approach 1:
The patent introduces content names as intermediary identifiers that mediate between users and content sources. Instead of direct destination addressing that causes congestion, content names act as mediators that enable indirect content retrieval through intermediate nodes, distributing traffic load across the network rather than concentrating it at popular content nodes.
Solution Approach 2:
The patent changes the routing parameter from destination addresses to content names. This parameter change fundamentally alters how data is routed in the network, allowing intermediate nodes to make routing decisions based on content identity rather than destination location, thereby distributing traffic more evenly and reducing congestion at popular content nodes.
2Ease of operation
If intermediate nodes forward packets based on routing tables, then packets can reach destinations, but the average transmission path length is increased
Solution Approach 1:
The patent enables intermediate nodes to autonomously determine content routing based on content names without requiring complex routing table lookups. Each node can independently decide the optimal path for content delivery based on local content cache information, reducing the need for multi-hop forwarding and shortening transmission paths while maintaining automatic forwarding capability.
3Length of moving object
If CCN uses content names for routing, then transmission path length is reduced, but nodes must perform additional content management operations
Solution Approach 1:
The patent makes intermediate nodes multi-functional by enabling them to perform both content caching and content management operations simultaneously. Nodes that cache content locally can also manage content delivery decisions, combining multiple functions into single nodes to reduce overall network complexity while enabling shorter transmission paths through direct content retrieval.
