IP Packet Encapsulation for ICN Network Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition from Internet Protocol (IP) networks to Information-Centric Networking (ICN) poses challenges, particularly in integrating IP-based services and devices with ICN networks, as existing IP-based applications and infrastructure require significant migration, making seamless communication between IP and ICN environments difficult.
Innovation Solution
The solution involves methods and systems that enable IP packets to be forwarded through and received from ICN networks, allowing IP-based devices to communicate within and across ICN environments by encapsulating IP packets into ICN packets using appropriate naming conventions and publish-subscribe models, facilitating communication between IP and ICN networks without requiring immediate migration of network protocol implementations.

1Productivity
If IP-based devices and applications are migrated to ICN networks, then network efficiency and in-network caching are improved, but device complexity and infrastructure migration requirements increase
Solution Approach 1:
The patent introduces an intermediary mechanism that allows IP packets to be forwarded through ICN networks without requiring full migration of IP-based devices. The system acts as a bridge between IP and ICN domains, enabling seamless communication while maintaining the simplicity of existing IP devices and applications.
Solution Approach 2:
The patent creates a universal forwarding mechanism that can handle both IP packets and ICN data packets within the same network infrastructure. This multi-functional approach allows the network to serve both legacy IP devices and emerging ICN applications simultaneously, avoiding the need for complete infrastructure replacement.
2Adaptability or versatility
If IP packets are encapsulated into ICN packets for forwarding through ICN networks, then interoperability between IP and ICN environments is improved, but packet processing complexity increases
Solution Approach 1:
The patent implements packet encapsulation where IP packets are nested inside ICN packets. This nested structure allows the ICN network to carry IP traffic while maintaining the ICN routing and caching mechanisms. The outer ICN packet header provides routing information for the ICN network, while the inner IP packet maintains its original structure for end-to-end delivery.
3Adaptability or versatility
If in-network caching and replication are implemented, then data independence from location is improved, but network infrastructure requirements increase
Solution Approach 1:
The patent enables in-network caching where intermediate nodes automatically cache and replicate data packets based on their content identifiers. This self-service mechanism allows the network to autonomously manage data distribution and caching without requiring centralized control or complex infrastructure modifications. Nodes make intelligent decisions about caching based on the ICN routing protocol.
