Mapping Server for Seamless Mobility in Information Centric Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information centric networks face challenges in providing seamless mobility to mobile producer nodes, leading to temporary disconnections due to the need for re-establishing connections and updating states at routers or controllers when the mobile producer moves within or between networks.
Innovation Solution
A method is implemented in the network component of an information centric network that involves receiving request messages with mapping point parameters, updating these parameters as the mobile producer node moves, and forwarding requests using the updated parameters, allowing requests to be directed to the mobile producer's current location without relying on content routers or controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ICN uses host address-based packet delivery, then packets can be delivered from source to destination using end-to-end principle, but mobility support is poor and temporary disconnections occur when mobile producer moves
Solution Approach 1:
The patent introduces a mapping server as an intermediary between requesting nodes and mobile producer nodes. The mapping server maintains mapping point parameters including location-based metrics and updates them as the mobile producer moves. This intermediary resolves the contradiction by decoupling the delivery mechanism from direct host address routing, enabling continuous connectivity through location-based forwarding while supporting mobility without temporary disconnections.
2Speed
If ICN implements content caching to reduce congestion, then delivery speed improves, but device complexity increases due to state management at routers
Solution Approach 1:
The patent extracts the state management functionality from content routers by introducing a separate mapping server. The mapping server maintains mapping point parameters and location-based metrics, while content routers focus on forwarding packets using location information. This separation reduces device complexity at routers while maintaining the speed benefits of content caching and location-based forwarding.
3Reliability
If ICN uses dedicated controllers to monitor host mobility, then seamless mobility can be achieved, but device complexity and operational overhead increase
Solution Approach 1:
The patent implements a self-service mechanism where the mobile producer node autonomously updates its location information by sending packets with updated mapping point parameters to the mapping server. The mapping server passively receives and processes these updates without requiring active monitoring or control logic. This approach achieves seamless mobility while minimizing controller complexity and operational overhead.
Data Source
AI summary
The disclosure relates to technology providing seamless mobility to a mobile producer node. A request message is received from a requesting node in an information centric network. The request message includes mapping point parameters that have an identifier to identify a mapping server that serves requests targeting the mobile producer node and location-based metrics of the mobile producer node. The mapping point parameters are updated when the mobile producer node moves from a first network component to a second network component, and the updated mapping point parameters are provided to the requesting node in a response message sent from the mobile producer node. The request message may then be forwarded from the requesting node to the mobile producer node using the updated mapping point parameters.
