Outside-Scope Identifier Routing for Network Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The growing Internet poses challenges due to fully allocated global IP address space, leading to issues like increased network latency and inefficiencies in routing, as current distinctions between names, addresses, and routes are inadequate.
Innovation Solution
Implementing methods and systems for routing based on a path-based protocol address, which involves identifying and utilizing outside-scope identifiers to select appropriate path segments for data transmission across network paths, allowing for efficient data routing without relying on network interface identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional IP address space is used for routing, then global address allocation is straightforward, but network latency increases and routing efficiency deteriorates due to fully allocated address space
Solution Approach 1:
The patent segments the routing process by introducing path-based protocol addresses that divide the network path into distinct segments. Each segment can be independently identified and managed using outside-scope identifiers, allowing for more efficient routing decisions and reduced latency by avoiding the need to traverse the entire global IP address space.
Solution Approach 2:
The patent introduces a new dimension to address identification by using outside-scope identifiers that operate independently from traditional IP address spaces. This allows routing to be performed in a multi-dimensional address space where path segments can be identified without consuming global IP addresses, thereby improving routing efficiency and reducing latency.
2Productivity
If path-based protocol addresses with outside-scope identifiers are used, then routing efficiency is improved, but device complexity increases due to multiple identifier types
Solution Approach 1:
The patent makes outside-scope identifiers universal by enabling them to serve multiple functions: identifying path segments, avoiding network interfaces, and facilitating efficient routing. This multi-functionality reduces the need for separate specialized identifiers, thereby managing complexity while improving routing efficiency.
Solution Approach 2:
The patent introduces path-based protocol addresses as an intermediary layer between traditional IP addresses and routing decisions. This intermediary uses outside-scope identifiers to mediate the routing process, allowing for efficient path selection without directly managing complex global address spaces, thus simplifying the overall system architecture.
3Measurement precision
If network interface identifiers are used for routing, then precise interface identification is achieved, but routing flexibility is reduced due to dependency on interface-specific addresses
Solution Approach 1:
The patent extracts the network interface identifier dependency from the routing process by using outside-scope identifiers that do not include interface-specific portions. This allows path segments to be identified and routed without relying on interface-specific addresses, thereby maintaining identification precision while significantly improving routing flexibility and adaptability.
