MPLS Header Routing for Network Efficiency
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 for managing the expanded network.
Innovation Solution
Implementing methods and systems for routing based on path-based protocol addresses, which utilize Multiprotocol Label Switching (MPLS) network protocol headers to select appropriate identifiers for transmitting data through a network path, allowing for efficient routing by identifying region scoped, scope-specific, or node scoped network interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional IP addressing is used, then global address space allocation is simple, but routing efficiency deteriorates as network grows
Solution Approach 1:
The patent segments the global IP address space into multiple scope-specific address spaces, each associated with a particular network region or autonomous system. This segmentation allows more efficient routing decisions by limiting the scope of address resolution to local regions, thereby improving routing efficiency without requiring global address space management complexity.
Solution Approach 2:
The patent introduces scope-specific address spaces as intermediary layers between global IP addressing and local routing decisions. These intermediary address spaces act as mediators that translate global addresses into region-specific addresses, enabling efficient routing within local networks while maintaining global address space organization.
2Quantity of substance
If global IP address space is expanded, then network capacity increases, but network latency increases
Solution Approach 1:
The patent applies local quality by creating scope-specific address spaces that are optimized for local routing within particular regions. Each scope-specific address space provides localized routing information that reduces the need to query global routing tables, thereby decreasing network latency while still supporting the expanded global address space capacity through hierarchical organization.
3Productivity
If traditional routing protocols are used, then implementation is simple, but routing performance deteriorates in large networks
Solution Approach 1:
The patent implements a nested structure where scope-specific address spaces are contained within the global IP address space hierarchy. Each scope-specific address space can further contain region-specific or network-specific address spaces, creating a nested doll-like structure that improves routing performance through localized resolution while maintaining implementation feasibility through standardized nesting protocols.
