Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current routing technologies face challenges in scalability and network delays due to increased media-based applications and traffic, particularly burdening backbone routers, necessitating a solution for high-speed IP packet forwarding and easy implementation on existing networks.
Innovation Solution
A novel protocol, ROACM (Route Once And Cross-Connect Many), which enables high-speed IP packet forwarding by adding a dynamic virtual circuit header that contains relevant information for cross-connecting IP packets at the data link layer, allowing for efficient routing and reducing the need for high-power processing and routing/switching protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional routing protocols are used to forward IP packets through multiple routers, then packet delivery to destination is achieved, but network delays increase and routing infrastructure cost increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing virtual circuits and pre-computing routing paths before actual data transmission occurs. Routers advance routing decisions and reserve bandwidth in advance, allowing packets to be forwarded without real-time routing computations, thereby reducing network delay and increasing forwarding speed.
Solution Approach 2:
The patent introduces virtual circuits as intermediaries between source and destination routers. These virtual circuits act as mediators that pre-establish dedicated paths through the network, eliminating the need for real-time routing decisions at each hop and significantly reducing packet transmission time.
2Adaptability or versatility
If more routers are added to expand network coverage, then network scalability improves, but backbone router stress increases
Solution Approach 1:
The patent segments the routing function by introducing intermediate virtual circuit switches that handle packet forwarding locally. This segmentation distributes the routing burden away from backbone routers to edge routers and virtual circuit switches, allowing network expansion without proportionally increasing backbone stress.
Solution Approach 2:
The patent employs copying by creating virtual circuit instances that replicate routing functions at multiple levels. Virtual circuits copy the routing decision-making process to edge routers, allowing the backbone network to scale while distributing processing load to prevent bottlenecking at core routers.
3Ease of operation
If routing decisions are made at each router hop, then flexible routing is achieved, but processing power requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-computing and pre-establishing virtual circuit paths before data transmission. Routing decisions are made in advance at the source or at intermediate switches, eliminating the need for real-time processing at each router hop, thereby reducing processing power requirements while maintaining routing flexibility.
Solution Approach 2:
The patent replaces the mechanical routing process (where each router independently processes and forwards packets) with a virtual circuit-based system where routing decisions are encoded in the packet header and executed through simple cross-connection operations at switches, significantly reducing processing power requirements.

AI summary
The present invention relates generally to high-speed packet forwarding (switching/routing) system such as the present IP (Internet Protocol). More particularly, the invention encompasses a protocol that includes having the capabilities of high-speed IP packet forwarding to over come network delays. The invention further includes a protocol that allows for an easy and transparent implementation on current IP networks or any packet switching system/device so that one can route once (at a certain level) and cross-connect many (at a lower layer) (ROACM).
