Solution Overview

Problem

Current packet-switched communication networks face delays due to time-consuming resource reservation processes, which are incompatible with time-constrained applications like streaming that require guaranteed bandwidth and latency.

Innovation Solution

Implementing a resource reservation management method that allows pre-reservation of resources by determining and memorizing resource reservation plans for relay nodes, using a calculation module and storage means to adapt to new reservations and pre-reservations, and employing a centralized or distributed approach to manage and update these plans across the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resources are reserved through the conventional request-and-wait process in packet-switched networks, then resource allocation can be ensured, but time delays occur that are incompatible with time-constrained applications

Engineering Contradiction:
Improveresource allocation guaranteeVSAvoidreservation delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-calculating and storing resource reservation plans in a database before they are actually needed. When a resource reservation request arrives, the system retrieves pre-computed plans instead of calculating them in real-time, thus eliminating the time-consuming calculation delay while ensuring resource allocation guarantees are met.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If resource reservation plans are pre-determined and stored for relay nodes, then reservation speed increases, but system complexity increases due to additional storage and management requirements

Engineering Contradiction:
Improvereservation speedVSAvoidplan management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system applies self-service by automatically generating, storing, and updating resource reservation plans without requiring manual intervention. The database automatically manages the reservation plans, and the system self-updates when network conditions change, reducing operational complexity despite the increased structural complexity of having a database infrastructure.

Inventive Principle:
Principle #25Self-service

AI summary

A method is intended for aiding the reservation of resources within a packet switching communication network (CR) comprising a number N of relaying nodes (S1-S4). This method consists i) in determining for certain at least of the N? nodes (S1-S4) at least one resource reservation plan Pik defined by a plan identifier associated with a stream identifier and with at least two ports, and ii) in storing for each of the N nodes (S1-S4) the various plans Pik relating to them.
