Video Session Manager for Inter-Domain Bridging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video conferencing systems face challenges in executing and managing inter-domain communication sessions due to resource inefficiencies, such as inadequate bandwidth and bridging resources, leading to failed or unattempted sessions across geographically disparate domains.
Innovation Solution
A video session manager is introduced to analyze communication session requests, select optimal bridging resources based on geographic locations, and connect endpoints via a multipoint control unit, optimizing resource utilization and session viability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video conferencing sessions are attempted across multiple geographically disparate domains, then communication coverage and accessibility are improved, but resource availability and session reliability deteriorate due to inadequate bandwidth and bridging resources
Solution Approach 1:
The patent introduces a video session manager as an intermediary system that coordinates video conferencing sessions across multiple domains. This manager evaluates available bridging resources and selects optimal resources to connect endpoints from different domains, thereby enabling cross-domain communication while maintaining session reliability through intelligent resource allocation and mediation.
2Reliability
If bridging resources are allocated to support inter-domain video sessions, then session viability is improved, but resource utilization efficiency deteriorates due to scarce and expensive shared resources
Solution Approach 1:
The patent implements dynamic resource allocation where the video session manager continuously evaluates the availability and suitability of bridging resources across domains. Instead of static allocation, the system adapts resource selection based on current session requirements, endpoint locations, and resource utilization status, thereby improving session viability while optimizing resource utilization efficiency through flexible, demand-driven allocation.
3Productivity
If optimal bridging resources are selected based on geographic locations, then resource allocation efficiency is improved, but system complexity increases due to the need to evaluate multiple attributes and constraints
Solution Approach 1:
The patent applies preliminary action by having the video session manager pre-evaluate and identify suitable bridging resources before actual video sessions are established. The system proactively assesses resource attributes, geographic locations, and compatibility requirements in advance, creating a prepared resource pool that can be quickly allocated when session requests arise, thereby improving allocation efficiency while managing complexity through advance preparation.
4Productivity
If video session management evaluates multiple bridging resources and attributes, then session optimization is improved, but operation time increases due to the evaluation and selection process
Solution Approach 1:
The video session manager performs preliminary evaluation of bridging resources and their attributes before sessions are actually needed. By pre-assessing resource compatibility, geographic suitability, and availability, the system creates a prepared framework that enables rapid session establishment. This advance preparation optimizes session outcomes while minimizing the time required during actual session initiation.
Data Source
AI summary
A video session manager and method for enabling, optimizing, and managing inter-domain video communication sessions, including telepresence and videoconferencing sessions. The video session manager is configured to receive and analyze a video communication session request from one or more endpoints; to determine the viability of a communication session based on one or more attributes of the session; and to connect the one or more requesting endpoints to start the session. The video session manager is further configured to connect the one or more requesting endpoints via a bridging resource, such as a multipoint control unit, based on one or more considerations such as geography and transmission channel utilization.
