Multicast Routing via Quality of Service Manager
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional routing protocols are not suitable for ad hoc networks due to dynamic topology changes and limited bandwidth, making efficient and reliable multicast routing challenging, especially in mobile, wireless environments.
Innovation Solution
A multicast management application is used to establish and manage dynamic multicast sessions across multiple domains in an ad hoc network, utilizing a quality of service manager to coordinate traffic and ensure efficient bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional routing protocols are used in ad hoc networks, then routing functionality is provided, but the protocols cannot handle dynamic topology changes and limited bandwidth efficiently
Solution Approach 1:
The patent implements dynamic multicast routing where the Quality of Service Manager continuously monitors network conditions and adapts routing paths in real-time. The system maintains multiple alternative paths and dynamically switches between them based on current network topology, ensuring reliable multicast delivery despite frequent topology changes in mobile ad hoc networks.
2Productivity
If multicast routing is implemented across multiple domains, then bandwidth efficiency is improved, but network overhead increases
Solution Approach 1:
The patent combines QoS management and multicast routing functions into a single integrated Quality of Service Manager. This unified approach allows the system to optimize multicast routing across multiple domains while centrally managing bandwidth allocation and QoS parameters, reducing the overhead that would result from separate management mechanisms.
3Productivity
If dynamic multicast sessions are established across multiple domains, then multicast routing efficiency is improved, but coordination complexity increases
Solution Approach 1:
The Quality of Service Manager is designed as a universal coordination mechanism that handles multiple functions including multicast session establishment, path selection, bandwidth allocation, and QoS enforcement across domain boundaries. This multi-functional approach simplifies coordination by providing a single point of control rather than requiring separate mechanisms for each function.
Data Source
AI summary
A method, a device, and a system for processing a request to establish a multicast session among a plurality of communication nodes are provided. The device includes a multicast management application. The multicast management application includes instructions to receive a criterion for joining a first multicast session. The instructions further include identifying a first multicast session address and a second multicast session address using the criterion for joining the first multicast session. The first multicast session is identified using a first multicast session address. A second multicast session is identified using the second multicast session address. A responder device that is a member of the second multicast session is identified using the second multicast session address. A multicast session announcement is sent to the identified responder device. The multicast session announcement includes the first multicast session address, the second multicast session address, and the criterion for joining the first multicast session.
