Logical Trunk Groups for Time-Sensitive Data in Packet Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packet-based networks face challenges in managing time-sensitive data due to physical limitations and chokepoints, which can lead to data packet loss or delay, especially when data traffic exceeds bandwidth capacity, and existing solutions require centralized control and knowledge of network topology.
Innovation Solution
The implementation of logical trunk groups in packet-based networks allows for dynamic management of calls by associating data with selected trunk groups based on identifiers, resource parameters, and performance statistics, enabling efficient resource allocation and network visibility without requiring centralized control or knowledge of network topology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data traffic increases to utilize available bandwidth capacity, then network utilization improves, but data packet loss and delay increase due to chokepoints
Solution Approach 1:
The patent implements dynamic resource allocation by allowing logical trunk groups to be dynamically created, modified, and deleted based on real-time network conditions and traffic patterns. The system continuously monitors performance statistics and adjusts trunk group configurations to optimize data flow and prevent chokepoints, enabling the network to adaptively respond to changing traffic demands while maintaining reliable transmission.
Solution Approach 2:
The system changes network parameters by associating different resource parameters (bandwidth, priority, QoS settings) with different logical trunk groups. By dynamically adjusting these parameters based on traffic type, destination, and network conditions, the system can prioritize time-sensitive data and prevent packet loss even under high utilization conditions.
2Ease of operation
If centralized control is implemented to manage network topology, then network management capability improves, but system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the network system automatically monitors its own performance statistics, identifies chokepoints, and dynamically adjusts logical trunk group configurations without requiring centralized control. The system autonomously manages network topology by creating and modifying trunk groups based on real-time conditions, eliminating the need for complex centralized management infrastructure while maintaining ease of operation.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring performance statistics from network elements and using this information to dynamically adjust logical trunk group configurations. The feedback loop enables automatic optimization of data flow paths and resource allocation, providing effective network management capability without centralized control by allowing the system to self-regulate based on real-time performance data.
3Productivity
If logical trunk groups are dynamically created and managed, then resource allocation efficiency improves, but control mechanism complexity increases
Solution Approach 1:
The patent segments the network into multiple logical trunk groups, each independently configured and managed with specific resource parameters. This segmentation allows efficient resource allocation by dedicating appropriate bandwidth and QoS settings to different traffic types and destinations without requiring complex centralized coordination. Each logical trunk group operates semi-independently, simplifying the control mechanism while improving overall resource allocation efficiency.
Data Source
AI summary
Described are methods and apparatus, including computer program products, for controlling time-sensitive data in a packet-based network. Data associated with a call is received, and the data includes an identifier associated with the data, a data source, or one or more data destinations. The data is associated with a logical trunk group selected from a plurality of logical trunk groups each in communication with the one or more data destinations over a packet-based network. The logical trunk group is selected based in part on the identifier. Calls through the packet-based network are managed based in part on the associated logical trunk group.
