Network Element Aggregating IP QoS Statistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale Next Generation Networks (NGNs), the existing methods for monitoring end-to-end Quality of Service (QoS) and bandwidth of Real-time Transport Protocol (RTP) streams lead to repeated statistical messages, overwhelming network bandwidth and management devices, and fail to clearly express the historical IP QoS between Media Gateways (MGWs).
Innovation Solution
A method and system where a network management device sends correspondences between a local and remote network element, allowing the local element to calculate and statistically process performance parameters, reducing redundant message reporting and optimizing network performance measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the MGW makes statistics of the QoS value to each remote IP address respectively by using the statistical method of the IP QoS in RTCP/RTP protocols, then the IP QoS between each two MGWs can be measured, but the number of statistical messages increases in geometric progression, overloading network bandwidth and management devices
Solution Approach 1:
The patent merges multiple IP address statistics into a single aggregated statistical message. Instead of reporting QoS values for each individual IP address pair separately, the system combines statistics from multiple IP addresses between the same two MGWs into one consolidated message, dramatically reducing the number of messages while preserving essential QoS information.
Solution Approach 2:
The patent creates a universal statistical message format that can represent QoS information for multiple IP address pairs simultaneously. This single message structure serves the function of multiple individual statistics reports, allowing the system to handle large-scale network monitoring without proportional increases in message volume.
2Quantity of substance
If multiple IP addresses are configured between MGWs for high bandwidth, then the network capacity is improved, but repeated statistics to multiple IP addresses cause statistical straggling and increase processing load
Solution Approach 1:
The patent combines statistical processing for multiple IP addresses into a single unified process. The statistical message aggregates QoS data from multiple IP address pairs between the same MGW pair, eliminating the need for separate processing of each IP address and reducing computational complexity.
3Loss of information
If detailed statistics are reported for each IP address pair, then comprehensive QoS data is obtained, but the bandwidth of management channel is occupied and processing load increases
Solution Approach 1:
The patent merges multiple detailed IP address statistics into a single aggregated message that preserves essential QoS information while reducing message volume. The consolidated statistics include key metrics such as total packet loss, jitter, and delay across all IP address pairs, maintaining information quality while reducing bandwidth consumption.
