Core Network Traffic Handling via CCA Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing encrypted data traffic in core network domains makes it difficult to determine data traffic characteristics, which are essential for optimizing traffic handling and ensuring Quality of Experience (QoE) and Quality of Service (QoS).
Innovation Solution
An apparatus is configured to receive data traffic from outside the core network domain, analyze it using deep packet inspection, and obtain congestion control algorithm (CCA) information from a mapping configured by the data traffic sender. This information is used to perform traffic handling actions that optimize data traffic handling based on the CCA type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data traffic is encrypted to enhance security, then security is improved, but the ability to determine data traffic characteristics deteriorates
Solution Approach 1:
The data traffic sender performs preliminary action by configuring a mapping between data traffic identifiers and CCA information, and providing this mapping to the core network domain before traffic handling. This allows the network to obtain CCA information without needing to decrypt the actual traffic content, thus maintaining security while enabling characteristic determination.
Solution Approach 2:
The mapping configuration acts as an intermediary mechanism that bridges the gap between encrypted traffic and network control functions. Instead of directly analyzing encrypted traffic, the network uses the pre-configured mapping to obtain CCA information, which mediates between security requirements and traffic characterization needs.
2Measurement precision
If deep packet inspection is used to analyze encrypted traffic, then data traffic characteristics can be obtained, but processing complexity and computational resources increase
Solution Approach 1:
The invention extracts only the necessary CCA information from the data traffic through the pre-configured mapping, rather than performing comprehensive deep packet inspection on the entire encrypted traffic stream. This extraction approach obtains the required characteristics while avoiding the computational burden of analyzing all traffic details.
Solution Approach 2:
Instead of directly inspecting the actual encrypted traffic, the system uses a copy or representation of traffic characteristics through the mapping configuration. The mapping provides a simplified representation that contains the essential CCA information without requiring complex analysis of the original traffic.
3Productivity
If traffic handling actions are optimized based on CCA information, then QoE and QoS are improved, but the system requires additional configuration and control mechanisms
Solution Approach 1:
The mapping configuration serves multiple functions: it identifies data traffic, provides CCA information, and enables optimized handling actions. This universal mechanism consolidates what would otherwise require separate configuration systems, reducing overall complexity while enabling sophisticated traffic optimization.
Solution Approach 2:
The data traffic sender performs self-service by automatically configuring and providing the mapping to the core network domain. This eliminates the need for manual network configuration and reduces the burden on network operators, allowing the system to achieve optimized handling with minimal external intervention.

AI summary
A technique for handling data traffic in a core network domain of a communication network is described. An apparatus comprised by the technique is configured to be located in the core network domain and to receive data traffic sent under control of a transport layer protocol that is configured to apply a congestion control algorithm, CCA. The apparatus is further configured to analyze the data traffic to obtain a data traffic analyzation result, to obtain, based on the analyzation result, CCA information about the CCA that can be or is applied by the transport layer protocol, and to perform a traffic handling action for the data traffic taking into account the obtained CCA information.
