Diameter Overload Broker for Non-Adjacent Node Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Diameter overload control mechanisms fail to effectively collect and distribute overload information to non-adjacent nodes, especially when intervening nodes do not support or cannot be trusted, leading to 'islands' of reporting domains and potential identity exposure.
Innovation Solution
A Diameter overload control information broker system that collects and distributes overload information from and to non-adjacent nodes, acting as a hub to aggregate and relay information, using mechanisms like query-response or pub-sub interfaces, and ensuring trusted distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Diameter overload control information is distributed using existing mechanisms, then adjacent nodes can receive overload information, but non-adjacent nodes cannot receive the information due to intervening nodes that do not support or cannot be trusted
Solution Approach 1:
The patent introduces a Diameter overload control information broker as an intermediary component that collects overload control information from multiple Diameter nodes and distributes it to non-adjacent nodes. The broker acts as a trusted mediator that overcomes the limitations of existing direct distribution mechanisms, enabling information to reach nodes that are not adjacent while maintaining security and reliability through the broker's mediation.
2Loss of information
If individual node overload information is reported directly, then specific node identity is preserved, but node identity exposure creates security risks when intervening nodes are untrusted
Solution Approach 1:
The broker serves as a trusted intermediary that collects overload control information from reporting nodes and redistributes it to receiving nodes without exposing the identity of the original reporting nodes. This mediation mechanism preserves the accuracy of overload control information while protecting node identities from untrusted intervening nodes, thereby eliminating the security risk of identity exposure.
3Ease of operation
If Diameter nodes support overload control information natively, then information can be communicated directly, but nodes that do not support it create islands of reporting domains
Solution Approach 1:
The broker implements a universal mechanism that handles overload control information distribution for both nodes that support native overload control and those that do not. By serving as a centralized information distribution point, the broker eliminates the fragmentation caused by unsupported nodes, allowing seamless communication across the entire network regardless of individual node capabilities.

AI summary
Methods, systems, and computer readable media for collecting and distributing Diameter overload control information to non-adjacent nodes are disclosed. One system for implementing the subject matter described herein includes a Diameter overload control information broker. The Diameter overload control information broker includes a Diameter overload control information collector for receiving Diameter overload control information from at least one Diameter node separate from the Diameter overload control information broker. The broker includes a memory for storing the overload control information. The broker further includes a Diameter overload control information distributor for distributing the Diameter overload control information to at least one Diameter node that is not adjacent to the at least one Diameter node from which the overload control information was received.
