Diameter Overload Scope via Destination-Host Alias
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining and conveying network load information in Diameter-based telecommunications networks is challenging, as existing methods require monitoring devices and taps on physical links, and there is difficulty in conveying load information to other nodes in a usable form for decision-making.
Innovation Solution
Implementing Destination-Host defined overload scope, where a Diameter node identifies sessions as part of an overload group, specifies an alias for overload messages, and includes this alias in messages associated with group members to manage overload conditions without affecting non-overloaded nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If monitoring devices and taps are attached to physical links to determine network load, then load information can be obtained, but device complexity and difficulty of implementation increase
Solution Approach 1:
The patent enables network nodes to self-report their load conditions through Diameter overload control messages. Each node monitors its own load and autonomously generates overload indications when thresholds are exceeded, eliminating the need for external monitoring devices and physical taps on network links.
2Reliability
If load information is conveyed to all nodes in the network, then comprehensive overload management is achieved, but information loss and communication overhead increase
Solution Approach 1:
The patent implements scope parameters that restrict overload information to specific destinations, services, or network segments. This allows load information to be selectively conveyed only to nodes that need to act on it, rather than broadcasting to all nodes, thereby reducing communication overhead and information loss.
3Measurement precision
If detailed network topology information is included in overload messages, then precise overload control is achieved, but security and privacy concerns increase
Solution Approach 1:
The patent introduces alias parameters as intermediaries that mask the actual network topology. Instead of including real node identities and detailed topology information in overload messages, the system uses alias identifiers that preserve the functional ability to route and control traffic while hiding sensitive network structure information.
4Productivity
If overload control actions are applied network-wide, then overall network performance is improved, but non-overloaded nodes are unnecessarily impacted
Solution Approach 1:
The patent implements scope parameters that allow overload control actions to be applied locally to specific destinations, services, or network segments rather than network-wide. This enables non-overloaded nodes and services to continue operating normally without being affected by overload conditions in other parts of the network.

AI summary
Methods, systems, and computer readable media for Destination-Host defined overload scope are disclosed. According to one aspect, a method for Destination-Host defined overload scope includes, at an entity for processing Diameter signaling messages: identifying at least one Diameter session as a member of an overload group; specifying an alias for use to identify the entity for processing Diameter signaling messages as a destination of Diameter messages; associating the specified alias with the overload group; and including the specified alias in messages associated with members of the overload group.
