Distributed Gateway Functionality for Network Traffic Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data communication systems face heavy load issues due to all data traffic from and to terminals needing to travel through a single gateway device, leading to potential bottlenecks and inefficiencies.
Innovation Solution
Distributing the functionality of the gateway device across multiple data communication devices within the network, allowing data traffic to be directed to the starting points of logical tunnels without relying on a single point, using control data to establish and manage these tunnels based on terminal mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all data traffic from and to terminals travels through a single gateway device, then centralized control and management is simplified, but network load concentration causes bottlenecks and reduced efficiency
Solution Approach 1:
The patent segments the gateway device functionality by distributing it across multiple data communication devices in the network. Each device can independently perform gateway functions such as establishing and removing logical data communication tunnels based on terminal mobility, thereby eliminating the single-point bottleneck while maintaining distributed control capabilities
2Productivity
If gateway functionality is distributed across multiple devices, then network load is balanced and efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements universality by enabling multiple data communication devices to perform identical gateway functions. Each device can establish and remove logical tunnels, forward data frames, and manage terminal connectivity independently, allowing the system to scale without proportionally increasing complexity
3Loss of energy
If communication-session-specific optimization routes are maintained for long periods, then route reuse reduces signaling traffic, but a huge mess of routes accumulates requiring heavy maintenance
Solution Approach 1:
The patent applies dynamics by making the route optimization lifetime adjustable and context-dependent. The system can dynamically adapt the duration for which optimization routes are maintained based on terminal mobility patterns and network conditions, balancing route reuse benefits against maintenance complexity

AI summary
In a data communication system according to the invention the functionality of the gateway device is distributed in a data communication network thereby reducing the need to direct the data traffic from and to terminals (212, 213, 214) through a single point in the data communication network. A first data communication device (207) is arranged to make, through signalling, second data communication devices (204, 205, 206) capable of directing the data communications of the terminals to the starting points of the respective logical data communication tunnels (215, 216, 217). This way there is no need for all logical data communication tunnels to start from, or depending on the direction, to end at, the same point in the data communication network.
