Radiolet Network Architecture for Mobile Data Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile data networks face inefficiencies due to high latencies and resource misallocation caused by the 'Mobile Middle Mile' problem, where data traverses multiple switching offices before reaching the subscriber, and lack of end-to-end intelligence between applications and networks, leading to over-provisioning of resources.
Innovation Solution
Implementing a system with 'radiolets' that bring application and content servers closer to subscribers, enabling intelligent cross-layer resource management and flow control, which separates control and data planes, allowing for optimized traffic routing without modifying existing networks or datacenters, and providing network and application awareness to reduce latency and improve resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data traverses multiple switching offices (local, regional, central) to reach the subscriber, then network mobility management and session management are maintained, but latency increases and resource efficiency deteriorates
Solution Approach 1:
The patent segments the network path by introducing intermediate content distribution points between the central switching office and the subscriber. Data is divided into segments that can be cached and delivered from locations closer to the subscriber, reducing the distance traversed while maintaining the hierarchical switching structure for mobility management.
Solution Approach 2:
The patent introduces intermediary content distribution points and caches at intermediate switching offices. These intermediaries hold copies of popular content locally, allowing data to be delivered from a nearby location rather than traversing the entire path to the central switching office and back, thus reducing latency while preserving network control structures.
2Device complexity
If applications are delivered from centralized datacenters, then resource pooling and management are simplified, but the distance data must travel increases, creating inefficiency
Solution Approach 1:
The patent implements local quality by placing content distribution points and caches at multiple locations throughout the network infrastructure (at switching offices and intermediate points). This allows content to be delivered from the nearest available cache rather than always from the centralized datacenter, reducing path length while maintaining centralized resource management capabilities.
Solution Approach 2:
The patent applies preliminary action by pre-caching popular content at intermediate switching offices and content distribution points before actual user requests arrive. This anticipatory caching reduces the distance data must travel when users request content, as copies are already positioned closer to potential subscribers.
3Loss of time
If network operators upgrade existing networks to reduce latency, then service quality improves, but capital expenditure and operational costs increase significantly
Solution Approach 1:
The patent uses copying by creating distributed cache copies of content at intermediate network points rather than requiring physical infrastructure upgrades. These software-based copies enable faster local delivery without the capital expenditure associated with building new datacenters or upgrading core network hardware, reducing latency through intelligent data replication.
Solution Approach 2:
The patent employs temporary, software-based cache instances at switching offices that can be dynamically created and removed as needed. These lightweight, virtual cache objects provide latency reduction benefits without requiring permanent, expensive hardware infrastructure, allowing operators to optimize performance on-demand rather than investing in permanent upgrades.
4Adaptability or versatility
If applications treat the network as a blackbox, then application portability is maintained, but application awareness of network conditions is lost, leading to over-provisioning
Solution Approach 1:
The patent implements feedback mechanisms that provide network state information (such as latency, bandwidth availability, and content location) back to applications. This feedback loop enables applications to adapt their behavior based on actual network conditions, optimizing resource usage without sacrificing portability, as the feedback is provided through standardized interfaces that work across different network environments.

AI summary
An exemplary system according to the present disclosure comprises a lower tier radiolet™ that is in communication with a local switching office of a mobile data network, and an upper tier radiolet™ that is in communication with the lower tier radiolet™ and an Internet datacenter. In operation, the upper tier radiolet™ receives data extracted from the Internet datacenter and distributes at least a portion of the received data to the lower tier radiolet™. At the lower tier radiolet™, the portion of received data is stored. The lower tier radiolet™ then receives a data request (relating to a portion of received data) and in turn, transmits data from the portion of received data to a source of the data request. The lower tier radiolet™ is located closer to the source of the data request than the Internet datacenter to improve application performance and efficiency of network as well as datacenter.
