Adaptive Resource Reservation for End-to-End Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ICT systems face excessive and random end-to-end latency due to signal propagation, processing delays, layered protocol redundancies, asynchronous operations, and varying link conditions, which hinder performance in latency-sensitive applications like data centers, interactive internet applications, and 5G networks.
Innovation Solution
The adaptive resource reservation and end-to-end tunneling technique minimizes latency by reserving physical resources at intermediate routers and switches, reducing processing delays and protocol overhead, and establishing a direct communication tunnel through coordinated resource allocation and synchronization, allowing data to propagate with minimal latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If layered communication protocols (TCP/IP stack) are used for reliable data transport, then communication reliability is improved, but end-to-end latency increases due to processing delays at each protocol layer
Solution Approach 1:
The patent extracts and removes protocol headers and processing overhead from the data transmission path by implementing a tunneling mechanism. Data packets are encapsulated in a simplified format that bypasses intermediate protocol processing steps, effectively taking out the redundant protocol layers that cause latency while maintaining reliability through selective acknowledgment mechanisms.
Solution Approach 2:
The patent establishes resource reservations and pre-configures transmission paths before actual data transfer begins. By pre-negotiating bandwidth allocation, buffer reservations, and route optimization in advance, the system eliminates runtime protocol negotiation and dynamic resource allocation delays, achieving low-latency transmission while maintaining reliability through pre-established error correction and retransmission protocols.
2Adaptability or versatility
If data packets are processed and forwarded through multiple intermediate switches and routers, then network connectivity and adaptability are improved, but end-to-end latency increases due to repeated processing and buffering
Solution Approach 1:
The patent merges multiple intermediate processing functions into a single end-to-end tunnel connection. By combining routing, switching, and protocol processing into a pre-established direct path, the system eliminates repeated handling at each intermediate node while maintaining network adaptability through dynamic tunnel establishment and resource reservation mechanisms that can adapt to changing network conditions.
3Productivity
If resource sharing among multiple communication nodes is allowed, then network utilization and efficiency are improved, but latency becomes random and unpredictable due to competition for resources
Solution Approach 1:
The patent implements resource reservation mechanisms that pre-allocate network resources to specific communication flows before transmission begins. By reserving bandwidth, buffer space, and processing capacity in advance, the system guarantees deterministic latency bounds while maintaining high overall network utilization through efficient resource allocation and release protocols that allow resources to be dynamically assigned to different flows based on demand.
Data Source
AI summary
An adaptive method for sending data over a communications path from a source node to a destination node through a communications tunnel, the communications path comprising the source node, the destination node, and at least one intermediate node. The steps include initiating a communications session; determining a communication path for establishing the communications tunnel from the source node to the destination node, the path comprising one or more intermediate nodes; synchronizing the nodes; measuring the channel conditions of each of the communication segments between nodes to determine at least one channel transmission parameter; selecting a transmission scheme dependent on the channel parameter(s); reserving resources at the intermediate node(s) and destination node in sequential time slots such that resources at a node are reserved during the time slot in which the data is expected to arrive; and transmitting data through the communications tunnel using the selected transmission scheme.
