Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data center networks face bottlenecks in inter-node communication bandwidth and overhead, limiting system performance and application design.
Innovation Solution
An integrated circuit device with multiple data processing units connected via high-speed inter-unit data links, where incoming data is repackaged into multiple data packets and metadata is generated for routing, allowing data to be transmitted and processed efficiently across nodes without significant processing overhead, enabling improved switching speeds and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If data is transmitted through single-node network switches, then processing overhead is reduced, but inter-node communication bandwidth is limited
Solution Approach 1:
The network switch is divided into multiple independent data processing units (first data processing unit, second data processing unit, etc.), each capable of independently receiving, processing, and forwarding data. This segmentation allows parallel data handling across multiple nodes, thereby increasing the aggregate inter-node communication bandwidth without requiring a single overly complex switch architecture.
Solution Approach 2:
The patent transitions from a single-node switch architecture to a multi-node distributed architecture, adding the dimension of spatial distribution. Multiple data processing units are connected through inter-unit data links, enabling data to be processed and forwarded simultaneously across different physical locations, thus scaling up bandwidth capacity.
2Power
If multiple data processing units are used to increase bandwidth, then inter-node communication capacity improves, but processing overhead increases
Solution Approach 1:
The ingress management module performs preliminary actions by storing incoming data and generating metadata before data is forwarded to multiple output ports. This pre-processing consolidates the work that would otherwise need to be done at each output port, reducing the processing overhead at subsequent stages while maintaining high communication capacity.
Solution Approach 2:
The ingress management module acts as an intermediary between the input ports and the multiple output ports. It receives data from input ports, stores it temporarily, generates metadata, and then distributes it to multiple output ports. This intermediary function centralizes the processing workload, preventing redundant processing at each output port and thereby reducing overall processing overhead.
3Speed
If data is repackaged into multiple packets for high-speed transmission, then transmission speed improves, but data routing complexity increases
Solution Approach 1:
The ingress management module performs preliminary action by generating metadata associated with data packets before they are forwarded through the network. This metadata contains routing information that simplifies the forwarding process at intermediate nodes, as they only need to look up the pre-computed metadata rather than performing complex routing decisions, thus enabling high-speed transmission without proportionally increasing routing complexity.
