Graphical Packet Flow Visualization for Network Device Troubleshooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for tracking packet operations within network devices are inefficient, requiring users to sift through numerous logging messages to understand the operations performed on a packet, as current logs and debugs apply to entire features or protocols rather than individual packets, making it time-consuming to determine specific packet operations.
Innovation Solution
A graphical interface is developed to display packet progression through various phases such as routing, network address translation, and access control, with animated visuals and dynamic linking to corresponding rules, allowing users to visualize and interact with packet operations, including generating reverse rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional logging messages are used to track packet operations, then comprehensive operation records are obtained, but the time required to understand packet operations increases significantly
Solution Approach 1:
The patent creates a graphical copy or representation of the packet's journey through the network device. Instead of examining raw logging messages, users see a visual replica of the packet flow path, phases, and operations performed. This graphical copy consolidates information from multiple log sources into a single intuitive view, dramatically reducing analysis time while preserving complete operation information.
Solution Approach 2:
The patent introduces an intermediary graphical interface between the user and the complex logging system. This intermediary layer translates raw log data into visual representations of packet phases and operations. The intermediary automatically correlates logs with specific packets and presents them in a structured graphical format, eliminating the manual correlation process and reducing time loss.
2Loss of information
If detailed logging messages are examined to understand packet operations, then complete operation details are obtained, but the complexity of analysis increases
Solution Approach 1:
The patent segments the packet processing journey into distinct phases (ingress, routing, NAT, security, egress, etc.), with each phase visually represented separately in the graphical interface. This segmentation allows users to understand complex operations by examining individual phases rather than trying to parse through undifferentiated logging messages, reducing analytical complexity while maintaining complete operational detail.
Solution Approach 2:
The patent uses color coding to differentiate various packet phases, operations, and outcomes in the graphical representation. Different colors indicate different phase types, success/failure states, and operation categories. This visual encoding system reduces complexity by allowing users to quickly grasp operational details through color patterns rather than text-heavy logs.
3Loss of information
If conventional logs are used to track individual packets, then operation data is captured, but the effort to correlate logs with specific packets increases
Solution Approach 1:
The patent creates a graphical copy of the individual packet's journey that is directly linked to the corresponding log data. Each visual element in the graphical representation corresponds to specific log entries, allowing users to see the connection without manual correlation. The system automatically associates packet identifiers and correlates all relevant logs with the specific packet being analyzed.
Solution Approach 2:
The patent implements feedback mechanisms where selecting or hovering over elements in the graphical representation automatically retrieves and displays related log information. This feedback loop provides immediate correlation between visual packet phase representations and their corresponding log entries, eliminating the manual effort of cross-referencing while ensuring complete individual packet operation data is captured and accessible.
