Packet Marking for Deadline-Aware Flow Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data networks face challenges in effectively managing network flows, particularly in ensuring timely delivery of deadline-aware traffic, as existing technologies lack efficient mechanisms to prioritize and manage packets based on deadlines, leading to potential delays and bandwidth inefficiencies.
Innovation Solution
The implementation of packet marking techniques in network devices, which classify and mark packets as deadline-aware or background flows, allowing for proactive management actions such as throttling or prioritization, to ensure timely delivery of critical traffic and optimize network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet marking techniques are implemented to classify and mark packets as deadline-aware or background flows, then timely delivery of critical traffic is ensured and network resources are optimized, but device complexity increases
Solution Approach 1:
The patent segments network traffic into different classes (deadline-aware flows and background flows) based on packet characteristics and deadline information. This segmentation allows the system to apply different handling policies to different traffic types, ensuring timely delivery for critical traffic while managing overall device complexity through structured classification.
Solution Approach 2:
The patent performs preliminary actions by marking packets with deadline information before they enter the network device. This advance classification and marking enables the device to prepare appropriate handling actions in advance, reducing real-time processing complexity while ensuring timely delivery of critical traffic.
2Productivity
If packet marking techniques are implemented to prioritize critical packets and throttle non-essential traffic, then network flow management is enhanced and bandwidth usage is optimized, but processing time increases
Solution Approach 1:
The patent applies preliminary action by pre-marking packets with deadline and priority information before they reach the network device. This advance preparation eliminates the need for complex real-time analysis, reducing processing time while enabling efficient bandwidth management through pre-established classification rules.
Solution Approach 2:
The patent implements feedback mechanisms where network devices monitor traffic patterns and adjust marking decisions based on observed behavior. This feedback loop optimizes bandwidth usage by learning from actual traffic conditions while maintaining fast processing through automated adaptive decisions.
3Reliability
If deadline aware flow management is implemented, then network performance is improved and timing requirements are met, but measurement precision requirements increase
Solution Approach 1:
The patent performs preliminary measurement and classification of traffic characteristics before packets enter the network device. By pre-determining deadline information and traffic patterns, the system reduces the precision requirements for real-time measurements while still meeting timing requirements through advance preparation and structured classification.

AI summary
Network devices facilitate flow management through packet marking. The network devices may be switches, routers, bridges, hubs, or any other network device. The packet marking may include analyzing received packets to determine when the received packets meet a marking criterion, and then applying a configurable marking function to mark the packets in a particular way. The marking capability may facilitate deadline aware end-to-end flow management, as one specific example. More generally, the marking capability may facilitate traffic management actions such as visibility actions and flow management actions.
