Multipath Aggregation Scheduling for Network Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipath transmission protocols, such as MPTCP, do not effectively increase data transmission rates or fully utilize communication resources across multiple paths, leading to inefficiencies in data congestion management.
Innovation Solution
A multipath aggregation scheduling method where a client allocates network packets to different paths in specific orders, allowing packets sent later on one path to be sent first on another path, thereby increasing the transmission rate and improving average transmission rates statistically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple paths are used for data transmission, then transmission robustness is improved and congestion probability is reduced, but data transmission rate is not increased and path resources are not fully utilized
Solution Approach 1:
The patent implements dynamic packet scheduling by adjusting the sending order of network packets on different paths based on real-time path conditions. The protocol stack dynamically determines which packets to send on which paths and in what order, allowing the system to adapt to changing network conditions and fully utilize available path resources, thereby resolving the contradiction between reliability and transmission rate.
Solution Approach 2:
The patent applies preliminary action by pre-arranging the sending order of packets on multiple paths before actual transmission. The protocol stack determines and establishes the packet sending sequence in advance, allowing packets that would otherwise be sent later to be transmitted first on alternative paths, thus proactively improving transmission rate while maintaining reliability.
2Device complexity
If packets are sent in sequential order on each path, then protocol simplicity is maintained, but transmission rate is limited due to congestion on individual paths
Solution Approach 1:
The patent segments the packet transmission process by dividing packets into different groups and assigning them to different paths with different sending orders. Instead of treating all packets uniformly, the protocol stack segments them based on their characteristics and path conditions, allowing parallel optimization of multiple packet streams without significantly increasing overall protocol complexity.
Solution Approach 2:
The patent introduces dynamic packet scheduling that adjusts sending orders on different paths based on real-time conditions. This dynamic approach allows the system to optimize transmission rate adaptively while maintaining a relatively simple protocol structure, as the complexity is managed through intelligent scheduling algorithms rather than complex protocol mechanisms.

AI summary
A multipath aggregation scheduling method and an electronic device provide for configuring transmission sequences of network packets on different paths when there are a plurality of paths between a client and a service end. This enables a network packet sent later on any of the plurality of paths to be sent first on at least one other path, thereby increasing transmission rate of the network.
