Network Path Probing With IP-Label Associations to Reduce Overhead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud networking technologies face high system overhead, low transmission quality, and low transmission efficiency due to the lack of control over intermediate transit network nodes, particularly in tunneling technologies like IPsec, GRE, VxLAN, and MPLS, which do not effectively manage resource sharing and interoperability.
Innovation Solution
A path probe method and device that establish associations between link information and path labels using IP addresses to optimize network paths, reducing system overhead and enabling efficient resource sharing across operators and service providers through an IP overlay mechanism based on label switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tunneling technology (IPsec, GRE, VxLAN, MPLS) is used for cloud networking, then network path establishment is enabled, but system overhead increases and transmission efficiency decreases
Solution Approach 1:
The patent introduces path probe packets as intermediary elements that carry both IP address information and link information. These packets act as mediators between the control plane and data plane, enabling efficient path discovery and association establishment without requiring complex tunneling protocols, thus improving transmission efficiency while maintaining reliable path establishment.
Solution Approach 2:
The patent segments the path establishment process into distinct phases: path probe packet transmission, association relationship establishment, and data packet forwarding. By dividing the overall process into manageable segments with specific functions, the system achieves efficient path management without the overhead of monolithic tunneling protocols.
2Adaptability or versatility
If tunneling technology is deployed for resource sharing, then network connectivity is achieved, but resource sharing efficiency and interoperability are reduced
Solution Approach 1:
The patent creates a universal path management mechanism that works across different network types and service providers. The association relationship between IP addresses and link information provides a common framework that enables resource sharing and interoperability without being constrained by specific tunneling technologies, achieving both versatility and efficiency.
3Ease of operation
If traditional path probe methods are used, then path discovery is possible, but system overhead is high due to lack of control over intermediate nodes
Solution Approach 1:
The patent implements a feedback mechanism where path probe packets traverse the network path and return with information about intermediate nodes. This feedback allows the source node to establish accurate associations between IP addresses and link information, enabling path discovery with controlled overhead and full visibility into network conditions.

AI summary
This present disclosure describes path probe methods and devices. The methods comprise receiving a first path probe packet; establishing a first association according to link information in the first path probe request packet and a path label of a network path to be probed; determining a third association based on an IP address in the first path probe packet and the path label of the network path to be probed. The IP address includes an IP address of an adjacent network node of the first network node, and a third association includes an association of the path label with the IP address of the adjacent node. The path probe method may reduce system overhead. In the transmission process, the number of network nodes may also be set according to needs. An IP overlay network based on label switching is realized.
