Title:
TROUBLESHOOTING MULTI-LAYERED NETWORKS USING DATA PATH ANALYSIS
Document Type and Number:
Japanese Patent JP2021036724
Kind Code:
A
Abstract:
To provide techniques for improving network routing.SOLUTION: Techniques and supporting systems implement a recursive routing mechanism in hierarchical topological addressed environments to analyze and determine the presence of packet-forwarding errors within an IP network comprising a plurality of network-connected devices. This includes: receiving, at a software defined network device, an indication of a potential packet-forwarding error between first and second devices of the plurality of network-connected devices; and injecting, by the software defined network device, a test packet at an ingress to the first device. The test packet includes an initial ingress interface location identifying the first device, an alternate ingress interface location identifying the software defined network device, and an egress interface location identifying the second device.SELECTED DRAWING: Figure 4
