Latest Patents

The provided information lists one patent for Kim: “Method for High Speed Rerouting in Multi Protocol Label Switching Network.” The invention describes a way to reduce packet loss and rapidly reroute traffic, particularly to protect and recover multipoint-to-point Label Switched Paths (LSPs).

The method uses a backup LSP comprising an Explicitly Routed LSP with a reverse tree of the protected multipoint-to-point LSP. When a node or link failure occurs, traffic is directed in the reverse direction through the backup path, from an egress Label Switching Router toward an ingress router. This approach is intended to support fast recovery across the network.
