Abstract: The present disclosure relates to apparatus and methods for route invalidation. In one example method, a common ancestor node of a network determines switching of a parent node of a node based on an update message received from the node using a new routing path established based on the switching of the parent node. The common ancestor node generates a No-Path message based on the update message. The No-Path message is for invalidating a previous routing path associated with the node on the switching of the parent node. The update message comprises at least one bit authorizing generation of the No-Path message by the common ancestor node. The at least one bit is placed in a transit information option in the update message.

Abstract: A data processing method includes receiving, by an operating system of a device, a start instruction from an application in the device that includes an identifier of a socket connection, where the application is a latency-insensitive application, calling, by the operating system according to the start instruction, a monitoring system in the operating system to monitor buffering of data of the socket connection in a kernel buffer, where the data of the socket connection is from an underlying protocol stack, and generating, by the monitoring system, a data readable identifier when a time interval between a current moment and a start moment is greater than or equal to a timeout duration, where the start moment is when the operating system receives the start instruction, and the data readable identifier indicates that the data of the socket connection is readable by the application.

Abstract: Example apparatus and methods for optimized route invalidation using modified no-path Destination Oriented Directed Acyclic Graph Advertisement Object (DAO) signaling are disclosed. In one example method, a node switching its current parent is adapted to send a regular DAO message. Using the changed signaling, a common ancestor node generates a No-Path destination oriented directed acyclic graph advertisement object message (NPDAO) on behalf of the switching node on receiving a refreshed DAO from an alternate path. The common ancestor node reuses a same Path Sequence from the regular DAO based on which the NPDAO gets generated. The common ancestor node detects routing anomaly using next hop mismatch on reception of the DAO to generate the NPDAO on behalf of the target node. The No-Path DAO traverses downward/downstream along the previous path.
