Abstract: Technologies and techniques for verifying the operational readiness of an automated driving vehicle before initiating a drive is disclosed. The method involves performing a predefined set of automated checks each time the vehicle is started. These checks are executed using predefined combinations of the vehicle's sensor system and actuator system. Additionally, the method includes verifying that cyclic checks conducted under predefined conditions in the past were completed successfully with sufficient frequency. The drive is enabled if both the startup checks and the past cyclic checks meet the required criteria. Aspects of the present disclosure also pertains to the automated driving vehicle itself.

Abstract: Technologies and techniques for expanding an information cluster of a trajectory class. A trajectory is taken for a vehicle and a location-specific characteristic of the vehicle is acquired, and/or a vehicle-specific characteristic of the vehicle is acquired when taking the trajectory. The location-specific characteristic of the vehicle is provided and/or the vehicle-specific characteristic of the vehicle is provided. Additional steps include generating an actual trajectory by assigning the location-specific characteristic and/or the vehicle-specific characteristic to the taken trajectory, and comparing the actual trajectory with a comparison trajectory. The actual trajectory is assigned to one of two different trajectory classes depending on the comparison, such that the trajectory class into which the actual trajectory is classified is expanded in relation to its information cluster.

An apparatus for maintaining protocol adjacency state with a forwarding failure is also disclosed.

Abstract: A technique efficiently avoids transient routing disturbances in link state routing protocols with fragmented link state packets (LSPs) in a computer network. According to the novel technique, a link state router (LSR) specifies which of two or more links are to be advertised in each of two or more corresponding LSP fragments. The LSR advertises the states of the specified links in the corresponding LSP fragments to one or more other LSRs. In other words, each link of the LSR is assigned to a particular LSP fragment, and the state of the link is always to be advertised in that particular LSP fragment (i.e., no fragment wrapping). Upon receiving the LSP fragments, the other LSRs may update the correct link states based on the individual LSP fragments, i.e., without transient routing disturbances caused by fragment wrapping.

Abstract: A networking device such as a router may include, in one embodiment, a database storing a plurality of link state entries, and a cache operatively coupled with the database, the cache storing entries relating to the link state entries of the database. The networking device may also include a module for sending, over a network, packets including link state data, the module operatively coupled with the cache. In one example, the module accesses the cache to create one or more packets including link state data. Embodiments of the invention may be used for forming CSNP packets (complete sequence number packets) without the need for having to repeatedly walking a link state database in order to form the CNSP packets.

Abstract: A system and method for bidirectional forwarding detection (BFD) rate-limiting and automatic BFD session activation includes tracking a total bidirectional forwarding detection (BFD) packet rate for a line card (LC) of the node, and rejecting operations associated with creation of a new BFD session that would cause the total BFD packet rate to exceed a predetermined maximum rate. The new BFD session is stored in a state on the node and the operations of the new BFD session are automatically retried at a time when doing so would not exceed the predetermined maximum rate. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
