A network device may receive a packet and may determine whether a next header of the packet is an Internet protocol (IP) header, an Internet control message protocol (ICMP) header, or a segment routing header. The network device may determine, when the next header of the packet is the IP header, whether policy processing of the packet is set to ultimate segment decapsulation and may discard the packet when the policy processing of the packet is not set to ultimate segment decapsulation. The network device may decapsulate an outer header of the packet when the policy processing of the packet is set to ultimate segment decapsulation and may process the packet after decapsulating the outer header of the packet, to generate a processed packet. The network device may forward the processed packet toward a destination.

Processing segment routing packets with two policy processing instructions in a segment routing domain

Techniques are described for provisioning non-colored segment routing label switched paths (LSPs) via segment routing policies in border gateway protocol (BGP). For example, an ingress router receives a segment routing policy advertisement specifying an endpoint of one or more paths, and a policy color field of the one or more paths, wherein the policy color field is specified with a designated value that causes the network device to store the one or more paths in a data structure that stores non-colored paths. The ingress router determines that the policy color is specified with the designated value. The ingress router, in response to determining that the policy color is specified with the designated value, stores the one or more paths in the data structure that stores non-colored paths.

Provisioning non-colored segment routing label switched paths via segment routing policies in border gateway protocol

A system includes a cylinder, a piston, a sensor configured to detect vibrations of the cylinder, piston, or both that correspond with varying pressures within the cylinder, and a controller coupled to the sensor. The controller is configured to receive a first signal from the sensor corresponding with first vibrations of the cylinder and to deduce from the first signal a first operating value of a parameter indicative of peak firing pressure at a first time, to compare the first operating value with a baseline value of the parameter indicative of peak firing pressure to detect a change in peak firing pressure, to receive a second signal from the sensor corresponding with second vibrations of the cylinder and to deduce from the second signal a second operating value of the parameter indicative of peak firing pressure at a second time, and to compare the second operating value with the baseline value to confirm the change in peak firing pressure.

A system includes a reciprocating engine having a piston disposed in a cylinder, an intake valve, an exhaust valve, and an exhaust flow path downstream of the exhaust valve. The system also includes a first sensor configured to obtain a first feedback indicative of an exhaust gas parameter in the exhaust flow path. The system also includes a controller configured to identify a valve wear condition of at least one of the intake valve or the exhaust valve at least partially based on the first feedback from the first sensor.

System and method of valve wear detection

The present disclosure includes systems and methods for monitoring a prechamber of an engine. In one embodiment, a system includes a combustion engine having a combustion chamber and a prechamber, where the prechamber is configured to direct a flame toward the combustion chamber, a fuel supply valve configured to adjust a flow of a fuel toward the prechamber, a prechamber valve configured to receive the fuel into the prechamber, a knock sensor coupled to the combustion engine, and a controller. The controller is configured to control operations of the combustion engine, to receive a signal from the knock sensor, to determine a combustion parameter based at least on the signal, to determine a condition of one or both of the prechamber and the prechamber valve based at least on the combustion parameter, and to adjust the fuel supply valve based at least on the condition.
