Hardware accelerated path tracing analytics

A system comprising:

• one or more processors;
• and
• one or more computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, at a network controller associated with a network, first telemetry data from nodes in the network;
• storing, in a lookup table and based at least in part on the first telemetry data, an indication of whether an individual node of the nodes comprises the specific capability in association with an identifier associated with the individual node;
• receiving, at the network controller, a probe packet that has been sent through the network from a first node to a second node;
• determining, based at least in part on the lookup table, whether the first node comprises the specific capability;
• at least one of:
• based at least in part on determining that the first node does not comprise the specific capability, determining a full timestamp associated with the first node based at least in part on a first full timestamp included in a first header of the probe packet, wherein the first header is at a first depth in the probe packet;
• or
• based at least in part on determining that the first node comprises the specific capability, determining the full timestamp associated with the first node based at least in part on appending a first portion of a second full timestamp included in a second header of the probe packet to a second portion of the first full timestamp, wherein the second header is at a second depth in the probe packet that is shallower than the first;
• and
• storing, by the network controller and in the database associated with the network, the full timestamp in association with the first node.

One or more non-transitory computer-readable media storing instructions executable by one or more processors that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:

• receiving, at a network controller associated with a network, first telemetry data from nodes in the network;
• storing, in a lookup table and based at least in part on the first telemetry data, an indication of whether an individual node of the nodes comprises the specific capability in association with an identifier associated with the individual node;
• receiving, at the network controller, a probe packet that has been sent through the network from a first node to a second node;
• determining, based at least in part on the lookup table, whether the first node comprises the specific capability;
• at least one of:
• based at least in part on determining that the first node does not comprise the specific capability, determining a full timestamp associated with the first node based at least in part on a first full timestamp included in a first header of the probe packet, wherein the first header is at a first depth in the probe packet;
• or
• based at least in part on determining that the first node comprises the specific capability, determining the full timestamp associated with the first node based at least in part on appending a first portion of a second full timestamp included in a second header of the probe packet to a second portion of the first full timestamp, wherein the second header is at a second depth in the probe packet that is shallower than the first;
• and
• storing, by the network controller and in the database associated with the network, the full timestamp in association with the first node.
