Claim 7:
8. A system for routing Internet Protocol Security data packets, the system comprising:
one or more processors; and
one or more non-transitory 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 function virtualization (NFV) node, a path tracing packet having a Midpoint Compressed Data (MCD) stack to collect path tracing information from nodes of an NFV chain, the NFV node being configured to include its MCD in the MCD stack of the path tracing packet, wherein the MCD of the NFV node contains a Wide Local Path Tracing Identification (WL PT ID);
passing the path tracing packet through the NFV chain;
using the path tracing packet to collect the path tracing information from nodes of the NFV chain; and
analyzing the path tracing information to determine which of the nodes the path tracing packet passed through and an amount of time taken for the path tracing packet to pass through the NFV chain.
