Abstract

Techniques for monitoring data transport in a network virtualization function chain (chain). A path tracing packet is generated having a Midpoint Compressed Data (MCD) to collect path tracing information of the chain. The network virtualization function node is configured to record an MCD containing Wide Local Path Tracing Identification (WL PT ID). The WL PT ID includes a first field having a value that indicates that a non-standard path tracing format is to be used and a second field that indicates a particular path tracing format to be used. The path tracing packet is passed through the chain and is received back after passing through the chain. Data collected by the path tracing packet is then analyzed to determine which network virtualization function nodes and chains the path tracing packet passed through and the amount of time taken for the path tracing packet to pass through the chain.
