This read-only DisplayString is the name of this underlying Path, typically describing the local and remote WAN Link combination it represents. An admin reads this to know at a glance which specific link pairing (for example "MPLS-to-MPLS" or "Broadband-to-LTE") the accompanying loss, latency, and drop statistics describe within a VPath that may have several such paths. For example, a path named "Broadband-to-Broadband" showing high packet loss, while the VPath's MPLS-based path stays clean, tells the admin the broadband circuit at one end is the specific weak link.
