This is the name of a dynamically RSVP-TE-signaled, co-routed bidirectional GMPLS tunnel, sharing naming convention with static tunnels per the description but distinguished by the automatic signaling and forced same-path-both-directions behavior of a co-routed circuit. An admin names these to reflect the service they carry, since unlike a static co-routed tunnel this one can automatically re-signal both directions together around a failure while still guaranteeing symmetric latency. For example, a name like dynamic-corouted-voice-trunk-3 tells the admin this signaled circuit backs a latency-symmetric voice service.
