Nokia’s Service ping feature provides end-to-end connectivity testing for an individual service. Service ping operates at a higher level than the SDP diagnostics in that it verifies an individual service and not the collection of services carried within an SDP.
Service ping is initiated from a router to verify round-trip connectivity and delay to the far-end of the service. Nokia’s implementation functions for both GRE and MPLS tunnels and tests the following from edge-to-edge:
tunnel connectivity
VC label mapping verification
service existence
service provisioned parameter verification
round trip path verification
service dynamic configuration verification
