Abstract
The devices, systems, and methods test network connectivity, where the physical network is used to provide one or more service chains connecting service appliances, including firewalls, intrusion detection systems, load balancers, network address translators, web servers, and so on. A service chain may involve multiple routing paths. The devices, systems, and methods test network connectivity test network connectivity by injecting customized echo request packets on each routing path and collecting customized echo reply packets in response. The customized echo reply packets are processed and aggregated to isolate network connectivity problems.
