Network link testing using IP-in-IP encapsulation

Abstract:

Increasing a resolution of an error rate detectable on a link between two network nodes includes transmitting an IP-in-IP encapsulated test packet back and forth between the two network nodes. The test packet includes a series of nested data packets having alternating destinations between the two network nodes. The test packet is transmitted on the data plane of the network, thereby increasing the resolution of the detectable error rate.
