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.
Claims20
A method for determining reliability of communications between network nodes, the method comprising:
- generating a test packet including a plurality of nested data packets, each nested data packet from the plurality of nested data packets including an identifier of a destination node from one of a first network node and a second network node;
- causing the test packet to be transmitted between the first network node and the second network node in accordance the identifier of the destination node from each nested data packet;
- and
- determining a reliability of a link between the first network node and the second network node based on an error rate of the link, the error rate of the link being based on a number of nested data packets from the plurality of nested data packets and whether the test packet is determined to arrive at a final destination node.
A method for determining reliability of communications between network nodes, the method comprising:
- generating a plurality of test packets, each test packet including a plurality of nested data packets, each nested data packet from the plurality of nested data packets including an identifier of a destination node from one of a first network node and a second network node;
- causing the plurality of test packets to be transmitted between the first node and the second node in accordance with the identifier of the destination node from each nested data packet;
- and
- determining a reliability of a link between the first network node and the second network node based on an error rate of the link, the error rate of the link being based on a number of test packets from the plurality of test packets received at a final destination node.
A system for determining reliability of communications between network nodes, the system comprising:
- one or more processors;
- memory in electronic communication with the one or more processors;
- and
- instructions stored in the memory, the instructions being executable by the one or more processors to:
- generate a plurality of test packets, each test packet including a plurality of nested data packets, each nested data packet from the plurality of nested data packets including an identifier of a destination node from one of a first network node and a second network node;
- cause the plurality of test packets to be transmitted between the first node and the second node in accordance with the identifier of the destination node from each nested data packet;
- and
- determine a reliability of a link between the first network node and the second network node based on an error rate of the link, the error rate of the link being based on a number of test packets from the plurality of test packets received at a final destination node.
