Abstract
In one implementation, a device receives, at a port of the device, a measurement packet from a sender in the network. The device obtains a destination address from the measurement packet. The device replaces, as a dataplane operation, the destination address of the measurement packet with an updated destination address associated with the sender. The device sends the measurement packet back to the sender using the updated destination address.
Claims20
A method comprising:
- receiving, at a port of a device in a network, a measurement packet from a sender in the network;
- obtaining, by the device, a destination address from the measurement packet;
- replacing, by the device and as a dataplane operation, the destination address of the measurement packet with an updated destination address associated with the sender;
- and
- sending, by the device, the measurement packet back to the sender using the updated destination address.
An apparatus, comprising:
- a processor configured to execute one or more processes;
- and
- a memory configured to store a process that is executable by the processor, the process when executed configured to:
- receive, at a port of the apparatus, a measurement packet from a sender in a network;
- obtain a destination address from the measurement packet;
- replace, as a dataplane operation, the destination address of the measurement packet with an updated destination address associated with the sender;
- and
- send the measurement packet back to the sender using the updated destination address.
A tangible, non-transitory, computer-readable medium storing program instructions that cause a device in a network to execute a process comprising:
- receiving, at a port of the device in the network, a measurement packet from a sender in the network;
- obtaining, by the device, a destination address from the measurement packet;
- replacing, by the device and as a dataplane operation, the destination address of the measurement packet with an updated destination address associated with the sender;
- and
- sending, by the device, the measurement packet back to the sender using the updated destination address.
