PACKET TRACING IN A SOFTWARE-DEFINED NETWORKING ENVIRONMENT

摘要

An example method to perform packet tracing in a Software-Defined Networking (SDN) environment is provided. The SDN environment comprises an SDN controller device and a plurality of forwarding devices configurable by the SDN controller device. The method may comprise the SDN controller device configuring the plurality of forwarding devices to generate trace information of packets associated with a communication flow in the SDN environment; and receiving trace information of packets associated with the communication flow. Based on the trace information, the SDN controller device may generate aggregated trace information by identifying, from header information and payload information of the packets, particular packets associated with the communication flow that are processed by one of the plurality of forwarding devices, or a particular packet associated with the communication flow that is processed by at least two of the plurality of forwarding devices, or both.

1. A method for a Software-Defined Networking (SDN) controller device to perform packet tracing in an SDN environment that includes the SDN controller device and a plurality of forwarding devices configurable by the SDN controller device, the method comprising:
configuring the plurality of forwarding devices to generate trace information of packets associated with a communication flow in the SDN environment; receiving, from the plurality of forwarding devices, trace information of packets associated with the communication flow, wherein the trace information includes header information and payload information of the packets; and based on the trace information, generating aggregated trace information by identifying, from the header information and payload information of the packets, particular packets associated with the communication flow that are processed by one of the plurality of forwarding devices, or a particular packet associated with the communication flow that is processed by at least two of the plurality of forwarding devices, or both.
