Abstract
A system can be provided that can detect a transmission failure of a packet. The transmission failure can occur in a software-defined network. The system can further identify, via debuggers, functions associated with the transmission failure of the packet. The transmission failure of the packet can occur between components in the software-defined network. Additionally, the system can generate, via the debuggers, log data for the functions. The system can also identify, based on the log data, a function associated with the transmission failure and a cause of the transmission failure related to the function.
Claims20
A system comprising:
- a processing device;
- and
- a memory device that includes instructions executable by the processing device for causing the processing device to perform operations comprising:
- detecting a transmission failure of a packet, the transmission failure occurring in a software-defined network;
- identifying, via at least one debugger, a plurality of functions associated with the transmission failure of the packet between components in the software-defined network;
- generating, via the at least one debugger, log data for the plurality of functions by:
- detecting the transmission failure of the packet from a first component of the software-defined network to a second component of the software-defined network;
- pairing a debugger with the first component or with the second component to generate the log data for a first function associated with sending the packet or for a second function associated with receiving the packet;
- determining, based on the log data, whether the first function or the second function is responsible for the transmission failure;
- and
- identifying, based on the log data, a cause of the transmission failure related to the plurality of functions.
A method comprising:
- detecting a transmission failure of a packet, the transmission failure occurring between at least two components of a software-defined network;
- pairing at least one debugger with at least one of the at least two components of the software-defined network;
- identifying, via the at least one debugger paired with the at least one of the at least two components, a plurality of functions associated with the transmission failure of the packet between the at least two components in the software-defined network;
- generating, via the at least one debugger paired with the at least one of the at least two components, log data for the plurality of functions;
- and
- identifying, based on the log data, a cause of the transmission failure related to the plurality of functions.
A non-transitory computer-readable medium comprising instructions that are executable by a processing device for causing the processing device to perform operations comprising:
- detecting a transmission failure of a packet, the transmission failure occurring between at least two components of a software-defined network;
- pairing at least one debugger with at least one of the at least two components of the software-defined network;
- identifying, via the at least one debugger paired with the at least one of the at least two components, a plurality of functions associated with the transmission failure of the packet between the at least two components in the software-defined network;
- generating, via the at least one debugger paired with the at least one of the at least two components, log data for the plurality of functions;
- and
- identifying, based on the log data, a cause of the transmission failure related to the plurality of functions.
