Abstract

Embodiments include a method, system, and computer program product for managing workloads in a network. A switch receives data associated with a workload. The received data is tagged with an identifier that associates the data with the workload. The received data is compressed based on determining that second data stored in a buffer of the switch exceeds a threshold. The switch stores the compressed data in the buffer. The compressed data is transmitted to a second network based on a determination that the switch is over-subscribed.

Claims

1-16. -16. (canceled)

17. A computer system for managing workloads in a network, the system comprising:

at least one switch comprising at least one buffer and that performs a method comprising;

receiving data associated with a workload from a server;

tagging the received data with an identifier that associates the data with the workload;

compressing the received data based on determining that second data stored in the at least one buffer exceeds a threshold;

storing the compressed data in the at least one buffer; and

transmitting the compressed data to a second network based on a determination that the at least one switch is over-subscribed.

18. The computer system of claim 17, wherein the threshold is selected based on at least one of:

a throughput requirement associated with the network, an anticipated maximum rate of incoming data at the at least one switch, and a capacity of the at least one buffer, and wherein the at least one switch comprises at least one of;

a HADOOP network switch and a software-defined network (SDN) enabled switch.

19. The computer system of claim 17, wherein the second network comprises an independent management network, and wherein the method performed by the at least one switch further comprises:

transferring the compressed data and the identifier to a controller of the independent management network based on determining that the at least one switch is over-subscribed.

20. The computer system of claim 19, wherein the method performed by the at least one switch further comprises:

receiving, from the controller, the identifier and sub-results associated with a processing of the data by the controller;

merging the sub-results with second sub-results identified by the identifier to generate overall results;

decompressing the overall results; and

transmitting the overall results to a final destination.
