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.

First claim

What is claimed is:

1. A computer system embodied in hardware for managing workloads in a network, wherein the network comprises a data network and an independent management network, the system comprising:
at least one switch included in the data network, the at least one switch comprising at least one buffer;
wherein said at least one switch comprises at least one of a Hadoop network switch and a software-defined network (SDN) enabled switch;
wherein said at least one switch performs a method comprising:
receiving data associated with a workload from a server, wherein the workload is part of a shuffle phase of a map-reduce algorithm;
tagging said data with an unique identifier that associates the data with the workload;
determining that the switch is not over-subscribed when second data stored in that at least one buffer of the switch does not exceed a threshold, and determining that the switch is over-subscribed when the second data stored in the at least one buffer of the switch exceeds the threshold;
wherein the threshold is selected based on at least one of: a throughput requirement associated with said network comprises said data network and said independent management network, an anticipated maximum rate of incoming data at said at least one switch, and a capacity of said at least one buffer in said at least one switch;
compressing the received data based on determining that the second data stored in the at least one buffer exceeds the threshold when the switch is over-subscribed;
storing the compressed data in the at least one buffer; and
transmitting the compressed data and the unique identifier to a controller of said independent management network in response to determining that the at least one switch in the first network is over-subscribed such that spare bandwidth available in said independent management network is leveraged and utilized to transfer the compressed data while the at least one switch is over-subscribed so as to manage the workload between said data network and said independent management network;
receiving, from said controller, said unique identifier and sub-results associated with a processing of said compressed data by said controller;
merging said sub-results with second sub-results identified by said unique identifier to generate overall results;
decompressing said overall results; and
transmitting said overall results to a final destination.
