Abstract:
1. A computer implemented method of operations performed at a node in a network in communication with remote nodes in the network, comprising: determining the remote nodes in the network; determining network performance information based on a measured network transmission rate with respect to transmitting to the determined remote nodes; determining compression performance information with respect to the node executing a compression algorithm to compress test data within the node, wherein the compression performance information is based on a current load and performance in the node when compressing the test data; transmitting the determined compression performance information to the remote nodes over the network; receiving from the remote nodes decompression performance information with respect to the remote nodes executing a decompression algorithm to perform decompression operations within the remote nodes, wherein the decompression performance information from the remote nodes is based on a current load and performance at the remote nodes executing the decompression algorithm; using the determined compression performance information and the received decompression performance information to determine a computational performance value for executing the compression algorithm at the node; determining a compression ratio (CR) resulting when the compression algorithm compresses the test data to transmit; and comparing the determined computational performance value to a ratio of the network performance information and the CR to determine whether to execute the compression algorithm at the node, wherein the ratio of the network performance information and the CR is calculated according to an equation comprising 2*NTR/(1−CR), wherein NTR is the measured network transmission rate.
