Title: METHOD AND APPARATUS FOR DETERMINING DATA TRANSFER SEQUENCES BETWEEN MULTI-INGRESS AND MULTI-EGRESS
Abstract:
The objective of the present invention is to provide a method and apparatus for determining data transfer sequences between multi-ingress and multi-egress. The method for determining data transfer sequences between multi-ingress and multi-egress is provided. Herein the number of ingress and egress are both N and the data to be transferred from the multi-ingress constitute a N*N data matrix; wherein the depth of each ingress is M which indicates the number of the transfer cycle for transferring the data matrix; wherein in each transfer cycle, the method comprises the following steps: a. determining the transfer cost of every non-zero element in the matrix based on the cross-attribute and value-attribute of the every non-zero element, and determining that the transfer cost of a zero element is zero; b. selecting an element of the maximum cost from the cost determined elements; c. disregarding the row and column of the selected element, and returning to step a to re-determine the transfer cost of the rest elements in the matrix, till only one element is left to re-determine the transfer cost; d. determining a data transfer sequence based on N data samples, wherein each data sample is obtained from one of the N selected elements.
