A buffer scheduling method is provided for use in an Internet data center in which flows are transmitted in a 'Hybrid Switching Mode' using both an optical circuit switch and an electrical circuit switch or in an 'All-optical Switching Mode' using only the optical circuit switch, to improve the overall switch throughput. In the &#x201c;Hybrid Switching Mode,&#x201d; an offloading scheme can be used; in the &#x201c;All-optical Switching Mode,&#x201d; a discard scheme, a padding scheme, a free-riding scheme, an aggregate scheme or a smart scheme can be used. During the transitioning stage of the technology, the offloading scheme can be used in the &#x201c;Hybrid Switching Mode&#x201d; to achieve significant improvement in the overall switching efficiency, whereas in the all-optical switching field, the free-riding scheme, the aggregate scheme and the smart scheme can be used to achieve good switching efficiency in the &#x201c;All-optical Switching Mode.&#x201d;
