| 520 | |a Abstract The ever-expanding growth of internet traffic enforces deployment of massive Data Center Networks (DCNs) supporting high performance communications. Optical switching is being studied as a promising approach to fulfill the surging requirements of large scale data centers. The tree-based optical topology limits the scalability of the interconnected network due to the limitations in the port count of optical switches and the lack of optical buffers. Alternatively, buffer-less Fast Optical Switch (FOS) was proposed to realize the nanosecond switching of optical DCNs. Although FOSs provide nanosecond optical switching, they still suffer from port count limitations to scale the DCN. To address the issue of scaling DCNs to more than two million servers, we propose the hyper scale FOS-based L-level DCNs (HFOS%$_L%$) which is capable of building large networks with small radix switches. The numerical analysis shows L of 4 is the optimal level for HFOS%$_L%$ to obtain the lowest cost and power consumption. Specifically, under a network size of 160,000 servers, HFOS%$_4%$ saves 36.2% in cost compared with the 2-level FOS-based DCN, while achieves 60% improvement for cost and 26.7% improvement for power consumption compared with Fat tree. Moreover, a wide range of simulations and analyses demonstrate that HFOS%$_4%$ outperforms state-of-art FOS-based DCNs by up to 40% end-to-end latency under DCN size of 81920 servers. | ||

Optical switching is being studied as a promising approach to fulfill the surging requirements of large scale data centers. The tree-based optical topology limits the scalability of the interconnected network due to the limitations in the port count of optical switches and the lack of optical buffers. Alternatively, buffer-less Fast Optical Switch (FOS) was proposed to realize the nanosecond switching of optical DCNs. Although FOSs provide nanosecond optical switching, they still suffer from port count limitations to scale the DCN. To address the issue of scaling DCNs to more than two million servers, we propose the hyper scale FOS-based L-level DCNs (HFOS%$_L%$) which is capable of building large networks with small radix switches. The numerical analysis shows L of 4 is the optimal level for HFOS%$_L%$ to obtain the lowest cost and power consumption. Specifically, under a network size of 160,000 servers, HFOS%$_4%$ saves 36.2% in cost compared with the 2-level FOS-based DCN, while achieves 60% improvement for cost and 26.7% improvement for power consumption compared with Fat tree. Moreover, a wide range of simulations and analyses demonstrate that HFOS%$_4%$ outperforms state-of-art FOS-based DCNs by up to 40% end-to-end latency under DCN size of 81920 servers.

Optical switching is being studied as a promising approach to fulfill the surging requirements of large scale data centers. The tree-based optical topology limits the scalability of the interconnected network due to the limitations in the port count of optical switches and the lack of optical buffers. Alternatively, buffer-less Fast Optical Switch (FOS) was proposed to realize the nanosecond switching of optical DCNs. Although FOSs provide nanosecond optical switching, they still suffer from port count limitations to scale the DCN. To address the issue of scaling DCNs to more than two million servers, we propose the hyper scale FOS-based L-level DCNs (HFOS%$_L%$) which is capable of building large networks with small radix switches. The numerical analysis shows L of 4 is the optimal level for HFOS%$_L%$ to obtain the lowest cost and power consumption. Specifically, under a network size of 160,000 servers, HFOS%$_4%$ saves 36.2% in cost compared with the 2-level FOS-based DCN, while achieves 60% improvement for cost and 26.7% improvement for power consumption compared with Fat tree. Moreover, a wide range of simulations and analyses demonstrate that HFOS%$_4%$ outperforms state-of-art FOS-based DCNs by up to 40% end-to-end latency under DCN size of 81920 servers.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Fast optical switch</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Optical data center network</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Low latency interconnection</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Scalable data center network</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hessabi, Shaahin</subfield><subfield code="0">(orcid)0000-0003-3193-2567</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Koohi, Somayyeh</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yan, Fulong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Calabretta, Nicola</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Telecommunication systems</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1993</subfield><subfield code="g">80(2022), 3 vom: 17.

HFOS%$_L%$: hyper scale fast optical switch-based data center network with L-level sub-network |
| abstract |
Abstract The ever-expanding growth of internet traffic enforces deployment of massive Data Center Networks (DCNs) supporting high performance communications. Optical switching is being studied as a promising approach to fulfill the surging requirements of large scale data centers. The tree-based optical topology limits the scalability of the interconnected network due to the limitations in the port count of optical switches and the lack of optical buffers. Alternatively, buffer-less Fast Optical Switch (FOS) was proposed to realize the nanosecond switching of optical DCNs. Although FOSs provide nanosecond optical switching, they still suffer from port count limitations to scale the DCN. To address the issue of scaling DCNs to more than two million servers, we propose the hyper scale FOS-based L-level DCNs (HFOS%$_L%$) which is capable of building large networks with small radix switches. The numerical analysis shows L of 4 is the optimal level for HFOS%$_L%$ to obtain the lowest cost and power consumption. Specifically, under a network size of 160,000 servers, HFOS%$_4%$ saves 36.2% in cost compared with the 2-level FOS-based DCN, while achieves 60% improvement for cost and 26.7% improvement for power consumption compared with Fat tree. Moreover, a wide range of simulations and analyses demonstrate that HFOS%$_4%$ outperforms state-of-art FOS-based DCNs by up to 40% end-to-end latency under DCN size of 81920 servers. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022 |
