Document Type and Number:
WIPO Patent Application WO/2020/228674
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an optical network system and a method for scheduling same, and a data center interconnection network. In the embodiments of the present application, the optical network system comprises a plurality of sub-networks, wherein at least one sub-network comprises an ROADM; and at least one of the other sub-networks except the sub-network which includes the ROADM comprises an optical path selector; and optical interconnection is carried out among the various sub-networks by means of the ROADM and the optical path selector. Thus, directly connected optical link connection is not required between sub-networks, between which the optical connection is realized by an ROADM, such that the optical connection between the sub-networks can be realized, the number of optical links can be reduced, simplification of an interconnection structure of an optical network system is facilitated, and network cost is reduced.
