摘要

In the multi-granularity optical switching system with optical-code granularity, the wavelength and optical code resource reservation table is established in the PCE domain according to the PCEP common standard, which effectively solves the problem of reserved optical-code conflict in the resource reservation request process, and reasonably allocates utilize the optical code resources in the optical network. At the same time, based on the principle of multi-granularity optical code switching, the exchange path computation algorithm of multi-granularity switching system refined to optical-code packet granularity is studied, and a new routing and optical-code assignment (ROCA) scheme is given. An optical-code fragment minimization allocation algorithm is proposed, which adaptively routes resources according to service segmentation and optical-code polling, rationally utilizes optical-code resources in wavelengths, and effectively reducing optical-code fragments and improving used wavelengths. Furthermore, the blocking rate of the network is reduced. Compared with the First-Fit algorithm, this algorithm reduces the blocking rate of the network and improves the throughput of the network.
