A method and device for computing a global concurrent optimization path, and a non-transitory computer-readable storage medium are disclosed. The method may include: computing, by a PCE, an actual path for each of at least one service sequentially based on a topology to serve as an actual best path; allocating, by the PCE, an actual spectrum resource sequentially for the actual path, to serve as an actual best spectrum resource; computing, by the PCE, an actual target value for all services in accordance with a target function, to serve as an actual best target value; and reordering a subset of services, recomputing an actual path for each of the subset of services and reallocating a spectrum resource, recomputing an actual target value for all services, updating the actual best target value, and updating the actual best path and the actual best spectrum resource, by the PCE.

Method and device for computing global concurrent optimization path, and computer readable storage medium

Provided are a service operation method, a service operation device a storage medium and an electronic device. The method includes: determining service information about multiple nodes in a distributed network after determining a link failure in the distributed network, computing a restore path centralizedly for services indicated by the service information about the multiple nodes, and operating the services by using the restore path.

Service operation method and device, and storage medium and electronic device

Disclosed are a spectrum allocation method and device for an optical network and a computer storage medium. The method comprises: segmenting a service path of an optical network to obtain at least one path segment; trying to allocate, in sequence, for each path segment of the service path a service processing manner that satisfies a service spectrum requirement; and when the service processing manner satisfies the service spectrum requirement, allocating a frequency used by each path segment on the service path according to the currently allocated service processing manner of each path segment of the service path.
