Description
Technical field
The present invention relates to optical-fiber network frequency spectrum resource distribution field, in particular to one based on time frequency spectrum continuous print method for obligating resource, device and processor.
Background technology
Flourish along with Internet service, network faces high bandwidth, the business demand of strong burst and challenge, in the urgent need to having feature dynamic, efficient. Support that the flexible optical-fiber network of frequency spectrum that spectrum efficient utilizes is taken advantage of a situation generation. In the flexible optical-fiber network of frequency spectrum, by adopting OFDM (OrthogonalFrequencyDivisionMultiplexing, OFDM) technology, dynamically resource suitable accordingly can be dynamically distributed for varigrained teleservice, thus improve utilization rate and the service transmission rate of resources in network based on certain strategy. Relative to traditional WDM (WavelengthDivisionMultiplexing, wavelength-division multiplex) network, the advantage of the flexible optical-fiber network of frequency spectrum is in that it breaks through the restriction of original optical-fiber network fixed-grid, realize the flexibility of grid, can better realize coupling and the flexible transmission of business, improve the utilization rate of frequency spectrum. And due to the appearance of SDON (SoftwareDefinedOpticalNetwork, software definition optical-fiber network), advance the differentiation of network control planes. SDON can make running software in network operating system, make optical-fiber network control to become more flexibly and motor-driven, simultaneously because the feature of its interface opening, what client can pass through interface calls cultivated fine-grained control Internet resources.
On the other hand, fast development along with the extensive use of the broadband services such as HD video, cloud service and data center, the new service that can overcome initial delay is asked, and such as video request program and the grid computing that network is made tremendous contribution, has promoted the improvement of bottom-layer network. In order to stand initial delay, resource reservation is a necessary selection. Guaranteeing that resource was assigned before service ending, what resource reservation distribution was different from common resource distribution is that resource reservation allows specific initial delay at the beginning of business is set up. Following flexible optical-fiber network of frequency spectrum can support that resource reservation is trend of the times.
EON (ElasticOpticalNetwork, the flexible optical-fiber network of frequency spectrum) adopt O-OFDM (Optical-OrthogonalFrequencyDivisionMultiplexing, light OFDM) technology, distribute frequency spectrum resource by dynamic mode flexibly and support channel operation asynchronous transmission speed. Under such a flexible architecture, optical fiber frequency spectrum is further divided into the frequency spectrum that a series of bandwidth is narrower. But, under a dynamic service scene, foundation and the dismounting of dynamic route will inevitably cause frequency spectrum fragment, the especially request of the AR on time dimension. Owing to frequency spectrum resource distribution excessively disperses, frequency spectrum resource fragment cannot carry business later; Frequency spectrum resource fragment makes network spectrum resource utilization be greatly lowered, because a lot of idle frequency spectrum resources are all that the form disperseing discrete wavelength coverage exists, the probability that cannot be re-used or re-use is only small, in the utilization rate being reduction of network spectrum resource, most research before all focuses on the resource reservation in WDM network.
Refer in the related about the method for resource reservation in the flexible optical-fiber network of frequency spectrum, but only considered dimension, i.e. a link dimension. Correlation technique relates to the scheduling of resource relevant with the time, but only highlights the time itself, and have ignored the suitable distribution of frequency spectrum.

The value of TSC is determined by A and B in this process, and the value of TSC represents the utilizable probability of continuous frequency spectrum resource. A represents frequency spectrum dimension and the percentage ratio of time dimension usable spectrum, and the value of A is more big, and the blocked probability of business is more low. B reflects the associating meansigma methods of the idle frequency spectrum block along frequency axis and time shaft, namely continuously available frequency spectrum. On link, available continuous frequency spectrum resource is more many, and the ratio on axle should be more high.
As shown in Figure 7 a, the continuous frequency spectrum resource on link is calculated. For link L1, it is assumed that current time tc=1. Each time quantum comprises 9 frequency spectrum blocks, therefore (T-tc+ 1) it is 2, F=9; Joint spectrum number respectively 7 and 5 along frequency spectrum axle and time shaft. At time tc=1 and tcHaving two identical frequency spectrum blocks when=2, also have 6 frequency spectrum blocks along time shaft, so always having 10 frequency spectrum blocks, so the definition according to above TSC, the TSC value of link L1 is 0.73. The TSC value of same link L2 and link L3 respectively 0.35 and 0.93. In the same way, we can calculate the TSC in the path being made up of link L1, L2, L3 is 0.32.
