Description

Resource reservation method, device and processor based on time spectrum continuation

Technical field

The present invention relates to the field of optical network spectrum resource allocation, and in particular to a time-frequency spectrum continuous resource reservation method, apparatus and processor.

Background technique

With the rapid development of Internet services, the network faces high bandwidth and strong bursts of business needs and challenges, and it is urgent to have more dynamic and efficient features. A spectrum-flexible optical network that supports the efficient use of spectrum generates a homeopathic trend. In the spectrum flexible optical network, by using OFDM (Orthogonal Frequency Division Multiplexing) technology, it is possible to dynamically allocate corresponding resources to end-to-end services of different granularities based on a certain policy dynamic, thereby improving the Resource utilization and service transmission rate in the network. Compared with the traditional WDM (Wavelength Division Multiplexing) network, the advantage of the spectrum flexible optical network is that it breaks through the limitation of the fixed grid of the original optical network, realizes the flexibility of the grid, and can better achieve the matching of the service. And flexible transmission to improve spectrum utilization. Due to the emergence of SDON (Software Defined Optical Network), the evolution of the network control plane has been promoted. SDON enables the software to run on the network operating system, making the control of the optical network more flexible and maneuverable. At the same time, due to the open interface, customers can control the network resources through the interface.

On the other hand, with the widespread use of broadband services such as high-definition video, the rapid development of cloud services and data centers, new service requests that can overcome initial delays, such as video on demand and grid computing that make a significant contribution to the network, Promoted improvements in the underlying network. In order to be able to tolerate the initial delay, resource reservation is a necessary choice. Ensure that resources are allocated before the end of the service. The resource reservation allocation is different from the normal resource allocation. The resource reservation allows a specific initial delay at the beginning of the service establishment. The future spectrum flexible optical network can support resource reservation is the general trend.

The EAO (Elastic Optical Network) uses O-OFDM (Optical-Orthogonal Frequency Division Multiplexing) technology to allocate spectrum resources in a flexible and dynamic manner to support the channel operation asynchronous transmission rate. Under such a flexible architecture, the fiber spectrum is further divided into a series of narrower bandwidths. However, in a dynamic business scenario, the establishment and removal of dynamic paths will inevitably lead to spectrum fragmentation, especially AR requests in the time dimension. Due to the excessive dispersion of spectrum resources, spectrum resource fragments cannot carry subsequent services; spectrum resource fragmentation greatly reduces the utilization of network spectrum resources, because many idle spectrum resources exist in the form of scattered non-contiguous spectrum segments, which cannot be The chances of reusing or reusing are small, thus reducing the utilization of network spectrum resources, most of the previous Research has focused on resource reservations in WDM networks.

A method for resource reservation in a spectrum flexible optical network is mentioned in the related art, but only one dimension, that is, a link dimension, is considered. Related techniques involve time-dependent resource scheduling, but only emphasize the time itself, while ignoring the proper allocation of spectrum.

In view of the problem that the spectrum resources under the flexible optical network based on software definition cannot be properly allocated in the related art, an effective solution has not been proposed yet.

Preferred embodiment 1

FIG. 7a and FIG. 7b are diagrams showing a time-frequency spectrum continuous manner. Based on FIG. 7a and FIG. 7b, the resource reservation method provided by this embodiment includes:

After the service arrives and the path is established, the spectrum resources on the link need to be calculated.

In order to better describe the occupancy of the spectrum, the concept of TSC (Time Spectrum Continuous) is introduced. The TSC is defined as:

among them,

with

The following formulas are respectively indicated:

Where t _c is the current time,

It is the sum of the available spectrum blocks of the link L along the time dimension and the spectrum dimension, respectively.

The spectrum occupancy on the link during the whole process is defined as a matrix [u _l ] _{T × F} ,

T represents the time unit and F represents the number of spectrum resources on each link. In the matrix

Is a bit value, 1 means that the spectrum slot at time t and f is idle, and 0 means that the spectrum is occupied.

Calculate the spectrum resources occupied on the entire path,

Where L(s,d) is the set of links on path p.

After knowing the number of spectrum resources on the link and the resources on the entire path,

The value calculates the TSC value of the entire path at time t _c

The value of TSC in this process is determined by A and B, and the value of TSC represents the likelihood that contiguous spectrum resources are available. A represents the percentage of available spectrum in the spectrum dimension and time dimension. The larger the value of A, the lower the probability that the traffic is blocked. B reflects the combined average of the free spectral blocks along the frequency and time axes, ie the continuously available spectrum. The more contiguous spectrum resources available on the link, the higher the ratio on the axis.

As shown in Figure 7a, continuous spectrum resources on the link are calculated. Taking link L1 as an example, assume that the current time t _c =1. Each time unit contains 9 spectral blocks, so (Tt _c +1) is 2, F = 9; the number of joint spectra along the spectral axis and the time axis are 7 and 5, respectively. There are two identical spectral blocks at times t _c =1 and t _c = 2, and there are 6 spectral blocks along the time axis, so there are a total of 10 spectral blocks, so the TSC of link L1 is defined according to the previous TSC. The value is 0.73. Similarly, the TSC values of link L2 and link L3 are 0.35 and 0.93, respectively. In the same way, we can calculate that the TSC with the path composed of links L1, L2, and L3 is 0.32.
