Background

Optical networks play a vital role in today's global information and communication infrastructure. Due to the limitation of wavelength conflict in the optical network, the wavelength fragmentation in the optical network is serious, so that the capacity of the optical network and the utilization rate of optical network resources are low.

In the case where no route has been arranged in the optical fiber network, the current network structure is not limited to include only the wave plane and the virtual nodes, that is, no virtual link has been constructed between each virtual node.

The service list comprises at least one service, each service indicates an active node and a target node, and the service route is a route connecting the active node and the target node and is used for realizing a task of establishing a communication channel between the active node and the target node.

And S204, under the condition that the service route corresponding to each service in the service list is determined, acquiring the wave-plane conversion parameters of the target virtual node with the all-optical wavelength converter according to the connection relation between the virtual nodes in the service route.

In S204, the all-optical wavelength converter is used to construct virtual links between target virtual nodes of different wave planes. The all-optical wavelength converter realizes the wave plane conversion on the virtual node by connecting the virtual nodes corresponding to different wave planes, and realizes the wavelength conversion on the node corresponding to the all-optical wavelength converter in an optical fiber network, so that the all-optical wavelength converter utilizes different wavelengths to carry out communication.

Each service in the service list is not limited to determining a service route for each service in turn according to the order of the service in the service list. In the case where the number of selectable routes corresponding to one service is plural, it is not limited to determining one service route among the plural selectable routes, so as to determine a service route for the service, which is ultimately used for communication.

And under the condition that the service routes corresponding to all services in the service list are determined, determining the connection relation among the virtual nodes and the positions of all-optical wavelength converters arranged for realizing the service routes. And determining the nodes with the all-optical wavelength converters as target virtual nodes, and determining wave plane conversion parameters of the target virtual nodes, namely the conversion number and the conversion range of wave plane conversion on the target virtual nodes.

In the embodiment of the present application, in response to a service allocation request, determining a service route including at least one virtual link corresponding to each service in a service list in a current network structure including a wave plane corresponding to each wavelength and a virtual link connecting virtual nodes in the wave plane, acquiring, according to a connection relationship between virtual nodes in the service route, a wave-plane conversion parameter of a target virtual node of an all-optical wavelength converter arranged with an all-optical wavelength converter for constructing a virtual link between target virtual nodes of different wave planes, when a service route is determined for each service in the service list by simulation in a current network result, a connection relationship of virtual nodes in the determined service route is adopted, the method comprises the steps of determining a target virtual node where an all-optical wavelength converter needs to be arranged, determining the type of the all-optical wavelength converter needing to be arranged on the target virtual node according to wave plane conversion parameters of the target virtual node, and achieving the purpose of determining the position and the type of the all-optical wavelength converter needing to be arranged while determining a service route, so that the type of the all-optical wavelength converter is determined based on the requirement of the service route, the technical effect that the wavelength range of the all-optical wavelength converter is matched with the actual requirement is achieved, and the technical problem that the all-optical wavelength converter is not matched with the actually required wavelength conversion range due to fixation of the all-optical wavelength converter is solved.

As an optional implementation manner, as shown in fig. 3, before determining a corresponding service route for each service in the service list in the current network structure, the method further includes:

s302, constructing a corresponding wave plane for each wavelength;

s304, determining the node connection relation among all virtual nodes in each wave plane;

s306, determining a virtual link in the wave plane according to the node connection relation so as to determine the current network structure.

The current network architecture for analog traffic routing determination and determination of the type of all-optical wavelength converters is constructed and determined by individual wave planes and node connection relationships within the wave planes, plane connection relationships between the wave planes. And constructing a corresponding wave plane for each wavelength supported in the optical fiber network, and setting a virtual node corresponding to the physical node in the optical fiber network in each wave plane. When the virtual nodes communicate with each other by using the wavelength, the two virtual nodes in the wave plane corresponding to the wavelength are connected, and the node connection relation before each virtual node in each wave plane is determined in turn.

In the case where an all-optical wavelength converter has been arranged on a virtual node, the current conversion range of the current all-optical wavelength converter is determined to determine that wave plane based on the planar connectivity of the virtual node with other wave planes. The all-optical wavelength converter is used for establishing virtual links between different wave planes within a wavelength conversion range, the virtual links between the virtual nodes are not used for establishing virtual links between different virtual nodes between different wave planes, and the different virtual nodes between different wave planes are connected based on the virtual links between the virtual nodes in the wave planes after wave plane conversion is carried out through the virtual nodes in which the all-optical wavelength converter is arranged.

As an alternative implementation, as shown in fig. 4, the determining, in the current network structure, a service route corresponding to each service in the service list includes:

s402, determining a source node and a target node indicated by each service, wherein the source node and the target node are respectively end nodes of a service route;

s404, using a source node as an initial virtual node, and determining a plurality of virtual link sets communicated to a target node in a current network structure, wherein each virtual link set comprises at least one virtual link;

s406, calculating the route cost corresponding to each virtual link set in the multiple virtual link sets, and determining the route corresponding to the virtual link set with the minimum route cost as the service route.

And determining a virtual link set capable of communicating the source node and the target node according to the source node and the target node indicated by the service, wherein at least one virtual link in the virtual link set is sequentially connected to form a communication route from the source node to the target node.

In the case that there is more than one virtual link set, the virtual link set with the minimum routing cost is not limited to determining the virtual link set as the service route corresponding to the service. The routing cost is determined by the link cost of each virtual link, and the link cost of the virtual link between the same wave planes is different from the link cost of the virtual link connecting different wave planes. While virtual links connecting different wave planes require the placement of all-optical wavelength converters to achieve, the link cost of virtual links connecting different wave planes is not limited to that associated with the placement of all-optical wavelength converters. For example, the higher the cost of the all-optical wavelength converter, the higher the link cost of the corresponding virtual link.

In the case that the route costs of at least two of the virtual link sets are the same, the service route is not limited to be randomly determined in the at least two virtual link sets, and the service route may be determined by using a virtual link set with a smaller number of virtual links included in the virtual link set as the service route, or by using another method.

As an optional implementation manner, as shown in fig. 5, the calculating a routing cost corresponding to each of the multiple virtual link sets includes:

s502, obtaining at least one candidate virtual link included in the virtual link set;

s504, under the condition that the candidate virtual link indicates to connect two virtual nodes in the same wave plane, determining the link cost of the candidate virtual link as a first numerical value;

s506, under the condition that the candidate virtual link indicates to connect with corresponding virtual nodes in different wave planes, determining the virtual node as a candidate conversion node, and determining the link cost of the candidate virtual link based on the wavelength conversion parameter of the candidate conversion node;

and S508, calculating the sum of the link costs of all the candidate virtual links in the virtual link set to obtain the routing cost of the virtual link set.

And sequentially acquiring each candidate virtual link according to the connection sequence of the candidate virtual links in the virtual link set, determining the link cost of the candidate virtual links, and determining the sum of the link costs of all the candidate virtual links as the routing cost.

When the candidate virtual link indicates to connect two virtual nodes in the same wave plane, the link cost of the candidate virtual link is determined to be a first value, for example, 1.

Under the condition that the candidate virtual link indicates to connect corresponding virtual nodes in different wave planes, the virtual node is determined as a candidate conversion node, and the link cost of the candidate virtual link is determined based on the wavelength conversion parameter of the candidate conversion node.

As an optional implementation manner, after the determining the virtual node as the candidate conversion node, the method further includes: and under the condition that the number of the candidate conversion nodes in the virtual link set is greater than a preset node threshold value, determining the route cost corresponding to the virtual link set as a third numerical value.

In the case of determining the candidate conversion nodes, the number of candidate conversion nodes included in the virtual link set is not limited to be determined first. And under the condition that the number of the candidate conversion nodes is greater than a preset node threshold value, directly determining the routing cost corresponding to the virtual link set as a third numerical value.

The number of the candidate conversion nodes is the number of times of wave plane conversion needed in the candidate service route corresponding to the virtual link set, that is, the number of times of wavelength conversion needed in actual deployment, and the number of times of wave plane conversion needed in the service route is limited by setting a preset node threshold, so that excessive route cost caused by excessive wave plane conversion times in the same route is avoided. Because each conversion of the primary wave plane needs to be realized by a wavelength converter, the number of wavelength converters arranged in the whole network is controlled by a preset node threshold value, so that the deployment cost of the all-optical wavelength converter is reduced.

Alternatively, the third value may be a value much larger than the first value and the other values, so that in the case where the route cost is determined to be the third value, it is determined that the virtual link set is a virtual link set that is not selected as a traffic route. For example, "infinity" is selected as the third value.

As an alternative implementation, as shown in fig. 6, the determining the link cost of the candidate virtual link based on the wavelength conversion parameter of the candidate conversion node includes:

s602, determining a link cost of a candidate virtual link as a second numerical value when the all-optical wavelength converter is not disposed on the candidate conversion node, where the second numerical value is greater than the first numerical value;

s604, in a situation that the all-optical wavelength converters are arranged on the candidate conversion nodes, determining a current conversion number of the all-optical wavelength converters, and determining a link cost of the candidate virtual link according to the current conversion number, where the link cost is positively correlated with the current conversion number.

The wavelength conversion parameters of the candidate conversion nodes include whether all-optical wavelength converters are arranged and the current number of conversions of all-optical wavelength converters. In case the wavelength conversion parameter indicates that no all-optical wavelength converters are arranged on the candidate conversion node, the link cost of the candidate virtual link is determined as a second value, where the second value is much larger than the first value. For example, in the case where the first value is 1, the second value is set to 100.

And under the condition that the wavelength conversion parameters indicate that all-optical wavelength converters are arranged on the candidate conversion nodes, determining corresponding link costs according to the current conversion number of the all-optical wavelength converters. The current number of transitions is not limited to the number of transitions that comprise the candidate virtual link. The larger the current number of transitions, the larger the corresponding link cost. For example, in the case that the current number of transitions is less than 10, the corresponding link cost is 0.1; under the condition that the current conversion number is more than or equal to 10 and less than 15, the corresponding link cost is 2; under the condition that the current conversion number is greater than or equal to 15 and less than or equal to 20, the corresponding link cost is 5; in the case where the current number of transitions is greater than 20, the corresponding link cost is infinite.

As an alternative embodiment, as shown in fig. 7, the determining the type of the all-optical wavelength converter according to the wave-plane conversion parameter includes:

s702, determining the conversion number and the conversion range of wave-plane conversion on a target virtual node, wherein wave-plane conversion parameters comprise the conversion number and the conversion range;

and S704, determining the type of the all-optical wavelength converter corresponding to the target virtual node according to the conversion number and the conversion range, wherein the type of the all-optical wavelength converter is used for indicating the wavelength conversion capability of the all-optical wavelength converter.

The type of all-optical wavelength converter is used to indicate the conversion capability of the all-optical wavelength converter, including the conversion range and the number of conversions. The conversion range is used to indicate the range of wavelengths that can be converted and the number of conversions is used to indicate the number of wavelengths that can be converted. The conversion range is generally determined by the location of the node and the number of conversions, and is not limited to the number of wavelengths adjacent to the location of the node as the conversion range of the all-optical wavelength converter.
