The 5G-oriented bearer device may access a plurality of service types, such as Common Public Radio Interface (CPRI), next generation Common Public Radio Interface (ECPRI), eth, and the like, and a flexE Interface or a conventional ethernet Interface is used on a network side.

CPRI is an interface between a radio equipment controller (BBU) and a radio equipment (RRU). CPRI may carry management data, synchronization data and user data, primarily involving the physical layer (L1) and the link layer (L2), supporting both optical and electrical interfaces.

Flexible ethernet (flexE) is an important technology for future network development, and flexible ethernet based on fragmentation technology will become a future trend. The application of the network fragmentation solution of the Ethernet interface in a large network realizes the flexible and flexible allocation (fragmentation and binding) of bandwidth and special hard pipelines, and ensures the quality of service and the safety; providing a low latency solution; and the method can be also fused with Software Defined Network (SDN) technology. In an operator network, the flexible ethernet based on the interface channelization technology can provide functions such as network fragmentation and sub-interface isolation, and support a future network architecture based on service experience.

If different types of services are accessed on the same physical port, greater flexibility is brought to an operator, so that the operator can select the type of the port to be accessed according to actual requirements, and can switch to another type of service on the unified physical port when switching is needed. In the related art, under the condition that different types of services need to be accessed, different types of physical access board cards are added on the equipment so as to access different types of services respectively by using the different types of physical access board cards. However, the resource of the device is limited, and if different types of access boards are added to the device, the size and cost of the device are inevitably increased.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

Example one

As shown in fig. 1, the present embodiment provides a method for port multiplexing, which is applied to a transmission device in the field of optical communication, and includes:

step 101, configuring port type information and associated service information of a physical port, so that the physical port supports a specified service;

102, issuing the configured port type information and the associated service information of the physical port to a logic chip;

step 103, when the message of the designated service is accessed through the physical port, the logic chip executes the forwarding processing of the message.

The method of the embodiment can adjust the port type and the associated service of the physical port according to the requirement, so that the same physical port can support the bearing of different types of services, and the forwarding of a pcs layer is realized by using the logic chip, so that different services can be accessed on the same physical port. For example, with the method of this embodiment, when the port carries a change of traffic, the port type can be switched from one type to another type on the same physical port without switching the physical port.

In this embodiment, the configuring port type information and associated service information of the physical port may include: acquiring configuration information of the specified service, wherein the configuration information indicates a port type corresponding to the specified service; and configuring the port type information and the associated service information of the physical port according to the configuration information of the specified service. In practical applications, there are various ways to obtain the specified service configuration information. Preferably, the obtaining mode may be: and extracting the specified configuration information by analyzing the message issued by the external control equipment. Here, the external control device may be a device responsible for management of a transmission device in an optical communication network, and for example, the external control device may be a controller in a network management system. In addition, the manner of acquiring the specified service configuration information may also be: and (4) inputting by a user. The specific manner of obtaining the service configuration information is not limited in the present application.

In this embodiment, the configuring port type information and associated service information of the physical port may include: judging whether preset configuration conditions are met or not; and when the configuration condition is met, configuring the port type information and the associated service information of the physical port. And when the configuration condition is not met, not executing the configuration of the physical port. In addition, when the configuration condition is not met, error information can be returned to the external control equipment, so that a user can acquire the configuration condition of the physical port in time.

In this embodiment, different determination methods may be adopted for different actual situations or actual scenes. For example, the determining whether the preset configuration condition is satisfied may include at least one or more of the following: 1) judging whether the physical port is bound with a service; the method comprises the steps that when a physical port is bound with a service, the configuration condition is considered not to be met, and when the physical port is not bound with the service or is unbound with the service, the configuration condition is considered to be met; 2) judging whether the physical port supports the port type corresponding to the specified service or not; wherein, when the physical interface supports the port type corresponding to the specified service, the configuration condition is considered to be satisfied, and when the physical interface does not support the port type corresponding to the specified service, the configuration condition is considered not to be satisfied, 3) whether a forced switching command is received is judged; and when the forced switching command is not received and the physical port is bound with the service or the physical port does not support the port type corresponding to the specified service, the configuration condition is considered to be not met.

The manner of determining whether the physical port has bound the service may be: and judging whether the port identification of the physical port is associated with the configuration information of the service. Specifically, if the port identifier of the physical port is associated with configuration information of a service, the physical port is considered as a bound service, and if the port identifier of the physical port is not associated with configuration information of any service, the physical port is considered as an unbound service or an unbound service. Here, the port identifier of the physical port is information capable of uniquely identifying the physical port, and may be, for example, a name of the physical port, a port number of the physical port, or the like.

Before configuring the port type information and the associated service information of the physical port, the method may further include: and when the physical port bears the service, unbinding the service borne on the physical port. In practical applications, it may be determined in advance whether a physical port already carries a service (the determination method is the same as the above "determining whether the physical port already carries a service"), if the physical port already carries a service, the service on the physical port may be unbundled, and if the physical port does not carry any service, the operation of unbundling may not be performed. In practical applications, there are various ways to unbundle the traffic already carried on the physical port. For example, the configuration information of the service associated with the port identifier of the physical port may be migrated (that is, the configuration information of the service may be associated with the port identifiers of other physical ports); for another example, the configuration information of the port identifier of the physical port that has been associated with the service may be directly deleted. In addition, there may be other ways, which do not limit the present application.

In this embodiment, before configuring the port type information and the associated service information of the physical port, the method may further include: when a forced switching command is received, the configuration information of the traffic associated with the port number of the physical port may be deleted. Therefore, the carried service on the physical port can be bound forcedly, and the physical port and the designated service can be bound forcedly.

In this embodiment, the port type information may include: the port identification, the port type identification and the port attribute parameter of the physical port; the associated service information may include: traffic configuration information associated with a port identification of the physical port. For example, when the port type is CPRI, the port type information may include: port name, port number, CPRI port type identification, port rate (common CPRI port rates include Option 1-Option 10 constant rate classes, actual rate from 614.4 Mbit/s-24330.24 Mbit/s). For another example, when the port type is an ethernet port, the port type information may include a port name, a port number, a port rate, an optoelectronic property, an access mode, a jumbo frame support, and the like.

In this embodiment, the configuring the port type information and the associated service information of the physical port may include: setting the physical port as a port type corresponding to the specified service, and configuring port attribute parameters for the physical port according to the port type; and associating the physical port with the configuration information of the specified service through the port identification of the physical port. In one case, the physical port may be configured in this manner when the physical port is initially configured. In another case, when the port bearer service changes, the physical port and the bearer service may be unbound (i.e., the configuration information of the bearer service is disassociated from the physical port), and then the physical port may be reconfigured in the above manner, so that the port type is switched from one type to another port type on the same physical port without switching the physical port.

In this embodiment, the process of the logic chip executing the forwarding processing of the packet may be: and the logic chip receives the port type information and the associated service information of the physical port and writes the port type information and the associated service information into a logic register. After the initialization of the port type and the actual service configuration are completed, when a message is accessed through the physical port, the logic chip transfers the message to the corresponding service processing logic to perform the forwarding processing of the message according to the service type of the message.

In this embodiment, before configuring port type information and associated service information of a physical port, it is further required to register a port type supported by the physical port in a port resource configuration table, so as to implement initialization of the physical port. In practical applications, port types that all physical ports can support may be stored in the port resource configuration table. For the case that the port types supported by the physical ports need to be expanded, the corresponding port types need to be added in the port resource configuration table first. In this way, the configuration of the port type information and the associated service information of the physical port may be executed by querying the port resource configuration table, whether the physical port supports the port type corresponding to the specified service may be determined by querying the port resource configuration table, a port identifier (for example, a port number) of the physical port may be queried by querying the port resource configuration table, and whether the port number is associated with the service configuration information may be determined to determine whether the physical port has bound the service.

In practical applications, a user-side port and a network-side port can be distinguished in a port resource configuration table. In practical applications, there may be unsupported scenarios for the port types supported by the user side and the port types supported by the network side. For example, user side port types a and b and network side port types c and d. If the port type a accessed by the user side does not support the load bearing on the port type d of the network side. The port resource configuration module can also be provided with a port mapping table, the port mapping table records the port type mapping combination of the user-side port and the network-side port, and whether the physical port supports the port type of the specified service can be judged by inquiring the port mapping table, namely whether the physical port can be changed into the corresponding port type is confirmed.

In practical application, when the configuration condition is not satisfied, error information can be returned. When the port bears the service, the port type switching can not be directly carried out, and the error information is returned. For combinations of unsupported user-side port types and network-side port types, the switching control module will return an error message.

In this embodiment, the process of issuing the configured port type information and the associated service information of the physical port to the logic chip may be: and calling an interface provided by the logic chip to send the port type information and the associated service information of the physical port.

In this embodiment, the port type information and the associated service information configuring the physical port may be divided into two cases: one is the case of first configuration and the other is the case where the traffic type accessed by the physical port needs to be switched.

In the case of initial configuration, during the initialization process, according to the port type supported by the physical port in the port resource configuration table, the physical port may be initialized by default to the first type port specified in the port resource configuration table, and may be used to continue to create a service on the port, so as to complete the actual bearer service configuration.

When the service type accessed by the physical port needs to be switched, the actual physical port is not changed, the service carried on the physical port can be deleted or migrated firstly, or the port type switching is forced, after the service configuration information associated with the physical port is removed, the port type information of the physical port is changed, the configuration information of the newly accessed service is associated with the physical port, and then the port type information of the physical port and the associated service information are sent to the logic chip, so that the port type switching of the physical port is completed.

In this embodiment, when the physical port is a user-side port, the port type of the physical port is one of the following: an Ethernet; CPRI; ECPRI; the newly expanded port type. When the physical port is a network-side port, the port type of the physical port is one of the following: ethernet, FlexE. Of course, the port type of the present application is not limited thereto. When a new extended port type appears in the related art, the physical port may also be the new extended port type.

The port resource configuration module 21, the port switching module 22, the command processing module 23, and the switching control module 24 in the port multiplexing apparatus may be software, hardware, or a combination of the two, respectively. For example, the port resource configuration module 21, the port switching module 22, the command processing module 23, and the switching control module 24 may be respectively implemented as software functional modules when the processor in the optical transmission device executes a corresponding port multiplexing program.

Exemplary implementations of the above embodiments are described in detail below. It should be noted that, in practical applications, the above embodiments may have other implementation manners, and the implementation manners of the flows and the execution steps in the following examples may also be adjusted according to the needs of practical applications.

Example 1

At the P node the traffic is directly forwarded from the flexE Group l to the flexE Group k, at which node the traffic is extracted from the flexE Group and then the valid 66b blocks are forwarded to the flexE Group k specific client N and then remapped to the flexE Group k specific slots. And at the PE2 node, extracting the time slot corresponding to the service from the Flex-e Group k, recovering the service into the corresponding service type, and sending the service from the node B.

Embodiments will describe implementations where port types switch over the same physical port for user-side and network-side ports, respectively.

The controller may be a device or a component in a network management system responsible for managing network transmission. Other implementation details in fig. 6 may refer to the above embodiments.

As shown in fig. 7, the initialization configuration and switching process of the user-side port is performed. It should be noted that the same physical port is multiplexed as an access-side port, and a plurality of common ports of ethernet, CPRI, and ECPRI are included on a user side. The network side comprises a plurality of Ethernet and flexE shared ports.

As shown in fig. 7, the initialization configuration and switching process of the user-side port may include the following steps:

The port resource configuration module sends the related port attribute to the port switching module by default, and the port switching module completes the initialization configuration of the logic chip. The port resource allocation module acquires actual plug board information and stores the actual plug board information in a storage, and reports the actual plug board information to the controller through rack information.

Here, the socket information may include a board type of the board, a board address, i.e., a slot address, physical port information (the number of physical ports and port number), and the like.

TABLE 1

Step 602: configuring the logic plugboard information: the controller generates the plug board port configuration information according to the actual plug board information reported by the port resource configuration module and sends the plug board port configuration information to the command processing module, and the command processing module analyzes the corresponding plug board port configuration information and generates logic plug board information to be stored in a warehouse. In this step, the port resource configuration module further compares the actual board plugging information with the put-in logical board plugging information, and reports a board type inconsistency alarm when the port number and the type are inconsistent, so that further configuration operation is not allowed. Further configuration operations on the port may also return an error prompt.

Step 603: port attribute configuration: after the logical plug board is configured, the configuration of the corresponding specific port attribute can be carried out. The port resource configuration module sends the port configuration information to the port switching module, and the port switching module further configures the logic chip to complete the configuration of the port information.

For example, according to the port resource configuration table, port No. 1 is initialized to be an ethernet port, and the attribute of the ethernet port may be further configured, where the basic parameters include a port name, a port number, a port rate, an optical-electrical attribute, an access mode, a jumbo frame support, and the like.

For example, according to the port resource configuration table, port No. 2 is initialized to the CPRI port, and the CPRI port attribute may be further configured. Including port name, port type, port rate (common CPRI port rates include Option 1-Option 10 equal rate classes, actual rates from 614.4-24330.24 Mbit/s).

Step 604: the service configures the associated port.

And after the configuration of the Ethernet port attribute is completed, an Ethernet service is established on the Ethernet port. After the CPRI port attribute configuration is completed, a CPRI service can be created on the CPRI port. The configuration information of the service may be stored in the configuration information table, and the service configuration information in the configuration information table is associated with the physical port through the port number.

Step 605: and switching the port types.

For the port which already carries the service, the service needs to be migrated or deleted first, and the port which releases the service can be switched in the port type. The switching control module checks the switching condition, if the switching condition is met, the switching control module notifies the port switching module, and the port switching module notifies the logic chip to perform actual switching processing. If the service is not migrated or deleted, the switching controller module returns an error message to the command processing module, and the switching is terminated.

For the physical port associated with the service, port switching can be performed through a forced port switching command, the command processing module issues the forced switching command to the switching control module, the switching control module deletes the service configuration corresponding to the port according to port number association, then notifies the port resource configuration module to reconfigure the physical port, and the port switching module issues the reconfigured related information to the logic information, thereby completing port type switching of the physical port.

So far, the initialization configuration and the switching scene of the physical port of the user side are completed.

Fig. 8 shows the initialization configuration and switching procedure of the network-side port in this example. As a network side port multiplexes the same physical port, the device comprises a plurality of Ethernet and flexE shared ports on the network side.

As shown in fig. 8, the initialization configuration and switching process of the network-side port may include:

step 701: the port configuration is initialized. When no configuration is performed, after the device is powered on and started, default initialization of the port is performed, and the network-side port initializes the resource configuration table information, which is performed in step 601. According to the port resource configuration table, port 4 is initialized to an ethernet type port, and port 5 is initialized to a flex port type. The port resource allocation module sends initialization configuration information to the port switching module, and the port switching module informs the logic chip to complete the initialization configuration of the network side port.

Step 702: configuring network-side port attributes.

The port 4 is initialized to be a flexE port, and the port can be further added to a flexE group, and then has the attribute related to the flexE port. And the switching control module creates a service model related to the flexE port according to the configuration information sent by the command processing module, sends the port switching module and further configures the logic chip. The port 5 is initialized to be an ethernet port, and attributes of the ethernet port, including a port name, a port number, a port rate, an optoelectronic attribute, an access mode, a jumbo frame support, and the like, may be further configured.

Step 703: traffic is bound to network side ports. The ethernet service or CPRI service on the access side may be carried on flexE shim. A flexE service configuration may be further created on the flex port on the network side. When creating service configuration, the port resource configuration module stores a port mapping table, which is shown in table 2 below, wherein an unsupported mapping combination is configured. Whether the corresponding port type is supported by the network side port can be judged by inquiring the port mapping table, and an error is returned when the corresponding port type is not supported. For example, the user side CPRI port type cannot be carried on the ethernet port on the network side. When expanding supported port typesA corresponding entry in the port mapping table needs to be added.

User side port types	Network side port types
		Ethernet network	Ethernet network
Cpri	FlexE
		Ethernet network	FlexE
Extended new port types	FlexE

Table 2 port mapping table

After passing through the port at the access side, the CPRI service message enters the corresponding service processing module of the logic chip for processing, and after the flexE service processing of the chip, the flexE message is transmitted at the network side. After the Ethernet service message passes through the port of the access side, the Ethernet service message enters the corresponding service processing module of the logic chip for processing, and after the Flexe service of the chip is processed, the Flexe message is transmitted on the network side.

Step 704: and switching the port types.

If the network side port needs to be switched to the Ethernet port, the service needs to be migrated, when the port switching of the network side is executed, the switching control module judges whether the service configuration is related according to the port number, the network side port configured by the related service does not allow the port switching, and the switching controller module returns error information to the command processing module. For switching a network-side port from a flexE port to an ethernet port, traffic needs to be migrated to other flexE ports, or the flexE traffic needs to be deleted, and the flexE port needs to be further removed from the flexE group. For switching the network-side port from the ethernet port to the flexE port, the ethernet traffic needs to be migrated to another port, or the traffic needs to be directly deleted. And returning error information when the network side port bound with the service is switched. After the service migration or deletion is completed, the command processing module notifies the switching control module after receiving the port switching command, the switching control module judges that the switching condition is met and further notifies the port switching module, and the port switching module notifies the logic chip to complete the switching of the port types.

For the case where a network-side port is associated with traffic, port switching may be performed by a forced switch command. When the forced switching is executed, the port switching module configures the service associated with the port binding deletion, issues a command for deleting the service to the switching execution module, and further completes the unbinding of the service and the port. And then, carrying out switching processing operation of the port type to finish the forced switching of the port type. Thus, the switching scene of the network port type is completed.
