In the description of the present invention, it should be noted that, if the terms "upper", "lower", "inner", "outer", and the like indicate an azimuth or a positional relationship based on the azimuth or the positional relationship shown in the drawings, or the azimuth or the positional relationship in which the inventive product is conventionally put in use, it is merely for convenience of describing the present invention and simplifying the description, and it is not indicated or implied that the apparatus or element referred to must have a specific azimuth, be configured and operated in a specific azimuth, and thus it should not be construed as limiting the present invention.

Furthermore, the terms "first," "second," and the like, if any, are used merely for distinguishing between descriptions and not for indicating or implying a relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

Referring to fig. 1, fig. 1 is an exemplary schematic diagram of an extended interface technology provided by an embodiment of the present invention, in fig. 1, a cascade port (te 0/1) of a central switch 10 and an uplink interface (te 0/1) of a satellite unit 20 are connected to form a physical link capable of communicating (as shown by a solid line between the central switch 10 and the satellite unit 20 in fig. 1), a user interface of the satellite unit 20 is connected to a user device 30, and the user device 30 may be a PC, a server, a wireless AP (Wireless Access Point, a wireless access point), a printer, a mobile terminal, or the like.

To multiplex the physical links (shown in solid lines in fig. 1), an extension identifier is set for each of the user interfaces of the satellite units 20, and one extension identifier corresponds to one virtual extension interface on the central switch, i.e. each of the user interfaces of the satellite units 20 and the extension interface of the central switch 10 are mapped to form a virtual data channel (e.g. a dashed line between the central switch 10 and the satellite units 20 in fig. 1) by means of the extension identifier. In fig. 1, there are 8 user devices 30, which are communicatively connected to the satellite unit 20 via 8 user interfaces (user interface gi 0/1-user interface gi 0/8) of the satellite unit 20, and for each user interface, 8 expansion interfaces (expansion interfaces gi 100/1-expansion interfaces gi 100/8) corresponding to the user interfaces are created on the central exchange 10. The virtual data channels indicated by the multiple broken lines share the same physical link indicated by the solid line when the actual data transmission is performed, and the physical link is used as an expansion interface channel.

For example, taking the user interface gi0/1 as an example in fig. 1, for the uplink traffic, the satellite unit 20 receives the uplink traffic sent by the user equipment 30 through the user interface gi0/1, marks the uplink traffic with an extension identifier 1, sends the uplink traffic to the central switch 10 through the extension interface channel, and the central switch 10 maps to the corresponding extension interface gi100/1 through the extension identifier 1; for downlink traffic, the central switch 10 finds the expansion interface gi100/1 as an outgoing interface according to the forwarding principle of the switch for the downlink traffic of the user interface gi0/1 of the satellite unit 20, the downlink traffic is marked with the expansion identifier 1, the downlink traffic is sent to the satellite unit 20 through the expansion interface channel, the satellite unit 20 identifies the expansion identifier 1 and sends the expansion identifier 1 from the user interface gi0/1 to the corresponding user equipment 30, thereby forwarding the uplink traffic and the downlink traffic is realized. The satellite unit 20 is only responsible for transparent forwarding of access traffic, and all traffic control, traffic control is done by the central switch 10. Thus, the network centralized control and the user distributed access are realized. Between the central exchange 10 and the satellite units 20, an auto-discovery and management protocol is run, including auto-discovery of the satellite units 20, user interface reporting and status management of the satellite units 20, extended identification allocation and maintenance of the user interfaces of the satellite units 20, etc.

It should be noted that, if the central switch 10 has a plurality of cascade ports and is capable of supporting a greater number of expansion interfaces, the central switch 10 may implement physical connection through the plurality of cascade ports and the plurality of satellite units 20, and one physical link exists between one cascade port and one satellite unit 20, and traffic forwarding between the central switch 10 and the corresponding satellite unit 20 is implemented by multiplexing the physical link.

As one implementation manner, the central switch 10 and the satellite unit 20 are externally presented as a distributed device, and one satellite unit 20 is a plug and play service board card of the distributed device, as another implementation manner, the central switch 10 and the satellite unit 20 may be mutually independent devices, so as to form a distributed system.

In the expansion technology of fig. 1, since each user interface corresponds to one expansion interface, and one expansion interface needs to occupy one hardware resource, the number of expansion interfaces that can be provided is greatly limited by the chip hardware specification limit. In view of this, embodiments of the present invention provide a method, an apparatus, a central switch, and a storage medium for processing a user service, which can fully utilize an expansion interface, save hardware resources occupied by the expansion interface, expand the number of user interfaces of a satellite unit managed by the central switch, and further expand the number of user devices that can be accessed by the satellite unit, and will be described in detail below.

Referring to fig. 2, fig. 2 is a block diagram of a central switch 10 according to an embodiment of the present invention, where the central switch 10 includes a processor 11, a memory 12, a bus 13, and a communication interface 14, and the processor 11, the memory 12, and the communication interface 14 are connected through the bus 13.

The processor 11 may be an integrated circuit chip with signal processing capabilities. In implementation, the user traffic handling method may be implemented by means of integrated logic circuits of hardware in the processor 11 or instructions in the form of software. The processor 11 may be a general-purpose processor including a CPU (Central Processing Unit ), NP (Network Processor, network processor), and the like; but also DSP (Digital Signal Processing, digital signal processor), ASIC (Application Specific Integrated Circuit ), FPGA (Field Programmable Gate Array, field programmable gate array) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components.

The memory 12 is used to store programs, such as the user service processing apparatus 100 in the following embodiment. Subscriber services processing device 100 includes at least one software functional module that may be stored in memory 12 in the form of software or firmware (firmware) or cured in the OS (Operating System) of central switch 10. After receiving the execution instruction, the processor 11 executes a program to implement the user service processing method disclosed in the present embodiment.

Referring to fig. 3, fig. 3 is a flowchart illustrating an example of a user service processing method provided by the embodiment of the present invention, and the method further provides a user service processing method applied to the central switch 10 in fig. 2, and includes the following steps:

step S101, acquiring service types of a plurality of user interfaces of a satellite unit.

In this embodiment, after planning the service type of the user interface according to the actual requirement of service deployment, the network planner configures the service type of the satellite unit user interface, where the configuration may be implemented on the controller, and then issued to the central switch by the controller, or may directly configure the service type locally in the central switch. The service type may be voice, video, print service, etc., e.g. a total of 8 user interfaces, user interface 1-user interface 3 is voice service, user interface 4-user interface 6 is video service, user interface 7-user interface 8 is print service, the service types of these 8 user interfaces include 3 types: voice, video, and printing. In the embodiment of the invention, the central switch can acquire the service type in the local configuration.

Step S102, creating one-to-one expansion interfaces according to the service types.

In this embodiment, one expansion interface corresponds to one service type, and a message with the same service type is processed through the same expansion interface, so that a user interface with the same service type only needs to correspond to one expansion interface, and occupies one hardware resource.

Step S103, the business of the user interface of the same business type is processed through each expansion interface.

According to the method provided by the embodiment, the user interfaces of the same service type can meet the communication requirement by sharing one expansion interface, so that the expansion interfaces are fully utilized, the hardware resources occupied by the expansion interfaces are saved, the number of the user interfaces of the satellite units managed by the central switch is effectively expanded, and the number of devices which can be accessed by the satellite units is further expanded.

In this embodiment, creating the one-to-one expansion interface includes creating a correspondence between the expansion interface and a service type, including configuration of a central switch and configuration of a satellite unit, where a specific implementation manner is:

setting a corresponding expansion identifier for each service type;

establishing a mapping relation between the expansion interfaces, the cascade ports and the expansion identifiers, wherein each expansion interface corresponds to one cascade port and one expansion identifier;

And configuring a mapping relation between the service types and the extension identifiers for the satellite units, wherein each service type corresponds to one extension identifier.

In this embodiment, the extension identifier can uniquely characterize a mapping relationship between the extension interface and the service type (or the user interface corresponding to the service type). Different satellite units may use the same extended identity. Depending on the hardware support of the device, the extension identifier may employ different techniques. For example, VLAN TAG technology (Virtual Local Area Network, virtual local area network TAG technology) is used, that is, the original data from the user interface is forwarded to the central switch 10 by adding a layer of VLAN TAG at the satellite unit 20, and the corresponding expansion interface is found by means of the VLAN TAG.

In order to more clearly illustrate the user service processing method of the first mode, please refer to fig. 4, fig. 4 is an exemplary diagram of an optimized expansion interface provided by the embodiment of the present invention, in fig. 4, there are 4 user interfaces of the satellite unit 20, each user interface is connected with a PC, the user interfaces of the PC1-PC2 are one service type, the user interfaces of the PC3-PC4 are another service type, the expansion identifier 2 is corresponding, the expansion identifier 1 corresponds to the expansion interface gi100/1 of the central switch, and the expansion identifier 2 corresponds to the expansion interface gi100/2 of the central switch.

After the processing of the first mode, each service type is provided with a corresponding extension identifier, the central switch creates a plurality of extension interfaces, and based on the optimization mode of the first mode, the embodiment also provides an implementation mode of the forwarding process of the uplink message and the downlink message in the optimization mode:

for the uplink message, one implementation manner is as follows:

receiving an uplink message from a corresponding expansion interface according to an expansion identifier of the uplink message sent by the satellite unit, wherein the uplink message is generated by the satellite unit according to a service message received through any user interface, and the uplink message comprises the expansion identifier determined by the satellite unit according to the service type of the user interface for receiving the service message; and the central switch performs service processing on the uplink message. Generally, there are two modes of service processing for the uplink message by the central switch, one is that the service is processed after the message processing is performed by the local uplink CPU; the other is to forward the uplink message directly, for example, to the remote device through an uplink interface.

In this embodiment, if the uplink packet is a packet that needs to be sent by the user equipment 30 through the central switch 10, the forwarding path is: the specific forwarding process of the user equipment 30-satellite unit 20-central switch 10 is as follows: the user equipment 30 sends the service message to the user interface of the satellite unit 20, the satellite unit 20 receives the service message through the user interface, determines the expansion identifier corresponding to the service type according to the service type of the user interface, the satellite unit 20 obtains the uplink message after marking the determined expansion identifier for the service message, and sends the uplink message to the central switch 10, and the central switch 10 finds the matched uplink interface to forward to the remote equipment by searching the forwarding table after receiving the uplink message through the expansion interface.

For the downlink message, one implementation is:

receiving a downlink message sent by remote equipment;

searching a forwarding table according to a destination address in the downlink message, determining an output interface matched with the downlink message as an expansion interface, marking the downlink message with an expansion identifier corresponding to the matched expansion interface, and sending the downlink message through the matched expansion interface.

In this embodiment, the downlink message is a message received by the central switch 10 and required to be sent to the user equipment 30, and the downlink message received by the central switch 10 is sent by a remote device, where the remote device may be a remote data center service, a server service, or the like. After the central switch 10 receives the downlink message sent by the remote device, its forwarding path is: the specific forwarding process of the central switch 10-satellite unit 20-user equipment 30 is as follows: the central exchange 10 searches the forwarding table according to the destination address in the downlink message, determines the output interface of the downlink message as an expansion interface, marks the expansion identifier corresponding to the matched expansion interface on the downlink message, sends the downlink message to the satellite unit 20 through the matched expansion interface, searches the user interface corresponding to the satellite unit according to the destination MAC address in the service message, hands the downlink message to the corresponding user interface, and the satellite unit 20 strips off the expansion identifier in the downlink message to obtain the service message and sends the service message to the corresponding user equipment.

In the first embodiment, the number of the satellite units 20 that the central switch 10 can connect may still not meet the requirement due to the limitation of the hardware of the central switch 10, so as to further expand the number of the satellite units 20 that the central switch 10 can connect, and further expand the number of the devices that the satellite units 20 can access, the embodiment further provides another implementation manner of creating a one-to-one expansion interface, namely, the second embodiment:

in the second mode, a cascade switch is introduced, and the central switch 10 is connected with a plurality of satellite units 20 through the cascade switch, so that the number of satellite units 20 that the central switch 10 can be connected with can be increased, and besides the mapping relationship between the expansion interface and the expansion identifier, the mapping relationship between the service type and the expansion identifier is configured for each satellite unit 20, the cascade switch is also configured.

The second mode is implemented in the same way as the first mode, that is: setting a corresponding expansion identifier for each service type; and establishing a mapping relation between the expansion interfaces, the cascade ports and the expansion identifiers, wherein each expansion interface corresponds to one cascade port and one expansion identifier.

In addition, for each satellite unit 20, in the second mode, a mapping relationship between a service type and an extension identifier corresponding to the satellite unit is configured for each satellite unit, and each service type corresponds to one extension identifier. For example, satellite unit 1 has 3 service types corresponding to extension id 1-extension id 3, respectively, and satellite unit 2 has 3 service types corresponding to extension id 4-extension id 6, respectively.

Since the second mode introduces a tandem switch, in order to enable the tandem switch to forward normally between the central switch 10 and the satellite unit 20, the tandem switch needs to be configured, and one implementation mode is as follows:

and configuring a mapping relation between each satellite unit and the expansion identifier for the cascade switch, wherein each satellite unit corresponds to at least one expansion identifier, and one expansion identifier corresponds to one satellite unit.

In order to more clearly illustrate the user service processing method of the second mode, please refer to fig. 5, fig. 5 is an exemplary diagram of another optimized expansion interface provided by the embodiment of the present invention, in fig. 5, the central switch 10 is connected to two satellite units 20 (satellite unit 1 and satellite unit 2) through a cascade switch, two user interfaces in the user interfaces of each satellite unit 20 are connected to a PC, the satellite unit 1 is connected to a PC11 and a PC12, the satellite unit 2 is connected to a PC21 and a PC22, the user interfaces corresponding to 4 PCs are different service types, and respectively correspond to the expansion identifier 1-the expansion identifier 4.

It should be noted that fig. 5 is only an example, and in fact, the cascade switch may also connect to more satellite units 20, and each satellite unit may also connect to more devices, where hardware allows.

It should be further noted that, since the cascaded switch in fig. 5 only needs to perform message transparent transmission, the configuration requirement is not high, and adding the cascaded switch does not increase excessive cost.

After the second mode is processed, each service type is provided with a corresponding extension identifier, a plurality of extension interfaces are established by the central switch, one-to-one interface identifier mapping relations exist between the extension interfaces and the cascade ports as well as between the extension identifiers, the satellite units are configured with one-to-one type identifier mapping relations between the service types and the extension identifiers, the cascade switch is configured with satellite unit identifier mapping relations between each satellite unit and the extension identifiers, and based on the second mode optimization mode, the implementation mode of the forwarding process of the uplink message and the downlink message in the second mode is further provided:

for the uplink message, one implementation manner is as follows:

receiving an uplink message sent by a cascade switch, wherein the uplink message is an uplink message sent by any satellite unit in a plurality of satellite units received by the cascade switch, the uplink message is generated by any satellite unit through a service message received by any user interface, and the uplink message comprises an extension identifier determined by any satellite unit according to the service type and type identifier mapping relation of any user interface;

And receiving the uplink message from the corresponding expansion interface according to the mapping relation between the expansion identifier and the interface identifier in the uplink message, and carrying out service processing on the uplink message.

In this embodiment, the forwarding path of the uplink packet is: the specific forwarding process of the user equipment 30-satellite unit 20-cascading exchanger-central exchanger 10 is as follows: the user equipment 30 sends the service message to the user interface of the satellite unit 20, the satellite unit 20 receives the service message through the user interface, determines the expansion identifier according to the service type and the type identifier mapping relation of the user interface, the satellite unit 20 obtains the uplink message after marking the determined expansion identifier for the service message, and sends the uplink message to the cascade switch, the cascade switch transmits the uplink message to the central switch 10, and the central switch 10 determines the uplink expansion interface from a plurality of expansion interfaces according to the expansion identifier and the interface identifier mapping relation in the uplink message and forwards the uplink message through the uplink expansion interface.

For the downlink message, one implementation is:

receiving a downlink message sent by remote equipment;

according to the destination address in the downlink message, searching a forwarding table, determining an output interface matched with the downlink message as an expansion interface, marking the downlink message with an expansion identifier corresponding to the matched expansion interface, transmitting the downlink message to a cascade switch through the matched expansion interface, searching the forwarding table by the cascade switch according to the destination MAC address in the service message to obtain the output interface, and transmitting the downlink message from the output interface to a satellite unit for forwarding.

In this embodiment, after the central switch 10 receives the downlink packet sent by the remote device, its forwarding path is: the specific forwarding process of the central switch 10-cascade switch-satellite unit 20-user equipment 30 is as follows: the central switch 10 searches the forwarding table according to the destination address in the downlink message, determines the output interface matched with the downlink message as an expansion interface, marks the expansion identifier corresponding to the matched expansion interface on the downlink message, sends the downlink message to the cascade switch through the downlink expansion interface, searches the forwarding table according to the destination MAC address in the service message to obtain the output interface, sends the downlink message from the output interface to the satellite unit for forwarding, and the satellite unit searches the user interface corresponding to the satellite unit according to the destination MAC address in the service message, and peels off the expansion identifier in the downlink message to obtain the service message and sends the service message to the corresponding user equipment 30.

In this embodiment, in order to improve service reliability during actual networking, a common manner is to perform device-level backup, and for device-level backup, an MLAG technology (Multi-Chassis Link Aggregation, cross-device link aggregation technology) is widely used, and the technology is mainly based on the principle that two central devices independently operate, a cross-device aggregation protocol is operated between two devices, a primary-standby state is maintained, an access device uses link aggregation, two uplink devices are respectively connected to two MLAG devices (refer to devices operating the MLAG technology), the two MLAG devices are respectively connected to the device under link aggregation ports, the link aggregation ports need to be configured with the same MLAG GroupID, link aggregation of the two ag devices is identified, the external presentation is the same link aggregation, and the link aggregation SystemID externally advertised by the two MLAG devices is a unified SystemID after protocol, so that the two MLAG devices are virtual devices in view of the access device. Thus, when two MLAG devices operate normally, the traffic of the access device is shared between the two MLAG devices, and when one of the two MLAG devices fails, the access device only forwards the traffic from the normal one of the two MLAG devices, so as to achieve the reliability of the device level, please refer to fig. 6, fig. 6 is a schematic view of MLAG networking provided by the embodiment of the present invention, in fig. 6, the MLAG master device and the MLAG slave device communicate through an MLAG protocol, the MLAG master device and the MLAG slave device are both connected with the access device in communication, corresponding to link 1 and link 2 in fig. 6, the access device is connected with PC1 and PC2 through different access interfaces, and the link 1 and link 2 are configured with the same ag mlgroupid, i.e., ag mlgroup 100, so that, for the access device, the MLAG master device and the ag slave device are one device, and the access device do not sense two devices in one master and one slave state.

Based on the MLAG networking of fig. 6, if the user service processing method provided by this embodiment is used in the networking, this embodiment provides an implementation manner, aiming at the network architecture of the central switch and the satellite unit, in order to achieve device-level backup, based on the MLAG technology, that is, two central switches form the MLAG, the upper link of the satellite unit adopts dual uplink, and distributes and connects two MLAG devices, because the number of expansion interfaces that need to be expanded by the central switch is relatively large (such as 4000), the link aggregation group of the devices is limited by hardware, and the number is limited (generally 512 at maximum), and the current existing technology makes the architecture limited in use. The specific method comprises the following steps: after the MLAG upper expansion interface management protocol detects that the satellite unit is on line, an instruction is issued, the satellite unit adds an uplink interface into a default link aggregation group, and the two uplink interfaces are aggregated into one aggregation group by adopting a static link. After the MLAG Master device (namely a main central switch) detects satellite units, a corresponding number of virtual expansion interfaces are automatically generated according to the number of user ports of the satellite units and an abstract interface service classification mode, MLAG GroupID is allocated to each virtual expansion interface, then the MLAG GroupID, satellite unit identifiers and satellite unit interface serial numbers are synchronized to the MLAG Slave device (namely a standby central switch), after the MLAG Slave device receives the information, the MLAG Slave device searches for expansion interfaces with the same satellite unit identifiers created by the device through the satellite unit identifiers, finds out the corresponding expansion interfaces according to the satellite unit identifier interface serial numbers, distributes the MLAG GroupID to the corresponding expansion interfaces, and forms a pair of virtual static link aggregation groups to communicate with the static link aggregation groups of the satellite units.

By using the user service processing method provided by the embodiment, the central switch can be connected with a larger-scale satellite unit number, a larger-scale user access number and a service access number. Under the network architecture, the satellite unit is only responsible for data forwarding and is not responsible for service control, such as 802.1X service, all service control is concentrated in a central switch, and high requirements are put on the performance of the central switch, which can restrict the actual effective scale of the network architecture.
